SPS panels provided many advantages on this project

1) Installation was very easy and took a

fraction of the time required for concrete 2) Eliminated winter heating requirements,

risk of freezing damage to finished surfaces and waste materials

3) Thinner panels gave more headroom (40mm vs.150mm for concrete)

I would highly recommend SPS and Intelligent Engineering.

SPS Citadel Access Protection May 2015

Background Citadel protection is a proven concept that has a successful track record for protecting ships and crew from piracy. The internationally recognised Best Management Practice to Deter Piracy in the Gulf of Aden and off the Coast of Somalia recommends that due consideration should be given to establishing a secure Citadel that “is designed and constructed to resist a determined pirate trying to gain entry for a fixed period of time”. SPS is an ideal product for Citadel hardening.

SPS Overlay Fuel Tank Conversion for 2015 Emissions Requirements

December 2014 Project Summary Three tankers needed thermal insulation boundaries installed between two Heavy Fuel Oil (HFO) tanks to create a Marine Gas Oil (MGO) tank as part of the shipowner’s strategy to meet new exhaust gas emission requirements. IMO MARPOL 73/78 Annex VI has been amended to require new standards for marine fuel oils when vessels are operating in defined Emission Control Areas (ECA), specifying a reduction of the sulphur content (SOx) to below 0.1% from January 2015. This was the first time that SPS Overlay had been used in this application; and was verified by Lloyds Register (LR). Carried out in Qatar, by Intelligent Engineering’s partner, CTS Offshore and Marine Limited, for a global shipping company, the three ships had areas of 50m² of SPS Overlay fitted to bulkheads between two adjacent fuel tanks.

Benefit of using SPS Overlay: • Cost effective insulation of

boundary between adjacent HFO and MGO tanks

• Maximum HFO and MGO tank capacity due to compact thickness of SPS

• No change to existing structure • Zero through-life maintenance

SPS Overlay Strengthening of Pontoon Shell Plating of John Shaw

March 2014

Project Summary

The semi-submersible oil platform “John Shaw” is one of many that have benefited from an SPS Overlay repair to solve a problem that is difficult to achieve by any other means. At the time of repair, the vessel was floating alongside and the repair location was several meters below the waterline making conventional “crop and renew” method impossible without a costly and unscheduled dry-docking. During normal operations semi-submersible platforms occasionally receive minor contact damages from positioning tugs and offshore support vessels, particularly in heavy swells. SPS Overlay was installed in way of two such areas to protect and reinforce the hull plating. In this application, SPS Overlay provides a class-approved permanent repair without the need to dry-dock the platform, saving the operators additional time and maintenance costs associated with an unscheduled docking.

SPS Overlay provides an innovative solution to minimising operational risk and extending the service capability of self-elevating wind turbine and installation vessels. These specialist ships must be capable of safe operation in a wide variety of environmental conditions. In particular, submerged rocks on the sea-bed represent a significant risk to safety and operational integrity. SPS’s inherent resistance to impact and concentrated loads provides a technically superior solution which is fast and cost-effective to apply. SPS Spudcan Reinforcement delivers: • Increased structural protection from concentrated loads caused by contact with large rocks on the sea bed. • Reduced operational risk and extended ship service capability.

SPS Overlay Thermal Insulation in EOR Tanks of New Build FPSO Quad 204

November 2013

Project Summary

A special fluid is injected into the well to increase the oil recovery. However, the fluid is heat sensitive (coagulates at elevated temperatures); and because the Enhance Oil Recovery (EOR) tanks are adjacent to the fuel oil tanks (usually maintained at around 60 degree C) there is a concern. The EOR fluid is circulated in the tanks to prevent “hot-spots”. BP required the tank walls to be insulated for safety reason. The internal surfaces of the EOR tanks are stainless steel (clad/explosion bonded SS/CS plating) with a thermal resistance through SPS Overlay (R-value) is 0.2819 m²C°/W.

SPS Overlay and Penguins at Antarctica Inhibit Future Crack at Fuel Oil Tank Plating of Aurora Australis

May 2013

Project Summary

The ice breaker research vessel Aurora Australis travels between Australia and Antarctica transporting essential fuel and supplies to the research team. SPS Overlay was used to solve a historical fatigue crack problem that periodically affected a knuckle joint in the bulkhead separating the fuel oil and water ballast tanks. This can lead to a risk of contamination of both fuel and water ballast, which would have a serious impact on vessel operations. Used in this location, SPS Overlay significantly reduces the local stress levels and virtually eliminates the risk of further fatigue in the knuckle joint. At the same time, SPS Overlay provides an extra barrier, giving a second level of defence against future fuel and ballast water contamination.

Project Summary

SPS Overlay was applied to the upper surface of the sloping trunk deck on a LNG Floating Storage Unit. The objective was to restore the structural properties of the steel plating and stiffeners which had suffered corrosion due to condensation build-up in the enclosed void space above the LNG tanks. The use of SPS Overlay allowed a safe, fast and unhindered repair, while the low-heat-input operations, made possible by the unique design of the Overlay repair, avoided damage to the cryogenic membrane containment system located directly beneath the sloping deck.

a) During Test b) After Test

2. SPS Floors with Intumescent Protection An indicative fire test has been conducted on 4-50-4BC SPS Floor with a thin film intumescent coating: Interchar 2060 at 1mm thickness. The test comfortably passed 2 hours fire resistance. The SPS Floor is scheduled to be tested in accordance with BS EN 1365-2 at BRE Global. Interchar 2060 from International Paints is an industry standard intumescent widely used on structural steel: it gives a hard, durable coating, ideal for factory application to SPS panels.

Terraces

SPS Terraces are designed for each application to provide suitable static and dynamic responses for the relevant spans, applied loads and venue use. Terrace stiffness and natural frequency, which are typically key design criteria, can be changed by selecting the appropriate thicknesses of the terraces’ metal faceplates.

Design

Materials Faceplates: Steel (S235)

Core: Polyurethane

Geometries Possible SPS Terraces are custom made to suit each venue with geometries designed to suit each area of the bowl including facetted corners and parabolic bowls

SPS Specification 4-20-4

Steel Grade 235

Tread (mm) 800mm for all scenarios shown (different tread widths can be provided)

Span (m) 6.00 7.65 9.00

Rise (mm) ≥200 ≥250 ≥300

Weight (kg/m2) ≥106 ≥109 ≥113

Natural Frequency (Hz) 10 9 7

Deflection (L/-) 400 350 300

Note: Unit weight is quoted as kg/m2 on plan and varies with terrace geometry and specification.

Note: Natural frequency is for the bank of SPS Terraces only and must be combined with the natural frequency of the supporting frame to assess the natural frequency of the whole stand.

Performance & Quality

Typical Service Loads

SDL: 0.75 kN/m²; LL: 5 kN/m² (other load combinations readily accommodated)

Ultimate Capacity Ultimate capacity of SPS Terraces is equal to plastic capacity of steel faceplates in bending and exceeds the effects of standard imposed building loads (greater than 10 kN/m²).

Stability SPS Terraces act as diaphragm. Lateral forces are transferred through the bolted connection between the terrace treads and the stools attached to the raker frame which then distributes these forces to the lateral load resisting system.

Fire Resistance

Up to 120:120:120 minutes using conventional fire protection which is either factory or field applied. The thickness of the protection is tailored to the period of protection required.

(Note: The fire engineering can be used to show that, given the rapid evacuation requirements of venues, SPS Terraces do not require fire protection to provide a safe structure during a fire.)

Acoustics SPS Terraces offer similar acoustic performance to concrete terraces for reflection, transmission and impacts.

Coating

SPS Terraces are factory coated with epoxy or polyurethane systems to meet venue “life-to-first-maintenance” requirements within the local environment. Typically, 150 microns on all faces for a 15 year requirement in a C3 environment.

The treads of SPS Terraces are coated with an additional 75 micron non-slip layer.

SPS Terraces are typically grey (or black for indoor concert venues) but can be provided in any RAL colour.

Watertight Seals

Joints on the rises of SPS Terraces are naturally watertight.

Joints between adjacent bays of terraces directly above the rakers are made watertight by a continuous tape that runs from the top to the bottom of the bank. The tape is adhered into a recess at the edge of each tread.

Geometric Tolerance ±3 mm over 10m Flatness ±3 mm over 3m

Note: All performance characteristics proven by full-scale independent tests. Full performance documentation available. Design guidelines and engineering models also available.

Detailing

Rise to Rise Connections

Socket Button Head Bolts, Tension Control Bolts, Lindapter Hollobolts or Structural Rivets used to connect overlapping steel rises using factory drilled holes typically set at 500mm centres. All central rises of factory assembled double or triple banks fully bolted prior to shipping.

Tread to Raker Connections

Hexagonal Head Bolts are used to connect treads to top flange of raker stools. Bolt holes in treads factory made with recess to allow head of bolt to sit in depth of tread and be covered with steel capping plate finished to match tread.

Front & Rear Connections

The fore or rearmost rise of the bank of SPS Terraces are either supported by structural hollow sections or connected to concrete slabs using expansion anchors.

Upstands A forward upstand can be created in factory by welding vertical SPS panel to front of foremost tread prior to coating. Top of upstand can be fitted with variety of railing details.

Seat Brackets Seats can be attached to the rise or tread of SPS Terraces. For rise mounted seats, bolt holes are pre-drilled in the factory (field drilling possible if required). For tread mounted seats, insert plates are welded as required into during the manufacturing process to accommodate connections.

Balustrades and Rails

Rails can be attached to the rise or tread of SPS Terraces. For rise mounted rails, bolt holes are pre-drilled in the factory (field drilling possible if required). For tread mounted rails, insert plates are welded as required into during the manufacturing process to accommodate connections.

Insert Steps Single or double insert steps can be supplied and are made from folded steel plates with acoustic damping placed inside. The steps are fully coated to the same finish as the terraces with nose highlighting. The steps can be manually lifted into place and are adhered to the treads.

Fit-out M&E details are attached to the SPS Terraces with Hilti studs or Tek screws.

Penetrations We aim to make penetrations in factory before shipping. On site, penetrations can be made using industry standard core drilling or cold cutting methods.

Drainage Treads are sloped at 2° down towards the front of the terrace and drained at the lowest terrace which may have reverse slope. Drainage holes are incorporated in or between the treads.

Delivery & Erection

Off-site Manufacture & Finishing

SPS Terraces delivered to site as fully finished, coated and incorporating as many details as is practical. Apart from bolting and joint sealing no work to the terraces is required on site.

Delivery SPS Terraces are delivered to site on flat bed trucks stacked in order of a defined erection sequence. Between 30-45 SPS Terraces, pre-assembled as doubles or triples, can be delivered per truck depending on their length and weight.

Erection Trade Single trade erection, typically by same steel erector as frame. All connections to frame use industry standard bolting – no additional crew training required.

Crew Size 4 erectors for panel lifting, aligning and fitting initial bolts. 4 erectors to complete bolting, adhere sealing strip above raker and fix insert steps.

Erection Equipment Crane: typical lifts between 1.5 and 2.5 tonnes. Scissor lift: for bolting from below (if required). Lifted with: vacuum lift; or chains with threaded lifting eyes using factory made holes in the treads.

Installation Rate 600-900 seats erected/day/crane (assuming 15 to 20 lifts/day) as part of frame steel erection.

Through-life

Penetrations In-situ penetrations carried out with magnetic based drills, core drills or cold saws. Procedure is quick, dry, dust free and causes limited disturbance. Cut piece is light and easily removed.

Demountable (Demolition)

SPS Terraces should be unbolted and lifted off the frame. The supporting steel frame is then readily unbolted and can be re-used rather than demolished and recycled.

Reuse SPS Terraces can be recoated and reused on future venues.

Recycling Both the steel and polyurethane elements of the SPS Terraces can be recycled. The steel is recycled within the steel market. The polyurethane is crushed and used as filler in future SPS panels.

Performance

Typical Service Loads

SDL: 1.5 kN/m²; LL: 4.5 kN/m² (other loads and combinations readily accommodated)

Deflection Typically less than L/750 (for widths and live load listed above).

Dynamic Response The stiffness of SPS panels and supporting beams are adjusted to meet the needs of a particular building or room (e.g. Rfactor 6 is readily achieved for office floors).

Point Loads Once bolted in place, SPS Floors are readily able to carry most typical wheel loads from equipment such as cherry pickers, scissor lifts, fork lifts etc.

Ultimate Capacity Ultimate capacity of SPS Floor panels is equal to plastic capacity of steel faceplates in bending and exceeds the effects of standard imposed building loads (greater than 7.5 kN/m²).

(Note: Ultimate capacity of beams is not covered by this data sheet)

Composite Action Achieved through bolts connecting edges of SPS Floor panels to top flanges of supporting beams. Welded connections also possible.

Stability SPS Floors panels transfer diaphragm forces to the lateral load resisting system via bolts connecting edges of panels to top flanges of supporting beams. Welded connections also possible.

Fire Resistance

Up to 120:120:120 minutes using conventional fire protection which is either factory or field applied. When shorter periods are required the thickness of the protection is reduced accordingly.

(Note: an untreated SPS panel achieves an inherent 30 minute resistance with a 20mm core thickness, and 60 minutes for 25mm and thicker cores.)

Acoustics

Finished floors incorporating SPS Floor panels meet standard acoustic insulation requirements for airborne, impact and flanking noise for all conventional building types. For instance: SPS Floor design for hotels and offices provides: 49 dB of airborne sound insulation; and 46 dB of impact sound absorption provided standard hotel finishes are applied

Note: All performance characteristics proven by full-scale independent tests. Full performance documentation available. Design guidelines and engineering models also available.

Introduction Sandwich Plate System (SPS) is a structural floor plate comprised of two steel faceplates bonded together with a polyurethane elastomer core. Integrated steel perimeter bars contain the elastomer. The plates are generally bolted through the bars and act compositely with the supporting beams. SPS is an alternative to both stiffened steel, reinforcing concrete and composite concrete decking. SPS delivers a high stiffness to weight ratio and improved performance.

SPS achieves its thin dimension and low weight by utilising the elastomer core which transfers shear between each faceplate and prevents local buckling. Flexural strength and stiffness can be tailored to meet the specified structural requirements by selecting the appropriate thicknesses for each sandwich element. This datasheet assists the selection of panel thickness for different design criteria.

More than 200,000 m2 of SPS has been successfully used in building floor and wall configurations, shear walls, blast walls, as well as ships, bridges and stadium terraces. All structures are designed and produced to relevant codes and standards. SPS Floors provide an effective economic alternative to reinforced concrete or composite concrete/decking floors with identified benefits listed below.

Generally SPS floor plates are rectangular in plan but other shapes are possible (trapezoidal, curved edge etc).

Notes for the Load Span Tables: • These load span tables can be used for preliminary selection of SPS panel sections. The spans given are

based on deflection criteria as these govern. The span is defined as the distance between supporting beams. • Designs are in accordance with BS/EN 5950.

• Applied loads include all superimposed dead and live loads other than SPS panel self weight.

• Unit mass of SPS panels is based upon an elastomer density of 1150 kg/m3 and a steel density of 7850 kg/m3.

(Unit mass calculations exclude the weight of panel perimeter bars which typically weigh 10 kg/m.) • Tables are included for deflection limits of L/360 and L/750. Recommended limits for different uses are given.

The more stringent limits are to provide acceptable dynamic performance. • Tables for differing loads and deflection limits are available from Intelligent Engineering upon request.

• Spans calculated assume a one way spanning panel with an aspect ratio greater than 3.

• A fully detailed design can be developed from BS/EN 5950 in conjunction with the recommendations given in

“Engineering Design Guidelines for SPS Floors” available from Intelligent Engineering upon request. • Tables are provided for solid core and bubble core panels. A solid core contains 100% elastomer. A bubble

core has approx. 50% of the elastomer displaced by hollow polypropylene balls of a diameter equal to the core thickness, thus reducing the weight of the panels and minimising the quantity of elastomer.

• In most design instances, there will be a suitable option using either solid core or bubble core panels for any

given superimposed load and required span. The selection of the preferred option will be a function of the desired panel thickness, weight and product cost. IE will advise as required.

• SPS panels provide diaphragm capacity.

• Beams can be made composite with the SPS panels using bolted connections.

Saar River Bridge, Mettlach, remediation and repair

The judges' reasoning The sandwich plate system (SpS) steel-elastomer-steel composite plate (integral plate) is an innovative development by Stephan J. Kennedy (Canada), which is used in a variety of engineering disciplines (shipbuilding, offshore, civil engineering). As a result of the operating strength problems associated with orthotropic deck slabs and concrete or steel composite decks, Eiffel Deutschland Stahltechnologie GmbH (Hanover) reconfigured the SPS to meet today's demands and standards and developed it further. This creative adaptation was

managed in cooperation with major research centres and by employing extensive test series. Following initial prototypes, a remediation and refurbishment project has now been successfully implemented on the operational Saar River Bridge at Mettlach, Germany. Under running traffic conditions, the concrete deck was significantly lightened using SPS. This allowed the existing stays to be retained without reinforcement and thus the traffic load capacity to be substantially increased (upgrading). The intelligent installation concept should be emphasised. As a pilot scheme, the awarded structure is of strategic relevance to the maintenance and refurbishment of operational bridges.

Remit

Remediation of the Mettlach suspension bridge became necessary because the concrete deck was displaying serious damage and fractures were identified on one of the stays. The bridge needed to be lightened in order to increase the capacity of the stays and allow upgrading from bridge loading classification BKL 30/30 to 60/30. The remediation measures comprised two construction stages. During the first stage the concrete deck is replaced by the

innovative SPS (steel-elastomer-steel composite plate). This measure allowed the deck weight to be reduced from 500 t to 200 t. During the second construction stage the footpaths and corrosion protection were renewed. Cracks in the primary structure were identified at this stage. The main girder flanges and web connections therefore needed to be successively replaced by new assemblies. The cross girders were refurbished by means of bolted reinforcing assemblies.

Description of the main bearing structure The Mettlach bridge is a two-lane suspension bridge with a span of 108 m and footpaths attached on both sides. The primary bearing structure consists of two stays with 12 suspender ropes each, two main girders and 51 cross girders. The original main bearing structure was divided into 12 segments with riveted connecting joints. The existing reinforced concrete composite system carriageway was replaced by 104 steel-elastomer-steel composite system (SPS) deck panels. The downstream footpath was widened by 1.5 m and now also includes a cycle path.

Design The SPS carriageway, newly designed for the first construction stage, consists of 104 panels. They are bolted to the existing cross girders using a supporting framework, which is designed as an elastic rod joint. The innovative SPS construction method was licensed for use in Mettlach by an individual case approval process. In order to repair the main bearing structure a stiffer welded structure, comprising 60 mm flanges with 20 mm web plate stubs, was integrated in the existing structure of main girders consisting of a combination of rolled sections and plates. To achieve this, approximately 50 t of old, S235 structure was replaced by 120 t of new, S355J2 structure. In addition, the cross girders and cantilever brackets were refurbished using additional web reinforcements and bracket clamps to relieve the load on the structure and as corner bracing. Material selection

The 24 cm thick reinforced concrete composite carriageway slab was replaced by the sandwich plate system (SPS), a mere 4.5 cm thick, in a combination of steel panels with an elastomer core. A double layer of melted asphalt was applied to form the bridge surface. The footpaths are executed as pure steel structures with thin reactive resin surfaces. All reinforcing and new structures consist of S355J2 steel. Special engineering achievement To facilitate remediation of the bearing structure an installation concept was developed in which the elements of the main bearing structure, consisting of the supporting carriageway and the main girder flanges, were removed piece by piece, temporarily replaced and subsequently exchanged for a new construction. The entire measure was implemented under running traffic conditions. The adopted solutions, developed at short notice, needed to be suitable for the specific bearing response of the Mettlach

suspension bridge in terms of stresses and form compatibility. Despite the very limited accessibility it was possible to integrate the additional and complex remediation of the bearing structure in the footpath and corrosion protection renewal works. What positive effects does the special engineering achievement have? Using the adopted innovative carriageway design and installation technology it was possible to reduce disturbances to the regionally important transport route to a minimum. Successful remediation has reduced the weight of the carriageway from 500 t to 200 t. As a result of this the bridge loading classification was increased to BKL 60/30, thus eliminating the previous heavy traffic restriction. Remediation of the Saar River Bridge at Mettlach is a good example of sustainable construction. It was possible to upgrade the listed structure to meet today's traffic requirements.

Lightweight composite steel plate and elastomer deck shaves months off project schedule and millions off budget.

CITY OFFICIALS RECENTLY were able to both save a his-toric Edmonton bridge and avoid massive structural repairs and upgrades by opting for a lightweight steel deck system over-laid with asphalt instead of the traditional concrete replacement deck. The system uses composite panels consisting of steel plates with a solid elastomeric core. Although the material has been used in shipbuilding for years, its use in bridge construc-tion is relatively new. In addition to providing an effective and economical solution, using this steel deck system also cut con-struction time signifi cantly.

Bridge HistoryThe North Saskatchewan River winds its way from the Rocky

Mountains, across Alberta, and through the heart of Edmonton on its way toward Lake Winnipeg. Its shores have been popu-lated at Edmonton by aboriginal peoples for millennia, with the fi rst European infl uence appearing in the late 18th century. During World War II, Edmonton acted as a staging area for construction of the Alaska Highway, and today is the capital of Alberta with a regional population of over one million.

Historic Dawson Bridge has been a vital link for the people of Edmonton for generations, entering its 100th year of service in 2011. Originally known as the East End Bridge, it is a fi ve-span riveted steel through-truss with a clear width of 26 ft, 8 in.

and a total length of 776 ft: three spans of 142 ft, a navigation span of 250 ft, and an east approach span of 100 ft.

Originally constructed to carry horse-drawn wagons and electric trains to the Dawson Coal Company mine located on the east bank, the bridge opened on October 8, 1912 with a construction cost of $145,000. Only the second bridge to cross the North Saskatchewan River at Edmonton, Dawson Bridge quickly became a vital link for the city’s growth, allowing coal to be transported quickly into the heart of the city for industry and home heating.

After closure of the Dawson Mine in 1944, the bridge was converted to carry only highway vehicles. Today, the bridge has one lane of traffi c in each direction and accommodates about 17,000 vehicles each weekday. As a link to Edmonton’s extensive multi-use river valley trail system, the two sidewalks on Dawson Bridge serve many pedestrians and cyclists.

Condition AssessmentIn 2007 the city of Edmonton commissioned Dialog to con-

duct a condition assessment for Dawson Bridge.

replacement in order to increase the service life of the bridge and meet the target reliability indices of the Canadian Highway Bridge Design Code 2006. In addition, the original narrow side-walks—only 5 ft wide—caused safety problems due to mixed use by pedestrians and cyclists.

Especially problematic was the existing 6½ -in. steel-fi ber reinforced semi-lightweight concrete deck, cast in 1986 on top of old timber subdecking from the 1940s. Though its relative light weight was benefi cial for limiting dead loads, the thin concrete deck was too fl exible to resist cracking. In particular, the city had continual maintenance problems with the methyl

General plan from 1913 of the East End Bridge, now known as the Dawson Bridge, in Edmonton, Alberta, Canada.

With an overall length of 776 ft, the Dawson Bridge consists of fi ve simply supported trusses that cross the North Saskatch-ewan River on the east side of Edmonton.

The Dawson Bridge rehabilitation included upgrading critical con-nections by replacing the original rivets with high-strength bolts.

methacrylate membrane wearing surface at details where the concrete deck passed over the transverse fl oor beams. The con-crete deck section was reduced to only 2½ in. thick to clear the top fl ange of the fl oor beams, making it nearly impossible to control cracking.

As part of the assessment, a load rating of Dawson Bridge was conducted using a 4-axle, 63.5 ton Alberta CS3 rating vehi-cle, the largest vehicle that might practically access the bridge considering its vertical clearance restrictions and location. That assessment concluded that numerous truss members required strengthening or replacement to meet the required level of safety and to extend the life of the bridge.

As options for rehabilitation were developed, it became clear that the bridge could be rehabilitated economically only if a lightweight deck replaced the existing deteriorated deck. A traditional concrete deck would require costly replacement or strengthening of many truss members along with diffi cult

upgrading of existing connections. Additionally, it might over-load the piers, abutments, and foundations. The design team concluded that replacing the existing semi-lightweight concrete deck with a lightweight steel deck would allow the dead load savings to be applied to carrying additional live load and wid-ening the sidewalks. Only steel offered viable lightweight deck options: grating, orthotropic deck, or an innovative composite steel plate and elastomer system called the Sandwich Plate Sys-tem (SPS) developed by Intelligent Engineering (Canada) Ltd.

Grating was quickly eliminated as an option for the deck because increased road noise would be detrimental to the nearby Riverdale community. Orthotropic steel deck was judged a suit-able option, but detailing would be challenging where the deck had to clear the tops of the floor beams without raising the grade line. There also were concerns about its susceptibility to fatigue cracking. After considerable research, the design team recommended the patented SPS solution, judging that SPS technology offered the best combination of light weight, thin profile, and ease of erection for the Dawson Bridge Rehabilita-tion project.

Innovation and Risk ControlThe SPS composite steel plate and elastomer system was

originally developed by UK-based firm Intelligent Engineering Ltd. for ship hulls and decks in the marine industry. Application of this technology in the bridge industry began about a decade ago. After its use on several bridges around the world, SPS tech-nology is gradually gaining acceptance by bridge engineers.

SPS makes use of two relatively thin steel face plates con-nected by an injected thermosetting elastomer core. The final product is a composite panel with high stiffness and strength, but relatively low weight.

Deck panels are fabricated in the shop using conventional steel fabrication techniques. First, solid “perimeter bars” are welded along each edge of the bottom plate using a continuous fillet weld. The top plate is then lowered onto the perimeter

bars and fillet welded all around forming a panel with a sealed void. The liquid elastomer, which cures into solid form within an hour, is injected through a port to form the core. For Daw-son Bridge, the 3⁄8-in. steel face plates sandwich a 1-in. elasto-mer core, forming a composite deck panel with a total thickness of only 1¾ in. These prefabricated panels are typically 6 ft, 1 in. wide and 28 ft long.

Risk is inherent in the application of all new technologies in all industries. Perceived risk and its associated liability often dissuade engineers from trying innovations that might advance the state of the art in their area of practice. Potential liabil-ity places a constriction on the pace of innovation that, in the long run, is most often a disservice to society. Striking the right balance between innovation and risk control is the key to suc-cess. Thus, when Dialog recommended SPS—a relatively new technology—to the City of Edmonton, that recommendation came with the proviso that an intensive risk control program must be implemented, especially because Dawson Bridge is an important and expensive asset. As a progressive bridge owner, the city welcomed that innovation and directed the design team to proceed with SPS as the basis of design for the deck.

The risk control plan developed for the deck comprised six key elements:

Extensive background research in the available literature;Site visits by the design team to other bridges with SPS

decks, and interviews with the bridge authority managing those structures;Development of improved connection details in consulta-tion with Intelligent Engineering;Fatigue testing of full-scale sample connections in the

laboratory;Enhanced quality control and quality assurance programs during deck fabrication and erection; and,Monitoring of deck performance over the lifetime of the bridge as part of the Edmonton’s bridge maintenance program.

Dialog judged the most important aspect of the risk control

plan to be the development of new connection details between adjacent SPS deck panels. Of the handful of bridges around the world built using SPS technology, all have involved significant field welding—a method that is costly and makes quality control difficult. Risks associated with field welding include fit-up out-of-tolerance, the potential for excessive heat input that might debond the elastomer from the steel, and undesirable weld flaws that might inadvertently result in premature fatigue cracking.

Taking to heart the golden rule “shop weld and field bolt,” the Dialog design team developed unique bolted details for connecting the SPS deck panels that completely eliminate the need for field welding. Bolted connections drastically increase speed of erection, significantly reduce cost, and improve fatigue performance from Detail Category D (depending on the spe-cifics of the weld geometry) to Detail Category B when using slip-critical connections.

To connect adjacent SPS deck panels, a top splice plate is fastened by a single row of countersunk pretensioned ¾-in. ASTM A325 bolts. Countersunk bolts provide a flat surface for the finished deck, except for the thickness of the splice plate itself. This surface, once grit blasted, is prepared to receive a waterproof membrane and asphalt.

Longitudinal deck splices are designed to align with floor stringers below. This arrangement enables the top flange of the stringers to act as the bottom splice plate for the connection, saving both weight and complexity. The new stringers chosen—W18×50—are larger than required for flexural strength but offer a flange wide enough to accept a row of bolts on each side of the web. At transverse deck joints, located away from floor beams to avoid clashes, bolted splice plates are used both top and bottom. In all cases enough bolts are used so that sealing requirements are met and negative moments in the deck can be transferred across the supporting stringers. This very simple approach to connections makes the deck very easy to fabricate and simple to erect. Using similar bolting details, the traffic barriers along the length of the bridge are also bolted down through the deck to the edge stringer.

Also as part of the risk control plan, three small 1:1-scale samples of the longitudinal bolted deck connection detail were built and tested under fatigue loading at the University of Alberta with the assistance of professor Gilbert Grondin, P.Eng., Ph.D. Those tests demonstrated that the new connec-tion detail can withstand fatigue loads nearly double in magni-tude to those expected in actual in-service conditions.

Reaping the Benefits of InnovationBecause the composite steel deck panels could be fabricated

entirely in the shop and bolted quickly into position on the bridge, erection of the deck was completed in only six weeks during July and August 2010. This speed allowed the $17 mil-lion rehabilitation to be finished in only 12 months: the bridge closed to traffic on January 4, 2010, and reopened on December 20, 2010. A traditional concrete deck would have extended the project schedule to at least 18 months, added millions of dollars of extra truss strengthening work, and caused numerous other technical issues.

The Dawson Bridge project has successfully advanced the state of the art in bridge technology and has achieved cost sav-ings for the City of Edmonton, while allowing the rehabilita-tion work to be completed within a single construction season. Today, Dawson Bridge is fully rehabilitated with the world’s largest SPS deck—the only installation built entirely without field welding—and it stands prepared to serve Edmontonians for many generations to come.

Edmonton, capital of the Canadian province of Alberta, has a population of over a million. The historic Dawson Bridge today carries an import-ant traffic artery that was so important for the city’s industrial growth in the last century. Built in

1912 and initially used for the transportation of coal, the two-lane bridge today handles some 17,000 vehicles per day.

In 2007, a detailed structural examination commissioned by the city revealed that the entire almost century-old deck had to be replaced along with some of the members of the steel trusses. The steel structure was in need of repainting, and the very narrow sidewalks were a source of safety prob lems as well.

Making light work of a burdensome problem.

After an examination of all options, it soon became clear that the best rehabilitation approach was to limit the bridge’s dead load with a lightweight deck – a traditional concrete deck would have been too costly and too heavy for the aging existing steel structure. The design team therefore recom-mended an entirely new, lightweight sol ution, the Sandwich Plate System (SPS) from Intelligent Engineering Ltd. This re- presented the best possible combination of weight savings, a thin profile and simple and above all swift execution of the job. As this is a pretty new technology, the city was also recommended an extensive risk control package, which SPS effortlessly satisfied on all counts.

New lease on life for an old bridge – achieved with 70 percent less weight than with reinforced concrete.

Originally developed for the marine industry, SPS technol-ogy is now also finding applications in the construction of bridges and of stands in stadiums. 776 ft long and 26.8 ft wide, the Dawson Bridge is so far the first major bridge project to have made use of SPS technology. No less remarkable is that it does entirely without welding.

SPS itself consists of two steel face plates sandwiching a core of polyurethane. The finished product is a composite panel of high rigidity and strength. Thanks to the elastomer core, the PU system Elastocore ®, SPS also absorbs vibra-tion and displays high tolerance to jolts and impacts. SPS panels weigh up to 70 percent less than reinforced con-crete while being at least as strong and more durable in addition. Consequently, today’s bridges with SPS panels may yet be used by our grandchildren.

Faster construction, less stress and lower costs – SPS is the best solution in every respect.

SPS panels can be prefabricated off-site and are then bolted together on the bridge. The overall rehabilitation of this bridge was accomplished at high speed – without time-consuming welding and without annoying, long-term closures to traffic.

The bridge deck was replaced in just six weeks, in July and August 2010. The entire project was com-pleted in only 12 months from January to December 2010. A trad-itional bridge repair would have taken at least 18 months and have been much more expensive be-cause of the additional steel mem-

ber replacements. Michael Kennedy, CEO of Intelligent Engin eering, was delighted that the project has won the CISC Award for excellence in steel structures: “To have success fully completed this project in the city where the three founders of IE went to college and where SPS was initially developed makes it a special achieve-ment.”

on the threshold of a new era

We established Intelligent Engineering more than 10 years ago to develop and commercialise what we call SPS. Others have called SPS “the first new materials technology for heavy engineering in150 years” and described it as “bringing the maritime and civil engineering industries to the thresholdof a new era”.

In the decade since, we have spent more than 500 professional man-years and more than $100mconducting thousands of tests, proving and re-proving every aspect of the performance, economics,safety and sustainability of SPS. Together with our partners at BASF, the world’s largest chemicalcompany, we have developed 84 different groups of patents. We have built up a team of more than60 professionals working out of offices in Europe, North America and Asia, supported by an AdvisoryBoard of leading experts and businessmen.

We have completed more than 440 projects and have more than 280,000m2 of our product inservice. We have secured the approval of key regulatory authorities around the world and we havedemonstrated, by example, that SPS makes maritime and civil engineering structures, such as ships,offshore platforms, bridges and buildings, stronger, lighter, faster to build, longer lasting, safer, moreenvironmentally friendly and less expensive. What next?

In the decade to come, we will roll out SPS through a series of strategic partnerships, such as ourjoint venture with DSME, the world’s second largest shipbuilder. We will provide new applications, suchas blast and ballistics protection for those young men who may still be in harm’s way. We will provideeconomic and sustainable solutions in new markets, such as India and China. We will continue toinvest and to advance the frontiers of SPS.

When you take your son to a football match or your daughter takes you to a rock concert or whenyou take a lift in a tall building or a bridge or a ship across a river or an ocean, SPS will be there.

what is SPS?

SPS is a structural composite comprising two metal plates bonded with a polyurethane elastomer core.

SPS is much simpler and more robust than stiffened steel plate and much lighter and faster to erect than reinforced concrete.

SPS is used in a wide variety of applications including structural flooring, stadia and arena terraces, ship repair, shipbuilding and bridges.

Maritime applications

In maritime structures, such as the hulls and bulkheads of ships,load-bearing plates are usually made from steel, which is heavilystiffened to prevent buckling. SPS eliminates the stiffeningelements, making these structures much less complicated andmuch less prone to fatigue and corrosion.

Civil applications

In civil engineering structures, such as the decks of bridges andfloors in buildings, load-bearing plates are usually made fromreinforced concrete. This is because it is difficult to control fatigueand vibration using steel and, with the exception of long-spanbridges, the weight penalty of using concrete is tolerated. SPScontrols fatigue and vibration and is much lighter than concrete.In addition, SPS plates are prefabricated to a high degree ofdimensional accuracy. Using SPS plates reduces ‘wet-work’ onsite and de-risks and accelerates the build programme.

Repair and conversion

SPS can also be used to reinstate or strengthen existing platestructures, such as the cargo holds of ships and the decks ofbridges, in a process called SPS Overlay. Here again, the benefitsare a much reduced schedule and a very robust and longlasting solution. Across the full range of applications, thecomposite properties of SPS give rise to a number of othervaluable benefits. In summary, SPS offers:

Simpler, faster fabrication

> Elimination of stiffeners simplifies structures

> Prefabrication and ease of erection shortens and de-risks construction schedules

> Eliminating ‘cropping’ makes SPS Overlay a much faster and less risky method of reinstatement and strengthening

Improved designs and in-service performance

> Less susceptible to fatigue and corrosion, local buckling and the formation and propagation of cracks, compared to conventional stiffened steel structures

> Reduces weight and thickness and allows increased spans compared to conventional reinforced concrete structures

Cost savings and economic benefits

> Reduces build cost

> Reduces construction schedule and risk

> Reduces maintenance cost

> Increases service life

> Increases cargo capacity

> Increases rentable floor area

Enhanced protection and safety

> Greater resistance to accidental or extreme impact loads

> Built-in structural fire protection

> Built-in blast and ballistics protection

> Built-in acoustic insulation

Improved environmental sustainability

> Fully recyclable and reusable gives reduced carbon footprint

> Reduced weight results in less materials, less waste and fewer truck loads

> Faster construction means less disruption and public inconvenienceLifting a pre-assembled triple unit of SPS Terraces

SPS is a structural material used to make the load-bearing plates found in a wide variety of maritime and civil structures. SPS offers benefits in performance, economics, sustainability and safety.

SPS Overlay

SPS Overlay has set a new standard for ship repair and conversion, delivering a faster, less disruptive alternative to traditional ‘crop and replace’ techniques.

SPS Overlay uses existing plating as one side of a steel composite panel formed by a new top plate and an elastomer core. The results fully restore or enhance the strength of the original structure to deliver high impact resistance and permanently flatter surfaces that improve performance and cargo handling.

The benefits of SPS Overlay include:

> Faster repair schedules, minimal labour and reduced downtime

> Non-disruptive, safe, permanent improvements

> Reduced repair costs, lower operating costs and increased revenue potential

Over 270 commercial SPS Overlay projects have been completed. These fall into four categories:

> Offshore vessels and structures including FPSOs and FSOs, drilling rigs, semi-submersibles, and LNGs

> Bulk carriers and tankers including Capesize and Panamax vessels

> RoRos, car carriers, freight and passenger ferries

> A wide variety of other vessels from barges, dredgers and floating pontoons to helidecks and side shell protection

SPS Overlay has been used for extensive deck reinstatement of six Stena Line ferries.

The non-intrusive nature of SPS Overlay contributed to significant schedule savings and ensured the vessels were back in service quickly.

“The original programme of repairing 10,000m² of deck on three ships back to back in 70 days was the most demanding schedule that I have overseen as technical superintendent. The project would not have been possible with conventional repair techniques.”

Wear and tear had resulted in steel diminution to the FPSO Conkouati’s side and bottom shell.

SPS Overlay was used to reinstate the structural strength of the hull. Areas of side shell, which are vulnerable to impact damage from offloading tankers, were strengthened externally, while the bottom shell was strengthened intercostally below the waterline without the need for dry docking.

“SPS Overlay was an obvious choice for us. The repairs were not intrusive and were carried out on-station whilst normal operations continued on board. The equipment used for the job was small and portable and meant that its movement did not cause major inconvenience or involve many people. The work was finished with excellent results.”

IE and DSME (Daewoo Shipbuilding and Marine Engineering Co Ltd) have established a joint venture, SPS Marine Technologies Ltd, to bring SPS into mainstream shipbuilding. The company provides SPS solutions and licences the technology to other shipyards around the world. A wide variety of applications have been developed including hatch covers, vehicle decks, tank tops, bulkheads and hull plating.

Benefits include:

> Simplified more robust structures

> Up to 40% reduction in labour, 50% less welding and 20% less surface area

> Superior in-service performance and reduced through-life maintenance

> Prefabrication guarantees quality and efficiency in construction

Through the MTL partnership, DSME constructs and supplies SPS hatch covers for containerships. The advanced design uses SPS panels to replace the stiffened steel plating of a conventional hatch cover, eliminating all secondary stiffeners and greatly simplifying the structure. SPS hatch covers are functionally identical to the standard steel items, but possess greatly enhanced strength and resistance to impact and puncture from dropped or mishandled containers.

Hatch covers are obvious applications for SPS, not just for containerships, but also for bulk carriers and general cargo vessels. The simplified structure and inherent puncture resistance reduce maintenance costs, enhance lifetime performance and minimise the risk of costly delays due to accidental damage.

SPS Floors formed part of the improvements to Carnegie Hall, which is a 120 year old heritage structure and a New York City landmark. They were used for the renovation of a mezzanine floor in the South Tower and floor additions in the North Tower, which resulted in minimal disruption to the music hall, provision of immediate load capacity on installation and an easy installation in a site restricted area.

For the South Tower, the SPS Floor forms office space that is suspended at mid-height between top and bottom flanges of an existing truss. In the North Tower, the floors add lounge areas to existing rehearsal halls.

SPS Bridge Decks

SPS Bridge Decks are much lighter and less complicated than conventional concrete and steel structures. New construction, replacement and repair can be carried out much faster and with less disruption. SPS Bridge Decks are less vulnerable to fatigue and corrosion and have a longer service life.

Installation of new SPS Bridge Deck

New bridge decks

Prefabricated SPS Bridge Deck panels make new bridges moreeconomic. As an alternative to concrete decks, the 70% lighter,prefabricated SPS Bridge Decks enable shallower, longer, lighterspans to be constructed faster and with less disruption to traffic.As an alternative to orthotropic steel decks SPS Bridge Decksoffer a lighter solution with simple surfaces that are much lessprone to fatigue and corrosion.

Replacement decks

The replacement of old concrete decks with SPS Bridge Deckscan take days rather than weeks and bridges can often remain

operational throughout the procedure. Load restrictions can be removed and extra lanes added without the need for additionalsubstructure.

Deck reinstatement

SPS Overlay is used to reinstate or strengthen steel bridge decks.This process does not require the removal of existing structureand is therefore much faster and less disruptive. SPS Overlayimproves the distribution of wheel loads, decreasing deflectionsand increasing the life of the bridge.

Prefabricated SPS Bridge Deck panels were used to replace concrete panels in four pedestrian bridges across the M6 motorway in England. The installation process required the motorway to be closed for just a few hours overnight, keeping disruption to a minimum.

“The Highways Agency is always on the lookout for new ways to get the job done and SPS is one of them.”

Schönwasserpark BridgeC A S E S T U D Y

The Schönwasserpark Bridge is an orthotropic steel bridge spanning a busy state motorway in Germany. Using SPS Overlay to strengthen the bridge deck ensured the existing structure was retained and additional work on the superstructure was avoided. Disruption to traffic was kept to a minimum and the whole bridge deck was reinstated in just five weeks.

“SPS Overlay technology has proved to be an effective refurbishment measure to make steel deck bridges fit for modern traffic.”

Prof. Dr.-Ing Markus Feldmann, RWTH Aachen University

The Dawson Bridge is a 100 year old, 5 span truss bridge that forms an important link across the North Saskatchewan River running through the centre of Edmonton, Canada. SPS Bridge Decks were selected as the alternative that offered the simplest, quickest installation that minimized truss strengthening and provided another 100 years life for the bridge deck.

“The SPS Bridge Deck allowed the entire project to be completed months faster and millions of dollars less expensively than a traditional concrete deck.”

Tests carried out at the UK MoD’s Defence Evaluation Research Agency (QinetiQ)showed that SPS stops projectiles at shorter strike ranges and higher angles ofattack. SPS reduced risk of penetration by 75% compared with equivalent all steelstructure.

Blast tests carried out at US Navy’s Naval Surface Warfare Center (NSWC)demonstrate how SPS absorbs more blast energy, reduces risk of prematurerupture and limits fragment penetration. The conventional steel panel (left) isruptured by the blast while the SPS panel (right) absorbs the energy and deformswithout rupture.

18

The benefits of using SPS include:

> Lighter, stiffer, simpler structures with improved fatigue and corrosion resistance, more internal space and permanently smooth external surfaces

> Superior blast protection, transferring less energy to supporting structures and reducing risk of rupture

> Increased protection from projectiles at shorter ranges and higher angles of attack

> Built-in fire protection

> Reduced structure-borne noise and vibration signature

> Greater resistance to high energy impacts including groundings, collisions and falling objects

Example applications:

SPS protection can be incorporated into new designs, prefabricated for on-site installation or retrofitted as an SPS Overlay to existing structures.

> New build designs automatically incorporate full range of protection benefits wherever SPS is used as structural material

> Optimised designs where structures have specific requirements, e.g. high point loads on flight decks; reduced vulnerability on amphibious craft

> Retrofitted blast belt applied as additional protection above and below water-line or to provide impact protection for side shells of offshore structures

> Blast walls in refineries or vulnerable public buildings

> Crash decks (during construction) and permanent blast and impact resistant flooring structures

SPS can be used in military and civil applications to reduce vulnerability and to increase survivability and safety. SPS is a lightweight alternative to stiffened plate and reinforced concrete with built-in fire protection and vibration damping as well as energy absorbing properties that enhance the blast, ballistics and impact resistance of structures.

protection and defence

SPS impact test dropping 2 tonne rocks from 3 metres onto a section of SPSdeck. SPS sustained no damage; the all-steel equivalent was destroyed.

SPS Overlay for pontoons of drilling rig is able to absorb impact of 3 tonne drillcollar falling from height of 37 metres without rupture.

Tests carried out at the Danish Institute of Fire Technology (DIFT) show un-insulated steel structure red hot (left) after 60 minutes at 945°C vs. maximum temperature for SPS of 38°C (note the bare feet).

SPS impact test - sharp point-load on a 2 tonne sled striking SPS plate at 5m persecond. SPS sustained minor indentation; the all-steel alternative was punctured through.

Citadel protection is a proven concept that has a successful track record for protecting ships and crew from piracy. The internationally recognized Best Management Practice to Deter Piracy in the Gulf of Aden and off the Coast of Somalia recommends that a “Citadel is designated and lock-down procedures rehearsed to delay access to ship controls and buy time”.

SPS Citadel Access Protection delays and deters entry to the safe refuge. Once installed, the SPS barrier creates a detail free surface that can be rapidly deployed within 2 minutes. When closed, the SPS panels create an extremely strong barrier that can withstand far higher impact loads than equivalent steel structures with superb blast protection against ballistics and shrapnel damage.

sustainability

SPS products offer important benefits in sustainability and thereduction of environmental risk in the construction and shipbuilding industries. These include increased structural efficiency andreduced use of materials and resources in construction. In serviceSPS structures are less vulnerable to damage, require lessmaintenance and have a longer service-life. SPS is easily recycledand, unusually for heavy engineering materials, SPS is easilyreused. This means that SPS structures can also yield lowerthrough-life emissions and a smaller carbon footprint thanconventional concrete and steel structures.

> Potential for 100% reuse or recycling of all SPS materials

> Reduction in other construction materials and resources

> Off-site prefabrication reduces on-site disruption

> Reduced maintenance and increased service-life

> Increased safety and reduced environmental risk

Shipbuilding

SPS can improve sustainability and reduce the environmentalimpact of the construction and operation of ships in several ways. SPS requires less steel, welding and coatings to produce. SPSstructures are less susceptible to fatigue and corrosion therebyincreasing service-life. They are less vulnerable to accidentaland extreme impact events thereby reducing the risk ofenvironmental damage. SPS designs have the potential to allowfor increased cargo volumes, resulting in proportionally fewervessel movements, less fuel consumed and reduced risk.

SPS delivers a more sustainable, long term alternative to conventional steel and concrete when measured against key indicators including environmental, social and economic impact.

The steel and PU components of SPS can be readily recycled into high grade materials

21

Construction

Incorporating SPS in a building can improve its sustainabilityperformance and rating with BREEAM and LEED. SPS Terracesand SPS Floors have been developed for 100% reuse. At the end of a structure’s life SPS Terraces and SPS Floors can bedemounted and, unlike comparable concrete products, canbe reused in new buildings without any additional processing.Alternatively at the end of their life the SPS panels can be recycledinto new SPS and other high grade materials.

An independent study completed by Decarbonize concluded thatreusing SPS can reduce the carbon footprint of a whole buildingby 10-20% compared with using concrete. Using SPS also contributes to:

> 25% reduction in the overall weight of materials used in a structure

> 70% reduction in truck movements

> A reduction in site waste

> Safer on-site working practices resulting in fewer accidents and injuries

Reinstatement and Conversion

In the repair or strengthening of ships and bridges, SPS Overlayincorporates – rather than cutting out and replacing – the existingstructure, thereby reducing the quantity of new steel used byup to 75%. The process uses much less welding and is much less labour intensive in what are typically hazardous conditions. SPS Overlay requires a fraction of the time needed for conventional repairs and, in the case of bridges, can be completed with onlypartial closure, thereby substantially reducing the disruption to traffic.

Ongoing initiatives

IE continues to explore opportunities to further develop thesustainability benefits of SPS, including:

> Minimizing the full life emissions of a building

> Working with architects and engineers to design structures that capitalise on the potential to reuse SPS products

> Working with suppliers to maximize the recycled content in all SPS products and applications

SPS Floor panels are bolted into position and can be as easily unbolted for reuse at the end of a structure’s life

Building with SPS can reduce truck movements by 70%
