Offshore Technology Yearbook

2O18

Siemens Gamesa puts the power in your hands. The new SG 8.0-167 DD, with its B81 blades, allows for an 18 % greater swept area and up to 20 % higher annual energy production than the SG-7.0 offshore direct drive turbine.

As part of the proven offshore direct drive platform, the SG 8.0-167 DD utilizes known technology, combined with its rotor upgrade, to offer customers reliable revenue streams with reduced cost of energy and mitigated risk. This is how we turn more than 25 years of offshore experience into customer value.

Turning experience into customer value: Greater rotor for greater benefit

The heavy hitters of the offshore turbine world are inching towards

10MW territory as part of a journey expected to result in hardware rated at 13MW to 15MW before the middle of the next decade.

Siemens Gamesa and MHI Vestas are dominating the market with top-tier offerings designed to produce maximum returns from projects being built both in the increasingly subsidy-free northern European sector and emerging nations.

The Danish manufacturer’s V164-9.5MW machine, which only reached prototype stage last year, has already been lined up for nine projects including Parkwind’s 224MW Northwester 2 off Belgium as soon as next year.

Other conditional or preferred orders include EDPR’s 950MW Moray East off Scotland and Innogy’s 860MW Triton Knoll off England while the turbine is also expected to feature off the Netherlands and Taiwan.

Siemens Gamesa took the wraps off its 8.0-167 model late last year. The German-Spanish company said at the time the 167-metre rotor would provide “even higher energy yields at lower wind speeds”.

Orders have already been lined up for 11 wind farms, starting in 2020 with delivery to Orsted’s 752MW Borssele 1&2 off the Netherlands and Otary’s 266MW Mermaid and 246MW Seastar off Belgium. Further supply deals will follow off Denmark, France and Taiwan.

The manufacturer has already produced initial B82 blades for the prototype and is at an advanced stage with fabrication of the tower, nacelle, generator and hub.

The first iteration will go up onshore in autumn at the Osterild test site in Denmark.

Industry observers said they expect both the 8.0-167and V164 offerings to ramp up nameplate capacity following initial operational experiences, further fine-tuning of control systems and site-specific assessments.

An unnamed manufacturer is already discussing deployment of a 10MW-plus prototype turbine at an offshore wind port facility in Rotterdam from end-2019, although it is unclear whether that will be targeted for eventual use onshore or off.

Rival manufacturers continue to offer 6MW-class hardware while looking to make a quantum leap to 10MW-plus machines without the intermediate steps taken by the current market leaders.

GE aims to have its Haliade-X 12MW prototype installed at a European site in mid-2019. The direct-drive machine will feature blades of 107 metres and include power electronics in the nacelle to minimise the amount of offshore commissioning.

Certification is expected in mid-2020 followed by serial production the same year with deployment due in 2021.

Senvion is leading the 14-strong ReaLCoE consortium in pursuit of a long-mooted turbine of more than 10MW. A pre-series offshore array is planned for 2021 to validate the concept, which itself will build on a “successful prototype operation” due at an unspecified date in the next few years.

One long-time independent developer of large-scale offshore turbines said it is encouraging to see lessons learned across the industry being put into practice at actual projects.

“It is satisfying to see the market catching up with the work done by some of the

pioneers into 10MW-plus technology over the last 10 years,” he said.

China still plays host to a dizzying array of turbine technologies, many previously adapted from onshore machines but increasingly with an offshore-only focus designed specifically for lower wind speeds.

CSIC Haizhuang installed its H151-5.0MW technology last year at Huaneng Rudong and was poised to supply two units to the struggling Dounreay Tri floating demo off Scotland. Envision has a range of turbines for its home market but will have high hopes for the success of its top-tier 136/4.2MW machine.

Goldwind continues to offer its 3MW turbine ahead of planned installation of a prototype for its GW6.X platform this year. The latter will feature 6.45MW and 6.7MW iterations and blades ranging between 154 metres and 171 metres.

Ming Yang is installing 3MW and 6MW models produced under licence from German technology developer Aerodyn Engineering while also developing an in-house 6.5MW model, although details of the latter from what is no longer a listed company are few and far between.

Shanghai Electric last year extended a long-standing licence deal with Siemens Gamesa and will produce a local version of the new 8.0-167 turbine. The expanded Sewind line-up is likely to remain one of the most popular platforms off mainland China.

The nascent US market is so far content to look to Europe for turbine supply but, as happened with its onshore wind sector, calls for local content will become impossible to ignore should the country’s multi-gigawatt ambitions become a reality. n

Market leaders break from the pack with 8MW and 9.5MW models heading for the water

in next two years, writes Todd Westbrook

Key characteristicsTwo-bladed downwind turbine designed for a 40-year service life with ‘an integral plant approach’. The design has two nacelle levels, a passive cooler platform, a self-aligning ‘soft yaw’ system, and a lattice-type welded truss tower. The latter ‘open’ structure extends from the seabed to the nacelle yaw bearing.

Product notes1. 6.2MW configuration with potential 12MW machine also proposed.2. Modular platform design aimed at rapid upscaling in line with market demand.3. ‘Soft yaw’ capability means the rotor follows wind direction changes automatically

in normal operating mode, and then only requires some nacelle yaw dampening motion. In emergency situations, like a combination of extreme weather and/or turbine failure, eight yaw motors are activated for bringing the turbine into a safe non-operating position. The extra ninth motor provides system redundancy.

4. Small MV transformer connects the modular converter and other power consumers.

Drive train

Key characteristicsLightweight upwind medium-speed geared wind turbine. Radical concept including ship-hull type nacelle structure, active-yaw control, and elastic hub teeter hinge.

Product notes1. Builds on experience with 1.5MW Gamma research turbine (1991-97).2. Two-bladed turbines dynamically unbalanced, providing major design challenges.

One measure to minimise high structural (bending) loads in particular during yawing by a flexible structure with limited pivoting capability called teeter hub.

3. Very high rated tip speed of 131.9 m/s (common 80-90 m/s).4. 160m rotor enlargement for bottom-fixed solution considered.5. Drive train has four-point gearbox support (main shaft and two rotor bearings),

two-stage planetary gearbox and brushless induction generator. Each gear stage housing can be split horizontally and vertically for easy component exchange and in-board repairs. Gear coupling prevents rotor-induced bending moments entering the gearbox.

6. Initial floating model planned for site off Norway; 10MW-plus model reported to be under development.

Key characteristicsAdvanced medium-speed geared turbine model that built on the initial pioneering Gamesa G128-4.5MW turbine, which appeared as a prototype in 2008. The innovative drive train technology was jointly developed with ZF Wind Power, formerly Hansen Transmissions. The 5MW successor models for both onshore and offshore were an in-house optimisation of the 4.5MW G128-4.5MW. Offshore versions were only available with single-piece rotor blades.

Product notes1. G132-5.0MW offshore model renamed

Adwen AD 5-132; this model was also available with a 128-metre rotor diameter.

2. Suitable for placement on monopile-type support structure due to favourable head mass despite its power rating and rotor size.

3. Cast housing contains main shaft and two rotor bearing, and is flanged to a two-stage planetary gearbox and PMG; flexible coupling in between gearbox and PMG.

4. Adwen product line discontinued in wake of Siemens-Gamesa merger.

Key characteristicsAdvanced medium-speed geared drive train concept builds especially on the pioneering Gamesa G128-4.5MW turbine and drive technology, and 5MW successor models for both onshore and offshore; record 88m long blades with carbon.

Product notes1. Adwen product line discontinued following merger of Siemens and Gamesa2. Initial Areva 8MW drive train concept up-scaling of low-speed 5MW Multibrid technology.3. Adwen 8-180 had one of offshore wind’s lowest specific power ratings.4. Cast housing contains main shaft and two rotor bearings, and is flanged to a two-stage planetary gearbox and PMG; flexible coupling in between gearbox and PMG; main shaft, gearbox and generator independently exchangeable in the field.5.

Key characteristicsWind Power Ltd’s unusual two-bladed VAWT Darrieus-type aerodynamic lift turbine featured V-shape rotor and double blade tip winglet for stabilising functionality at each blade tip. Initial layout with equally interspaced rigid sails along the component axis. Triangular shaped rotor swept area. Company declared insolvent in 2017 and liquidated with no takers for related intellectual property.

Product notes1. Can capture wind from all directions eliminating yaw system. Blades

do not rise and fall against gravity like with HAWT.2. Modest swept area for 10MW, plus maximum aerodynamic efficiency disadvantage for large VAWT’s in 38% range versus >45% for HAWT.3. The rotor turns at about 3 rpm compared to 9-10 rpm for three-bladed HAWTs with 185-190m rotor diameter; higher torque input level

by a factor of three requires heavier, more expensive high-torque drive train.4. No actual tower. Rotor central mounting at fixed or floating support structure also incorporating the drive system and power conversion

technology.5. Long-term objective was 1GW offshore in UK by 2020.

Key characteristicsInitial C-150 concept built on the pioneering 2.5MW Clipper Liberty design featuring a two-stage semi-integrated distributed high-speed drive train with four flanged PMGs.

Product notes1. If it had succeeded the C-150 would have represented a technological benchmark in

terms of head mass reduction.2. 150-metre rotor diameter is today considered small for 10MW offshore turbines.3. An unusual C-150 feature was the high rated generator speed in the 2270 rpm range

compared to the Liberty’s wind industry compliant 1133 rpm.4. The final Britannia drive system design was again semi-integrated but now medium-

speed geared with a two-stage planetary gearbox and single PMG.5. Clipper revealed plans for a patented retractable rotor diameter technology, the

largest diameter for maximum energy capture at low and medium wind speeds and the smallest for limiting high-wind loads. This was never realised.

Key characteristicsClassic pioneering mechanical/electrical design with distinct egg-beater shape nacelle. The initial 1.5MW E-66 prototype with 66-metre rotor diameter was installed in late 1995.

Product notes1. Evolutionary upgrade and upscaling of early ‘super class’ 1.5MW E-66 turbine,

followed by a 1.8MW upgrade, and final 2MW model version. Successor sister models with enhanced 70-metre rotor diameter.

2. Substantial onshore track record at high-wind coastal sites. 3. One key envisaged offshore modification highlighted by company founder Aloys

Wobben was a fully enclosed aluminium nacelle cover for enhanced heat exchange and generator temperature management via natural airflow over the nacelle.

4. A parallel development goal was protection of the ‘open’ generator by effectively sealing it off against the harsh marine environment.

5. Planned high-wind 86.4MW Lillgrund project in Swedish shallow water, to comprise 48 turbines and construction start envisaged for 2001, canned.

Key characteristicsWorld’s first 4.5MW to 5MW ‘super class’ turbine. Pioneering mechanical/electrical design with egg-beater shaped nacelle and huge 12m diameter ‘disk-shape’ ring generator.

Product notes1. Rotor diameter enlarged to 114m following construction of second prototype.2. E-112 power rating raised from 4.5MW to 6MW in 2005.3. Ongoing discussion on the suitability of E-112 for offshore due to the ‘open

generator’ and rather high head mass. 3. Building a huge 12m generator capable of retaining a modest air gap while exposed

to continuously changing combinations of electrical, mechanical and thermal loads is widely considered a remarkable technological achievement.

4. Succeeded by 6MW E-126 (2007) and 7.5MW E-126 (2010).5. Electrically excited air-cooled Enercon synchronous generator; four 90-degree stator

segments represent electrically four individual generators, and two 180-degree rotor segments.

Product notes1. GE overall strategy focused on design for reliability (the turbine should not trip) and

minimising offshore activities plus costs of installation equipment2. Product-design focus on rotor blades, advanced controls and grid integration.3. Drive train layout aimed at ensuring that only “pure” rotor torque loads enter the

generator, thereby offering a major reliability enhancing benefit.4. Unusual direct drive solution with rear mounted inner-rotor PMG. The generator

is electrically split into two 50-50 sections, whereby each section feeds power to a separate power converter offering redundancy and increased availability. Rotor and generator interconnected by a long hollow main shaft supported by two main bearings; extra bearing set for the generator stator necessary with this layout.

Key characteristicsBased on Fuji Heavy Industries’ Sabaru 80-2.0 model, Hitachi used a 100kW Sabaru 22/100 for quantitative upwind/downwind configuration comparison. Conventional mechanical/electrical turbine design incorporates active-yaw system but can yaw freely during high wind storm conditions.

Product notes1. Hitachi modified the 2MW HTW2.0-80 design for meeting the additional demands

caused by the movements of a semisub floater structure.2. Tower design had to be modified for coping with the higher static and fatigue-

related loads due to the swaying movements.3. The tower diameter top section simultaneously has to be kept as narrow as possible

for minimising wind shadowing impact at the downwind rotor.4. 3-point gearbox support (main shaft and single main bearing) and 4-pole DFIG.5. Developed for operation at typhoon-prone and high-turbulence mountainous

regions and on floating offshore platforms.

Key characteristicsUnusual two-bladed fixed-speed turbine design with teeter hub; single-piece central inner section with fixed pitch angle and pitchable 10-metre blade outer sections.

Product notes1. Two-bladed design.2. Initially designed for stall power output limitation. 3. Rotor concept design and manufacture by former Dutch

supplier Polymarin.4. Rotor attachment to the main shaft by means of one huge metal clamping ‘belt’ proved an effective but costly solution.5. Integration of pitch bearings inside main central rotor blade structure with metal castings and two external cardan shafts for activating

the mechanical-hydraulic pitch mechanism proved costly and required complex engineering solutions.6. Rather small rotor size even for early wind industry period.7. HMZ WindMaster filed for bankruptcy in February 1996. 8. Company IP and product inheritance rights split between WindMaster Nederland and Turbowinds company established by six former

HMZ Windmaster employees.

Key characteristicsUnusual direct drive stall downwind concept with fibre-reinforced composite rotor manufactured in one piece without seams or joints. The total integrated blade mass is 58 tonnes with the generator to a large degree integrated within the rotor central part. The turbine features a helicopter landing platform.

Product notes1. Design focus at optimal robustness through minimising number of components in

rotor, generator and support structure.2. Additional main focus on the control and monitoring at wind farm level instead of

turbine level for achieving the desired reliability and availability improvements.3. Open lattice type truss tower extends up from seabed.4. Patent application for integral hollow composite rotor (hub design with elastic rotor)

hub interface, hub integrated generator and active rotor speed control.5. Initially envisaged 10% market share of total 60GW planned by 2020 in Europe.6. Rotor-speed control system aimed at enabling a constant output level from rated

wind speed up until cut-out.

Key characteristicsLightweight multi-rotor concept with three-legged lattice-type central tower; the two horizontal levels each incorporate two turbines, supplemented by one upper central turbine mounting; rigid turbine mounting with individual yaw systems skipped; collective yaw system at tower base.

Product notes1. Early multi-rotor turbine concepts originate at least from the 1920s but still very

limited track record.2. Multi-rotor turbines can benefit from multiplier effect but contain more components

while turbine dynamics complexity is far greater.3. Germany’s Saarbrücken University of Applied Sciences Innowind wind research

group headed by emeritus professor Friedrich Klinger presented feasibility study results in 2012 containing detailed comparative calculations with single-rotor turbines, various structural principles and layouts. Technical solutions include a four-turbine 12MW design.

Key characteristicsPatented multi-rotor turbine concept with semi-vertical central rotor arms mounting, central housing support and integrated yaw system. Three rotors mounted at rotor arms equally interspaced at 120-degrees in the rotor plane. During normal operation one rotor arm points up vertically. In the event of single rotor failure, the unit is brought in stationary bottom position. The remaining rotors now turned in upward position at 120-degree interspacing continue operation at a maximum 67% of cumulative rated power (6MW). Integral support structure and tower design. Donor nacelles must be technically adapted before incorporation in MWT-6000 structure.

Product notes1. Multi-rotor turbines can benefit from multiplier effect, and therefore scale faster

than single-rotor turbine developments, i.e. 2 x 3MW = 6MW; 3 x 4MW = 12MW.2. Multi-rotor turbines also contain more components and the turbine dynamics more

complex compared with single rotor systems of similar capacity.3. One 300kW turbine with four 75kW rotors built in the Netherlands operated for

many years successfully.4. Vestas installed a 900kW concept turbine, again with four rotors, in 2016

Key characteristicsUpgrade and up-scaling of the initial 1.5MW stall regulated Nordtank NTK1500/60 turbine commissioned in August 1995. Features the classic non-integrated mechanical drive train design popular with many competitors. Jacob Jensen Design drew elegant lines of the nacelle and tower and received the German IF Award and Red Dot Award for Product Design in 1997. The nacelle shape was retained for the NM2000/72.

Product notes1. The NTK60/1500 and largely comparable NM 2000/72 nacelles were heavy and

expensive to produce due to the characteristic steel ‘bathtub’ shaped nacelle and being the main load-carrying structure.

2. Onshore prototype was installed at a high-wind site with average speeds of 11.5m/s at Burgar Hill in the Orkney Islands in 2000.

3. Yttre Stengrund wind farm in Sweden removed in late 2015 with apparently only one unit still operating due to difficulties in finding replacement components. Initial plan to repower the site with larger turbines and reuse of monopile foundations was scrapped.

Key characteristicsThe G4 platform is an evolutionary development and redesign of the SWT-3.6-120, and includes the SWT-4.0-130 flagship sister model. The SWT-4.0-120 features a smaller 120m rotor diameter and the slender 58.5m B58 blades of the SWT-3.6-120. Reduced rotor size makes SWT-4.0 120 suitable for sites with tip height restrictions, and might allow an easier switch from the SWT-3.6-120 while retaining original permits. Uses blades manufactured with in-house IntegralBlade technology.

Product notes1. The SWT-4.0-120 offers higher AEP and reduced LCOE compared to its predecessor

offshore ‘workhorses’.2. Four-point gearbox support (main shaft and two main bearings), new compact

three-stage gearbox with higher torque rating, IG.3. The SWT-4.0-120 has been licensed to Shanghai Electric.

Key characteristicsStriking radical direct drive design with open 25m spoke-type generator. Integration with three rotor blade supports eliminates need for separate rotor hub. Rated tip speed 103m/s.

Product notes1. The three pitch bearings positioned 15m off rotor centre, allowing direct coupling

between blades, blade support structures and generator offering a short load path. Design feature further leaves generator air gap unaffected by flapping (forward and backward) wind loads. Rotor torque and blade gravity loads in rotor plane distributed and absorbed by the entire structure.

2. Blade support structures solution enables shorter and lighter blades.3. Main components inspected/exchanged by using inboard crane and a work platform fixed to the tower, plus specially developed

inspection baskets and professional climbers. Exchange generator segments up to 10m/s wind speeds.4. Blade and large bearing exchange requires crane vessels.5. Prototype head mass determined at 625T but is expected to reduce by replacing steel blade support structures with composite material.6.

Offshore Wind Turbine Generators.

Instead of lifting capacity, hook height is

the governing factor behind this design.

By allowing for hook heights of up to

160m above deck level, with lifting

capacities ranging from 90-600mt,

Huisman designed a dedicated, super-

Key characteristicsThe WinWinD 1MW WWD-1 (2001) and WWD-3 models are based on Multibrid ‘hybrid’ drive technology, developed and patented by German engineering consultancy Aerodyn Energiesysteme in 1996-97. The ground-breaking Multibrid technology was aimed at combining reliability of direct drive with compactness of high-speed geared. Multibrid-type turbines are claimed to be cheaper to produce than direct drive and more reliable against high-speed geared.

Product notes1. WinWinD was founded in 2000 and the

same year acquired a Multibrid licence for turbine technology up to 3MW.

2. Also in 2000, Pfleiderer of Germany acquired exclusive rights to use Multibrid technology in applications over 3MW. Pfleiderer Wind Energy built a 5MW prototype during the course of 2003.

3. Rotor hub connected directly to the machine casting by means of a single large-diameter taper roller bearing.

Key characteristicsInnovative compact direct drive concept with few moving parts, including single rotor bearing and front-mounted generator. The hollow bearing and generator support structure enable easy service access to the hub. An airtight nacelle with ‘over’ pressure prevents saline air entering. The turbine was to be initially offered in 1.5MW (3kV) for onshore and faster spinning 2MW (4kV) version for strong-wind (offshore) conditions without noise restrictions.

Product notes1. An evolution of the 2MW model and now

major XEMC Windpower volume product with expanded rotor diameter range.

2. Introduced during 2000 by Zephyros consortium led by Lagerwey the Windmaster, ABB, Mammoet, rotor blade supplier Polymarin, control specialist Prolion and mechanical engineer WWT.

3. Lagerwey the Windmaster filed for bankruptcy in 2003; Zephyros became independent but filed for bankruptcy in 2005. New owner Harakosan of Japan concentrated on further development of Zephyros-based onshore turbines.

FLOATING CONCEPTSBackers of a handful

of pilot projects are preparing to test the

technical and commercial viability of a variety of floating wind concepts in a bid to join the industry’s vanguard.

Installed capacity is expected by optimists in the sector to reach at least 200MW worldwide by 2021, which would be a fourfold increase on current levels.

French floating developer Ideol installed its 2MW Floatgen project in May at the SEM-REV test site off Le Croisic, western France.

The square-outlined, surface-level Ideol Floating Pool platform will also feature in the 3MW Kitakyushu demonstration project in Japan co-developed with Hitachi Zosen and due online by early 2019.

Principle Power’s WindFloat

concept is scheduled to be installed at the three-unit, 25MW WindFloat Atlantic off Portugal next year.

California outfit Principle has also been lined up to supply seven of its WindFloat platforms for ACS’s up to 50MW Kincardine wind farm off Scotland, which is scheduled to go live come 2020.

The Ideol and Principle Power technologies have again been earmarked for four-unit arrays of around 24MW to go online off France in the early 2020s.

The 30MW Hywind Scotland project installed last year by Equinor (the former Statoil) in the Buchan Deep around 30km off Peterhead currently has the commercial field to itself.

Hywind UK commercial lead Elisabeth Stenersen said the

company’s floating device, featuring a pitch controller that dampens excessive motion, has operated “without any major problems”.

The capacity factor at the site, which features five Siemens Gamesa 6.0-154 turbines atop spar floaters, has topped 65%.

Stenersen said Equinor, which aims to spend up to 20% of total capex through to 2030 on clean energy, sees “vast potential” for floating wind.

The Norwegian company added that Scotland, France, Ireland, the US and Japan hold the most promise in the near-term.

Equinor is also exploring island locations and examining its portfolio of oil and gas platforms for potential floating wind development. Stenersen

said she is aware floating wind needs to close the costs gap with fixed offshore but believes this can be achieved with standardisation, optimised design of substructures with reduced prices per tonne and development of local supply chains.

“We think we can get down to €40 to €60 per megawatt-hour by 2030,” she said. “We are looking at using concrete for the hull, which would give us flexibility to increase the draft while having shallower depths,” she added.

Major industrials such as Naval Energies, a subsidiary of French state-owned shipbuilder Naval Group, are also getting in on the act.

The company is co-developing with Vinci a next-generation concrete/steel hybrid semi-submersible

system under the Sea Reed programme supported by ADEME, the French Environment and Energy Management Agency.

The foundation will feature in the 24MW Groix & Belle-Ile pilot project off Brittany developed by Eolfi and CGN Europe.

Naval Energies UK development manager Robert East said the company is positioning itself as a provider running the gamut of design, fabrication, moorings, anchors, cabling and maintenance for floating wind technology.

“Floating structures are going to change fundamentally where offshore wind projects can go. It is potentially an enormous market with huge geographical diversity,” he said. n

Upcoming projects to test waters as developers seek to close the costs gap with fixed offshore and unlock potentially enormous market, writes Tim Probert

Product notes1. The Eolink concept combines a turbine with light floating structure with a

single point mooring. A set of profiled arms supports the structure, instead of a conventional single tower to simplify installation and maintenance because power cables and mooring lines are installed independently from the wind turbines.

2. French developer Eolink undertook tank testing of a 1:50 scale model at IFREMER facilities in Brest in 2016.

3. A 1:10 scale prototype of a proposed 12MW floating offshore wind turbine was installed in April 2018 off Sainte Anne du Portzic in Brittany. The device measures seven metres long, six metres wide and has blades that rise 22 metres above the sea.

Key characteristicsThe Eolink concept replaces the classic mast by three arms and is supported on a trellis, which helps to distribute the weight of the structure and thus improve resistance to fatigue. Due to its rigidity, the architecture also eliminates the problems of vibrations inherent in the mast. The structure also allows increasing wind turbine size.

Product notes1. Adapted modular tension leg platform developed by SBM Offshore of the

Netherlands. Advanced stage of development.2. Inclined taut mooring configuration creates fixed meeting point just above nacelle

resulting in very low nacelle motions/accelerations, which reduces loads on turbine and tower. Also allowing catenary instead of ‘lazy wave’ configuration for the electricity cables.

3. Minimised cable tensioning during normal operation and extreme conditions allows classic, and inexpensive, mooring solutions.

4. Small seabed footprint and no active systems. ‘Fully self-stable’ during towing (with or without installed turbine) and installation with simple tugs.

5. Low floater mass (typically below 200T/MW). No need for dry-dock.

2. Founded in 2008, small-scale tank testing in 2012 then DECC ‘six-figure’ grant in following year financed further tank testing and prototype development. Ready to launch offshore prototype.

3. Three distinct measures prevent heavy response resulting from low mass when exposed to severe wind and wave events. Buoyancy element spread over wide area, which reduces pitching accelerations.

4. Uses minimal water plane area (water surface displaced by buoyant elements). Conical heave-plates for ‘wide grip’ on seawater deployed to add both mass and damping.

Key characteristicsTetraFloat lattice-type structure yaws bodily over the water. Power transmitted through single central mooring point using rotating transformer also mechanical stay. Low structural mass due to favourable loading. Donor turbine yaw system not required. Floater can be equipped with facility to lower turbine using same structural frame “at virtually zero added cost”.

Installation vessel operators are trying to ride out near-term choppy waters in the

offshore wind construction market in the hope they can position themselves for plain sailing through the post-2020 pipeline.

The double whammy of short-term work shortages and rock-bottom contract rates for the few jobs up for grabs is causing headaches for vessel companies across the board.

Many are struggling to keep fleets busy as larger vessels and turnkey contractors have taken most of the plum installation jobs due to get underway in the next few years.

Operations and maintenance work is one avenue being explored by some companies keen to put their vessels to work.

Although O&M prices are a fraction of those for installation jobs, keeping vessels in operation, even if only just breaking even, is preferred by many to laying up, said sources.

Several vessel operators are also offering their jack-ups for construction-support jobs, such as offshore substation commissioning and accommodation.

Dayrates here are said to have fallen by well over 50% compared with levels in recent years.

Other companies are mulling jack-up missions to Asia and other emerging markets while any upturn in oil and gas could also appear attractive.

Sources describe a two-tier market where all but the largest jack-ups have mostly blank diaries in the coming years.

GeoSea installation vessel Innovation, Jan De Nul’s Vole Au Vent, Van Oord jack-up Aeolus and Seajacks Scylla are among the most sought-

after installation ships, said sources.

All four, along with Seafox 5 and Swire Blue Ocean sister vessels Pacific Osprey and Pacific Orca, are set for busy construction campaigns through to 2020.

There is the potential for opportunities in the short-term in the shape of sub-contracts from turnkey operators that need the extra muscle to relieve packed schedules. Operators are otherwise looking to the future.

Multi-gigawatt pipelines in the major European markets of the UK, Germany and the Netherlands mean construction know-how will be in demand between 2020 to 2025 and beyond.

There is also new capacity due to be built in Belgium, France, Denmark and possibly in emerging markets such as Poland and other Baltic states.

Vessel operators are, however, grappling with the challenge of handling next-generation turbines and larger foundations, which are due to become the norm post-2020.

Several executives said they remain in the dark about how the current fleet of jack-ups will fare with 12MW-plus turbines as plans for the latter remain largely under wraps.

Extensive facelifts may be required to handle the larger equipment.

Many jack-ups have already undergone upgrades, including beefed-up main cranes, to tackle the current fleet of 8MW-plus turbines and foundations but few operators will place bets on what the future holds.

Meanwhile, several new installation vessels are due to hit the market in the coming years. Belgian contractor GeoSea will shortly take delivery of jack-up Apollo, which is

expected to be deployed on both turbine and foundation installation duties starting later this year in Europe.

Dutch company Jumbo Maritime has ordered a heavylift vessel that could service the renewables sector once it hits the waves in 2020.The Ulstein-designed newbuild will have a 2500-tonne lifting capacity, it is understood.

Compatriot OOS Energy is planning two jack-ups, one of which is called Luctor et Emergo and could start work in the offshore wind sector in late 2020.

In the US, New Orleans marine designer AK Suda is planning a new purpose-built jack-up for the US offshore wind sector. The so-called JG10000 is due to be available for charter in mid-2021.

US lifeboat management company All Coast will own and operate the Jones Act-compliant vessel, which will be able to handle the latest class of 8MW-plus turbines.

Boskalis crane vessel Bokalift 1 has meanwhile already made its debut. The 216-metre ship is working under sub-contract to Van Oord on a maiden foundation installation job at the 714MW East Anglia 1 wind farm off the UK.

Oil and gas market vessel operators are looking

to make significant inroads in the offshore wind market.

Italian company Saipem is chasing balance of plant jobs in several markets on the back of installing substations for Orsted’s 1.2GW Hornsea 1 wind farm off east England. The campaign is due to wrap up this year.

Heerema Marine Contractors, another mainly oil and gas player, is planning to deploy its Thialf and Aegir construction vessels more regularly in offshore wind. n

Work shortages and tight contract rates creating perfect storm for all but largest jack-ups but

multi-gigawatt construction pipelines should lift clouds post-2020, writes Stephen Dunne

CABLE-LAY VESSELSCable-lay vessel

operators are fighting it out to land plum

installation contracts at upcoming wind projects in Europe while the growing operations and maintenance market is increasingly seen as a battleground where valuable spoils are at stake.

The largest pre-2021 export and array installation contracts up for grabs are for campaigns in German, Dutch and Belgian waters.

Farther down the line, competition is likely to be fierce as several state-of-the-art installation vessels are due to enter the market over the next few years.

The first to arrive will be DEME subsidiary Tideway’s Living Stone, which is widely tipped for a debut installation gig later this year on export cables at Orsted’s 1.2GW

Hornsea 1 wind farm off the UK east coast.

Nexans of France has begun work on its latest offering at the Uljanik shipyard in Croatia. The vessel, yet to be named, is scheduled to commence operations in late 2020.

Norwegian shipbuilder Vard has meanwhile started fabricating a new deep-water installation vessel for Prysmian, which the Italian company hopes to use for campaigns from late 2020.

Danish wire manufacturer NKT added cable-lay vessel Victoria to its stable last year. The ship will install NKT-made export lines for Innogy’s 860MW Triton Knoll and for the EDPR-led 950MW Moray 1, both in the UK.

“Top-end vessels need to be able to carry huge payloads and have the deck

space to accommodate the equipment required to support the latest generation of ROVs used for cutting and jetting operations,” said Ian Douglas, chief executive of UK-based cable installation outfit Global Marine.

Recently built and under-construction vessels tend to feature twin cable baskets. A double carousel will place operators in pole position to land jobs installing the twin single-core HVDC cables, which are tipped to feature at some future offshore projects.

“The efficiency and speed at which state-of-the-art vessels can install means they can stay competitive amid the downward price pressure from the push towards zero-subsidy projects,” said Douglas.

Marine contractors are also looking to squeeze the most

out of their older vessels by mining the increasingly rich seam of cable O&M.

Installed cables face numerous legacy issues, representing a potent opportunity for vessel operators.

“Installers are looking to strike cable O&M framework agreements with wind farm operators as a way of making the most of any spare capacity in their fleet,” Douglas added.

Operators will also likely dispatch ageing assets to the US and Asia for future installation contracts.

Projects in emerging markets tend to be in shallower waters and cover smaller areas than future work in Europe, offering a suitable swansong for some vessels.

Further consolidation in the

offshore cable installation and subsea market is expected over the next year as developers increasingly look for turnkey support.

Engineering, procurement, installation and construction contracts require companies with large balance sheets, diverse fleets and substantial in-house project expertise.

This has forced installation companies into the market to acquire new assets and beef up offerings.

In the last 12 months Global Marine has acquired Fugro’s cable-lay assets while Subsea 7 swooped for array cable specialist Siem Offshore Contractors.

Companies with ambitions to offer full-scope contracts are also looking to add seabed preparation, ROV specialists and survey nous to their stables, sources said. n

Export and array cable installation contracts in the European market will be hotly contested by the existing fleet and new state-of-the-art vessels while O&M is offering

additional revenue streams, writes Patrick Browne

S Post-2020 picture looks rosy in Europe and beyond but cost challenges and downtime continue to exert

pressure in the interim, writes Stephen Dunne

Offshore wind fabrication yards are on full procurement alert as

they look to secure post-2020 supply deals on wind farms in Europe and farther afield.

Recent capacity auctions in the UK, Germany, the Netherlands and Taiwan, as well as positive moves in markets such as Belgium and the US, mean there is a well-stocked pipeline of steelwork projects.

Yard executives are almost unanimously bullish about the potential to score plum fabrication deals in what promises to be a busy 2020-25 build-out period globally.

Although some of the next decade’s fabrication work has been placed already, including Sif and Smulders’ monopile and transition piece deal at Innogy’s 860MW Triton Knoll in the UK, much treasure is still to be plundered.

In the UK, balance-of-plant contractor GeoSea is in the market for the supply of 100 turbine jackets for the EDPR-led 950MW Moray East wind farm off Scotland, due online in 2022. Procurement is expected to come to a head by the year-end.

French utility EDF is also expected to bring a 54-jacket supply deal to market shortly for its recently acquired 450MW Neart na Gaoithe development off Scotland, set to go online in 2023.

In Germany, fabrication deals for virtually every one of the 10 auction-winning wind farms that secured a total of 3.1GW of capacity in rounds this year and last have either hit the market or will do so soon. A steady stream

of Dutch auction-winning sites and as-yet-unconfirmed post-2020 zones in Belgium and Denmark will also add to the mix.

Meanwhile, there are moves afoot in undeveloped offshore wind markets such as Ireland and Poland to line up routes to market for wind farms to come online between 2020 and 2025.

In addition, fabrication players are looking farther afield to establish themselves in nascent markets primed for take-off.

Taiwan has awarded 3.8GW of capacity to 12 projects, all set to come online before 2025, with several European fabricators eyeing local partnerships to supply foundations.

A similar picture is developing in the US where a multi-gigawatt pipeline of eastern-seaboard sites is aiming for pre-2025 commissioning.

After years of relatively slim pickings, the level of work coming onto market is building optimism and the belief that experienced offshore wind fabrication yards are on the brink of a significant and long-term ramp-up of activity.

However, ther are several challenges facing those hungry for a slice of the action.

Fabrication yards across Europe are under intense pressure to cut costs in delivering on existing contracts and securing new work for clients keen to squeeze every last drop of value from the supply chain.

Offshore wind is now firmly

in the era of low levelised energy cost and, according to sources, the absence of true innovation and industrialisation is further shifting the onus to trim budgets over to the supply side.

Steel manufacturers are also having to juggle yard downtime in the short term before the predicted post-2020 bonanza gets underway.

Some yards, with no confirmed work over the next couple of years, are facing significant difficulties in keeping operations ticking over until work cranks into gear on any newly secured contracts.

Although the potential of picking up sub-contracts at short notice is still possible — Steelwind Nordenham, for example, recently scored a 32-monopile supply deal from Dutch outfit Sif for the 203MW Borkum West 2.2 after the latter farmed out the job — few substantial pre-2020 deals remain up for grabs at the moment.

Fabricators are also reporting ever-narrowing timelines that make delivery of large numbers of foundations possible for none but the largest players.

Smaller yards are pivoting to try to add value by offering to carry out smaller chunks of work, such as assembly or outfitting, in an effort to ensure the coming glut of contracts brings some reward.

Meanwhile, the spectre of new market entrants based in low-cost economies, mainly in Asia, continues to loom large over contenders. n
