FSRU Toscana A History in the Making
60th SIGTTO Panel Meeting 8th - 9th October 2014 Giovanni Giorgi OLT Operations Manager

The Project from dream to reality
Conversion of the LNG carrier 'Golar Frost' H1444 into a Floating Storage Regasification Terminal FSRU Toscana moored 12 nmiles from the Italian coast between Livorno and Pisa, in sea depth of 120 meters, connected to the national gas grid through a pipeline of 36.5 km, built and operated by Snam Rete Gas
The Authorization process and the Conceptual/Feasibility studies started on 2002
EPCIC Contract awarded March 2008, Golar Frost purchased June 2008, conversion started June 2009 in DDW (Dubai)
Terminal arrived offshore Livorno July 2013, 4 StS Cargo Transfers done during Commissioning and has been fully operational since 20th December 2013

Why Offshore LNG Regas?
Why offshore? Difficulty to find a suitable
location along the Italian coast for an onshore LNG regasification terminal that would be approved for construction and operation
6 onshore terminal locations were studied during 2002, yet the location considered most likely to succeed was the offshore one
Zero environmental / safety impact on coastal cities
Minimal visual impact from coastline
Why FSRU? Moss Maritime had been
investigating the concept early 2002 and had done feasibility studies which became the starting basis of the project
Why offshore Livorno? Strategic entry point into
Italian Gas Grid with most consumers in northern Italy
Exact location had been used to dispose the dredged waste from expansion of Port of Livorno many years earlier, hence undersea life is minimal
Close proximity and full availability of all required marine support services from Port of Livorno

Distribution of gas demand and infrastructure in Italy
Consumption of Gas by Region Existing and planned gas infrastructure in Italy
Italian demand for gas is concentrated in the central northern regions
Existing and planned importation capacity is concentrated on the Ionian / Adriatic side
80% of the demand comes from the Centre-North OLT is a strategic entry point into national grid resulting in lower connection costs compared to south and east

Complex Design & Construction Aspects
Newly built turret welded to the bow of the FSRU acts as single point mooring to allow the unit to weather vane, designed for the 100Y condition
Huge bilge keels added in order to stabilise the FSRU
Regasification module built offsite and installed with single 2,000 tonnes lift, max capacity of 450 t/hr (15 MSm3/d Gas), keep-cool mode via micro-sendout for instantaneous sendout
Significant structural changes to existing LNG carrier were required for conversion into a Floating Storage & Regasification Unit (FSRU)
Tanks Consists of 4 spherical Moss-type tanks More suitable for partially-filled terminal in offshore environment (anti-sloshing)
2 x 10 MW Steam Turbogenerators installed in engine room in addition to the 2 x 3,5 MW ones
Very Low Environmental limits: Max DT of SW is -4.6 K, Max free chlorine in SW of 0.05 mg/l (drinking water for human consumption is 0.2 mg/l), No venting except for emergency , NOx emissions limit of 150 mg/ Nm3, max limit of NOx emissions of 100 ton/y
Smaller module for nitrogen generation (Wobbe Index Correction) also built offsite to deliver on-spec sales gas + fiscal quality control and measurement module
DCS, ESD, F&G completely re-designed
LNG loading arms (traditional Jetty-type) designed with largest ever motion capability for offshore use in side by side up to 2,5m Hs @ 12000 cm/h for LNGC 65k to 155k cm
New high capacity transfer pump installed in each aluminium Moss sphere tank
Terminal is completely self-sufficient and has the same operational features as typical onshore regasification terminals

Rules Compliance
The Terminal complies with International regulations as well as Italian National and Local requirements:
Italian Law and Permits (Extensive)
IGC code
Recognised Industry guidelines, SIGTTO and OCIMF
RINA Class Rules (for LNG Floating Units)
SOLAS
MARPOL
ISM & ISPS
And by incorporating the necessary local safety and environmental requirements

Operations & Maintenance
Management and responsibility for all operations has been subcontracted to ECOS Srl a joint venture company founded in 2010 by Fratelli Cosulich SpA (40%) and EXMAR (60%)
ECOS has sole responsibility as Armatore for the terminal
Fratelli Neri SpA provides all the marine support service:
Custom-built Guardian Vessel with fast rescue boat and emergency evacuation for 40 persons
2 x Custom built tugs of 110 tonnes bollard pull
Custom Built Crew Boat max. speed 28 knots

Safety & Security
Significant rules imposed by Maritime Authority must be respected:
2 mile exclusion zone to be enforced 24/7 via Guardian Vessel
All transfer of personnel and materials must be prior-approved by Maritime Authority and originate only from dedicated onshore base, design and operated in accordance with ISPS rules
24/7 watch from wheelhouse despite radar monitoring in CCR and on Guardian Vessel
Port of Livorno Pilots onboard LNG Carrier during whole maneuver and LNG transfer operation
Port of Livorno Mooring Gang onboard terminal during ship-to-ship mooring operation
Integrated Radar and CCTV system of Maritime Authority to become operational in future

-
Where now?
Terminal is fully operational and open for business
Regasification capacity slots are marketed on a monthly basis on the company website
The terminal is currently with LNG and available for gas export at short notice
Italian government has declared OLT terminal as a strategic infrastructure for the Italian energy system due to the peak-shaving availability in the event of interruption of pipeline gas supply during critical winter months
Expectation is for increased utilisation resulting new LNG export projects from North America, East Africa and Australia from 2017 onwards
