Fast-forward – GNLS del Plata LNG

Published: May 19, 2014

Accelerating gas delivery; Floating Storage and Regasification Unit (FSRU) LNG solutions, as in Punta Sayago, Uruguay, are a growing trend. Providing “one-stop” expert engineering on the GNLS del Plata terminal, Tractebel Engineering reactivity helps pick up the pace from BOOT bid to execution.

A NEED FOR SPEED – FROM THE START

For end-customer Gas Sayago S.A., rapid development of LNG regasification capacity, a priority within Uruguay’s long-term Energy Policy, is key. With an FSRU terminal foreseen 4 km offshore from Montevideo, Tractebel Engineering/IMDC worked fast with GDF SUEZ Energy International (GSEI) to prepare a BOOT (Build, Own, Operate and Transfer) bid to secure the 15-year contract for the world’s first “FSRU MAX” LNG terminal.

THE WORLD’S FIRST “FSRU MAX” PROJECT TAKES SHAPE

The GNLS del Plata LNG terminal is designed to berth a permanent “FSRU MAX”, 345 m long and 55 m wide, with 263,000 m3 storage and a regasification capacity designed up to 15 M(S)m3/day. Yet a smart interim bridge FRSU solution will ensure gas supply in just 20 months… Read more

A NEED FOR SPEED – FROM THE START

For end-customer Gas Sayago S.A., rapid development of LNG regasification capacity, a priority within Uruguay’s long-term Energy Policy, is key. With an FSRU LNG terminal foreseen 4 km offshore from Montevideo, Tractebel Engineering/IMDC worked fast with client GDF SUEZ Energy International (GSEI) to prepare a BOOT (Build, Own, Operate and Transfer) bid to secure the 15-year contract for the world’s first “FSRU MAX” LNG terminal.

WHY OFFSHORE FSRU LNG?
Beyond providing access to a cleaner fuel source, offshore FSRU LNG terminals save space onshore; the faster delivery of a commercial LNG terminal is also a main driver. While construction of an onshore LNG storage tank can take up to 36 months alone – an FSRU LNG solution can feasibly be achieved in less than 2 years. The flexible deployment of FSRU assets is also an advantage. While still a growing trend, as a proven technology, supported by increasing FSRU vessel availability, offshore LNG terminals have an important role to play!

STEPPING UP TO THE BOOT BID
However, proven technology does not equal an “off-the-shelf” solution. Helping GSEI to assess the feasibility and project criteria in order to prepare an effective bid and ensure smooth development, Tractebel Engineering Power & Gas and IMDC (International Marine & Dredging Consultants), has contributed to the project from the start.  This involved studies to develop the design concept, procurement needs and CAPEX estimations. An accelerated FEED (Front to End Engineering and Design) study was also done; validating and optimising the CAPEX estimations, while clarifying the design specifications needed to launch an EPC tender.

Early key tasks achieved included:

  • Full preliminary basic design of the terminal.
  • Forward tendering for major parts of the topside installation: the loading arms and the ship gangways.
  • Metocean and hydrodynamic studies, numerical modelling, and soil investigations to ascertain the seabed dredging requirements and optimize the breakwater and jetty solutions.
  • A Reliability, Availability & Maintenance (RAM) study of the HP gas send-out.
  • FSRU selection (bridge solution and FSRU MAX requirements).
  • Creation of a 3D model of the proposed installation

CONTRACTS SIGNED ON ALL SIDES

In October 2013, the final BOOT contract was signed between GDF SUEZ and Gas Sayago and the new owner/operating company GNLS was created. GNLS is now a joint venture between GSEI and Marubeni – for whom Tractebel Engineering/IMDC are the appointed Owner’s Engineer (OE).  The full turn-key EPC contract is with Brazilian contractor O.A.S.

In 6 months the GSEI project team and Tractebel Engineering/IMDC effectively developed a full LNG project and ensured its commercial viability – in terms of usual LNG project preliminary preparation and study phase timing – that is highly efficient.

THE WORLD’S FIRST “FSRU MAX” PROJECT TAKES SHAPE

The GNLS del Plata LNG terminal is designed to berth a permanent “FSRU MAX”, 345 m long and 55 m wide, with 263,000 m3 storage and a regasification capacity up to 15 M(S)m3/day. Yet a smart interim bridge FRSU solution will ensure gas supply in just 20 months…

THE GNLS DEL PLATA LNG TERMINAL
Located in the el Rio del Plata estuary, around 2 km south of Punta Sayago and 4 km from the Port of Montevideo; the terminal will feature:

  • An offshore breakwater, 1.4 km long, built with blasted, wave-dissipating rock, to protect the FRSU mooring and operating site.
  • A jetty head with berthing facilities to accommodate the dedicated “FRSU MAX” as well as receive offloading LNG carriers of up to 218,000 m3. All necessary equipment and piping needed to transfer Natural Gas is housed on the jetty.
  •  A service platform providing additional tug boat moorings, handling and connection facilities to the subsea pipeline.
  • A trestle and pipe rack connecting the jetty to the service platform and supporting the HP Natural Gas pipeline to the start point of the subsea pipeline connecting the terminal to shore.

INTERIM FSRU DICTATES SCHEDULE
The first of its kind in the world (nearly double the size of current FSRU vessels) the long-term FSRU MAX is being specially constructed for the project and will be ready for service in2016. Till then, the shuttle regasification vessel – GDF SUEZ Neptune, refitted to match the project criteria outlined by Tractebel Engineering, will serve as a bridge solution when operation of the terminal begins in 20 months as scheduled. Due to berth mid 2015, Neptune’s arrival marks the deadline by which major works must be completed.

CONSTRUCTION BEGINS EARLY 2014
Activity onsite has begun well:  under supervision of Tractebel Engineering /IMDC the marine works started: dredging is needed to deepen the access channel, vessel turning basin and mooring site (from – 6m to -15 m) to accommodate the FSRU MAX and delivery vessels. Then soil substitution will ensure a proper foundation for the piling works and the breakwater construction. Specialised laboratory 2D and 3D modelling tests to confirm the optimal final design of the breakwater at best cost are on-going.   On shore, a temporary construction site has been opened by the EPC where various structural elements of the terminal are to be built before being erected offshore.

TRACTEBEL ENGINEERING GIVES ITS “ALL” AS OWNER’S ENGINEER

Having combined competences to engineer the project’s multidisciplinary topside, alongside the marine works; Tractebel Engineering/IMDC’s multidisciplinary onsite team, supported by back-office experts providing ongoing advice and input, is now helping to further streamline the project progress.

MANY COMPETENCES – ONE POINT OF CONTACT
Tractebel Engineering is experienced in all LNG processes; with focus on the design, construction supervision and commissioning of complex missions.  Integrated with IMDC’s marine competences (dredging, environmental coordination, design and supervision of the breakwater and jetty construction), GNLS can rely on a full range of expertise while interfacing with one project management team. The improved interaction, quality and efficiency indirectly helping to further assist the project pace.

RESPECT, ANTICIPATE, RESOLVE
Ensuring that the project schedule is respected, a core team of 6 Tractebel Engineering and IMDC engineers has been mobilised onsite, where they are working alongside GNLS and the EPC contractor. Up to 15 more people from Tractebel Engineering and IMDC are also on hand to provide engineering support from Belgium. Altogether, taking an involved and proactive approach proven successful on other LNG projects, Tractebel Engineering’s main focus will be on the anticipation and mitigation of issues well in advance of their becoming more time-consuming or costly problems.

A PATTERN FOR THE FUTURE
Tractebel Engineering and IMDC are geared to continue this high-level involvement throughout the project providing: coordination, supervision and follow-up of all contractual, procurement, construction, pre-commissioning and commissioning activities, to ensure the project’s success. It is a win-win situation for the client, the EPC and Tractebel Engineering itself as, while each LNG terminal is unique, any experience gained from resolving new project challenges adds to the expertise taken to future projects. And given the way the LNG world is turning – there will be many more…
