SBM Offshore starts marketing LNG FPSO
SBM Offshore has started global marketing efforts for an LNG FPSO with a proposed schedule to commence production of gas from the first unit in 2012.
SBM Offshore sees the LNG FPSO as a means to develop gas reserves that were previously seen as either stranded (remotely offshore) or impractical for development using pipeline export or onshore liquefaction. Providing a solution for floating liquefaction of natural gas means the industry may rethink the way it values gas assets. e LNG FPSO.
Although most components are already in service, an LNG FPSO is technically quite complex and capital intensive. To shorten the design and delivery cycle time, SBM Offshore is in a partnership with Linde A.G.
Linde and SBM now say they we have reached the stage where they consider the LNG FPSO ready for marketing.
The hull is a major critical component of the LNG FPSO and, after evaluation of the technical options available, the self-supporting, prismatic, IMO Type B (SPB) LNG tank technology developed by IHI of Japan has been retained for the storage of liquefied gas. The choice was driven by considerations such as accessibility for maintenance, robustness and therefore long-term offshore life availability and redeployability. This hull can also be adapted to suit the requirements for floating storage and regasification units (FSRU).
SBM and IHI have signed an agreement for the detailed engineering and construction of LNG hulls.
SBM has funded IHI to develop the basic design of a 230,000 cu.m multifunction hull. The long-term agreement provides that IHI offers its construction capacity at the Aichi Works for an early project.
The Linde Multi-stage Mixed Refrigerant (LiMuM) process has been selected for the liquefaction system based on its thermodynamic efficiency, robust design, compactness and proven performance. The FPSO facility will be able to treat, fractionate, liquefy, store and export the LNG as well as any by-products from the gas field production such as LPG and condensates.
The nominal size of the developed facility provides an output of 2.5 million tonnes per year of LNG which, therefore, is typically suitable for fields in excess of 1 tcf recoverable gas reserves. The comprehensive topside design will enable the processing of almost any natural gas composition.
