Braemar’s FSP receives General Design Approval

Braemar Technical Services has announced that Bureau Veritas (BV) has issued a General Design Approval for the FSP Type B LNG Containment System (FSP).

Starting with the General Dynamics NASSCO-patented tank design, for which ABS and Lloyd’s Register had issued Approval in Principle (AiP) several years prior, Braemar engineered a new and improved containment system that meets the rigorous demands of LNG storage in marine, offshore, and onshore applications.

The containment system technology development project was a success in great part, due to the commitment from and close co-operation with joint venture partners Honghua Offshore Ltd., EnTX Group, and Jamestown Metal Marine Services Inc.

BV issued the approval after witnessing the successful cryogenic testing of a prototype built by Shanghai Aerospace and outfitted at Honghua’s world-class facility in Shanghai, China.

The enhanced FSP design incorporates several unique elements, including the following:

  • Cost to construct FSP tanks is lower than equivalent IMO Type A, spherical Type B, other prismatic Type B, and Type C tanks for most size ranges.
  • FSP tanks are fabricated and outfitted in a clean, dedicated facility in parallel with hull or plant construction, shortening the critical path relative to projects utilising membrane or conventional land-based tankage and ensuring the highest levels of quality control.
  • Volumetric efficiency of FSP tanks is flexible to meet project specific requirements and is higher than the latest spherical IMO Type B and all IMO Type C tanks, and is comparable to equivalent IMO Type A tanks.
  • FSP tanks are inherently more robust than IMO Type A and membrane tanks, and are less sensitive to construction tolerances than other IMO Type B tanks.

The advantages of the FSP containment system are already being incorporated in the design of the LNG 21 export project, which is under development in the US Gulf of Mexico. In their capacity as Owner’s engineer, Braemar, in conjunction with Wood Group, are currently carrying out the FEED for the project, which includes an FSP system with a total storage volume of 300 000 m3.

Sheila McClain, Braemar’s Global Head of Engineering & Naval Architecture, said: “We would not have achieved this historic milestone without the hard work and support of the JV members […] We are eager to commercialise the technology and are already working on several projects where stakeholders, such as the LNG21 developers, are excited by FSP’s combination of favorable economics, robust design, and short critical path from concept design to commissioning.”
