    ABS to class the world's first newbuild LPG FPSO

    News // October 25, 2002
    The world's first newbuild liquefied petroleum gas (LPG) FPSO, slated for operation offshore Angola, has been announced with ABS selected as the classification society of record. The vessel, to be named the SANHA LPG FPSO, will have a daily production capacity of 6,000m3 andstorage capacity of 135,000m3.

    "Demand for LPG FPSOs is being driven by environmental concerns that have placed severe restrictions on the traditional method of flaring gas associated with production," says ABS Vice President, Offshore Project Development, William J. Sember. "By capturing these gases not only does the environment benefit, but also with the demand for gas forecast to double over the next decade, industry and consumers will benefit from this new technology."

    The SANHA will include LPG storage tanks and LPG production plants such as gas separators, gas refrigerators and boil-off gas reliquefaction units on the upper deck or topsides.

    Sember says ABS is uniquely qualified to review this vessel's configuration because it is the only classification society to have experience with the type of liquid gas containment system being used for the SANHA LPG FPSO.

    The vessel will utilize Ishikawajima Harima Heavy Industries' Self-supporting, Prismatic-Shape, IMO Type-B tank system or SPB. ABS has previously classed the only LNG carriers to use this containment system and also classed the first LPG FSO newbuild, the Escravos, which is fittedwith SPB tanks. The Escravos is in service for ChevronTexaco offshore Nigeria.
