Sloshing Assessment of Membrane LNG Ships and FLNGs Seminar

Lloyd's Register is responsible for the development, implementation and maintenance of standards for the design, construction and operation of ships and offshore units. These standards, or ‘Rules’ are supplemented by additional verification procedures which are often assessed using advanced structural analysis techniques or similar direct calculation programs.

One example of this is the assessment of the strength of the LNG cargo containment system to resist sloshing actions, the assessment of the design sloshing loads and the assessment of the structural response and capacities are very complex and a simple definitive procedure is no longer applicable.

Lloyd's Register "Sloshing Acceptance Guidance Document for Membrane Tank LNG Operations" gave recommended design methods for the assessment of the cargo containment system. This talk reviews some of the issues associated with the development of this document, related research tasks and also the processes followed by Lloyd's Register in the design appraisal of LNG cargo containment systems and the recent application to FLNGs.
