摘要

The enthusiasm of the market for liquefied natural gas pushes shipowners, charterers and shipyards to develop 'tailor made' projectsadapted to the new constraints of the LNG chain. This evolutioninvolves, not only increased cargo capacity, but also specific operatingconditions well suited for off-shore applications. To assess the viabilityof membrane design, dedicated liquid motion studies are requested. Theinitial step of a complete sloshing assessment consists in a full seakeepinganalysis to anticipate the behaviour of the ship during herwhole life. Gaztransport & Technigaz (GTT) continuously improve thisfirst step of their methodology supported by a large R&D program. Thethree main fields of recent improvements deal with:1. Environmental conditions;2. Coupling effects;3. Off-shore projects.This paper describes the main improvements on these different itemsintegrated into GTT's methodology for sloshing assessment.
