Coupled tank sloshing and lng carrier motions

WebSep 16, 2013 · This article presents a numerical study of the coupled ship motions and tank sloshing of a liquefied natural gas carrier. To solve this coupled problem, we have developed a time-domain numerical method. The method combines a ship motion solver based on strip theory and a computational fluid dynamics sloshing solver. WebDuring LNG delivery and offloading operations, interactions between ship motions and internal LNG sloshing would affect the stability of LNG carrier and also lead to the …

WebAbstract: Liquid sloshing phenomena in No. 2 tank of 140km3 liquefied natural gas (LNG) carriers have been studied numerically and experimentally. The scale of the model tank was selected as 1/55.9. Roll and pitch motions were tested. For measuring impact pressures, seventeen pressure sensors were installed on the tank model. WebDec 1, 2011 · To evaluate the performance of membrane-type LNG carriers under half-loading conditions, simulation for coupled ship motion and sloshing has been carried out by using a newly developed time domain scheme. The external fluid field was solved by potential theory, while the internal fluid field was solved by a 3D finite difference method. … WebSep 26, 2024 · This paper discusses the coupling influence of floating LNG (FLNG) motions with internal liquid sloshing.

WebThe traditional choice of insulation material for liquefied natural gas (LNG) transportation with cryogenic tankers is the back-filled perlite-based system. However, aiming to further cut down the insulation cost, spare additional arrangement space, and provide safety in installation and maintenance, the requirement of looking for alternative materials still … WebExxonMobil has also conducted a model test of a large LNG carrier [3]. Both these experiments demonstrated that coupling effects significantly influence lateral motion, with a much smaller effect on longitudinal motion. Nasar et al. [4] investigated coupled sloshing and ship motion using a barge with one rectangular tank in regular beam waves.
