Little attention has hitherto been given to sloshing in ships' tanks filled to 90% or more, not only because the liquid motion can be expected to be less than in tanks filled to lower levels, but also because the structural members in the top of a tank will reduce sloshing if the tank is almost full. However, with the development of membrane or semi-membrane tanks with hardly any internal members, sloshing at high filling ratios cannot be ignored. The Authors (of Hitachi Shipbuilding) give an account of tests on LNG tank models. They were carried out to investigate sloshing loads in tanks filled to 90% and above, with the main object of obtaining information for estimating sloshing loads in actual conditions at sea. Impact pressures were measured, and a large quantity of data was obtained and analysed. The results are given in detail and discussed.
