PREDICTION OF LIFETIME EXTREME ACCELERATIONS FOR DESIGN OF LNG CARGO TANKS

A procedure is developed to predict the extreme accelerations needed for design of the cargo tanks in LNG vessels. Extreme values of accelerations for the lifetime of a ship are obtained by applying short-term statistics to extreme sea conditions collected over many years. The predictions are presented in the form of unit wave height response surfaces as a function of ship heading and wave period. By applying published wave statistics to these response surfaces, extreme response surfaces are determined for selected oceanic locations (shipping routes) in the world. (Modified author abstract)
