A Study to Obtain Verification of Liquid Natural Gas (LNG) Tank Loading Criteria.

摘要

A study of LNG tank loading criteria is presented that includes a survey and review of load criteria presently employed in the design of cargo tanks for LNG carriers. Motion and acceleration values as determined from these criteria are compared to ship motion calculations and available full-scale data. A comparison of LNG tank loads,as predicted by current classification society and regulatory agency criteria,is given along with recommended updated criteria in each of seventeen load categories. Model tests and fullscale measurement programs to provide adequate data for verification of load and acceleration criteria are also outlined. (Author)
