LIQUEFIED GAS SHIPS--DESIGN PROBLEMS

Because of the low temperature of the cargo it is essential that great care be taken in development of details in the hull structure to avoid high concentrated stresses. Such details will be illustrated in this presentation. The various options in ship proportion, design details, containment system, etc. are discussed. The choice of a containment system would most likely be an economic one based upon ship delivery time, cost, etc. It is the writer's opinion that the ideal liquefied natural gas containment system may not evolve for a number of years. The IMCO "Code for the Construction and Equipment of Ships Carrying of Liquefied Gases in Bulk" has now been adopted. The implementation of this code may further add to the costs in liquefied gas construction. ABS views on this code and its impact on liquefied gas ship designs for vessels obtaining a U.S. Coast Guard "letter of compliance" are discussed.
