Abstract
The demand for larger ocean-going vessels carrying LNG and LPG under low temperature is increasing year by year.As you are well aware, the economic factors which hold sway over the design of the said tanker are far different from an ordtnary oil tanker's one.In this respect, this paper reports the historical progress of low-temperature liquefied gas tanker up to successful operation of M.S.“Bridgestone-Maru”and some factors which might influence a design of future vessels of this type.Further, it states hull shape and scantling as well as the optimum arrsngement of cargo tank spaces, design and construction including material for insulation and construction for both cargo tank and hold.Not only, liquid transferring system necessary for handling of the cargo, auxiliary system, gas-treatment system and arrangement of instruments for measurement, also the outline of special technique of construction of the said tanker are described hereunder.
