SOME ASPECTS OF THE CLASSIFICATION OF LOW TEMPERATURE GAS CARRIERS

The principal safety problems involving the low temperature gas carrier are related specifically to the temperature of the cargo, which itself is no more of a 'problem' cargo than crude oil. This paper illustrates the philosophy of the Classification Society in dealing with its responsibilities as regards a new type of vessel in a manner which marries safety to a flexibility in action that does not in any way inhibit the development of new techniques. A warning note is sounded about the current concern of I.M.C.O. with gas carriers and its proposals for a construction code for these ships. Mention is made of the Classification Societies' work in tank structure; its attitude towards dispensation of the secondary barrier and its concern with such important safety matters as free surface effects, membrane damage, temperature control and spilled liquid. The paper draws attention to the high safety record for this class of ship.
