CONSTRUCTION OF LARGE METHANE TANKERS

Due to the characteristics of LNG, particularly its very low temperature (minus 161 C or minus 258 F), special techniques must be used for the construction of the tanks. As is known, these techniques are divided into two categories--the self-supporting techniques and the integrated membrane techniques. Excellent techniques exist both in the self-supporting and the integrated category. On the other hand, from the cost point of view the integrated techniques possess a definite advantage. Moreover, every time that these two types of techniques were taken into consideration on a competitive basis when receiving orders for methane tankers, it appeared that the integrated techniques led to the lowest prices. The economic advantage of the integrated over the self-supporting techniques in the construction of large methane tankers is due to the fact that the integrated techniques make use of technologies which, though new in marine construction are well adapted to the very special conditions of LNG transport.
