Shipping liquefied gases is a fascinating combination of science & history, technology & mystery. Historically, the thermodynamic theory of gas liquefaction has been well understood for over 100 years. The design of gas ship cargo systems evolved from the 1930's until the present date - reaching a technological plateau some years ago. Since then the main changes in the gas ship trades have been commercial.

Gas ships now trade between an increasing number of different ports, carrying a wider range of cargoes than before, often transferring them ship-to-ship. Charterers expect cargo operations to be carried out more efficiently & economically, while often not appreciating how to obtain the optimum results from the cargo system. And it is in the realms of cargo system operations that lie the greatest mysteries of liquefied gas shipping - especially the combination of art & science involved when "changing grade" from one cargo to another.
