METHANE CARRIERS AND HARBOUR FACILITIES

After a brief description of the sea transportation of LNG to date and the foreseeable development of this means of conveying energy, the author draws a rapid picture of the technical evolution of methane tankers with particular reference to type of cargo tanks adopted: parallelepiped, self-supporting cylindrical or spherical, or integrated tanks. Problems particular to methane terminals are reviewed. Some of those are common to loading and discharging terminals and include problems concerned with storage tanks or those related to safety and the possible consequences of leakage. Other difficulties are peculiar to LNG unloading terminals. The different features of these terminals are described and attention is drawn to the limits of "coldness" recovery during the regasification process. Another important aspect particular to the gas industry is discussed; the adjustments necessary to give the supplied gas qualities and combustion characteristics similar to those of the gas previously deliverd by the transmission system which the terminal feeds. In the conclusion the author emphasises the fact that the sea transportation of LNG is somewhat inflexible. It is necessary that international co-ordination should relieve this inflexibility and thereby contribute to the development of this means of transporting energy.
