Summary

Methane carriers are transports which use the portion of their liquified gas cargo which evaporates during the voyage to fuel the boilers which feed the steam-propulsion turbines. The cost of transport could be reduced if, as the paper proposes, the boilers were replaced with diesel motors of greater output capable of burning gaz or alternatively liquid fuel. These motors would be used for a diesel-electric propulsion of the type whose qualities have already been largely proven, especially on cruise ships. The new plant compares favorably with classical plants from the point of view of reliability and redundancy. In addition to the gain in output, the plant makes it possible to assure, as with steam ships, the dissipation of excessive evaporated gas, when the ship stops. The reduced size of these plants also makes possible noticable gains in the dimensions of the ship.
