- Gas carried on LNG carriers is liquefaction gas at ambient pressure and temperature minus 163oC degree is subject to boil-off and causing increase in pressure. This phenomenon makes danger of explosion. The simplest possibility to circumvent the foresaid event is to release-liquefied gas to atmosphere. However, the mentioned way causes losses of cargo and air pollution. There is an option to re-condensate gas again nevertheless to do it extra energy is required. Method that is more rational is to use boil-off fuel gas as propulsion energy in diesel engines, gas and steam turbines. This paper describes exploitation costing of main propulsion on LNG carriers trying to find out the best solution. There are presented fuel gas supply system as well various type of engine driven by fuel gas. Moreover, author presents further design development of LNG carriers. Possibilities of cost reduction related to boil-off fuel gas, the Moss RS standard setup for gas reliquefaction system, example of dual fuel diesel engines and electric propulsion, basic design concept for two compressor units 100% type 6LP250-5S1, diagram of COGES system, thermal efficiencies for the different propulsion options, technical data of some present dual-fuel engines, as well two-stroke propulsion recommendations for LNG carriers are illustrated in the paper.
