This booklet is dedicated to the new and revolutionary technology. The study of the technical design and economic feasibility for an electric-driven ULCV capable of transporting twenty thousand container units, with an LNG-fuelled combined cycle gas & stem turbine power plant, was conducted by GT, CMA CGM, CMA Ships and DNV GL Classification Society.

The vessel is equipped with the LNG membrane tanks for one full return voyage between Europe and Asia. The high-level research work performed by the above stated entities addresses the fuel efficiency and contains preliminary economic assessment. It is quite clear to everyone that LNG may be treated as the perfect fuel for gas turbines. It is very clean and allows to increase the turbine inlet temperature and, in turn, its efficiency. In addition, increased temperature at the turbine outlet allows to install the high-efficient steam turbine cycles using the exhaust gas coming from the turbine.

That is why COGAS, standing for the COmbined Gas and Steam Turbine way of generating power is considered one of the most effective ways - the efficiency of the power plants working on the LNG may achieve 60% which is unachievable level for the diesel engines, reaching to that 52% max.
