EVALUATION OF STEAM AND GAS TURBINE POWER PLANTS IN CONTAINER SHIPS

Comparative data is presented to permit economic evaluations of steam and gas turbine propulsion plants installed on fast container ships. Specific ships, designed for a fast and two relatively slower services over New York to Hamburg and San Francisco to Yokohama trade routes, are evaluated on the basis of three types of propulsion plants: an 850psi-950 F conventional steam turbine installation and two gas turbine plants, one utilizing General Electric LM2500 turbines and the other Pratt and Whitney FT4 units. Common amounts of cargo and service speed on all dry cargo ships designed for the same service enable valid comparison. Basic plant economics were compared without penalizing gas turbine plants through selection of uneconomical operating levels. It is concluded that lower annual fuel costs of steam plants give them a large advantage over gas turbine plants. Fuel costs set forth in Appendix C are a critical factor in determining the economics.
