This paper discusses the likely influences on the future competitiveness of steam propulsion. Whilst slow speed diesel propulsion has had a clear economic advantage since the high fuel cost increase in 1973, it will not necessarily maintain this position in the long term. The main influencing factors, apart from future price increases, are the available fuel quality and type of ships to be built. Future tonnage requirements are likely to vary widely in type but large scale building of mammoth vessels is not foreseen in the near future in the sensitive shipping market. Great uncertainty exists with the quality of fuel available but while steam turbines and slow speed diesels are competing on the basis of the same fuel viscosity then the diesel will maintain its position. However, it is believed that, in the long term, i.e. 1985 onwards, the diesel may not be able to compete in the higher power range if heavier viscosity and lower quality residual fuel becomes more prevalent.
