THE EFFECT OF HIGHER FUEL PRICES ON THE DESIGN OF SHIPS

Changes in ship design due to increased fuel prices are discussed taking as example the hullform of a tanker capable of transporting 3.6 million tonnes of crude oil per annum between the Persian Gulf and Japan. The "Net Present Worth" method is used to develop relationships between optimum speed and fuel and freight rates for a 270,000-dwt turbine tanker and a 136,000-dwt Diesel tanker to operate on the same route. Finally, the feasibility of low powered Diesel ships with turbo-generators and ducted propellers is examined. It is concluded, inter alia, that the operational speed of tankers will decrease by two to four knots, depending on size, and that turbo alternators and/or ducted propellers will come into increasing use on smaller Diesel-powered ships.
