Different methods of saving fuel in ships are briefly discussed, for example by proceeding at a lower than service speed. The saving may also be achieved in many ways during the course of design, by waste-heat recovery or utilisation of heat derived from the various intermediate processes, e.g. compression of the scavenging air. Another example is the novel approach of the Burmeister & Wain Shipyards in Denmark that attached a propeller with a 50% larger diameter than customary to a Panamax bulk carrier. Further chances of saving in fuel costs exist through long-range contractual commitments, with a policy of storage in the ships themselves and utilising dual-purpose tanks. Emphasis is laid on the technical aspects of the rational use of fuel in existing vessels in order to save on the quantity consumed without affecting performance and without the need for changes or modification. The Israeli-controlled merchant fleet consumes about 1.2 million tons of fuel a year and it is considered that roughly about 12% of this could be saved by using the means discussed.
