Fuel oil and lubricating oil costs are compared with the other running costs of large ships and are shown to be a substantial fraction of the total. The various drag forces exerted on a ship are compared and the individual properties which influence most of the major drag force, friction, are identified. A number of techniques for reducing friction forces are considered, some proving practical and some the reverse. The effect on oil consumption and costs of one technique in particular, that is the removal of water from the bottom of the ship by means of a compressed air cavity, are considered. /AUTHOR/
