COAL-FIRED SHIP MAY ALREADY BE ECONOMICAL

Y-ARD's report to the Ship and Marine Technology Requirements Board considers that at 1980 oil prices it appears that coal-fired ships would show a small cost advantage on certain coal trade routes, and this is likely to increase with possible higher prices and more advanced technology. The Report concentrates on fluidised-bed combustion, since the technique is said to offer the greatest potential for coal-fired ships in medium term. It is considered that UK manufacturers should concentrate on research and development in this field, so that British yards can secure the orders that may soon be forthcoming. Australian interests are already negotiating with Japanese yards for building a coal-fired ship for the East Asiatic coal trade. With pneumatic handling of up to 50-mm diameter coal, the location of bunkers near the machinery space may become less critical. The design visualised by the Report is a modified Panamax bulk carrier, based on the MV Caledonia. Remotely controlled, totally enclosed conveyors would take coal from the main bunkers directly forward of the engine room to a ready bunker. In coastal waters, ash would be stored in a tank holding 10 days port output. At sea the ash would be discharged into the wake and dispersed without harm to fisheries or coast lines.
