MARITIME FUEL CONSERVATION

A three-year survey of means for fuel conservation in the maritime industry has produced a series of reports and memoranda summarized herein. Topics covered included ship operational practices--such as speed reduction and rationalization of ship schedules--increasing the efficiency of ship hulls, power plants and propellers, improved navigation aids and a search for alternative fuels, including those that are not petroleum-based. A broad industry/government plan is formulated, suggesting how best to cope with either moderate or severe fuel shortages in the short term, as well as in the long term. Recommendations for the industry and government include: ship speed reduction by various means; improved power plant efficiency, especially at reduced power output; improved weather routing and reduction of lost time at sea; trial installations on ships of modified propellers, monitoring of hull roughness and of powerplant performance; evaluation of diesel engines and more efficient steam power plant cycles; trial use of coal/oil slurry fuel, and continued study of oil from coal and of hydrogen-based fuels; development of rules or legislation, or both, to facilitate rationalziation of scheduling of U.S. flag lines and improvement in intermodal LCL cargo services to compete more effectively with air freight.
