Det norske Veritas Authorized For U.S. Tonnage Admeasurement The U.S. Coast Guard recently entered into a Memorandum of Agreement with Det norske Veritas (DnV) to perform tonnage admeasurement on the Coast Guard's behalf. With the enact- ment of this agreement, owners of all U.S.-flag vessels now have an option on which they may approach for admeasurement services. In conjunction with this agree- ment, DnV has appointed Phil Essex to coordinate tonnage ser- vices throughout North America. Mr. Essex has previously served as a tonnage admeasurer for the Ameri- can Bureau of Shipping for 10 years, with a broad background in U.S., Panama and Suez Canal regulations as well as serving as ABS-Americas specialist in the 1969 Tonnage Con- vention. DnV, a major international clas- sification society formed in 1864 in Oslo, is a charter member of IACS (International Association of Clas- sification Societies) and currently maintains class on approximately 15 percent of the world fleet totaling over 62 million GRT.

WesTech, Cosworth Sign Licensing Agreement For Closed Cycle Systems WesTech Gear Corporation, Lynwood, Calif., recently announced its exclusive U.S. licensing agree- ment with Cosworth Deep Sea Sys- tems, Ltd. (CDSS) to sell, manufac- ture, install and service Closed Cycle Systems for use with diesel engines. CDSS has developed a Closed Cycle System which is able to condi- tion the exhaust gas from a diesel down to 3,000 meters while uniquely maintaining surface efficiency. The exhaust conditioning system can be used with various prime mov- ers including diesel engines. Ongo- ing research has commenced regard- ing the application of the gas condi- tioning system to fuel cells. Although the most immediate applications are military, there are potentially many within the offshore oil exploration and other deepwater research activities. The Closed Cycle System allows, for the first time, a diesel engine to provide both significant underwa- ter power generation and propul- sion. This is achieved by the use of a pressure-balanced water manage- ment system and absorber which can condition engine exhaust gases and discharge them overboard at any depth without draining power from the diesel engine. Less than 15 percent of the engine's power is re- quired for this task. The principles of the system lie in April, 1992 recycling the exhaust gases to the engine intake after adding oxygen and removing carbon dioxide in the correct proportions. The basic design criteria included the following requirements: autono- mous power supply unit; extensive output from 5 kw to megawatt range; completely depth independent; high responsiveness to power demands; low auxiliary power requirement; simple robust low maintenance sys- tem; and ability to use off-the-shelf technology. Militarily it is envisaged that the maj or application for the system will be as a power source for conven- tional submarines. There are also applications for torpedo propulsion and for autonomous unmanned submersibles for covert operations. In civilian guise the role of the system will include specific applica- tions in the oil and gas industry for the reduction of carbon dioxide in gas pipelines; power sources for ocean bed development and explo- ration; pile hammer energy sources for the oil and gas industry in off- shore locations; remote operated vehicles for oil rig and pipeline in- spection and for submarine propul- sion in oil and gas exploration.
