The 12-cylinder medium-speed diesel engine com- pleted the 1,000-plus hour test at varying power levels, up to 110 percent of the 15,900 rated bhp. The test involved quick accelerations and ex- tremely high power levels, requiring the burning of one truckload of fuel every eight hours. Wartsila conducted the test at its own expense in order to qualify for participation in such projects as the U.S. Navy's Strategic Sealift and LPD (amphibious ship) projects. With the completion of this test, the entire Vasa 46 series of seven engine models ranging from 5,200 bhp to 23,500 bhp is now qualified to MIL-E-23457. The Vasa 46 will be manufactured at Wartsila Diesel's new production facility in Mount Vernon, Ind. The existing site, originally built by Wartsila Diesel's manufacturing partner Babcock & Wilcox, is undergoing modifications in order to perform the necessary fabrication and testing functions for the Vasa 46. According to Thomas M, Carbone, vice president of manufacturing and general manager of the Mt. Vernon plant, Wartsila Diesel's venture is unique to U.S. shipbuilding in that a leading international supplier will manu- facture its top product line in the U.S. For more information on the products and services offered by Wartsila Diesel North America.

According to Matt Smith, E company spokesman, the product works like this leakages or spills of fuel and lubricants into e boat's bilge shape into large globules or a slick Bacteria, either naturally occurring or induced will break down and consume these bilge oils anc their odors. Bilge Bugs Part A speeds up this process by emulsifying the spill, breaking it dowr into microscopic particles, and then encapsulat ing each of these particles with a nutrient-bear ing surface. The process, called emulsification encapsulation, reportedly provides more surface area for accelerated biodegradation.
