after the shaft generator has been connected. By adopting a suitable simulating calculation method, an optimal in- ter-related behavior of all drive train components is studied, includ- ing the propeller, main propulsion engine, gear unit, shaft-driven gen- erator, and the mains supply includ- ing diesel-driven generators operat- ing in parallel. The high efficiency of the gear unit is one of the essential factors for the economy of the plant. The RCF system operates with an effi- ciency ranging between 93 and 97 percent. The system, which requires a relatively low capital investment, is also advantageous to use because of the potential fuel cost savings. Renk has sold approximately 30 RCF systems to be powered by M.A.N.-B&W two-stroke engines. This is a joint development of Renk and M.A.N.-B&W. Four 1,100-kw electrically controlled units are now in service on refrigerated container- ships with fixed-pitch propellers built at the German shipyard Brem- er Vulkan. Two 700-kw hydraulical- ly controlled systems are for 79,900- dwt tankers built at the Uljanik shipyard in Yugoslavia, and one 900-kw unit is on order for Burmeis- ter & Wain, Copenhagen. The German company's U.S. sub- sidiary is Renk Corporation of Dun- can, S.C.

Circle 315 on Reader Service Card 105 BFGoodrich rubber and IIHMWP Romor® bearing staves: first to be U.S. Navy qualified. When it comes to bearing staves, the Navy prefers the strong, silent type. That's why Romor brand bearing staves from BFGoodrich were first to be qualified by the U.S. Navy to Mil-B-17901B Class III specifications. A thin, soft, and very smooth rubber-surfaced lining backed by tough, non-corroding ultra high molecular weight poly- ethylene (UHMWP) reduces friction and allows Romor staves to outperform Class I hard-rubber, brass-backed staves. Romor staves are quieter, lighter, less expensive, more readily available and more energy-efficient than metal-backed staves. Which explains why they are used on more than 100 U.S. Naval and Coast Guard vessels, as well as by the navies — of many other nations. f ^^^ \ So, for new or retrofit marine applications, follow \ ^PPJ a naval tradition.
