PROPULSION UPDATE MAN B&W HOLEBY LI 6/24 Genset Wins Design Prize The MAN B&W Diesel Holeby genset type L16/24 recently won a 1996 Industrial De-sign Prize. The ID Prize is awarded in recognition of good industrial design. The L16/24 was introduced in September 1995. It was designed to provide better soundproofing, easier cleaning, easier mainte- nance, better fire protection, a bet- ter work environment, and greater flexibility. To make the unit easier to maintain, a modular mainte- nance design approach was taken. All support elements, such as fil- ters, coolers and thermostatic valves, are designed to be removed easily, due to the clip-on/clip-off principle, and to the incorporation of piping channels within the engine structure, rather than external mounting. The cylinder unit concept is designed to offer other benefits. Overhauling is designed to be carried out easily and swiftly on the basis of recy- cling, minimizing the genset shut- down period. MAN B&W reports that recycling makes it possible for the complete cylinder unit to be removed in one step and replaced with a new unit, allowing the over- haul to be performed onboard ship, or ashore by the owner or the man- ufacturer. The engine controls its own oper- ating conditions through the auto- matically controlled cooling water system, which is a single-string system with only one inlet and one outlet to the external system. The system is equipped with pumps and thermostatic valves for both high and low temperature circuits, to ensure that both circuits will always have optimal temperature conditions. In addition, a valve regulating the charge air tempera- ture is installed. If the loading is below 40 percent, the charge air temperature will increase to a level yielding the best combustion condi- tion. The valve regulates the low temperature, not as an on/off func- tion, but by constantly adjusting to the load level. The engine's automatic control equipment is arranged for compat- ibility with MAN B&W Diesel's CoCos system, which facilitates engine diagnosis and optimized planning of overhauls. On top of these performance demands, the designers sought to reduce the number of components by 40 per- cent.
