(MES) and its fully-owned subsidiary Burmeister & Wain Scandinavian Contractor AS (BWSC) have deliv- ered a 100-MW, low-speed, two- stroke, diesel-driven electric pow- erplant — one of the most powerful in the world — to Companhia de electricidade de Macau (CEM).

The new ratings for the 930 c.i.d. (15.24 L) diesel are: high output, 799 hp at 2,100 rpm; medium duty 600 hp at 2,100 rpm; and continu- ous duty 500 hp at 1,800 rpm. The 700 hp rating is already at work in 32 ft. (9.7 m) Bristol Bay gillnet- ters in Alaska. The new model's high output L6140AL2's cooling system fea- tures a new, higher capacity, gear- driven jacket water circulation pump. Keel-cooled models have a new centrifugal pump dedicated to the freshwater aftercooler cooling circuit. On heat exchanger cooled versions, a supplemental heat exchanger has been integrated into the aftercooler cooling circuit. Other changes include new con- necting rod bearings, 12-hole fuel injection nozzles and turbocharger. For more information on Lugger Circle 93 on Reader Service Card NNS Wins Contract To Design Ele
