Box 5158 Newark, N.J. 07105 "PRIDE IN PERFORMANCE" rating the EMD 20-cylinder diesel engine, has successfully completed the Det norske Veritas (DnV) 15 degree permanent inclination test. The approval of DnV applies to EMD's com- plete line of 8, 12, 16 and 20-cylinder naturally aspirated and turbocharged diesel engines, as applied to the marine drilling power unit config- uration. The tests were conducted with the EMD 20F9B engine and consisted of 12 hours of run- ning time at full-rated horsepower/speed. Wit- nessing the test were officials from Det norske Veritas, American Bureau of Shipping and Lloyd's Register of Shipping. The test is manda- tory, at present, for generating sets used on off- shore rigs and platforms requiring DnV certifi- cation. The means to achieve the DnV 15-degree inclination requirement were based by Electro- Motive on a "total system" design approach; i.e. engine, generator, modular accessory rack, and external lube oil tank mounted on a common base and interfaced, as necessary to provide a power "unit" capable of full-rated output. During the 12-hour test the engine lube oil pressures and temperatures remained constant. Normal engine start was achieved prior to initia- tion of each six-hour test and clear exhaust CENTRIFUGE SERVICES BOWL REPAIR • BALANCE • REPLACEMENT PARTS EQUIPMENT ENGINEERING, INC. 757 EAST MURRY STREET (3171783-5496 INDIANAPOLIS.

Cooling water pressure and temperature re- mained constant during the test. After the test was completed, a complete airbox inspection was performed. This included an in-place exam- ination of all pistons and liners. The crankshaft thrust bearing, the crankshaft upper and lower main bearings, the connecting rod upper and lower bearings, the turbocharger compressor thrust bearing, the turbine bearing, and planeta- ry bearings showed only normal wear in polish- ing upon inspection.
