This paper describes the details of realization and the test results of a new 1000KW - 2500RPM - 21 liter Hyperbar engine developped and constructed for the propulsion of 60 tons coast guard ships, having two fixed pitch propellers.
The torque characteristics of these engines ensure the ship to be propelled between 28 and 6 knots under continuous operation without overheating, smoke and fouling, and without using any auxiliary propulsion unit for slow cruising speed.
The performances, including fuel consumption are reported under various operating conditions.
