This paper describes a marine steam cycle for high steam pressure and low fuel consumption. To achieve good fuel economy even at partial load, the system is designed to operate from maximum manoeuvring rate to "full away" with a floating boiler pressure P sub T. To increase the safety margins of the system and to simplify the feed water control the water level set point is floating proportional to the steam velocity in the superheater steam pipe. The theories of the water level and the boiler pressure behaviour are discussed and evaluated for the control system. Full scale tests at sea trials and dock trials and tests on the small steam turbine plant of the Institut fur Schiffstechnik were run, to prove the theories and the control philosophy.
