IntroductionThe number of vessels equipped with controllable pitch propellers (CPP)has steadily grown in recent decades. Today fixed pitch propellers (FPP) areused for vessels where simplicity and operation at sea are dominant. Thisincludes tankers, bulk carriers and vessels are normally equipped with 2-stroke diesel are also a number of vessels where the application of fixed pitchpropellers in combination with a 4-stroke engine and a gearbox hasbecome the standard. Examples of such vessels are container feeders,offshore vessels, dredgers and requirements include the need to use maximum engine power inall operating conditions, along with good manoeuvring capability and fullyautomatic control systems.

discussed with the yard and the owner. The design conditions and off-design modes are carefully agreed and registered. This is especially important for dredgers, passenger and RoPax vessels.
