ECONOMIC CONSIDERATION OF CONTROLLABLE PITCH PROPELLERS WITH DIESEL MAIN PROPULSION

This study is concerned with a performance and economic comparison of a controllable pitch propeller installation vs a fixed pitch propeller installation, both with geared diesel engine drive. It is based on a hypothetical 25,000 dwt tanker, operating mainly in the Caribbean/Gulf of Mexico area, and carrying cargo one way and returning in ballast. Factors weighted in detail are--capital acquisition cost differential, operating costs, intangible gains, reliability, and life cycle cost. It is concluded that any ship study envisioning the use of a diesel prime mover should incorporate the use of a controllable pitch propeller.
