Video shows a project developed by MAN Diesel & Turbo and Odfjell whose results have been verified by Norwegian Marine Technology Research Institute and Rightship.
The Norwegian Odfjell is in close cooperation with MAN Diesel & Turbo to upgrade the propulsion system on 19 of the vessels in their fleet. The propulsion system is upgraded with a combination of the highly efficient MAN Alpha Kappel propeller concept and the MAN Alpha rudder bulb & fairing cone concept. Engine power limitation (EPL) and a change of the gear ratio of the power take out (PTO) for the shaft generator are also part of the upgrade – all perfectly match together by MAN Diesel & Turbo and optimized for the operation profile of the vessels.
The outcome is fuel oil savings well above 20%. As a result of the improved energy efficiency the vessels have moved from class D in the Rightship GHG environmental energy rating to class A – the highest possible rating.
