Caterpillar Marine Performing Dual Fuel Marine Engine Retrofit

Caterpillar Marine is currently underway on a dual fuel engine retrofit conversion onboard the 472 foot Fure West tanker, owned by Furetank Rederi A/B. The MaK M 43 C diesel engine onboard the tanker will be retrofitted in hull to the 7 cylinder M 46 dual fuel platform. Additionally, Caterpillar is also supplying the complete gas system for the tanker, including bunker stations, two LNG tanks and the vaporizer.

This project, backed by the European Union, will mark the second MaK engine dual fuel retrofit. In 2014, Caterpillar successfully completed the dual fuel engine retrofit conversion on the Anthony Veder Coral Anthelia LNG carrier.

The M 46 dual fuel engine was designed for electric drive propulsion systems as well as mechanical propulsion systems. Although designed for unlimited operation on LNG, marine diesel oil and heavy fuel oil, the M 46 DF will reach optimal efficiency in gas mode. The M 46 DF was strategically engineered to allow for the retrofitting of current M 43 C engines. Additionally, existing M 32 E engines can be retrofitted to the MaK M 34 DF dual fuel platform. As a result of the synergies between the two platforms, Caterpillar can perform in hull retrofit conversions without having to move the engine block or perform extensive machining.
