Dual-fuel retrofit for Furetank vessel

Caterpillar Marine is conducting its second retrofit of a dual-fuel MaK diesel engine, onboard Furetank Rederi’s 143.9m tanker ‘Fure West’.

The vessel’s MaK M43 C diesel engine will be converted to the seven-cylinder M46 dual-fuel engine, with each cylinder offering 900kW of rated power. Caterpillar will also the complete gas system for the tanker, including bunker stations, to LNG tanks measuring 4.15m x 24m and the vaporiser.

The project, backed by the European Union and developed with the Zero Vision Tool, will mark the second MaK engine dual fuel retrofit. In 2014, Caterpillar successfully completed the dual fuel engine retrofit conversion on the Anthony Veder LNG carrier Coral Anthelia.

Finn Vogler, senior engineer, Caterpillar Marine said. “After our success onboard the Coral Anthelia, we have seen the demand for MaK dual fuel solutions increase substantially.”

The M46 dual-fuel engine designed for electric drive as well as mechanical propulsion systems, has a bore of 460mm and stroke of 610mm. It was specifically designed to allow for the retrofitting of current M43 C engines, while M32 E engines can be retrofitted to the MaK M34 DF dual-fuel platform. The synergies between the two platforms allow Caterpillar to perform in-hull retrofit conversions without having to move the engine block or perform extensive machining.
