MAN 35/44DF CD Genset Cuts Methane Slip by 85%

The MAN 35/44DF CD auxiliary engine

MAN Energy Solutions has introduced its latest engine, an auxiliary MAN 35/44DF CD type. Developed in cooperation with STX Engine and solely for production by MAN licensees, the new engine is particularly aimed at container and LNG carrier applications.

The 35/44DF CD reduces methane slip by up to 85% compared with market standards.

The genset was developed with the aim of cutting down CAPEX and OPEX costs and for being future-proof over the coming decades. It is based on the mature MAN 35/44DF CR and MAN 32/44CR engines – proven in many applications with millions of running hours – that form the basis for its operational safety and low maintenance requirements.

Features include full digitalisation and connectivity with cyber security; compact footprint with multiple layout options for engine-room flexibility; highest power output in segment with 560 kW/cylinder; and leading to fewer cylinders or even engines for same power output per vessel.

First deliveries are expected by mid-2024, with the first unit in commercial operation from 2025. Alexander Knafl, Head of R&D Engineering, Four-Stroke, MAN Energy Solutions, says the genset will be ready for dual-fuel methanol operation by 2026.

Sephardim Koblenz, Head of Licensing, MAN Energy Solutions, said: “We specifically developed the MAN 35/44DF CD in close collaboration with STX Engine to optimise the requirements of an auxiliary engine. Among other characteristics, both shipyards and shipowners greatly appreciate auxiliary engines that are easily installed and maintained, while reliability and cost-optimisation are also key.”
