MAN HIGH-SPEED HYBRID POWER FOR BS OFFSHORE CSOVs

Dec 14, 2023 | offshore marine news

MAN Energy Solutions’ 175D-MEV methanol-ready high speed engines have been ordered by Ulstein Verft for two battery-hybrid Commissioning Service Operation Vessels (CSOVs) being built for Bernhard Schulte Offshore (BS Offshore).

The propulsion systems will enable carbon-neutral operation. The contract, which includes an option for four additional vessels, is initially for six MAN 12V175D-MEV methanol-ready engines. The vessels are designed to support the offshore wind-energy market, and are planned for delivery in 2025.

The 175D variable-speed gensets will enable the vessels to achieve a significant reduction in fuel consumption and emissions. Each comes with an integrated MAN closed-loop SCR (Selective Catalytic Reduction) system. The MAN 175D gensets feature reduced structural and airborne noise, as well as what is thought to be the lowest lube-oil consumption.

Mads Faerk, Head of Sales, MAN Energy Solutions Norway, said: “As an industry that provides renewable energy, the spotlight is firmly on offshore wind farms regarding carbon emissions and supply-chain sustainability. Decarbonising vessels in the offshore wind sector has great potential and methanol-ready vessels, which can be converted from running on conventional fuels to methanol without the need for a major refit, are an eminently practical way of achieving this.”

Matthias Müller, MD Bernhard Schulte Offshore, said: “The order for the two newbuildings marks a milestone in the development of our offshore fleet. We are committed to innovating in design and technology to promote the decarbonisation of the maritime industry while supporting the energy transformation and offshore wind power supply. MAN’s innovative 175D engine design is notable for its flexible use of various fuel grades, including biofuel, and its suitability for dual-fuel methanol retrofits.”

Compared to conventional fuels, methanol cuts CO2 emissions by up to 95%, NOx by up to 80%, and completely eliminates SOx and particulate matter.

Florian Keiler, Head of High Speed, MAN Energy Solutions, said: “MAN Energy Solutions’ commitment to decarbonisation focuses not only on future fuels but also on the environmental footprint of the engines itself. From optimising lube-oil consumption, maximising oil-change intervals and with best-in-class times between overhaul, the MAN 175D engine achieves the lowest total cost of ownership. We congratulate BS Offshore and Ulstein on this exciting project and are looking forward to working closely with them in executing it. This first order for MAN 175D DNV-approved, fuel-ready engines proves MAN Energy Solutions’ commitment to support the marine industry transition into sustainable fuels.”
