MAN Dual Fuel Marine Engine

THE SUSTAINABLE HYDROGEN PROPULSION FOR WORK BOATS

With the MAN D2862 Dual Fuel Engine you can reduce the emissions while at the same time benefiting from maximum operating reliability you are used to from MAN diesel engines. The MAN D2862 Dual Fuel engine is a joint project with CMB/CMB. TECH and Windcat Workboats.

MAN D2862 Dual Fuel

More Hydrogen. Less Diesel. Less CO2 Emissions.

The base of the MAN D2862 Dual Fuel engine is a proven V12 marine diesel engine. In that, hydrogen is introduced into the charge air via an adapter and is added to the combustion cycle. The combustion process is thereby started according to the diesel principle, which requires the injection of approx. 5% of diesel fuel. The diesel fuel common rail injection parameters have been optimised here for dual fuel operation.

MAN Engines has long-standing experience in the development of fuel-saving and reliable diesel engines, including for work boats. Building on this experience, the best consumption values in dual fuel operation could be achieved and ensure the same operating behaviour as displayed by diesel operation at full load.

What’s special about the technology of MAN Engines is that we use a conventional diesel engine, which doesn’t need to be optimised for hydrogen.

Customer benefits

  • An average of approx. 50%, and even up to 80% as a peak value less CO2 tailpipe emissions compared with the diesel engine
  • Just as powerful and reliable as the diesel engine
  • Operation either as a pure diesel drive or as a dual-fuel engine
  • Uninterrupted operation even when the hydrogen tank is empty
  • Ensuring availability, driving comfort and operational safety at the well-known high level of a conventional diesel drive

THE HYDROCAT 48 PROJECT

The Hydrocat is the first hydrogen-powered CTV whose technology reduces more than 50% of its traditional fuel usage. Its propulsion: two MAN D2862 dual-fuel engines.

The Hydrocat is a further “green development” based on an already very fuel efficient and high performing Windcat MK3.5 hull design. The Hydrocat is a vessel that excels in vessel performance, safety and comfort. In addition, noise levels have been reduced to extremely low values (65 dB) at maximum speed for extra comfort by separating the passenger area from the main structure. The Hydrocat is numbered 48 because it follows on from the series of vessels of the Windcat MK3.5.

Only the hydrogen injection system has been retrofitted. The output, operating behaviour and other characteristics of the diesel engine remain unchanged. ©Windcat Workboats

The partners

CMB (Compagnie Maritime Belge) is a diversified shipping and logistics group based in Antwerp, Belgium. CMB owns and operates 147 seagoing vessels in dry bulk (Bocimar), container transport (Delphis), chemical tankers (Bochem) and crew transfer vessels (Windcat). CMB is also active in cleantech (CMB. TECH) and real estate (MCA Facilities, Maritime Campus Antwerp). CMB has offices in Tokyo, Singapore, Hong Kong, Germany (Hamburg), UK (Lowestoft and Brentwood) and The Netherlands (Amsterdam). CMB.TECH is a cleantech company that builds, owns, operates and designs large marine and industrial applications that run on hydrogen and ammonia. CMB.TECH also offers hydrogen and ammonia fuel to its customers, either through its own production or by sourcing it from third party producers.

Windcat Workboats owns and operates a growing fleet of over 48 offshore crew transfer vessels, mainly in the European offshore wind sector, but also in the oil and gas industry and outside Europe. The vessels are designed and built by ourselves and, as such, include over 19 years of experience in the field. The vessel’s layout and propulsion is optimised to transfer personnel offshore in a safe and comfortable environment.
