INCORPORATING

MAN HIGH-SPEED ENGINES FOR ICEBREAKING TUGS

Tuesday, November 19, 2019 

MAN Energy Solutions has won a contract to supply main propulsion for two new ice-breaking ASD tugs, to be operated by Svitzer in the Scandinavian region.

Each vessel, rated for 60t bollard pull, will be powered by two MAN 12V175D MM, IMO Tier II engines, each rated at 2,040 kWm at 1,800 rpm. All four engines will be supplied from the MAN Energy Solutions facility in Frederikshavn, Denmark to Turkish-based Med Marine. The vessels are due to enter service by end 2020.

Esben Grundtvig, Head of Group Newbuilding, Svitzer said: “We are happy to have the new MAN 175D high-speed engine in our two newbuildings. We are confident that we will have the same high quality as usual from two-stroke and medium-speed engines from MAN. It is important to Svitzer to work closely with key suppliers like MAN Energy Solution to honour our client’s requirements for bollard pull from 60 to 90-plus tons and 1,800-3,000 kW, both with high-speed and medium-speed engines.”

Muhammet Gokhan, Business Development Manager, Med Marine said: “Med Marine is proud to be building the first series of Tundra 3000 design MED-A3060-ICE class tugboats for Svitzer. In addition to combining Med Marine and Robert Allan’s experience, we are also happy to cooperate with MAN in this project. Equipping the tug with MAN 175D high-speed engines will make this vessel excellently suited for operation with very quick acceleration.”

Lex Nijsen, Head of Four-Stroke Marine Sales, MAN Energy Solutions, said: “Tugs form a special segment with many hours of standby and sudden demands for high loads. This is another, excellent reference for the 175D that adeptly handles the complexity of harbour operations and their strict environmental requirements.”

The engines, as installed, will carry an IMO Tier II NOx emissions compliance certificate. The engine rooms are arranged to enable MAN SCR equipment to be retrofitted for Tier III compliance. MAN Energy Solutions’ SCR components and the MAN175D engine hardware are designed to easily achieve this upgrade.

Another significant factor is the overall life-cycle costs of the MAN 175D, said to be among the most fuel-efficient high-speed engines available for marine propulsion. Coupled with this, the low cost of maintenance during the operational lifetime of the engines makes them a competitive option for tug owners and operators.
