MAN Energy Solutions is to supply the main propulsion engines for two new Robert Allan Ltd. designed ice-breaking ASD tugs that will be operated by Svitzer in the Scandanavian region.
Each vessel, rated with 60 tonnes of 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 by MAN Energy Solutions directly from its purpose-built, state-of-the-art production facility in Frederikshavn, Denmark to Turkish-based shipbuilder Med Marine. The vessels are due to enter service by the end-2020.
“We are happy to have the new MAN 175D high-speed engine in our two newbuildings,” said Esben Grundtvig, Head of Group Newbuilding, Svitzer. “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.”
“Med Marine is proud to be building the first series of Tundra 3000 design MED-A3060-ICE class tugboats for Svitzer,” said Muhammet Gokhan, Business Development Manager, Med Marine. “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 harbor operations and their strict environmental requirements.”
PREPARED FOR TIER III UPGRADE
Though the engines will be installed with an IMO Tier II NOx emissions compliance certificate, both vessels’ engine rooms will be designed in such a way that additional MAN-supplied Selective Catalytic Reduction (SCR) equipment can be installed at a later date, raising the vessels compliance to IMO Tier III emissions standard. Key factors that enable this are the compact and modular construction of the MAN Energy Solutions’ SCR components. The MAN175D engine hardware will require no subsequent modification, making retro-upgrading easily achievable.
Another significant factor considered as important to the success of this installation is the overall life-cycle costs of these modern diesel engines. MAN Energy Solutions believes that the MAN 175D is amongst the most fuel-efficient, high-speed engine available for marine propulsion. Coupled with this, the low cost of maintenance during the operational lifetime of the engines makes them a very competitive option for tug owners and operators to consider.
ABOUT THE MAN 175D ENGINE
MAN Energy Solutions has developed the MAN 175D engine range to supplement and complete its product portfolio in the maritime sector. The 12, 16 & 20-cylinder variants of the engine are available with outputs ranging from 1,500 to 4,000 kW and are optimized for propelling ferries, offshore supply vessels, tug boats and other working vessels. Other market areas, such as superyachts and naval marine applications are also served by additional, specialist model versions. The MAN 175D is also an extremely eco-friendly engine, being designed from the outset with compliance to the latest, as well as future, exhaust-gas-emission requirements and utilizing a very compact and flexible SCR system, which enables vessel designers to optimize space on board to the maximum.
