MTU 4000 Engines to Power Harbor Tugs

Four Robert Allen/ Rastar 2900 SX terminal tugs from Sanmar will be used in the fleet in the Tanger-Med Port in Morocco, operated by the Danish towage company Svitzer as of 2018. The tugs will each be fitted with two 16V 4000 M73L MTU engines. (Photo: Rolls-Royce)

Rolls-Royce and Sanmar Shipyards in Turkey have signed a contract for the delivery of eight MTU Series 4000 engines for four new terminal tugs, including an option for a further four engines. The tugs will each be fitted with two 16V 4000 M73L MTU engines, each delivering an output of 2,700 kW (at 1,850 rpm). The MTU brand is part of Rolls-Royce Power Systems.
 
Ali Gürün, Projects Director of Sanmar Shipyards, commented, “We were impressed by MTU’s technical support, the service and the reliability of the MTU engines, which is why we will also be equipping our new Robert Allen/ Rastar 2900sx tugs with MTU engines.”

Sanmar and MTU have been working closely together since 2009.
 
Knut Müller, Head of the Marine and Government Business Division at MTU, said, “This is the first time high-speed engines are being used to power harbour tugs in this power class. To date, it has only been possible to use medium-speed engines for harbour tugs with a bollard pull of over 85 tonnes.”

The speed of the engine has been reduced to 1,850 rpm specifically for this application in order to provide the Shipyards with direct control of the propeller without an intermediate gearbox.
 
The Robert Allen/ Rastar 2900 SX terminal tugs, with a length of just under 30 meters, will be added to the fleet operated by the Danish towage company Svitzer as of 2018. The powerful tugs are to be used in the Tanger-Med Port in Morocco, the operators of which have now signed a 20-year contract with Svitzer for terminal towage services. The port is located on the northwest coast of Africa, close to the entrance to the Mediterranean on the Strait of Gibraltar, and is the second busiest container port on the African continent.
 
MTU and Sanmar have signed an additional contract for the delivery of four 16V 4000 M63 engines, each delivering 2,000 kW of power for two tugs with a 70-metric-ton bollard pull. These new contracts now bring the number of tugs built by Sanmar to date and fitted with MTU engines to 16. Half of the tug types currently available from Sanmar Shipyards are fitted with MTU engines.
