Rolls-Royce to supply mtu engines for four tugs in Brazil
Rolls-Royce has been awarded a major contract to supply eight of its 16V 4000 M65L mtu engines for four 80 ton bollard traction tugs to be built by Detroit Brasil, Ltda. and operated by Starnav Servicos Maritimos Ltda. The new tugs will feature a hybrid propulsion system, combining mtu engines and the Blue Vision New Generation (BVNG) mtu monitoring system with Z-drive thrusters, hybrid components and controls from Schottel, a manufacturer of propulsion systems and steering for ships and offshore applications. .
While Rolls-Royce has supplied 4000 series mtu engines to Detroit Brasil for several vessel projects in the past, this is the first time that Rolls-Royce will supply engines for 80 ton tugs to the company and the first The High performance mtu 16V 4000 M65L engines that deliver 2,560 kW at 1,800 rpm will be used in Latin America. Once the new tugs are in service, Starnav ServiÃ§os MarÃtimos Ltda. will operate a total of 96 mtu 4000 series engines in its fleet of harbor tugs and offshore vessels.
âThe hybrid system featured on the new tugs will allow the ship’s thrusters and one of the two main engines to be connected for all light-duty activities when full power is not required, reducing hours. operation of the main engines, resulting in lower overall maintenance costs, better fuel consumption and reduced emissions compared to a traditional configuration, âsaid Maxwell Oliveira, general manager of the Detroit Brasil shipyard.
âWhen full propulsive power is needed, the connection between the two thrusters is disengaged and each motor is engaged on each thruster, reverting to a traditional direct drive propulsion system. The performance characteristics of the mtu 16V 4000 M65L and its large performance map allow this type of hybrid propulsion concept while maintaining a considerable level of power reserve available on demand, âsaid Oliveira.
“This order is an important step in the launch of the next generation of mtu 4000 series engines, as the 16V 4000 M65L engine is currently the most powerful version of the new series and is being supplied for the first time in Latin America” said Christof von Bank, Sales Director, Marine, Americas of the Rolls-Royce Power Systems business unit. âIn addition, this contract will strengthen our 20% share of the Brazilian mtu-powered tug market, a position we have gained over the past decade since installing our first 4000 series in a tug in 2010. “
âThe 16V 4000 M65L mtu engines provide the best engine performance for the hybrid propulsion concept used in our new tugs,â said Carlos Eduardo Pereira, CEO of Starnav ServiÃ§os MarÃtimos Ltda. “Having accumulated 2.5 million mtu engine hours of operation in several of our harbor tugs and platform supply vessels operated over the years, mtu engines were a reliable choice for these new vessels.”
The mtu engines will be delivered in multiple phases, with two delivered in August, two more in October and two sets of ships consisting of two engines each for delivery in December.
