MTU ENGINES FOR BRAZILIAN HYBRID TUGS

MTU ENGINES FOR BRAZILIAN HYBRID TUGS

Thursday, November 4, 2021 

Rolls-Royce has secured a significant contract to supply eight of its mtu 16V 4000 M65L engines for four 80t bollard pull tugboats to be built by Detroit Brasil, and operated by Starnav Servicos Maritimos.

The new tugs will feature a hybrid propulsion system, combining the mtu engines and mtu Blue Vision New Generation (BVNG) monitoring system with Z-drive thrusters, hybrid components and controls from Schottel.

While Rolls-Royce has supplied mtu Series 4000 engines to Detroit Brasil for several vessel projects in the past, this marks the first time Rolls-Royce will be supplying engines for 80t bollard pull tugboats to the company and the first time that the high performance mtu 16V 4000 M65L engines which deliver 2560kW at 1,800 rpm will be used in Latin America. Once the new tugs enter into service, Starnav Serviços Marítimos will have a total of 96 mtu Series 4000 engines in its fleet of harbour tugs and offshore vessels.

Maxwell Oliveira, GM Detroit Brasil Shipyard, said: “The hybrid system featured on the new tugs will allow for the ships’ thrusters and one of the two main engines to be connected for all light operation activities when full power is not required, reducing the operating hours for the main engines, leading to lower overall maintenance costs, better fuel consumption and lower emissions compared to a traditional configuration. When full propulsion power is needed, the connection between the two thrusters is disengaged and each engine is engaged to each thruster, reverting to a traditional, direct-drive propulsion system. The performance characteristics of the mtu 16V 4000 M65L and its wide performance map allow for this type of hybrid propulsion concept while keeping a considerable level of available reserve power on demand.”

Christof von Bank, Marine Sales Director Americas, Rolls-Royce Power Systems, said: “This order is an important milestone 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 to Latin America for the first time. Further, this contract will reinforce our 20% share in the Brazilian tug boat market with mtu engines, a position we’ve earned over the past decade since installing our first Series 4000 in a tug in 2010.”

“The mtu 16V 4000 M65L engines offer the best engine performance for the hybrid propulsion concept being utilised in our new tugs,” said Carlos Eduardo Pereira, CEO Starnav Serviços Marítimos. “Having accumulated 2.5m hours of operation with mtu engines in several of our harbour tugs and platform supply vessels operated over the years, mtu engines were a reliable choice for these new ships.”

The engines will be delivered in phases, with two delivered in August 2022, two more in October, and two ship-sets consisting of two engines each for delivery in December.
