DAMEN Naval and Rolls-Royce business unit Power Systems have signed a contract to deliver 16 mtu diesel generator sets, for the four new F126 Frigates for the German Navy.
Although DAMEN and Rolls-Royce, whose business unit Power Systems is based in Friedrichshafen, Germany, have a long-standing cooperation in shipbuilding, this is the first time a contract has been awarded for mtu naval diesel generator sets.
Naval-oriented mtu solutions
According to Managing Director of DAMEN Naval, Hein van Ameijden, the choice was based on Rolls-Royce’s high-end naval-oriented mtu solutions and experience in the high-end naval market.
“We are delighted to announce the news of this contract and the fact we have found another German partner for this prestigious and important project for the Bundeswehr. We look forward to working with Rolls-Royce and its mtu solutions again.”
Efficiency, fuel savings, and maintenance reductions
Due to their variable speed capability, the engines can be operated efficiently, saving fuel and reducing maintenance
The onboard power of each F126 vessel will be provided by four mtu Series 4000 variable speed gensets. These high-performance gensets are the most environmentally friendly naval gensets Rolls-Royce has ever produced: They meet the requirements of the IMO III emissions directive thanks to state-of-the-art mtu selective catalytic reduction (SCR) systems.
Due to their variable speed capability, the engines can be operated efficiently, saving fuel and reducing maintenance. The agreement also includes an Integrated Logistics Support (ILS) package. It is the second F126 contract awarded to Rolls-Royce; earlier this year DAMEN Naval chose the company to supply the automation solutions mtu NautIQ Master and mtu NautIQ Foresight.
Reliability and efficiency
Paul Röck, Director Sales Governmental at Rolls-Royce business unit Power Systems, said, “We are extremely proud to once again be chosen by DAMEN Naval as a partner in this very important and prestigious project."
"Our advanced sustainable solutions for both power and control of the F126 vessels will play a key role in ensuring the frigates’ reliability, efficiency, and operational success.”
The future of high-end naval applications
The advantage of the variable speed generator set is the reduction of fuel consumption at part load operation"
Mr. Van Ameijden adds, “The biggest advantage of the variable speed generator set is the reduction of fuel consumption at part load operation."
"For DAMEN Naval it is the first time that variable speed generator sets are applied on Naval vessels in combination with a DC Grid. We expect that this type of configuration will be the new standard in high-end naval applications.”
Diesel generator sets
With this contract, Rolls-Royce continues its decades-long cooperation with the German Navy. Vessels such as the predecessor frigate classes F124 and F125 as well as the corvettes K130 are equipped with mtu engines and diesel generator sets from Rolls-Royce.
The diesel generator sets will provide electrical power to the F126’s combined diesel-electric and diesel (CODLAD) propulsion system. The CODLAD propulsion system provides a top speed of more than 26 knots. The first diesel generator sets will be delivered in early 2024 to the yard.
Construction contract
In June 2020, the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw) awarded the construction contract for the four F126 frigates to Dutch shipbuilder DAMEN as the general contractor with its sub-contractors Blohm+Voss and Thales.
The ships will be constructed entirely in Germany at shipyards in Wolgast, Kiel, and Hamburg. The first ship will be handed over in Hamburg in 2028. The contract includes an option for two further frigates.
