Rolls-Royce has secured new order for the delivery of the latest 16-cylinder engines, which are set to be installed on-board the French Navy’s five new medium-sized Frégates de Taille Intermédiaire (FTI) frigates.

The contract was awarded by French shipbuilder Naval Group and will involve the supply of 20 units of Rolls-Royce’s MTU 16V 8000 M91L engines, which will be capable of delivering up to 8,000kW of mechanical power each.

The new engines are slated to be delivered between the end of 2020 and 2027, while installation on-board the naval vessels will begin from 2023 onwards.

“We are proud to have succeeded in convincing Naval Group and the French Navy of the merits of our new engine.”

Rolls-Royce’s 16-cylinder MTU engines have the capability to provide high power density and low environmental impact, while maintaining low overall operating costs.

MTU Marine & Government Business head Knut Müller said: “We are proud to have succeeded in convincing Naval Group and the French Navy of the merits of our new engine, and to have the opportunity of powering these leading-edge vessels with their all-new design.”

Each of the French Navy’s five FTI frigates will be powered by four 16V 8000 engines forming a combined diesel-and-diesel (CODAD) propulsion system, with two diesel engines connected to each of the vessel’s dual prop shafts.

The propulsion system is expected to generate a total energy output of 32MW, providing the 122m-long vessels with speeds of up to 27k and range of up to 5,000nm.

In addition, the frigates are set to feature a displacement of 4,250 metric tonnes (mt) each and will be capable of performing a wide variety of roles, including intercepting threats posed by other surface vessels, submarines and aircraft.

The five new FTIs are slated to enter service with the French Navy by 2030, joining the navy’s existing fleet of eight, slightly larger Aquitaine-class FREMM multi-mission frigates.
