MTU’s Series 4000 Engine for French Navy
MTU Friedrichshafen announced it has won a contract to supply the diesel electric propulsion systems for eight French frigates from the FREMM program (Frégates Européennes Multimissions). Prime contractor for the vessels is Armaris, a joint subsidiary of the defense concerns DCN and Thales.
Each vessel will feature four 16-cylinder MTU Series 4000 diesel engines for the diesel electric propulsion and the onboard power generation systems. Each engine delivers 2200 kW. A gas turbine will be included in the propulsion system for higher speeds. The frigates have an overall length of more than 140 m and a displacement of 6000 tons and can achieve a top speed of approximately 27 knots with gas turbines and around 16 knots with diesel electric propulsion. Delivery of the first unit is scheduled for 2008.
MTU confirmed that its first contributions to the program were made at the vessel design stage with solutions for the horizontal exhaust outlet system. Because the outlet is located just above the waterline, the diesel unit has to be able to withstand extremely high, short-term exhaust backpressures. Double resilient mounts and acoustic enclosures mean that these diesel electric propulsion units achieve uniquely low acoustic signatures whilst their low weight and shockproof mountings provide an extremely robust design.
