F219 Sachsen, German Air Defence Frigate
Moored at Kvillepiren in the centre of Gothenburg on 9 May 2010.
This is the first of its class, FGS Sachsen (F219), built at the Blohm and Voss shipyard in Hamburg, and commissioned in November 2004.
These F124 ships are equipped with a combined diesel and gas propulsion system, CODAG. The two operating shafts work independently. The diesel engines are installed in a non-walkable sound-proof capsule. The shafts drive two five-bladed controllable pitch propellers.
In diesel mode, one of the diesel engines (type MTU 20V 1163 TB93) is operated via two main gearboxes and one cross-connection gearbox. The peak performance of the diesel provides 7,400 kW at 1,350rpm.
The operating range is 4,000 nm at a cruising speed of 18kt in diesel mode.
In gas turbine mode, the gas turbine (model GE 7 LM2500 PF/MLG) provides 23,500 kW and 3,600 rpm, operating two main gearboxes and the cross-connection gearbox.
In combined diesel and gas propulsion mode (CODAG-mode), both diesel engines and the gas turbine engine are operated. The maximum speed of the ship is 29kt.
The Sachsen class of frigates is described in detail on the Naval Technology web site.
