Siemens wins CODLAG frigate contract

Siemens has received an order worth just under €50 million to equip four German Navy Class F125 frigates with propulsion equipment and integrated automation and control systems.

The customer is AGE F125, a joint ventures of Krupp Marine Systems AG and Fr. Lürssen Werft GmbH & Co. KG.

Delivery of the first frigate is scheduled for 2014 and the fourth ship for 2017.

The F125 is the first German Navy frigate to be fitted with a new CODLAG (Combined Diesel Electric and Gas-turbine) electric propulsion system. The advantages of the gas turbine drive, which is designed for high speed, are combined with the benefits of the electrical propulsion unit, which is designed for cruising speed with low noise signatures and high efficiency.

The ships have crews of up to 120 and are designed for deployments of up to two years without having to return to port.

In addition to system engineering and project management, Siemens' scope of supply for each ship includes the electrical propulsion system, consisting of two electric motors (approx. 4.5 MW each) with the associated converters, the electronic control unit and the medium-voltage switchgear. For control and monitoring purposes, an integrated control and automation system for on-board ship equipment (ILASST) will be installed, including a battle damage control system (BDCS) and an on-board training system (OBTS). The complementary solutions of the Sinavy product family from Siemens can be integrated without any interface problems and meet the high requirements placed on surface navy vessels as regards reliability, availability and stability. After delivery, Siemens will be able to provide comprehensive support for the frigates as part of its life-cycle management program.
