Tognum to provide propulsion system for U.S. patrol boat

• Single source integrator for the complete propulsion system of U.S. Coast Guard’s first Sentinel Class Cutter
• mtu Series 4000 engines to supply main propulsion
• Use of mtu’s ship automation system Callosum
• Potential for additional 33 vessels (66 engines)

Friedrichshafen/Detroit, 13 May 2009. The propulsion and power solutions specialist Tognum has recently been named as the single source integrator for the complete propulsion system of U.S. Coast Guard’s first Sentinel Class Cutter. This new class of cutter will replace the aging Island Class Cutters that are nearing the end of their service life. Bollinger Shipyards (Lockport, Louisiana, USA), who was named Prime Contractor for this project in September 2008, has contracted directly with MTU Detroit Diesel for the supply and integration of propulsion system components. Delivery of mtu’s first ship set is slated for the beginning of 2010. The order includes an option for 33 additional vessels with mtu propulsion systems.

mtu’s scope of supply includes two 20V 4000 M93L main propulsion engines rated at 4,300 kW (5,766 bhp), along with reduction gears and mtu’s Callosum integrated ship automation system, which continuously monitors and controls all areas and functions of the ship’s mechanical and electrical components and ensures the reliability of the on-board systems.

The 154-foot Sentinel Class Cutter will be capable of speeds in excess of 28 knots and will be built at Bollinger’s Shipyards. It is based on the parent craft concept using a modern hull form, the Damen 4708, which has conducted operations similar to those the Sentinel Class Cutter will perform. The use of this proven design will ensure that the Coast Guard receives new patrol boats capable of performing the required missions as soon as possible. The Sentinel Class Cutter will be capable of deploying independently to conduct U.S. Coast Guard missions such as port, waterway and coastal security; fishery patrols; drug and illegal migrant law enforcement; search and rescue; and national defense operations.

The published acquisition timeline for the optional 33 vessels calls for up to six ship sets ordered per year beginning in 2010. At the peak of production, Bollinger will be delivering a new cutter every eight weeks. The first Sentinel Class Cutter will be delivered to Coast Guard District 7, based in Miami, FL, in January 2011. It will complete a comprehensive operational test and evaluation period and then enter operational service in the Caribbean area of responsibility.
