Kongsberg Maritime selected by Austal USA to supply propulsion system to the latest ship in United States Coast Guard

Kongsberg Maritime has been selected by Austal USA to supply its Promas propulsion system to the latest ship in the United States Coast Guard’s new Offshore Patrol Cutter (OPC) Heritage Class programme.

This initial contract is to supply Kongsberg Maritime equipment for the fifth ship, Coast Guard Cutter Pickering, which is the first to be built by Austal USA at their yard in Mobile, Alabama.

Notably, the Coast Guard’s new OPC programme represents a significant investment in maritime capability and is expected to run up to 25 ships.

Further, the new vessels will replace the Coast Guard’s medium endurance cutters and meet the need for long-term offshore capability to maintain current and future mission effectiveness.

Noteworthy, Promas combines rudder and controllable pitch propeller into one propulsion system which optimises the hydrodynamic properties of the ship and delivers increased efficiency and thrust while using less energy.

For the OPC, as well as twin Promas, Kongsberg Maritime is contracted to supply steering gear, rudders, fin stabilisers and tunnel thrusters.

The new 109-metre OPC vessels will provide long range patrol capability, with a range of 9,050 nautical miles at 14 knots.

The Promas systems typically deliver efficiency savings of around 6%, so vessels are able to extend their range, something which can be crucial on longer missions.

The OPC vessels will be able to provide long range patrol capability.

At 360 feet long, they will have a displacement of 3,700 long tons, maximum speed of 22.2 knots, and a range of 9,050 nautical miles at 14 knots.
