Rolls-Royce will be providing propulsion gear for the U.S. Coast Guard’s new offshore patrol cutters (OPC), the company press release said.
Eastern Shipbuilding Group, the prime contractor on the program, selected Rolls-Royce equipment for the USCG OPC fleet’s first nine vessels, with an option to add two more.
Rolls-Royce will supply the USCG OPC fleet’s controllable pitch propellers (CPP), shaft lines and Promas rudders, which offer increased propulsive efficiency and improved maneuverability.
The Promas rudder combined with the water soluble polyalkylene glycol lubricant used in the CPP system delivers an efficient and environmentally friendly propulsion solution. Rolls-Royce will also supply bow thrusters, steering gear, fin stabilizers and MTU marine generator sets.
Four EPA Tier 3 compliant MTU 12-cylinder Series 4000 (1000kW) generator sets will provide each vessel with electrical and loiter propulsion power. The units are Naval Vessel Rules (NVR) certified by the American Bureau of Shipping (ABS).
The new vessels will replace the USCG’s fleet of Medium Endurance Cutters, providing a capability bridge between the National Security Cutter (NSC) fleet, which is equipped with Rolls-Royce controllable pitch propellers and bow thrusters, and the Fast Response Cutter (FRC) fleet, which operates closer to shore.
