USCG selects MAN 28/33D STC engines for OPC programme


The US Coast Guard’s (USCG) new Offshore Patrol Cutter (OPC) programme will be equipped with MAN Diesel & Turbo’s 28/33D STC engines as the main propulsion.

The programme will replace the 13 ‘Famous’ class and 14 ‘Reliance’ class cutter vessels.

MAN Diesel & Turbo Four-Stroke Marine head Lex Nijsen said: “We are very pleased to have won this major order within such a key, domestic market. It’s a breakthrough for us as this is the first time that the USCG has ordered MAN 28/33D STC engines.

“Indeed, the engine’s sequential turbocharging (STC) concept continues to make inroads into the Navy and Governmental segments where its inherent power characteristics offer a manoeuvrability that matches such demanding applications well.

“This success was achieved in great part through close cooperation with our longstanding partner and licensee, Fairbanks Morse Engine (FME).”

Each of the new 360ft cutters will be powered by two MAN 16V28/33D STC engines.

FME will produce and test the engines at its Beloit, Wisconsin plant, while the OPC ships will be designed and built by Eastern Shipbuilding Group.

Initially, the USCG placed an order for nine ships with plans to ultimately produce 25. The first ship of the class is expected to be delivered in 2021.

The MAN 28/33D STC engines generate compact power and are fully compliant with current environmental standards, producing NOx emissions that fulfil IMO Tier IIand EPA Tier 2 regulations.

Further, the maintenance costs and servicing downtime of MAN 28/33D STC engines are kept low due to high engine availability.

MAN Diesel & Turbo is a German-based company that manufactures large-bore diesel engines and turbomachinery for marine and stationary applications.
