MAN ES to provide propulsion systems for Canadian Coast Guard’s AOPSs

German manufacturer MAN Energy Solutions (MAN ES) has received a contract to provide propulsion systems for two Arctic offshore patrol ships (AOPSs) for the Canadian Coast Guard.

MAN Energy Solutions will deliver the engines, shafts and propellers for the AOPS’ integrated diesel-electric propulsion systems, as well as complete integrated logistics services (ILS) documentation. 

Each vessel will feature 4 × MAN 6L32/44CR engines, with each engine delivering 3,600 KW and utilizing common-rail (CR) electronic injection, high-efficiency turbochargers, electronic hardware and variable valve timing.

The company will also provide a selective catalytic reduction system with each engine. In combination with the SCR system, the common-rail injection system is expected to optimized each engine’s fuel consumption and emissions, resulting in IMO Tier III compliancy without sacrificing engine efficiency. This ultimately could reduce each ship’s carbon footprint to a minimum, a crucial factor when considering the fragile Arctic environment for which the ships are destined. 

Finally, MAN Energy Solutions will deliver 2 × MAN Alpha-branded five-bladed, bolted propellers that meet PC5 rules and which can even be exchanged underwater. These cater for higher cavitation inception speeds, possible shock impacts, and mission-critical conditions requiring additional redundancy, silent operation with minimal hydro-acoustic signatures, and suppressed underwater-radiated noise, the company highlighted.

The order is part of the Canadian government’s National Shipbuilding Strategy (NSS).

In 2015 MAN Energy Solutions won the order for six identical vessels for the Royal Canadian Navy. Irving Shipbuilding will construct the vessels in Halifax, Canada. The local MAN Canada PrimeServ organizations in Halifax and Vancouver will provide service support to the Canadian Coast Guard to operate these vessels throughout their operational life.

“It’s always encouraging to win such a high-profile order and, as a repeat order, the trust that it represents in our solution is significant. The MAN 32/44CR engine is optimal for providing the kind of power and reliability required by the extreme conditions that each Arctic/Offshore Patrol Ship must endure, while its Tier III compliancy is also critical in such a sensitive operating environment. This new order fits well with our company’s desire to supply complete propulsion packs,” Daniel Eberhardt, Sales Manager Navy, Four-Stroke Marine, MAN Energy Solutions, said.
