Quebec-based Ocean Industries Inc. has ordered eight MAN 12V175D-MM, IMO Tier III-compliant engines to power four 24-meter ASD tugs on order the Royal Canadian Navy.

Under the contract, MAN Energy Solutions will also provide SCR (Selective Catalytic Reduction) technology for the engines, facilitating Tier III compliance, along with ship service diesel-generator sets.

Work on these components will take place at MAN’s facility in Denmark, while its Canadian division will integrate the systems and additionally provide training, testing and support during harbor-acceptance and sea-acceptance trials.

Known as the Naval Large Tug (NLT) project, the new IMO Tier III vessels are based on a proven Robert Allan Ltd. RAmparts 2400 design and are being built under Canada’s National Shipbuilding Strategy

Kamen Stoykov, Marine Sales & Projects Manager, MAN Energy Solutions, Canada, said: “MAN is excited to partner with the Ocean Group under Canada’s National Shipbuilding Strategy to provide our state-of-the-art MAN 175D high-speed propulsion engines and power generation for the Royal Canadian Navy’s new Naval Large Tugboats. These modern engines will be equipped with the latest environmental protection technology from MAN and will comply with the latest environmental regulations. They also feature digitally-controlled fuel systems for optimal fuel efficiency.”

Stoykov continued: “MAN Energy Solutions views this contract – along with recent Arctic and Offshore Patrol Ship (AOPS) and Joint Support Ship (JSS) orders – as a vote of trust from the Royal Canadian Navy in our technology and support. Accordingly, we continue our commitment to Canada and our operations here by continuing to invest in our facilities on both the Atlantic and Pacific coasts, in the process creating high-quality jobs. MAN looks forward to more opportunities to work with the Royal Canadian Navy in the future.”

MAN has already invested in Aspin Kemp and Associates – the power-supply, energy-management and drive-systems specialist from Prince Edward Island (PEI) – thus supporting the Government of Canada’s objective to re-establish and grow the Canadian maritime industry and provide access to world markets for Canadian companies.
