Investing in Canadian facilities and developing propulsion technology has led to propulsion contracts for naval vessels
MAN Energy Solutions’ investment in environmentally sustainable propulsion technology in Canada is paying off as it has secured contracts to supply systems for a new naval fleet.
This propulsion super-group has developed high-speed diesel engines and power generator sets for powerful naval and commercial tugs.
It has produced selective catalytic reduction (SCR) technology for these engines to remove nitrogen oxides and ensure they exceed compliance with IMO’s Tier III Marpol emissions regulations.
MAN Energy Solutions manager for marine sales and projects in Canada Kamen Stoykov says “We continue to commit to Canada and our operations here by investing in our facilities on both the Atlantic and Pacific coasts, and in the process create high-quality jobs.”
MAN has invested in Prince Edward Island-headquartered specialists Aspin Kemp and Associates, which has expertise in power-supply, energy-management and drive-systems.
Mr Stoykov says this investment supports the Canadian Government’s objective to re-establish and grow the nation’s maritime industry and promote exports.
On the technology side, its investment is reducing emissions from MAN engines for newbuilding projects in Canada. “Modern engines will be equipped with the latest environmental protection technology and will comply with the latest environmental regulations,” he says. “They also feature digitally controlled fuel systems for optimal fuel efficiency.”
On the back of this technology development, MAN has secured contracts from the Royal Canadian Navy for Arctic and offshore patrol ships and support vessels.
Naval tug propulsion
Its latest contract award was for propulsion systems and emissions reduction technology for four azimuth stern drive (ASD) tugs for manoeuvring naval ships.
Mr Stoykov says these contract awards are “a vote of trust from the Royal Canadian Navy in our technology and support”. For these naval tugs MAN is partnering with Quebec-based Ocean Industries and Robert Allan under Canada’s National Shipbuilding Strategy to produce four 24-m tugs. These will be situated at the Royal Canadian Navy’s naval bases at Esquimalt, in British Columbia, and Halifax, Nova Scotia.
“We will 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,” says Mr Stoykov.
Ocean Industries has ordered eight of MAN’s 12-cylinder 175D-MM engines and service diesel-generator sets for these four tugs.
For these main diesel engines to be IMO Tier III compliant, Ocean has also contracted MAN to supply SCR systems, each including a urea mixing unit, with injectors, storage tank, self-contained microprocessor-based annunciator units, urea pump module and distributor blocks.
Although engineering and production will be conducted in MAN’s facility in Denmark, its Canadian division will integrate the systems on these tugs. This division will also provide training, testing and support during harbour acceptance and sea-acceptance trials.
These tugs will be built to a Robert Allan RAmparts 2400 design with an expected bollard pull of 60 tonnes and free running speed of 12 knots.
Their hulls will have an 11.25 m beam, 5.40 m draught and they will accommodate six crew.
