Propulsion has been selected for a series of Polar-class emergency response and security vessels being built in Canada
Seaspan Shipyards is building six multipurpose ice-breaking vessels designed by Aker Arctic for the Canadian Coast Guard as part of the national shipbuilding strategy to operate in Canadian waters.
It has contracted Steerprop to provide Polar Class 4 (PC 4) propulsion packages for these newbuild vessels, including two contra-rotating propulsors (CRP) for main propulsion and two tunnel thrusters for auxiliary manoeuvring for each ship.
These will be designed, engineered and manufactured to meet the stringent operational demands of the vessels in Arctic waters and along the seaboards of Canada.
CRP units facilitate efficient ice management, which is important for maintaining safe navigation channels and responding to emergencies in icy conditions, while reducing energy consumption and emissions.
