CCGS Louis St. Laurent Bubbler System Compressor Replacement

The Canadian Coast Guard vessel Louis S St Laurent is Canada’s heaviest ice breaker displacing 14,504 tonnes.  The vessel operates in the Gulf of St. Lawrence in the winter months and in Canada’s high Arctic in the summer and fall.  To assist in ice breaking the vessel utilizes an air bubbler system which blows low pressure air through nozzles in the hull, below the waterline, to help reduce ice friction or blow ice away from the hull.  The bubbler system has multiple zones which are capable of being isolated and can also be used as a bow thruster for precise maneuvering.

The existing bubbler system is made up of two (2) separate units; one port and one starboard.  Both units are comprised of; Compair Reavell Type 9006 CH Compressor, Rated Capacity 6m3/sec, Press 1.61 Bar, Blower Speed 11800 rpm coupled through a reduction gearbox to a 6600vac electric motor.  Compressors are controlled locally in the bubbler compartment and remotely from port and starboard bridge consoles.  
 
The existing units and control systems are in excess of 25 years old, with reliability and supportability becoming an issue. The Coast Guard is seeking a suitable system that will be used to replace the existing arrangement in its entirety. Systems will be required to meet the minimum requirements listed in the Statement of Work, and will be evaluated accordingly.
