The Navy went looking to Purchase 4 new Large tugs to replace the Glen and Fire Class Boats in 2012. That procurement hasn’t gone anywhere, and the government is now looking at the price and availability  to charter tugs for 5 years, with options on renewal for up to 20 additional years. They are looking at four tugs; Two for the East Coast; and Two for the West Coast.

The Stated requirements are:

•Twin engine/propulsion plant capable of delivering an approximate bollard pull of  40 tons or an equivalent total power of 4,000 BHP;
•Firefighting capability (FiFi 1);
•Full speed of at least 12 knots (fully loaded);
•Draft not to exceed 6 meters;
•Vessels not to exceed 5 years of age at the start of the contract.
•Preferred length overall not to exceed 33 metres;
•The vessels will be operated by a civilian crew holding Transport Canada certification;
•The tugs must have a Transport Canada Certificate of Registration;
•The vessels must meet regulatory requirements to operate in Canada and be in full compliance with the Canada Shipping Act; and
•Daily in harbour operations consisting of hot or cold moves of existing and future warships up to 25,000 tons displacement;
•Assisting in closing harbour gates, delivering supplies or fresh water, buoy operations and other routine harbour tasks

Interestingly, they are looking at both Bareboat Charter, or as a Time Charter. In a bareboat charter, the Navy would crew the vessels and only pay for using the Hardware (Much like leasing a car) the other option would be to provide a fully crewed tug, available on 15 min notice for an hourly rate. this is very much the arrangement commercial shippers use when they pay for tug services. The difference is that the tugs would be dedicated to navy use
