Below is a press release from Seaspan Shipyards regarding a contract awarded for the Canadian Coast Guard’s Multi-Purpose Vessel program. We talked about these ships earlier. I am going to repeat some of that earlier post here. Much like USCG Juniper class buoy tenders or the Great Lakes Icebreaker Mackinaw, these Canadian ships are made to both tend buoys and break ice. But these ships will be a lot bigger than the Mackinaw and it appears they can also support a helicopter and probably UAS.
CHARACTERISTICS:
- Displacement: about 8,500 tons
- Length, overall: 99.9 meters (328′)
- Beam: 20.3 meters (66.7′)
- Draft: 6.2 meters (20’4″)
- Propulsion: diesel-electric; two azimuthing propulsion units
- Range 12,000 nautical miles
The relatively shallow draft was a design requirement.

ICE CLASS:
These ships will be Canadian Ice Class 4, meaning they will have the capability to maintain a speed of 3 knots through ice 4 feet thick. The Canadian Coast Guard will consider these heavy icebreakers. We don’t have any figures on horsepower, but they probably will have less than 20,000 HP which, in the USCG system, would classify them as light icebreakers.
Compared to the US Coast Guard’s “heavy” Great Lakes icebreaker, Mackinaw (3,500 tons and 73m), these will be more powerful and more than twice as large. These might be a good design for the planned second USCG Great Lakes icebreaker.
IMPLICATIONS FOR THE USCG:
Aside from possible use of the design for Great Lakes icebreaker, these might be pretty close to what the USCG needs for their planned medium icebreakers. Certainly, consultation with Canadian counterparts will sharpen the focus of the US design effort. We might also have reasons to limit beam and/or draft.
I might add that, ships like these could make good companions (tenders/mother ships) for support of distant FRC operations, carrying fuel, supplies, and air assets.
Seaspan Shipyards Progresses to Next Phase of Designing and Building Multi-Purpose Vessels for the Canadian Coast Guard
March 26, 2024 – North Vancouver, BC – Seaspan Shipyards (Seaspan) has been awarded the Construction Engineering (CE) and Long Lead Items (LLI) contracts for the pre-construction work of the Canadian Coast Guard’s (CCG) first six Multi-Purpose Vessels (MPV).
Following the successful completion of the vessel’s Basic Design review in late 2023, Seaspan was awarded the CE and LLI contracts to complete the design and engineering work and to procure long lead-time material and equipment to ensure readiness to proceed with the construction of the first six ships of the up to 16 vessel fleet.
“This milestone demonstrates the tremendous capabilities in marine design and engineering that have been developed through the National Shipbuilding Strategy. Our team, along with our partners from coast to coast, are excited to move to the next phase of this program, and ultimately provide the Canadian Coast Guard with the vessels they need to manage and safeguard Canada’s coastlines. A long run of ships like the MPV program enables Seaspan to continue to drive improvement and generate greater efficiencies, while ensuring we have stability for the next generation of shipbuilders, marine engineers and designers and supply chain in Canada,” said John McCarthy, Chief Executive Officer, Seaspan Shipyards.
“The designers and the ship builders of Seaspan Vancouver Shipyard – are playing key roles in taking the Canadian Coast Guard’s new multi-purpose vessels (MPVs) out of the drawing room and into the open ocean. The contracts announced today are an important milestone to getting these ships completed and represent an important investment in North Vancouver. This will secure good jobs while advancing the delivery of the MPVs to significantly expand the operational capacity of our Coast Guard for years to come.” – The Honourable Jonathan Wilkinson, Minister of Energy & Natural Resources and MP for North Vancouver.
The MPVs will be Polar Class 4 vessels, allowing them to carry out multiple missions including icebreaking in moderate ice conditions and assisting in shipping and flood control, search and rescue, environmental response, as well as maintaining Canada’s marine navigation system composed of approximately 17,000 aids to navigation. The new fleet of MPVs will replace the existing fleet of High Endurance Multi-Tasked Vessels and Medium Endurance Multi-Tasked Vessels.
“The Canadian Coast Guard saves lives at sea, maintains waterways open and safe for the movement of goods and services, protects the marine environment and supports Canadian sovereignty and security. The Multi-Purpose Vessels will be key assets for the Canadian Coast Guard’s future fleet, giving our personnel the modern, reliable tools they need to continue their vital work from coast to coast to coast,” said Mike Kelloway, Parliamentary Secretary to the Minister of Fisheries, Oceans and the Canadian Coast Guard.
Seaspan has already gained significant experience designing and building Polar Class vessels including three Offshore Fisheries Science Vessels which are now in service with the Canadian Coast Guard; an Offshore Oceanographic Science Vessel that is currently under construction; and a heavy Polar Icebreaker, the first of its kind to be designed and constructed in Canada in 60 years. Seaspan is preparing to cut steel on the Polar Icebreaker in late 2024 with the recent completion of a prototype block, ensuring that proper processes, procedures, and equipment are in place to build a vessel of this complexity.
QUICK FACTS ABOUT THE MULTI-PURPOSE VESSELS
- With a displacement of 8,500 tonnes, the Multi-Purpose Vessels will be 99.9 metres long and 20.3 metres wide, and able to accommodate up to 50 personnel.
- The area of operation for the MPV will include:
- Year-round operations in Canada’s eastern and western seaboards, within Canada’s Exclusive Economic Zone (EEZ)
- Year-round operations in the Gulf of St. Lawrence, the St. Lawrence River, and the Great Lakes
- Seasonal (summer) operations in the western and lower Arctic
- Under the NSS, Seaspan has become a major economic and job creation engine. According to an economic analysis conducted by Deloitte, Seaspan has contributed $5.7 billion to Canada’s GDP since 2012, while also creating or sustaining more than 7,000 jobs annually.
