Using the neither fish nor fowl justification with the Coast Guard being DND but not Navy and performing securitry tasks with ships that could be twins to those operated by the Navy (looking at AOPS), I am posting this in the Navy boards.

In Norwegian Coast Guard style the ship has a bang-stick.
....
The MSMM are expected to be 45 to 50m in length and a tonnage of < 1000MT. They will have a range of up to 3000nm and an endurance of up to 17 days. The MSMM will also be Ice-Strengthened with the class expected to be rated at minimum Ice Class-1C per DNV standards.
Ice Class 1C signifies that a vessel is designed and strengthened to navigate in light ice conditions, specifically characterized by first-year ice with a thickness of up to 0.6 meters. Per DNV standards, this classification confirms that the ship's hull, propeller, and steering gear are reinforced to withstand the thermal and mechanical stresses of ice interaction.
The MSMM will operate year-round within the Canadian waters of the Atlantic and Pacific Oceans, the Gulf of St. Lawrence, the Great Lakes, and the St. Lawrence Seaway. On the Atlantic Coast it will be limited to as far as 60° North latitude during the summer months.

I think this Nornen class might be most reflective of the type of ship being considered.

2007 design (contemporaneous to the Svalbard)
47m overall.
Light at 800 tonnes
Complement of 20.
Diesel-Electric.

"They provided significantly improved capabilities in all regards compared to the vessels they replaced. This included seaworthiness (they are larger), towing capacity, fire fighting and environmental protection (collecting oil spills). The aft deck is for the winch only (not for helicopter landing)."
....
This is the Home Guard's version of the same ship
The Coast Guard got 5 Nornens in 2007 and the Home Sea Guard got 2 Reines in 2010. Following Canadian practice, in 2013 the Reines were transferred to the real Navy for logistics support. The carry containers and small boats.
