Aquaculture Service boats

There are more Aquaculture Service boats in operation and they are getting more sophisticated as the industry develops around the world.
Here is a new one that just crossed the Atlantic to work in B.C, Canada:

After sailing on its own keel across the Atlantic to the Caribbean, the Coastal Server arrived in Victoria, British Columbia, on the west coast of Canada just before Christmas. In the next few years, the boat will carry out service operations for the fish farming company Grieg Seafood.

• Crossing the Atlantic for your own machine is not an everyday occurrence for work boats in the aquaculture industry, but we were never in doubt that Coastal Server could carry out such a voyage. Nabwork 2411 are strong boats, says Terje Andreassen, CEO of Moen Marin AS in a press release.

I believe there was a class of 4 or 5 of these but this was the only one that came across the pond to BC

The Aqua Tromøy is a mid-size Live Fish Carrier that can also be used to remove lice and other parasites from the fish, using fresh water.
Having Diesel/Electric propulsion allow the 4 generators to be used to power Reversed Osmosis (RO) to produce up to 6000 Cbm./day of fresh water when not steaming:

The Coastal Server use a Skarmik 1.5 mechanical de-licing system and cover a wide range of other tasks around fish farms.

PS> The design has already proven it’s seaworthiness:

Coastal Server is a sister ship to AQS Tor which received wide media coverage after it launched itself from the deck of the wrecked cargo ship Eemslift Hendrika in the spring of 2021. Both are of the type Nabwork 2411 and have a length of 23.98 meters and a width of 11, 2 meters.

UPDATE:
Mowi MAY reduce their fleet of chartered vessels operating in B.C. soon:
