The landing craft Beinn Nibheis has been constructed by Netherlands boat builder Nauplius Workboats, which is also installing a four-line Hydrolicer package on the vessel.
The Beinn Nibheis will be the last of three 27-metre x 12-metre workboats of the same design to be supplied to Mowi Scotland on 10-year contracts from DESS Aquaculture, which is a joint venture between Mowi and Deep Sea Supply (DESS), part of Norwegian shipping company Solstad.
The Beinn Dearg arrived in March and is being used as a service vessel and for transporting hydrogen peroxide for use in treating salmon for amoebic gill disease (AGD).
The second landing craft, the Beinn Bhreac, arrived in April and operates between Harris and Lewis and the north mainland.
The Beinn Nibheis is due to arrive in the week commencing August 5.
It is being fitted with the latest iteration of the Hydrolicer and new PG HydroFlow ejector pumps, which have no moving parts that can come into contact with the fish.
The vessel has increased ballast tank capacity, enabling the freeboard at the fish pen to be lower than one metre. This benefits fish welfare as it reduces the height they must be pumped up during treatment.
