Intership gets new wellboat for work in Scotland and Canada

Vessel adds freshwater treatment capacity for lice and gill disease

Published Last updated

A wellboat that will operate for a salmon farmer in Scotland before moving to Canada has been delivered to Norwegian company Intership by Zamakona Yards Bilbao.

The Inter Atlantic, which has a load capacity of 2,200 m³, is designed with focus on promoting good fish welfare, fish handling and biosecurity.

The vessel is 72.2 metres in length, 17 m wide, and 6 m deep.

It is equipped with a high-capacity freshwater production system, capable of producing 5,000 m³ of fresh water per day and has a fish handling system from MMC First Process.

Intership said that since 2016 it has taken the lead in developing freshwater treatment for lice and amoebic gill disease (AGD) using a reverse osmosis (RO) system, gaining extensive experience.

This has been used to actively develop and improve the technology, resulting in an RO system that provides a low-cost, highly efficient, and environmentally friendly method for dealing with the lice and AGD challenges faced by salmon farmers.

'The gentlest method'

“Freshwater treatment is possibly the gentlest method used to treat of salmon, and it is therefore with great pleasure that we take delivery of another newbuild, with our industry leading freshwater production and treatment setup,” said chief executive Ole Peter Brandal in a press release.

Intership already operates the 2,210 m³-capacity wellboat Inter Caledonia in Scotland, and has a slightly larger vessel, the 2,500 m³ Inter Scotia, due for delivery from the Zamakona yard next year.

The 76.6-metre newbuild was designed by Salt Ship Design and will be equipped with a large battery pack, solutions for energy recovery and be prepared for the installation of a large capacity RO plant.

Intership is due to take delivery of two further vessels in 2024 from the Sefine shipyard in Turkey. Both will be battery hybrids, and will be equipped with mechanical delousing equipment and RO.

One of the boats will be 92.66 metres long, with a well capacity of 6,500 m³, and the other 80.8 m, with a capacity of 4,000 m³. The vessels will increase Intership’s fleet to 11 wellboats.

The Inter Scotia is due for delivery next year.
