Hybrid vessel reflects changing demands of Scotland’s fish farms

The vessel, Naomi Jennifer, was built by Macduff Shipyards to a design by Macduff Ship Design, and represents Inverlussa’s latest investment in fleet renewal as farming operations continue to scale up.

According to the company, the vessel was developed to meet stricter environmental standards while also handling increased loads on modern fish farm sites. Naomi Jennifer is fitted with IMO Tier 3-compliant engines supported by a hybrid system capable of storing electrical energy for use during operations, reducing fuel use, emissions and onboard noise.

Ben Wilson, managing director of Inverlussa Marine Services, said the vessel reflects gradual changes in operational requirements rather than a single step change.

“She represents a steady progression in our investment in modern and environmentally responsible vessels,” said Wilson. “The vessel will strengthen our ability to support customers across a wide range of operations while continuing to provide a safe and dependable working environment for our crews.”

The vessel has been equipped with upgraded cranes, additional thrusters and new deck machinery to handle heavier anchors, towing loads and farm equipment. The wheelhouse layout provides full visibility of deck operations, including full-height aft windows and a secondary control position facing the working deck.

Crew accommodation was also a key focus during the build. The vessel includes five en-suite cabins split across the main and lower decks, along with a large communal galley and lounge space. Noise reduction measures were incorporated throughout the accommodation areas to improve living conditions during extended operations.

John Watt, managing director of Macduff Shipyards, said the project continued a long-standing working relationship between the two companies.

“Their operational expertise has helped shape a vessel that reflects how fish farm support work is changing,” he said. 

The delivery marks the tenth collaboration between Inverlussa and Macduff Ship Design. Naomi Jennifer brings Inverlussa’s fleet to 23 vessels and will operate with two rotating crews of three, contributing to a workforce of around 145 seafarers based across Scotland.

“It reflects the increasing scale of aquaculture operations while also addressing environmental performance and crew welfare,” said Macduff Ship Design managing director Ian Ellis.
