Njord Aquashipping orders advanced well-boats for improved fish welfare
Njord Aquashipping is commissioning the construction of two advanced well-boats to enhance fish welfare and environmental sustainability in aquaculture operations. Built by Aas Mek Verksted, the vessels are designed for transporting smolt and market salmon. They will feature freshwater delousing systems using self-produced freshwater and space for additional delousing equipment, setting a new standard for efficiency in the industry.

Aas Mek Verksted has partnered with CM Aqua Technologies for the filtration systems onboard. CM Aqua will provide HEX SANI series drum filters, which are designed to remove particles and sea lice from the water, ensuring a clean environment for the fish. The filters are engineered to withstand marine conditions and are easy to maintain, with optional features like a custom washing system and a “Drum Lift” mechanism for easy cleaning.

“We have maintained strong communication with Aas Mek Verksted for quite some time and have successfully developed solutions tailored to their vessel designs,”
CM Aqua representative Ole Kristian Helstad Svartaas stated.
“These well-boats need reliable and effective filtration systems to uphold water quality, and our technology is specifically engineered to meet those demands.”
The AL-2 Belt filter, used to treat backwash water, will also be installed to capture sea lice and improve sludge removal, increasing the dry matter content of the collected sludge. This system ensures clean water is returned to the sea, supporting sustainable practices in aquaculture.
CM Aqua and Aas Mek Verksted have a history of collaboration and are working on future projects to continue advancing filtration technology for the aquaculture industry. “We are dedicated to continuing our collaboration with Aas Mek Verksted, striving to develop new and effective solutions for their vessels,” CM Aqua confirmed. “This partnership allows us to refine our technology and supply the industry with the most advanced filtration systems available.”


With the new well-boats, Njord Aquashipping wants to set a higher standard for fish welfare and environmental responsibility in the sector.
