CUSTOMER: Fitjar Mekaniske Verksted AS

Seihav is a Live Fish Carrier constructed and built by Fitjar Mekaniske Verksted AS in Norway.
Fish are loaded from the Norwegian waters at the farms directly onto the vessel where they are transported using semi-open and closed circulation seawater in live fish tanks. The fish are then unloaded at the processing plant where they are sorted, graded, and counted.
The process onboard the vessel relies on the use of both a seawater circulation pump system and vacuum pumps.



Due to the space available onboard Seihav, Fitjar Mekaniske needed a filter solution that would be able to fit into the main engine room, which can often exceed 40 degrees Celsius (104 degrees Fahrenheit). At temperatures this high, there is a risk of equipment overheating and/or malfunction.
With a live product to maintain and transport, Fitjar Mekaniske aimed to minimize risk as much as possible. So they sought a partner with a proven solution and tested technology that would also help them meet the DNV GL requirement for a TVHD limit of 8% and an individual harmonic limit of 5%.


Fitjar Mekaniske chose to install a trusted active filter solution that would ensure compliance with the DNV GL class requirement, make efficient use of the onboard space available, ensure redundancy, and avoid overheating.

Products used in this case:

-Two ADF P100 units (one on portside and one on starboard)

With powerful compensation capabilities, a compact size and proven success in the marine segment, ADF Power Tuning made the ideal solution for Seihav.


Seihav is now running smoothly along Norway’s coast, helping to bring rich Norwegian salmon to customers!
