Ronja Ocean

Mekon, Lilleborg and System Cleaners have jointly developed a new customised automatic cleaning system for onboard delousing tanks applied in the fish processing industry

The automatic system is installed to safeguard the fish against infections, simplify the cleaning and reduce the cleaning costs, according to a press release by Mekon.


Mekon, System Cleaners and Lilleborg (System Cleaners’ distributor in Norway) jointly developed the solution installed on board the wellboat Ronja Ocean, owned by Oppdretternes Miljøservice AS in Norway. Integration of the solution on the boat has been a joint effort as well.

With a single press of a button, the rotating nozzles rinse, apply foam and disinfect the mechanical delousing tank aboard Ronja Ocean.


Reduced cleaning time - Consistent cleaning - Reduced overall operational costs

"Now we don’t have to enter the delousing tank dressed in boiler suit and water proofs, and the cleaning time has been significantly reduced. The working day is simpler, we have time for other tasks and the delousing unit is ready for the next batch of fish faster than before,” the seamen on Ronja Ocean Tellef T. Elverum and André Balstad state."
