PG-HydroFlow to salmon delousing barge

17 September 2018 – PG Flow Solutions has been contracted to supply its PG-HydroFlow fish pumping solution to a salmon delousing barge that Dutch shipbuilder Neptune Marine will build for Cermaq Canada.

Liquid handling and pump specialist PG Flow Solutions will deliver the pump system as a subcontractor to Norwegian companies Hydrolicer Production and Cflow Fish Handling, who will deliver a complete fish delousing system to the barge. PG’s contract value is undisclosed.

PG-HydroFlow is a live fish transfer, non-mechanical pump solution that enables delousing vessels, wellboats and service boats to convey live fish at a rate of 30 – 40 tonnes per hour per pump, without harm or trauma. PG-HydroFlow will be combined will the Hydrolicer system to ensure safe and effective delousing of salmon.

PG-HydroFlow will be used in combination with Hydrolicer’s non-medicamental system that delouses fish in a closed water column. The system creates water turbulence that causes the lice to lose its vacuum-based grip of the fish surface. Hence, the lice is lifted – not flushed – off the fish, which is a more gentle way of delousing.

“Our non-mechanical pump solution ensures excellent fish welfare with close to zero harm or trauma to the fish. Our pump system in combination with Hydrolicer’s delousing unit is extremely effective. We are very pleased to be able to support Hydrolicer and Cflow on this project,” says Øyvind Berg, vice president sales & marketing at PG Flow Solutions.

Neptune Marine will build the 31-metre non-self propelled barge – called a Euro Special Purpose Pontoon – at its yard in Aalst, the Netherlands. Delivery is scheduled for Q1 2019. The fleet will be equipped with four lines (with space for an extra two), which has the capacity to unload 50 tons of fish per hour.
