HS2 Goes to sea

The first sea-going HS2 was successfully installed on the MV Tauranga on the 5th November 2008. Three months ago Marine Harvest Norway commissioned Ace Aquatec Ltd to design, build and deliver an HS2 for its new sea-going factory ship. The machine was required to do the following: humanely kill salmon that were too difficult for percussive stunners, fit inside a deck space of 3 metres by 1 metre, cope with a list of +/-5 degrees, have a throughput of 2 Tonnes per hour and be built and delivered within 4 months.

Nicknamed the 'Runt Stunner' the machine has met all the criteria but also goes beyond it in several ways: it automatically levels itself depending on the list of the ship, it can be fully operated from a remote location and can harvest fish of up to 5kg at a rate of 6 Tonnes per hour. It is also the first Ace Aquatec stunner that runs on pure sea-water which greatly simplifies the logistics of operating at sea.

Marine Harvest's Operations Manager, Steve Harris, commented. "We are impressed by the simplicity of the design and the hidden sophistication of the electronics. We have high hopes for the Runt Stunner."

Sea Trials are scheduled later this month.

Celtic Salmon take delivery of HS2 Salmon Stunners

Ace Aquatec Ltd. have recently completed a double installation of the 12" HS2 humane electrical stunner at Killary Salmon in Galway, Ireland.

Jim Murrin – Managing Director – commented; "We were impressed by the stunning efficiency of the HS2. The fish exited the machine as if they were dead which makes the job of gilling that much easier. The HS2 is very easy to use and our operators are delighted with the system. Our processors like the quality of the salmon which they graded as over 97% superior with a blood-spotting rate of 2%."

Readers are reminded that the 12" HS2 machine is the world's fastest humane slaughterer with a capacity of 12 Tonnes per hour.
