Denmark-based Tuco Marine has launched a boat which carries out high pressure net cleaning of remotely operated underwater vehicles (ROVs), to be used for fish farm operations in Norway.

The 15m long ProZero HPC, part of Tuco Marine’s ProZero series of workboats, is built from composite materials which reduces its structural weight, while a reinforced hull to help it stabilise in rough seas.

Jonas Pedersen, managing director of Tuco Marine, said: “We are extremely happy to have launched this fantastic vessel and once again prove that our ProZero workboat concept is a great tool for owners seeking top performance and reliability while also taking great care of the crews on board. With the vessel, we once again surpass the market expectations for such boats.”

The vessel features twin inboard diesel engines connected to a Volvo Penta IPS propulsion system with forward-facing, counter-rotating propellers.

Its low weight, diesel engines and efficient propulsion jointly enable the vessel to operate at more than 33 knots, with excellent control and handling, fuel efficiency and minimal environmental impact, stated Tuco Marine.

The interior layout is set up to optimise the use of monitoring systems and navigation technology.

The boat has undergone rigorous sea trials including vessel speed, manoeuvrability, equipment functionality and safety feature testing.

To preserve a healthy fish population and a steady production rate, aquaculture facilities must ensure good net hygiene by removing marine fouling. This is often done through mechanical net cleaning. Cleaning takes place by sending a tethered ROV tautly along the nets while pumping filtered, high-pressure sea water through the net masks.
