Stealth health
Revolutionary technology brings efficient and gentle net washing
OCEIN (Ocean Innovation), the Norwegian innovation and development company, has further increased its presence within the aquaculture industry. Ocein has utilised its experience in the blue water industries of oil and gas, diving, construction and aquaculture, to bring the Stealth Cleaner Mark2-ROV (remotely operated vehicle) to market.
After two years in development and a test period which involved washing 3,500 nets, Ocein is confident it has a completely new and innovative solution for the gentle and efficient washing of nets.
Ocein COO Roy Magne Ohren told Fish Farmer: ‘Stealth Cleaner is probably the most efficient and gentle multi-tool groove cleaner on the market, combining a large amount of water with low pressure to reduce wear and tear on use.’
The unique triangular design of the Stealth Cleaner gives 360-degree manoeuvrability which allows the ROV to get to even the most difficult places within the nets, ensuring unparalleled cleaning with the minimum of disruption.
A revolutionary pressure flow technology delivers exceptionally effective cleaning without any wearing on the groove.
This multi-tool is of an electric powered, modular design, which means the Stealth Cleaner can ‘swim’ harmoniously with the fish in the cages without any risk of spillage and without high frequency sounds or vibrations, therefore keeping stress to a minimum.
‘This is very important for fish health,’ said Ohren. ‘Fish react negatively to high frequencies and vibration, and as the Stealth Cleaner is electric, there is no danger of damaging the fish or the environment.’
Fitted with seven thrusters and seven washing discs, four cameras and four LED lights, a high pressure umbilical hose and a patented front cleaning tool, the Stealth Cleaner is highly efficient and effective as both a washer and inspection robot.
The success of this ROV can be measured with sales already reaching 30 units since its launch. The increase in demand is attracting overseas interest, which has seen the company expand and employ more staff and seek distribution opportunities in other territories.
The cleaner washes at a speed of 3-4 knots, combines large amounts of water with low pres
sure, and is easy to control, even in the most difficult areas.
The ROV moves smoothly and easily through the water, meaning it can be quickly moved on to the next cage.
It is both fast and efficient, and with the benefit of four cameras, washing is easily monitored, particularly ensuring effective removal of any fouling in or on the groove.
And after the inspection and cleaning process, the Stealth Cleaner facilitates documentation and reporting.
‘Stealth Cleaner is probably the only multi-tool in the industry,’ said Ohren. ‘Further development will be to build on this concept- that one product can be used for several operations. It supports our philosophy on sustainability.’
Ingrid Sara Grimstad Amundsgård, CCO at Ocein, said: ‘Our mission at Ocein is to make service operations for aquaculture safer and more efficient- for people, for fish, and for the environment. At Ocein, our vision is to see and go ‘beyond innovations’.’
