Grieg Seafood is one of the world’s biggest salmon producers and a world leading fish farming companies, with an annual production target of 100,000 tonnes gutted weight (in 2020). They were listed on the stock market in 2007 and today the company (all departments included) employ almost 1,000 people.
Behind their success is both craftsmanship, dedication, determination… and technology! Running a large modern fish farm is almost impossible without modern technology. This is especially true for land-based RAS facilities. Changes in water quality, a pump that does not work properly, a malfunction in a filter etc. can quickly create a situation that puts the entire stock at risk – in the worst cases causing mass die off. Often these dramatic events could have been prevented with a simple monitoring-alarm system.
Grieg Seafood
At Grieg seafood’s smolt facility on Trosnavåg, Norway, nothing is left to chance. Everything is carefully monitored and the majority of the equipment on the facility is under automatic control. In case of pump failure, water level deviations, oxygen loss etc., they will get a notice within seconds. They use OxyGuard’s Commander Pacific, and they are very happy with the system.
The manager, Atle Jøsang explains, “We chose the Commander Pacific system for several reasons. First off, we have a good connection to the technicians at OxyGuard, and we knew that they would provide the service we needed. This is an important thing, especially during the start-up of a facility where changes happen all the time. These systems are, to a large extent, tailored to the specific facility and the distance between success and failure lies in the margins.”
Stand Alone
OxyGuard’s Commander Pacific is a so-called ‘stand-alone system’. Everything can be controlled and monitored from a central monitor with touch screen. The graphical interface allows the user to get a good overview of the entire farm including conditions in the individual tanks. Everything can be monitored directly from this main unit, or from a PC, smartphone, or tablet. From the touch screen, tank specific information on oxygen saturation, pH, water level etc. can be accessed simply by clicking the tank icon on the screen. A graduated alarm system indicated with colour codes gives a quick overview of the conditions on the farm and makes it easy to locate a problem before it gets serious. Alarm specification can be given on-the-go via text messages or email. The user can determine the set point for different alarms depending on the farm-specific needs.
