located in Hirtshals, Denmark. New net models are tested here to investigate how they react to currents and how the weight loading can be optimised on different net models and weight loading systems. ‘We receive a lot of interest from Norwegian fish farmers who want to visit the flume tank, where they get important input on how the ocean currents affect the nets. This is some- thing we also offer to our international custom- ers,’ says Hildre.
MøreNot Group has its own consultancy department. They use an advanced analysis and simulation software called Aqua Sim to construct nets that tolerate the forces they are exposed to in extreme conditions. Aqua Sim demonstrates how the different components affect each other and a unique perspective on how the totality of a fish farm functions is gained. ‘Aqua Sim can simulate various approaches to problems the customers might experience. You can actually plan how a fish farm will work in real life with simulated waves and currents. The computer calculates the tension on nets, cages and moorings. Experiences from the test tank and the analysis are actively used when constructing and dimensioning fish farms. It is also valuable when customers seek guidance or product information,’ observes Hildre.
Beneficial net log
MøreNot has created a separate net log that serves as an important tool for the company and the fish farmers. All nets manufactured by the company, and their partners abroad, are registered in the net log along with user manu- als, drawings and certificates. After servicing a net, a service report is added documenting fac- tors such as repairs done, measurements and breaking strengths. Registration takes place during the entire life cycle of the net. Through this database, fish farmers always have access to updated information on use, damages and service on their nets. They can also add photos

taken during inspections by divers to docu- ment possible problems. ‘The nets are frequently moved around, so this is an essential tool for the fish farmers – as they get access to correct and updated information on their nets whenever required. In a long-term perspective, this will give us relevant statistics on the individual net and provide a foundation for a more in-depth analysis of repetitive damages, which will be a catalyst for improving our products and give good advice to our customers. All aspects of the net log are important in the prevention of escapes,’ says Hildre.
Knowledgeable customers NSS believe that sufficient product information reduces the risk of incorrect use. ‘We feel that it is important to always work closely with our customers. During severe weather conditions, mistakes are easily made and may cause dam- age to the nets. We also advise our customers with regards to the weight loading of the nets,’ says NSS General Manager, David Goodlad. The fish farming industry has experienced radical changes in recent years, and fish farm- ers today have totally different requirements compared to just 10 years ago.
‘Fish farmers are educated within the aqua- culture field and require user manuals and instructions regarding the products’ endur- ance. This intensifies the requirements we meet as manufacturers and we are naturally only happy to provide the necessary documen- tations,’ says Hildre. In Norway, MøreNot is working closely with their customers to update their user manuals. ‘Due to different methods found amongst the fish farmers, this is quite challenging. But, together with fish farmers and the Norwegian Directorate of Fisheries Inspectors, this work is making good progress and we believe the user manuals will become another significant tool in the struggle against escapes,’ con- cludes Hildre.
