Field experiments for testing and verification of new technical solutions for exposed aquaculture sites are expected to be a major part of the work in SFI Exposed. To facilitate such experiments, the three aquaculture companies participating in Exposed have all chosen a site where the conditions are among the most difficult with respect to wave and currents. This will ensure that new technical solutions can be tested in realistic conditions. During the project period, new and even more exposed sites can be used for experiments.
Technical solutions for e-Infrastructure will be established at all these sites. In addition to instrument cabinets with standardized interfaces for digital and analogue sensors, local PC’s for data logging and battery backup will reduce the risk of loss of data. All data are transferred to database servers at SINTEF SeaLab over broadband data links, with redundancy over permanent encrypted links over a mobile network.
In addition to e-Infrastructure for field experiments, long-term data series will be established as a basis for designing new technical solutions for exposed sites:
- Oceanographic buoys: Currents, wind and wave data for ‘next generation sites’
- Kongsberg Seatex MRU (accelerometer/gyro): Movements on cage and feed barge related to logging of what kind of operations which must be postponed due to weather conditions
As part of SFI Exposed, Marine Harvest and SalMar Farming have both deployed one buoy from Fugro Oceanor (see picture below).
