This is risky, expensive, and there are major limitations in operation due to lighting conditions and environmental aspects such as current, wind and wave height. This often results in an interruption in the harvesting for environmental reasons. This most often happens in the cold, dark season when the market (internationally) demands the most of this type of seafood. The result is that the company can not maintain the regularity required by the recipient, and that the price the suppliers can achieve is also reduced. Regularity is stated as an important criterion for advantageous contracts for foreign buyers.
If it proves to be efficient to harvest with a remotely operated mini submarine, so-called ROV (remotely operated vehicle), this will mean that it can be harvested even in the dark season as well as under environmental conditions where divers can not operate. During the first test, 14-18 September at Scan Aqua AS, Seabed Harvester (SH) managed to harvest at least in waves as large as the divers and that there were no restrictions regarding. light. There will of course be limitations for SH as well, but this applies to surgery near the surface. If the sea is rough, SH will still be able to harvest in deeper water. The purpose of the test will be to uncover which restrictions will apply, and thus be able to estimate how much one can expect to harvest over time.
To find out / determine whether one can achieve continuous and cost-effective harvesting of sea urchins, also during the winter season, by using advanced underwater technology such as the remote-controlled mini submarine (ROV) -based Seabed Harvester, developed by 7S-Technology AS and Sperre AS (ROV technology).
