Made for life under water
Enabling submerged aquaculture
Subsea Farming wants to make a change! Our vision is to culture the oceans. Subsea Farming is developing technology for submerged aquaculture to escape rough sea, thus allowing aquaculture to happen more places – even out in the open ocean.
This system will allow the aquaculture to scale up production by moving into new areas of the ocean, reduce environmental impact, improved biosecurity and fish welfare, avoid sea lice, algae blooms (if in higher layers of water column) and visual “pollution”.
What does make us special?
Subsea Farming has a unique technology that ensures stable submergence with no elements in the surface. And it is simple! Thus, investment costs are relatively low and competitive. The design is also scalable allowing farmers to start small and gradually expand. Subsea Farming develop technology for fin fish, seaweed and mussels. Submerged aquaculture escapes whatever would be harmful or negative to productivity in the higher layers of the water column such as; waves, sea lice (salmon farming), schools of jellyfish, poisoned algae or too cold or too warm water depending on season. Finally, it removes visual pollution as there are no elements in the surface. Subsea Farming has a concept – Argy – ready to be tested in salmon and other finfish aquaculture. The main design feature of the Argy is that it can be submerged below the most harmful of offshore waves, thus enabling the system to be left offshore during the worst of storms.
- Made for life under water: Can be submerge throughout the entire production cycle.
- Archimedes law: No mechanical operations; only using buoyancy and ballasting.
- Simplestructure and operating principles.
- Robust: Designed for worst of offshore conditions (15 Hs). No surface components when submerged.
- Low wear and tear: Only flexible components; natural behaviour.
- Stable submergence: The unique and simple principle of ballasting of sets of buoys ensures stable submergence of cage in all stages, maintaining structural integrity and restoring capacity.
- The Ark: A multi-purpose unit including feed silo (100 m3 – or two weeks of feeding; no feed barge in surface position), under water feeding system and air pocket. Accessible by service vessel in submerged position in sea stages of Hs < 3.
- Efficient operations: Remotely operated from land base and autonomous positioning.
- Low cost/CAPEX: Only buoys, wires and net; scalable in size; large range of water depts and locations (sheltered, exposed and offshore).
Supported by Subsea Farming’s experienced resource pool, the Argy will allow for aquaculture production that calls upon technology and knowledge from the Oil and Gas industry.
