SeaStrut Grids (SSG) - Low Trophic Aquaculture (LTA)
A versatile and cost-effective way to spread a variety of aquaculture substrates in dense arrays and in dynamic environments, while controlling buoyancy and submersion.
Variable buoyancy of slender structures for aquaculture (longlines, grids, rings)
Submersion and weight control of Seaweed, Shellfish and Finfish
Enables strategies for reducing visual impact and storm survival
Wave-activated submersion option / Auto-compensation for biomass growth option.
Quick connect and release features for attaching / releasing substrates
Patent protected: WO2021214087 and pending filings
Tube construction options: HDPE or pressure-supported hose (inflatable beam) to suit client application
Why use pressure-Adaptive Tubes?
Impact-9 uses pressure to both control buoyancy and to provide strong structural properties. Have you been camping lately? What held up your tent in the wind? Chances are it wasn’t aluminium or fibreglass tent poles. Modern tents utilise inflatable beams formed from collapsible tubes that are inflated to form a strong flexible structural member, with minimal materials. The advantages are even more pronounced for marine applications, where the same pressure can be used to affect in-situ buoyancy control using our proprietary solution.
This video shows a single SeaStrut beam under test implementation for growing kelp showing capability s such as:
Collapsible elements that offer bend / compression resistance when deployed
Can suspend nets, drop-ropes, seaweed and similar substrates
Maintains separation of substrates under dynamic loading
Buoyancy control can affect submersion of farm stock in storms
Made from flexible, durable materials with a safe over-load response
These elements form a building block solution for grids as well as future novel marine structures, like our Net9 fish pen.
