Impact-9 develops flexible marine structures and engineering solutions that enable aquaculture systems to scale efficiently across coastal, nearshore and exposed environments. Our technologies support higher production intensity, lower visual impact and modular deployment for shellfish and seaweed cultivation, while also enabling submersible fish farming systems for improved environmental performance and future offshore expansion. From coastal production today to more exposed environments tomorrow, we apply offshore engineering principles to create scalable aquaculture systems with consistent operating methods.
Seaweed & Shellfish
Flexible cultivation support systems for suspended offshore production.
SeaStrut pressure-supported structural grids provide deployable, buoyancy-controlled support architectures designed for shellfish, seaweed and other suspended cultivation applications. By combining compliant structures with active buoyancy management, systems can be adapted for increasingly energetic operating environments.
FinFish Farming
Engineering solutions for safer and more resilient fish production systems.
Impact-9 applies flexible structural principles and buoyancy control technologies to support submerged and storm-resilient farming operations. Applications include buoyancy-controlled submersion systems, inflatable sinker ring concepts and novel structural approaches for future containment systems operating in energetic conditions.
Engineering Services
Marine engineering expertise for site-specific aquaculture challenges.
Impact-9 combines offshore engineering methods with practical aquaculture delivery to support farmers, technology developers and project partners. We provide engineering support across farm design, hardware integration, installation and operational optimisation, tailored to specific sites, species and operating conditions.
These solutions are all enabled by our core technology: SeaStrut modular, pressure-adaptive cultivation tubes.
Clean. Secure. Productive. Sustainable.
SeaStrut
Impact-9 develops aquaculture systems built around pressure-adaptive cultivation tubes: structural elements that use pressure both to provide buoyancy control and structural strength. Unlike conventional rigid systems that rely on increasing mass and stiffness, pressure-adaptive tubes dynamically adjust their operating state according to environmental conditions. Pressure can be used to:
• Provide stable, distributed and proportional buoyancy control
• Increase structural stiffness during storm conditions
• Enable autonomous submergence when energetic wave conditions arise
• Reduce material requirements through lightweight compliant structures
• Create passively regulated systems that adapt to changing loads and biomass accumulation
The same underlying technology enables suspended cultivation grids, buoyancy-controlled fish farming systems and future offshore production concepts. SeaStrut pressure-adaptive tubes are the building blocks underpinning Impact-9 integrated farm solutions.
Low Trophic Aquaculture - Reliable, Scalable Productivity
Seaweed & Shellfish: Submersible Grids with Adaptive Control
We provide farm solutions for seaweed and shellfish producers seeking reliable, scalable and highly productive farms. SeaStrut Grids use pressure-supported tubes to spread substrates in aggressive environments. These minimise material inputs, facilitate rapid substrate connections and offer innovative harvesting methods. Autonomous buoyancy control delivers submersion for storm protection as well as depth control for growth optimisation. Grid solutions are optimised for seaweed producers seeking high productivity per area or access to more scalable offshore, energetic marine sites. Mussel production can benefit from higher flow sites, novel substrate connection solutions, attenuation of wave dynamics and buoyancy control to compensate for biomass growth.
