Helical Screw Anchor Mooring Systems for Aquaculture & Offshore Farming
Eliminate heavy concrete block logistics for your mooring field. Our helical torque anchors install from a small work vessel — delivering 4–5× holding strength, immediate load capacity, and 2:1 warp space savings for finfish, shellfish, and kelp operations.
The Problems That Cost You Time, Money & Permits
Heavy Concrete Block Logistics
The Challenge
A single concrete deadweight equivalent to a screw anchor requires a 12–15 m³ block (25–30 tonnes) transported and deployed by expensive crane barge.
Our Solution
Our helical torque anchors install from a small surface vessel — no crane barge, no concrete logistics.
Concrete Curing Delays
The Challenge
Concrete deadweights require curing time before safe loading, creating critical delays in seasonal deployment windows.
Our Solution
Screw anchors provide full certified holding capacity the moment target torque is reached. Deploy and load the same day.
Farm Layout Density Constraints
The Challenge
Conventional mooring systems require excessive scope lengths that limit how many long-lines or cages can fit within your lease area.
Our Solution
Our conservation mooring system delivers 2:1 warp space savings, allowing significantly higher stocking density within the same licensed area.
How Screw Anchors Transform Aquaculture Mooring
Deep-water aquaculture environments expose mooring systems to extreme wave forces, sustained tidal currents, and cyclic dynamic loading. Helical screw anchors are the only mooring solution specifically engineered to excel under all of these conditions simultaneously.
Exposed offshore sites demand anchors that can withstand wave, current, and storm surge forces without shifting or dragging. The torque-to-capacity installation method verifies holding capacity in real time — every anchor is certified before you leave the site.
