Site intake
Coordinates, load profile, soil class, permits, and timeline.

The science under the seabed
A foundation method engineered for marine reality.
Helical piles are not new — but applying them at marine scale takes purpose-built rigs, soil-class-specific helix geometry, and torque-verified QA. Here is the technology behind every install we ship.
Certified & benchmarked against industry standards
- Hot-Dip Galvanized per ASTM A123/A153
- U.S. Army Corps of Engineers Compliant
- Zero Spoil Installation Certified
- ISO 9001 Quality Management
- IMCA Marine Contractor
- DNV-GL Type Approved Helices
How it works
A predictable process from intake to capacity certificate.
We treat every project as an engineering exercise — not a guessing game. Here is the path from your first call to a signed-off install.

Step 2
Engineering design
Helix geometry, pile spacing, redundancy, and capacity certificate plan.

Step 3
Mobilisation
Crew, rigs, ROV (if needed), and helices delivered to your nearest port.

Step 4
Installation
Torque-logged install at 12–18 piles per crew per day, weather permitting.

Step 5
Capacity sign-off
Per-pile QA records and an engineer-stamped capacity certificate.

Torque correlation
Reading a soil class like sonar.
Installation torque, recorded continuously by the rig, correlates predictably to ultimate capacity once you know the helix geometry and soil class. We deliver torque-verified records with every install.
- Continuous torque logging via hydraulic transducer.
- Soil-class-specific Kt correlation factors.
- Capacity certificate issued per pile.
