Every installation follows a predictable, engineer-led workflow — from soil analysis and anchor configuration through hydraulic deployment, real-time torque verification, and immediate commissioning. No curing. No guesswork.
A field-proven workflow that delivers certified holding capacity before our crew leaves your site.
Step 1
Before any anchor is specified, we conduct a thorough site assessment evaluating water depth, tidal range, wave/current exposure, and soil conditions. Geotechnical data (CPT, SPT, or soil sampling) informs anchor configuration, helix diameter selection, and required embedment depth.
Soil classification determines Kt factor for torque-to-capacity correlation.
Step 2
Based on required holding capacity and soil profile, we select shaft diameter, helix plate diameter (multiple diameters available), and number of helices. In soft mud or silt, shaft extensions allow bypassing of weak surface layers to reach competent bearing strata.
Multiple helices distribute load over larger soil volume in weak cohesive soils.
Step 3
Installation is performed using compact hydraulic torque motors — surface-driven from a small work vessel or barge. No crane barge required. For subsea installations, submersible hydraulic tools operated by divers are deployed. For shoreline work, amphibious excavators provide access where vessels cannot reach.
100% driverless, surface-managed. No divers required for standard installations.
Step 4
As the anchor advances, a digital torque indicator continuously monitors and records installation torque. Final installation torque (T) is averaged over the last three helix diameters of embedment. Holding capacity is calculated on-site: Qult = Kt × T. A certified capacity record is produced before the crew leaves.
Eliminates the need for post-installation load testing.
Step 5
At target torque, the anchor is immediately ready for full structural loading. Mooring hardware, dock structures, or foundation connections are made while the installation equipment is still on site. No waiting. No curing. Your project is operational the same day.

Step 4 relies on the torque-to-capacity correlation — the mathematical method that converts installation torque into verified holding capacity on-site.
