Deploying a TEAM of highly trained professionals and specialty installation equipment, AnchorPipe works closely with operators and world class EPC customers and dive teams to deliver engineered buoyancy control and stabilization and mooring solutions for nearshore and deep-water applications. Evaluating soils data, buoyancy, current, wave and other hydrodynamic forces, TorcSill Engineering designs helical anchoring solutions for projects involving:

  • Floating Docks
  • Offshore Tie-Ins
  • Onshore Approaches
  • Outlet/Intake Piping
  • Pipeline Crossings
  • Pipeline Span Remediation
  • Solar Arrays
  • Subsea Structures
  • Subsea Work Habitats
  • Transmission Pipelines


Relying on decades of experience, the Anchorpipe Project Execution TEAM safely and efficiently installs the specified anchor foundations from barges using a vessel-mounted crane rigged to its unique twin-drive installation system.  The twin-drive system consists of two torque motors mounted in a steel frame that counterbalance the torque applied to both anchors, allowing for a complete anchor set (two anchors and the specified termination attachment) to be installed in a single approach.

Also ideal for remediation projects where scour and underwater currents have left pipelines exposed and unsupported, this type of construction operation greatly reduces safety risk, schedule and mobilization costs.  Additionally, the no-vibration and low noise installation creates little to no impact to the marine life environment when compared to less reliable methods such as concrete set-on weights, concrete-coated pipe and sandbags.
