Shore Approach

Connecting offshore and onshore pipelines through the coastline.

Overview

Landfalls built for the conditions

Shore approaches are among the most demanding parts of a pipeline. We choose the method to suit the seabed, the shoreline and the environmental limits.

  • Open-cut trenching through beach and surf zone
  • Sheet-pile cofferdams and pre-trenching
  • Horizontal directional drilling (HDD) landfalls with trusted specialist partners
  • Pipe pull-in from lay vessel or onshore winch
  • Backfill, rock armor and shoreline reinstatement
