At Leask Marine, we provide complete end-to-end solutions for the installation and protection of subsea cables in the critical landfall and nearshore environment.
These stages are among the most technically demanding in any offshore wind, interconnector, tidal, or telecom project, as they connect offshore infrastructure to the onshore grid or communications network and safeguard the cable where it is most exposed.
With decades of experience and a true one-stop-shop of in-house resources, Leask Marine delivers safe, efficient, and environmentally sensitive operations that ensure long-term reliability of subsea cable systems.
Nearshore Cable Protection Operations
At Leask Marine we understand that the nearshore zone, the shallow waters between the surf area and deeper seabed, is where subsea cables face the greatest risks from wave action, currents, vessel anchors, fishing activity, and seabed movement.
Leask Marine provides a full range of engineered solutions to stabilise and protect cables in this challenging environment.
The Leask Marine Protection Techniques include:
- Trenching & Burial – placing the cable or ducts beneath the seabed.
- Rock Bagging – targeted stabilisation using rock filter bags.
- Concrete Mattressing Concrete Mattressing – articulated protection in high-energy areas.
- Cable Pinning & Clamping – securing on rocky seabeds with rock pins & resin, or placing half clamps along the duct or pipeline.
These challenges require seamless coordination between our marine crews, onshore civil teams, dive teams, and HDD & cable contractors. By integrating all these capabilities under one roof, Leask Marine delivers safe, efficient, and reliable cable pull-in operations that meet the highest technical and environmental standards
Our Nearshore Cable Protection Processes include:
1 – Seabed & Route Assessment
Leask Marine can surveys assess seabed conditions and identify the most suitable protection method.
2 – Preparation & Access
Leask Marine vessels, dive teams, and support crews mobilise to the shallow water site.
3 – Protection Method Deployment
The appropriate stabilisation solution is installed based on site conditions.
4 – Cable Stabilisation & Securing
Protection measures are carefully placed and monitored to ensure cable integrity.
5 – Verification & Handover
Post-installation inspection confirms stability before final handover.
Specialist Pipeline and Cable Anchorage Solutions
Leask Marine is highly experienced in the installation of half clamps, rock pins, and resin anchors to secure pipelines, cables, and ducts in both nearshore and offshore environments.
Our team provides reliable, long-term protection against movement, scour, and seabed instability, combining precise engineering, specialised equipment, and meticulous installation techniques. From mechanically securing pipes with half clamps to anchoring with rock pins and marine-grade resin, Leask Marine ensures durable, safe, and resilient subsea infrastructure in challenging marine conditions.
