Trenching, burial, and protection

We protect cables through trenching and burial, reducing your risk of damage, interruptions, and costly repairs.

What questions we answer

Which method provides the best long-term protection for my cable? How do I reduce future maintenance and repair costs?

A cable only becomes a robust investment when it is properly secured against external influences. We carry out trenching, jetting, and securing based on actual conditions along the route, ensuring that each solution is tailored to seabed conditions, depth, currents, and activity in the area.

Our work includes cable burial in the seabed, jetting in sediments where excavation is required, covering and stabilizing the cable, and the use of protective measures such as mats or rock placement where necessary. We also adapt solutions at crossings and in exposed areas to ensure long-term stability.

We perform detailed risk assessments along the entire route, including anchor dragging, fishing activity, currents that may cause erosion or exposure, as well as seabed materials and stability. Based on these evaluations, we select the appropriate methods and level of protection to ensure the cable remains secure and operational throughout its lifespan.

Trenching, burial, and securing are particularly relevant in post-installation phases, where the goal is to protect the cable and ensure stable operation over time. This is especially important in high-activity areas such as shipping lanes, anchoring zones, and fishing grounds, where cables are exposed to external forces and mechanical wear.

These services are also essential where seabed conditions pose a risk of movement, erosion, or exposure, as well as in the rehabilitation of existing cables. By implementing targeted protective measures, we extend cable lifespan, improve reliability, and reduce the risk of failure—making this a critical component of a robust and future-proof infrastructure solution.
