Landfall

Landfall is a crucial step in the transfer of power and communication between sea and land. The marine contractor is an expert in landfall for both high-voltage cables and communication cables. With extensive experience from demanding projects such as Melkøya, Kårstø, Kolsnes and Bokn, we deliver customised solutions that ensure stable and environmentally friendly supply of energy and data.

Our specialised expertise in landfall enables us to handle complex projects where precision, safety and environmental considerations are central. Landfall processes include everything from underwater excavation, horizontal drilling and pipe laying on the seabed.

One of our most central projects is the landfall at Melkøya. Here, we prepare for tunnel and landfall for power cables that will supply the LNG plant with electricity from land. This is part of the Snøhvit Future project, which aims to significantly reduce CO₂ emissions through the electrification of energy production. Projects like Melkøya illustrate how innovative technology and sustainable solutions work hand in hand to meet future energy needs.

We have handled challenges such as:
Landfall at Kårstø and Kollsnes with safe and efficient solutions
These projects demonstrate how we deliver cable systems on demanding routes. We have handled challenges such as:

  • Different ground conditions
  • Large tidal differences
  • Strict environmental requirements

All projects are carried out with a focus on HSE, thorough risk assessments and good quality assurance. This gives customers the assurance that the work complies with regulations and affects nature as little as possible.

The marine contractor offers a wide range of services tailored to different types of shore landings:

  • Underwater excavation and pipe laying for power cables and fibre
  • Underwater blasting
  • ROV and diving services

Our project management works closely with the client and consultants to optimise solutions based on local conditions and the customer's needs. We have extensive experience with integrated projects where multiple elements – such as drilling, pipe laying and cable installation – are carried out in parallel to save time and ensure the best possible result.

Sustainability and the environment are central to all our deliveries. We use modern equipment that minimises impact on nature and ensures that work processes have a low carbon footprint. Our environmental policy governs all work, from material selection to implementation and follow-up checks.

The marine contractor guarantees top quality and safety for all shore landing, cable and pipe projects, whether it concerns Melkøya, Kårstø, Kolsnes, Bokn or other locations in the country. With us as a partner, you get a safe, efficient and forward-looking solution for cable installation from sea to land.
