Commercial Diving

The marine contractor offers professional commercial diving and underwater work with a focus on high quality, safety, and documentation. With extensive experience from demanding underwater projects in challenging environments, we have developed a solid knowledge base in the field. Our certified divers handle everything from inspection and maintenance to construction, demolition, and environmental work – always tailored to the project's unique needs.

Commercial diving is a specialised field encompassing many different tasks underwater, requiring strict technical competence and safety procedures. Our divers are trained to work at great depths, in confined spaces, and under conditions with strong currents and limited visibility, enabling us to deliver even the most challenging assignments.

We offer complete solutions for underwater work, including:

  • Inspection and maintenance of quays, pipelines, and structures
  • Formwork, reinforcement, and casting underwater
  • Charging of dynamite and controlled detonations
  • Bolting and securing rock and structures
  • Environmental work such as cleanup and covering
  • Nitrox diving and decompression diving for great depths

All our assignments are carried out in accordance with applicable regulations, and we thoroughly document the work to ensure traceability and quality throughout the process.

We combine experienced diving teams with specialised equipment and ROV technology to deliver precise and effective solutions. Safety is maintained through continuous monitoring of divers, the use of nitrox and decompression procedures during deep dives, as well as strict HSE routines that protect both personnel and the environment.

Our reference projects demonstrate the breadth of our expertise:

  • Andfjord Salmon: Diving down to –48 metres
  • Chamber at CCB Ågotnes: Drilling and installation of plate for BOP testing, down to –80 metres
