Demolition

Sjøentreprenøren is a leading player in underwater work and has extensive experience with the demolition of navigational markers, concrete foundations, and other marine structures. We offer complete solutions for the removal of installations at sea – from planning and design to execution and cleanup. Our goal is to deliver safe, efficient, and environmentally friendly services that meet all quality and safety requirements.

Specialists in demanding underwater operations

Underwater demolition requires precision, expertise, and the right equipment. Our divers and machine operators are certified professionals with solid experience from complex projects in ports, shipping lanes, and quay facilities. We use modern methods such as underwater sawing, chiselling, and blasting, adapted to the local conditions. This ensures that the work is carried out with minimal impact on surrounding structures and the marine environment.

Effective and safe execution

Safety is always our focus. We follow strict procedures and applicable regulations to protect both personnel and the environment. Our solutions are developed to reduce risk and ensure a safe workplace, even under demanding conditions such as strong currents, poor visibility, or great depths.

Environmental considerations and sustainability

We take environmental responsibility seriously. When demolishing navigational marks and foundations, we ensure proper handling of waste and materials, so that everything is delivered to approved facilities. Our work is always planned with the aim of minimising impact on nature and preserving the marine ecosystem.
