Sjøentreprenøren specialises in the construction and rehabilitation of breakwaters and jetty that protect harbours, quay facilities, and coastal areas against waves, currents, and erosion. Our solutions are developed to withstand demanding weather conditions and contribute to safe navigation and efficient port operations. We deliver complete projects from planning and design to completion – always with a focus on quality, safety, and the environment.
A breakwater is a protective structure that shields harbours and quay facilities from waves and sea spray, while a jetty is an underwater structure made of stone or other materials often used to extend quays, establish new areas, or stabilise the seabed. Both solutions are crucial for ensuring safe and functional harbour areas.
