Sjøentreprenøren is a specialist in underwater work along the Norwegian coast, with a focus on quality, the environment and technology since 1999.

Sjøentreprenøren was established in 1999 when NCC acquired and merged Sande Diving and Hystad Dredging. The company has since developed into a player in underwater work in Norway. Based in Bergen and operating along the Norwegian coast and parts of Scandinavia, the company specialises in projects under water, including dredging, blasting, construction and inspection.
The company has grown in line with technological development and customer needs. From being a smaller player with few employees and small projects, Sjøentreprenøren has increased its capacity and range of services to handle larger assignments nationally and internationally. It has invested in equipment such as remotely operated underwater vehicles (ROVs), positioning systems and environmentally focused solutions, which have contributed to efficiency and precision in the work.
The development has also included staff through recruitment of engineers, commercial divers and skilled workers with relevant expertise. The company emphasises quality, safety and collaboration, as well as continuous learning and improvement.
The combination of experience, technology and expertise has given Sjøentreprenøren the role of a leading provider of underwater services.
Today, Sjøentreprenøren offers a wide range of services and an organisation adapted to various project sizes, with the aim of delivering safe and effective solutions under water.
Sjøentreprenøren has built a solid reputation in the trade press, including coverage in publications such as Bygg.no and other industry media. The articles highlight our expertise, quality and ability to deliver demanding marine projects with a focus on safety and sustainability. This good reputation is the result of many years of targeted work, innovation and close collaboration with customers and partners.
