Company History

DeepOcean Group Holding (DeepOcean) was established in May 2011 after the successful completion of the restructuring of its former parent company. DeepOcean is the parent company of the subsea services company DeepOcean AS and the cable lay and trenching company DO 1 UK Ltd.

DeepOcean offers the following five main service lines: (i) Inspection, Maintenance and Repair (IMR) including pipeline inspection, (ii) Seabed Intervention (incl. trenching), (iii) Subsea Installation (incl. SURF), (iv) Survey and Seabed-mapping and (v) Decommissioning.

DO 1 UK Ltd., formerly known as CTC Marine Projects Ltd., was established in 1993. Its initial core business was the provision of fibre optic cable lay and seabed intervention solutions for the global telecommunication market. Later, the company diversified and added cable lay and trenching services for the oil & gas, offshore renewables and interconnectors industries.

DeepOcean AS was established in 1999. It is founded on the provision of high quality equipment and subsea services combined with a team of highly experienced personnel with knowledge of deepwater operations. DeepOcean now has the track record and experience to take on deepwater assignments anywhere in the world.

Late 2016 Funds advised by Triton became the largest shareholder of DeepOcean. The Triton funds invest in and support the positive development of medium-sized businesses headquartered in Northern Europe, Italy and Spain.
