OWC’s dedicated team of subsea cable experts provides a comprehensive service offering to support the optimisation of subsea cable infrastructure and grid connection solutions, reducing risk of cable failure and damage, and maximising efficiency and long-term project profit.

Our services cover technical support for all types of subsea cables throughout a project and asset’s lifecycle, with expertise across the full supply chain. We offer experience in cable design (electrical and mechanical), supply, transportation, installation, and commissioning of cables and cable protection systems. The team works closely with our geoscience specialists to provide effective cable burial and route risk assessments and installation analysis. We also offer detailed custom cable routing analysis including unusual installation conditions, dynamic cable fatigue analysis, cable stability analysis, cable pulling calculations and cable lay advice.

With our in-depth knowledge, practical experience across the offshore wind farm value chain, and multi-disciplined engineering and project management expertise, OWC has significant experience as owner’s engineer on subsea cable projects, whether just for the cables scope of work or as part of the wider owner’s engineer scope of work for an entire wind farm project.

Our experience covers more than 80 projects all over the world in varying environmental conditions.

Market Challenges

As demand for renewable energy grows, so too does the demand on subsea cabling and grid infrastructure. Effective energy transmission back to shore is a critical component of a project’s long-term commercial viability.

Preparation and analysis of grid connectivity plans increasingly play a vital role in tendering and permitting processes. So too does advanced analysis and understanding of cable design and route planning to mitigate risks early on. As projects multiply, and go further and deeper out to sea, risk profiles change, and turnkey solutions for optimised subsea infrastructure are key.

Our Solutions

Our solutions support clients in addressing the increasing challenges and changing risk profile facing cable projects today. The wide range of technical services enables us to provide turnkey solutions to help clients achieve permitting success through to development, engineering and construction, and in the optimised operations & maintenance of their assets, having a direct result on the bottom line of a project.
