As experts in offshore wind, we provide engineering and consulting services throughout the offshore wind project lifecycle. However, our primary focus areas lie within the development and pre-construction phases. 

Competent electrical engineering is critical to any electrical generation and transmission project in the areas of consent, bankability, construction, operation, maintenance and decommissioning. 

Our electrical engineering staff have an impressive record of global experience as well as in-depth technical and commercial expertise in offshore wind electrical engineering, technical studies and advisory services.  

Our Solutions

Engineering Development Services

Electrical System Design and Review 

  • Initial concept studies 
  • System design and optimisation 
  • Cost assessment and optimisation 
  • Power system simulations 
  • Cable rating analysis 
  • Array cable layout design 
  • Cable design 
  • Transmission system design 
  • Electrical calculations 

System design covers the full electrical system and includes the offshore transmission system (AC/DC), the array system, the interface at the grid interconnection point, and WTG performance. Not only can we advise on and review these systems, but we also provide design services, including offshore transmission system design, array cable layout design, and cable design. 

To maximise CAPEX savings and minimise expenses, we provide cost assessments and optimisation studies, including array layout optimisation. 

By providing initial concept studies first, clients can understand different transmission system design options such as technology, operating voltage, and number and length of circuits. We can then use cost-benefit analysis to advise which is the most optimal solution for your project (including AC and DC technology) and follow with our design services. 

We also perform power system studies and cable ratings analysis and advice as an integrated package to deliver an accurate view of system feasibility and system requirements, including cable sizes.

Cable Protection Systems and Submarine Cable Failures

Typical causes and remedies

By OWC’s Riccardo Felici and Daniele Caruso, 2022

According to 4Coffshore, around 4,600 subsea cables have now been laid and are serving offshore wind farms globally. Of the 4,600 around 10 incidents are declared annually, resulting in an average cable downtime of 100 days. In the past seven years, 90 subsea cable failures occurred totalling over EUR 350 million in insurance claims.

Safety in Numbers: Benefits of Portfolio Diversification in Renewable Energy Investment

Apr 17, 202310 min read
Owning and operating a single renewable asset, such as a wind farm, can prove to be risky for investors. Factors such as variable site conditions, seasonality (and, by extension, climate change) can all translate into an unstable and unpredictable return on investment. Those looking to enter the ring might consider diversifying their portfolio of assets in order to reduce financial risk.
