Subsea power cable certification services for offshore wind
Project certification delivers maximum stakeholder confidence for subsea power cables and their cable protection systems
Harsh marine environments coupled with the number of cable interfaces at each foundation location, introduces unique challenges previously unseen by the offshore wind industry. Although subsea power cables typically account for a small portion of the total amount of investments in offshore wind farms, when they fail, the impact is incredibly significant. Research from Lloyd Warwick, an international specialist in loss adjustment and claim management, has found that power cable failures are to blame for around 83% of all offshore wind related financial losses and insurance claims.
This is why stakeholders want reassurance that all steps have been taken to minimize risk and maximize the chances of a successful subsea cable project. Project certification is the most trusted route to deliver stakeholder confidence. By evaluating site specific conditions and certifying the project’s subsea cables and equipment against an accepted standard, certification statements show that the risks have been accounted for and minimized as much as possible
Risk mitigation through certification
Project certification based on DNV’s service specification DNV-SE-0190 offers both modular and comprehensive approaches to certify the main assets within the wind power plant, i.e., wind turbines, substations, and subsea power cables. Subsea power cables can also be covered together with wind turbines and substations in DNV’s Project Certification services or certified separately.
DNV offers a complete service for certifying subsea power cables against our comprehensive standard, DNV-ST-0359. This document provides the most comprehensive technical reference suite for subsea cables available in the industry. In addition, DNV also offers pre-certification services meant to provide early confidence (risk mitigation) on a range of topics such as site conditions, design methodology, technology qualification, as well as many others.
The modular certification approach, as detailed in DNV-SE-0190, covers all development levels from early concept to commercial project and includes assessment of:
- Design basis
- Design
- Manufacturing
- Testing
- Transport and installation
- Commissioning
Audience
Although project certification is primarily delivered to project developers, our certification services can be tailored for cable/equipment suppliers and designers as well.
