About the course

This foundation level course details each phase of the lifecycle of subsea cables used in offshore wind power applications, power interconnectors between oil and gas assets, and transnational networks. 
Discussing common failures seen over recent years, the tutor will provide learners with knowledge on how to identify, solve and mitigate issues to avoid down time and costly subsea repairs. This course covers understanding of risk management and the root causes of failures, as well as providing latest best practice and standards.
Health and safety considerations are also covered with safety moments demonstrating the need for continuous improvement in order to protect an ever increasing workforce during a risky operation/activity.
This course is ideal for installation contractors, engineers and project managers, as well as insurance and investment professionals looking to better understand the risk of assets they are insuring or investing in.


Learning outcomes

  • Select the correct route for a cable
  • Demonstrate ways to optimise cable protection 
  • Compare a variety of installation methods
  • Use worked examples to apply lessons learned to your projects
  • Identify methods to reduce the risk of failure

Mark Kinder, Technical Director, Kintech Energy Ltd

  The Jee Subsea Power Cables course is an excellent training programme which provides valuable insights into the challenges faced by cable engineers on an offshore wind farm project. It's content serves both as a useful introduction to submarine cables for those new to the industry and to increase the knowledge of experienced cable engineers alike.
