About the course

This 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 coach you on how to identify, solve and mitigate issues to avoid down time and costly subsea repairs. This course will help you understand risk management and the root causes of failures, as well as bringing you up-to-date on latest best practice and standards.

Drawing on practical examples and case studies, this course will walk you through each stage of the lifecycle of a cable – from determining a cable route and burial methods, to design and installation, through to structure connections and landfalls. 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.
