As the global energy sector accelerates its transition to offshore wind and interconnector projects, subsea power cables have emerged as a critical, yet vulnerable component of this infrastructure. These cables, often buried beneath the seabed, are responsible for transmitting electricity from offshore turbines to onshore grids. However, their complexity, exposure to harsh marine environments, and limited repair options make them a significant source of technical and financial risk for developers and insurers alike.
At the Asia Power Forum 2025 in Singapore, forensic investigator Dr Hugh Martindale took the stage to shed light on these challenges. In his presentation “Subsea Power Cables in Offshore Wind and Interconnectors: Insurance Claims, Causes and Key Risk Issues”, Hugh explored the growing demand for offshore wind, the consequences of cable failure, and the wide array of failure modes. These include anchor damage, thermal breakdown, manufacturing defects and sabotage. He emphasised the urgent need for industry-wide collaboration, improved design standards, and investment in supply chain resilience to mitigate escalating business interruption costs and repair delays.
With a background in forensic engineering and mechanical failure analysis, Hugh is a recognised expert in subsea cable investigations, specialising in diagnosing complex failures in offshore energy systems. His expertise spans cable design, installation, and operational risks.
