Frequently asked questions

High-voltage (HV) jointing offshore refers to of connecting high-voltage cables—such as those linking wind turbines to substations or export cables—to ensure efficient and secure power transmission in marine environments. This involves installing joints and terminations designed to withstand the challenging offshore conditions.

The service includes joining turbine-to-base cables, inter-array cables that connect multiple turbines, and export cables that deliver power from the wind farm to the onshore grid.

The service reduces the likelihood of faults and failures by employing proven installation techniques, utilising quality materials, and adhering to strict industry standards. Fewer failures mean lower repair costs, minimised downtime, and a more stable power supply.

Offshore-optimized procedures are tailored to the marine environment. These methods reduce vessel time at sea, streamline logistics, and ensure consistent, efficient installation—ultimately lowering operational costs and improving project timelines.

Long-term reliability is achieved through careful material selection, expert installation teams, and strict quality control and safety measures. These factors combine to create joints and terminations that ensure stable operation over the project’s lifespan.

Yes. Every offshore wind project is unique, and the service can be tailored to specific conditions, cable types, technical requirements, and installation methodologies to deliver the most effective, safe and cost-efficient solution.

By minimising the occurrence of cable faults and the need for repairs, the service helps reduce long-term maintenance expenses. This not only optimises the budget but also enhances the overall profitability and performance of the wind farm.
