Recently, our team completed a package of specialist 66kV and 220kV cable works offshore on behalf of Equans through challenging weather conditions.
Our specialist cable jointers supported the project with cable pulling, routing, cleating, Pfisterer jointing, HV/MV terminations into 66kV and 220kV GIS, Brattberg seal installation, and full HV testing to IEC standards.
All activities required close coordination with multiple OEMs and strict compliance with DNV, BS, IEC and ENA requirements.
Offshore conditions introduced tight operating limits on temperature, wind and humidity, alongside confined routing within multi‑voltage OSP structures.
Through careful planning, clear communication, and specialist tooling, the team executed every stage safely, efficiently and to the highest technical standard.
The result: a fully compliant, high‑integrity cable system installation delivered smoothly on behalf of Equans, reinforcing reliability, strengthening the wider offshore programme and maintaining client confidence.
