  • Offshore Commissioning Support - Assist commissioning teams with energisation preparation, functional testing, fault-finding, and system verification on offshore platforms.
  • Offshore Electrical Safety - Work under offshore HV safety rules, isolation procedures, LOTO systems, and marine permit-to-work processes.
  • Platform Operations - Support HV activities across offshore substations, converter platforms, and export cable interface points.
  • Documentation & Reporting - Complete offshore test sheets, inspection records, switching logs, and commissioning documentation to project standards.
  • Fault Response Offshore - Support troubleshooting and corrective actions on HV plant during offshore construction, commissioning, and early operations.
  • Contractor & OEM Coordination - Interface with offshore contractors, marine crews, and package teams to ensure safe and compliant execution of HV tasks.
  • Quality Assurance Offshore - Verify installation quality, cable terminations, torqueing, insulation resistance results, and readiness for energisation.
  • System Readiness Offshore - Support offshore walkdowns, punch-list closure, and pre-energisation readiness reviews.



Required Qualifications & Experience

  • Recognised HV Competency - Formal HV switching/authorisation or equivalent HV training.
  • Offshore HV Experience - Proven experience working offshore on HV systems within offshore wind, offshore substations, offshore platforms, or marine energy infrastructure.
  • Technical Knowledge - Strong understanding of offshore switchgear, transformers, protection relays, cable terminations, fibre integration, and SCADA interfaces.
  • Offshore Safety Systems - Experience working under offshore electrical safety rules, LOTO systems, and marine permit-to-work procedures.
  • Documentation Skills - Ability to produce accurate offshore test records, inspection sheets, and commissioning documentation.
  • Communication - Clear English communication skills, both written and verbal.
  • Offshore Certification - Valid GWO, offshore medical, and marine survival certificates.
  • Right to Work - Must hold valid work rights suitable for UK offshore deployment.
