ABOUT THE ROLE
The HV Manager holds senior technical authority for all high-voltage plant, equipment, and operations at Hai Long. Reporting to the O&M Manager, the role owns the site's Electrical Safety Rules and Switching Authority regime, and is accountable for the structure, competence, and legal compliance of the SAP/AE/CE authorisation chain across the project.
The role works closely with the wider O&M organisation on all HV-dependent maintenance, outage,
and grid-interface activity, and carries direct accountability for HV readiness through the EPC-to-
O&M transition and into steady-state operation.
KEY RESPONSIBILITIES
In this capacity, you shall take on a broad range of tasks, including but not limited to the following:
- Own and maintain the site's Electrical safety-rules framework, consolidating the SAP/AE/CE authorisation chain into a single, coherent structure that is current, competent, and legally compliant.
- Act as the Authorising Engineer, chairing authorisation panels and assessing personnel for appointment, renewal, suspension, or withdrawal of authorisations based on competence, experience, and demonstrated capability.
- Act as the senior technical authority for all HV plant, equipment, and switching operations across the site, including sign-off on HV single-line-diagram changes and new asset additions during any works.
- Oversee any condition-monitoring contracts for HV assets (transformers, switchgear, cabling), holding contractors to agreed scope, KPIs, and reporting standards, with budget accountability for the programme.
- Design and deliver the SAP training/competence-development programme, building authorisation bench strength beyond the current holders with clear voltage-band progression (e.g. 66kV → 230kV).
- Build-up, lead and develop the HV team, including SAP’s and Control Engineers.
- Support the Chief Technicians with the grid operator/TSO interface on HV connection, outage planning, and switching coordination.
- Lead incident investigation, root-cause analysis, and statutory/regulatory notification for HVrelated faults, outages, and safety events.
- Provide HV technical input to the O&M Manager and wider O&M organisation on maintenance strategies, operational risk, outage planning, commissioning activities, contractor management, and long-term asset performance.
- Own HV documentation; safety rules, permits-to-work, switching schedules, and drawings - keeping them audit-ready at all times.
- Represent HV readiness at the project's Operational Readiness Review gates ahead of handover to O&M.
