Chief Electrician / Electrical Supervisor

Also known as: Chief Electrician · Electrical Manager · Electrical Supervisor

Responsible for the entire high and low voltage electrical installation.

What you need to perform it

Primary qualification

  • Electrical/electromechanical engineering or STCW III/6 (Electro-Technical Officer) where the safe-manning document requires it.
  • High-voltage authorised person (management-level HV training + company appointment) for switching and isolations.
  • Ex/ATEX-IECEx competence in inspecting and maintaining equipment in explosive atmospheres (CompEx scheme as reference — indicative).

Basic STCW

  • A-VI/1
  • OPITO BOSIET

Specific courses

  • MV switching and protection: coordination, relays and testing
  • Drilling drives and VFDs (installed OEM SCR/VFD)
  • Periodic Ex inspections and classified-area register control
  • Batteries, UPS and essential supplies; blackout and black start

Indicative experience

Indicative: 5+ years in industrial/marine electrical work with MV history, and at least one hitch as an offshore electrician before the senior post.

Observations

High voltage and Ex competence are non-negotiable here: Ex findings are among the most repeated in rig audits. Progression: electrician → Chief Electrician → ETO (III/6) / electrical superintendent.

SupervisesElectricians, Electronic Technician (ET)

Owns the unit's electrical network: main and emergency generation, 6.6-11 kV switchboards, transformers, the drilling drives' VFDs and lighting/outlets in classified areas. Authorises and performs high-voltage switching, keeps the Ex-equipment register and leads the watch electricians. On a diesel-electric plant, isolation discipline is a life-critical barrier.

Typical watches

  • Day work / on call for emergencies

Key responsibilities

  • Supervision of high and low voltage electrical generation and distribution.
  • Guarantee uninterrupted supply to critical systems (drilling, DP, life).
  • Preventive and corrective electrical maintenance planning.
  • Management of insulation tests, connection and maintenance of generators.
  • Compliance with ATEX regulations in areas with risk of explosion.

Operational scope

  • Electrical panel room
  • Generation system
  • The entire MODU electrical installation
