A Petroleum Inspector Supervisor leads the team performing quantity and quality inspections of petroleum products — at terminals, refineries, ports, or pipelines — owning inspection protocols, certification, and the documentation that follows.
Days tend to revolve around the inspection schedule and the field team running it. You're managing assignments across sites, reviewing inspection reports for accuracy, handling escalations from clients or operators, and partnering with lab on quality testing. Off-hours coverage is common given vessel and tank schedules.
The collaboration is wider than expected. You're working with clients (often traders or terminal operators), lab staff, regulators, and vessel or terminal operations. Friction usually lives in the gap between operational tempo and the inspection protocols that protect both client and inspector liability.
People who tend to thrive enjoy field-team management with technical, regulatory, and client-service angles and don't mind irregular hours. If you need an office role, distance from terminal environments, or fewer client escalations, the role can wear thin.
