A certificated officer qualified to operate and monitor a vessel's dynamic positioning system during offshore operations.
In practice
DPOs work primarily on offshore support vessels, drill ships, pipe-lay vessels, crane barges, and shuttle tankers, where precise station-keeping is essential for safe operations near subsea infrastructure and production platforms. Under STCW chapter V, officers on offshore supply vessels may have type-specific training requirements in addition to the standard OOW certificate. IMCA (International Marine Contractors Association) publishes detailed guidance on DP operations, competence assurance, and incident investigation. Maintaining a DP system in class-approved condition requires regular trials, annual surveys, and the logging of all DP incidents in the vessel's FMEA (failure mode and effects analysis) trial records.
Regulatory detail & full definition
A Dynamic Positioning Operator (DPO) is a certificated officer qualified to operate and supervise a vessel's dynamic positioning system — a computer-controlled system using thrusters and propellers to maintain the vessel's position and heading automatically, without anchoring. The Nautical Institute administers the internationally recognised DP training and certification scheme, which comprises basic and advanced simulator courses plus a structured sea service log, leading to DP Operator certificate recognition by major oil companies and offshore operators.
