✍️ Sample DPO Questions & Answers

1. What is scope creep in DPO project management?
✓ Uncontrolled scope expansion without adjusting time, cost, or resources

Scope creep adds requirements without formal evaluation, causing schedule delays and budget overruns.

2. What is the primary function of a gyrocompass in a DP system?
✓ Provide a stable heading reference independent of magnetic variation

A gyrocompass provides a true north heading reference that is unaffected by magnetic variation or deviation, making it essential for accurate DP heading control.

3. A quality review of DP incident reports over 12 months reveals that 60% of excursions occurred during watch handovers. The most effective systemic quality improvement would be to:
✓ Implement a structured handover checklist and require a stabilization period before the outgoing DPO leaves the console

A structured handover checklist with a stabilization period directly addresses the root cause by ensuring situational awareness is fully transferred before the handover is complete.

4. According to IMCA M 166, what is the recommended minimum number of independent position reference systems for a DP Class 2 operation?
✓ Three

IMCA M 166 recommends a minimum of three independent position reference systems for DP Class 2 operations to ensure reliable position data.

5. Which thruster fault type is most likely to cause a sudden unplanned vessel rotation in DP?
✓ A thruster delivering full thrust in the wrong direction (runaway/hardover)

A hardover or runaway thruster delivering maximum thrust in an unintended direction creates a large moment that can cause rapid, uncontrolled rotation of the vessel.

6. When should a DP trial be conducted on a vessel returning from drydock?
✓ Before any DP operations commence, regardless of modifications

A full DP trial must be conducted before resuming DP operations after drydock to verify all systems function correctly.
