โœ๏ธ Sample DPO Questions & Answers

1. What is scope creep in DPO project management?
โœ“ 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?
โœ“ 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:
โœ“ 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?
โœ“ 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?
โœ“ 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?
โœ“ 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.
