During a DP incident, the vessel experiences an unexpected drive-off. What is the first action the OOW should take?
Answer: Engage manual override and take direct control of the vessel
When a drive-off occurs, the OOW should immediately engage manual override to take direct control and prevent further uncontrolled movement.
Which document defines the minimum safe separation distances between a DP vessel and a subsea structure?
Answer: The vessel's Station Keeping Operations Manual (SKOM)
The Station Keeping Operations Manual (SKOM) specifies operational limits including minimum safe separation distances from subsea structures.
What does a 'worst case failure' (WCF) analysis determine in DP operations?
Answer: The single failure that causes the greatest loss of position keeping ability
Worst case failure analysis identifies the single failure mode that causes the greatest degradation of the vessel's position keeping capability.
When should a DP trial be conducted on a vessel returning from drydock?
Answer: 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.
What is the purpose of a 'red zone' designation in a DP diving support operation?
Answer: It identifies the exclusion area around the dive spread where vessel movement is critically restricted
The red zone defines the critical exclusion area around the dive spread where any vessel movement could endanger divers.
A DP operator notices the vessel is experiencing repeated thruster failures in rough weather. What action should be taken?
Answer: Conduct a risk assessment and consider suspending operations
Repeated thruster failures in adverse weather require a risk assessment, and operations should be suspended if the failure pattern indicates a safety risk.
What is the significance of a 'yellow alert' on a DP vessel during well intervention operations?
Answer: It warns that conditions are deteriorating and operators should prepare for possible disconnection
A yellow alert indicates deteriorating conditions and signals personnel to prepare for potential emergency disconnection from the wellhead.
