DPO Safety Protocols & Emergency Procedures 3

Question 1

Which IMO resolution provides the guidelines for vessels with dynamic positioning systems?

Accepted Answer

IMO MSC/Circ.645

Answer

IMO MSC/Circ.645 provides the guidelines for vessels with dynamic positioning systems and is the primary international reference for DP vessel classification.

Question 2

During emergency disconnect from a subsea wellhead, which sequence is correct?

Accepted Answer

Close BOP, pull emergency release tool, move vessel off location

Answer

Emergency disconnect requires closing the BOP first to secure the well before the emergency release tool is pulled and the vessel moves off location.

Question 3

What is the role of the 'Consequence Analysis' function in modern DP control systems?

Accepted Answer

It continuously models the vessel's ability to maintain position after a simulated worst case failure

Answer

Consequence Analysis continuously runs simulations to show whether the vessel can maintain position after a worst case failure, providing real-time go/no-go guidance.

Question 4

A DP vessel's footprint monitor shows the vessel has drifted to the edge of its allowable excursion limit. What should the DP operator do?

Accepted Answer

Alert the person in charge and consider activating the emergency response plan

Answer

Reaching the edge of the excursion limit is an emergency trigger requiring immediate notification of the person in charge and activation of emergency procedures.

Question 5

What does 'heading critical' mean in DP operations near a fixed installation?

Accepted Answer

The vessel's heading must be maintained within a specific range to prevent contact with the installation

Answer

Heading critical means that deviating from a specified heading range risks the vessel making contact with the nearby fixed installation.
