Question 1

According to IMCA M 103, the DP Annual Trials should verify that the vessel's DP capability matches:

Accepted Answer

The capability plots defined and proven in the DP FMEA prove-up trials

Answer

IMCA M 103 requires annual trials to confirm that actual vessel DP capability is consistent with the capability plots established during the FMEA prove-up process.

Question 2

Under US BSEE regulations, which personnel aboard a DP drilling unit operating on the US OCS are required to have formal DP training?

Accepted Answer

All bridge watch officers and anyone who may operate the DP system

Answer

Accepted Answer

Increase vigilance, notify the OIM, and prepare to execute a controlled disconnect if conditions worsen

Answer

A Yellow Alert triggers heightened monitoring, OIM notification, and readiness to disconnect — operations may continue but the DPO must be prepared to escalate.

Question 4

The primary purpose of the DP Capability Plot is to:

Accepted Answer

Show the maximum environmental conditions (wind, current, waves) in which the vessel can maintain position after the worst credible failure

Answer

The DP Capability Plot graphically shows the limiting environmental conditions within which the vessel can maintain position following the worst credible single failure.

Question 5

Which of the following changes to a DP vessel would specifically require a revision of the DP FMEA?

Accepted Answer

Addition of a new power bus tie arrangement that alters the redundancy concept

Answer

Changes that alter the power or redundancy concept — such as a new bus tie arrangement — change the failure mode logic and must trigger an FMEA revision.
