According to IMCA M 103, the DP Annual Trials should verify that the vessel's DP capability matches:
Answer: The capability plots defined and proven in the DP FMEA prove-up trials
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.
Under US BSEE regulations, which personnel aboard a DP drilling unit operating on the US OCS are required to have formal DP training?
Answer: All bridge watch officers and anyone who may operate the DP system
BSEE NTL 2009-G22 requires all personnel who may operate or supervise the DP system — including relief DPOs — to hold recognized DP training certification.
In a DP operation, the term 'WSOG Yellow Alert' condition means the DPO should:
Answer: Increase vigilance, notify the OIM, and prepare to execute a controlled disconnect if conditions worsen
A Yellow Alert triggers heightened monitoring, OIM notification, and readiness to disconnect — operations may continue but the DPO must be prepared to escalate.
The primary purpose of the DP Capability Plot is to:
Answer: Show the maximum environmental conditions (wind, current, waves) in which the vessel can maintain position after the worst credible failure
The DP Capability Plot graphically shows the limiting environmental conditions within which the vessel can maintain position following the worst credible single failure.
Which of the following changes to a DP vessel would specifically require a revision of the DP FMEA?
Answer: Addition of a new power bus tie arrangement that alters the redundancy concept
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.
Under SOLAS Chapter II-1, a DP vessel's emergency source of electrical power must be capable of supplying which DP-related loads?
Answer: Navigation lights, internal communications, and DP control systems for a minimum period per SOLAS requirements
SOLAS requires the emergency generator to power essential services including navigation aids and control systems (which encompass DP control electronics) for the SOLAS-specified minimum period.
A DPO discovers that the vessel's DP system has been operating in 'Degraded Mode' (with one DP computer offline) for the past 6 hours without entry in the DP log. The correct response is:
Answer: Make a retroactive log entry, inform the Master, and initiate investigation per the SMS non-conformance procedure
Failure to log a significant system status change is a non-conformance under the SMS; the DPO must correct the record, notify the Master, and raise a formal non-conformance report.
