During a crew handover, an incoming lead DPO asks for the latest DP trial results to understand the vessel's current FMEA-proven capability. The outgoing master says the trials were done six months ago and the report went to the owner's technical department — the DPOs on board have never seen it. As the incoming master, is this satisfactory?

A. Yes — annual DP trial results are technical documentation for the owner, not operational information for DPOs

B. DPOs only need to know the trial pass/fail result, not the detailed findings

C. No — the DP trial report documents which failures the vessel can actually survive, which components have known issues, and what the real WCF is under current conditions. DPOs cannot effectively operate the DP system or make ASOG decisions without understanding what the trials actually proved. The master must ensure DPOs have access to and are briefed on the trial results as part of vessel familiarisation

D. The DP system manufacturer's documentation is sufficient — trial-specific results add no operational value

A. Approve it with the condition that it is documented in the DP logbook as a controlled deviation

B. Approve the closed bus operation — a 45-minute delay causes significant commercial harm and the risk is manageable

C. Seek the vessel manager's written approval before deciding — the decision is above the master's authority

D. Decline to approve closed bus DP operations inside the field. The 45-minute delay is a scheduling cost; a common cause failure on closed bus inside the field is a safety event with consequences potentially including total loss of DP, collision with the installation, and environmental damage. Commercial pressure is not a safety justification. The master's accountability to the ISM Code and the SMS cannot be commercially overridden

A. Verbal ASOG limits agreed with the installation representative are acceptable under IMCA M109

B. Prepare a retroactive ASOG dated from the start of the operation to close the documentation gap

C. If the operation completed without incident, there's no further action required — the verbal limits clearly worked

D. Report the finding to the master, raise it through the SMS non-conformity process, and ensure a formal ASOG is in place before the next DP operation. The absence of a signed ASOG means the operation ran without the agreed, documented limits that protect the vessel, client, and crew — if an incident had occurred, liability and insurance implications would have been significant. Completing without incident does not mean the risk was acceptable
