Your DP2 DSV has been on station for two days running ROV survey operations. The dive team now wants to put divers in the water. The lead DPO suggests skipping the consequence analysis test 'since we've been here for two days and everything is clearly working fine.' As master, is the lead DPO correct?

A. The test only needs to be run once per worksite visit, regardless of changes in operational scope

B. The test is optional if there have been no system alarms in the previous 24 hours

C. Yes — two days of stable operations with no faults is a valid substitute for a formal consequence analysis test before the dive

D. No. Two days of successful ROV operations does not prove the vessel can maintain position after the WCF in the current conditions at this moment — conditions change, thruster configurations change, and the DP loading profile for a diving operation (which may require different heading or reference configuration) may be different from the ROV operation. The consequence analysis test must be run before divers enter the water, as the abort criteria change entirely once divers are in the water

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
