A DP vessel's Annual DP Trials must be witnessed and documented by which authority to satisfy class requirements?

Under the NOPSEMA guidelines for DP operations in Australian waters, what is required before a DP vessel commences a critical DP operation?
Answer: A vessel-specific Operations Manual with DP risk assessment signed by the DPO
NOPSEMA requires that a documented DP Operations Manual and risk assessment be in place and accepted by the responsible DPO before critical operations commence.
The 'WSOG' document used during DP operations on drilling vessels primarily defines:
Answer: Well-specific operating guidelines including MODU disconnect criteria
The Well-Specific Operating Guidelines (WSOG) define the operational parameters, exclusion zones, and disconnect criteria specific to each well for the MODU.
Under IMCA's DP incident reporting guidance, a 'Loss of Position' is formally defined as uncontrolled vessel movement of more than:
Answer: The agreed exclusion zone or operational radius as defined in the ASOG
A Loss of Position is defined as movement beyond the exclusion zone or operational radius established in the Activity Specific Operating Guidelines (ASOG).
When a DP vessel's gyrocompass reading diverges significantly from the backup heading reference, the DPO's first action according to best practice should be:
Answer: Accept the reading most consistent with external references and investigate the discrepancy
The DPO should cross-check all available heading references and accept the most credible value while investigating the cause of the divergence before escalating.
ISM Code requirements mandate that DP vessel operators must include DP-specific content in their:
Answer: Safety Management System (SMS) including procedures for DP operations and emergencies
