A charterer's schedule would require deferring a maintenance task on safety-critical equipment that has now reached its due date. How should the Master weigh commercial schedule pressure against the maintenance requirement?

A. The safety-critical maintenance requirement should take priority — commercial schedule pressure is a recurring theme behind real maintenance-related incidents, and a Master's independent safety judgement, informed by the actual criticality of the specific task, should not be overridden by charter party schedule pressure alone

B. The decision should be made by the charterer, since they bear the commercial consequence of any delay

C. Safety-critical maintenance can be deferred indefinitely as long as the equipment continues to function without an obvious fault

D. Commercial schedule commitments should always take priority over maintenance scheduling, since charter party penalties have direct financial consequences

A. A PMS eliminates the need for any reactive/breakdown maintenance once fully implemented

B. To ensure equipment is maintained at intervals based on manufacturer recommendation, class/statutory requirement, and operational criticality before it fails, shifting maintenance from purely reactive (fix it when it breaks) to proactive — with the added benefit of providing a documented, auditable history of what has been done and when

C. The PMS exists purely to generate paperwork for class surveys, with no real operational safety function

D. A PMS is only relevant to engine room equipment and has no application to deck or bridge equipment

A. All equipment should receive identical maintenance treatment regardless of its function or consequence of failure, for simplicity

B. Criticality assessment is only relevant to DP vessels and has no application to conventional vessels

C. Equipment is assessed for criticality based on the consequence of its failure (safety, environmental, or operational impact) and how quickly that consequence would materialise — safety-critical equipment with no redundancy (e.g. steering gear) warrants tighter maintenance intervals and guaranteed spares availability compared to equipment whose failure has minimal or easily-managed consequence

D. Criticality is determined solely by the original purchase cost of the equipment, not its function or failure consequence
