Vetting — SIRE Machinery Spaces Practice Questions

A. The Chief Engineer's Standing Orders are required to directly contradict or override the Master's standing orders whenever the two roles disagree

B. The Master's standing orders address bridge/navigational command and control, but engine room management has its own distinct technical decision points (UMS entry procedures, critical alarm response, defect handling, bilge/sludge/incinerator supervision) that fall within the Chief Engineer's specific area of responsibility and require department-specific guidance the Master's orders are not structured to cover in that depth

C. This requirement applies only to vessels operating with continuously manned machinery spaces, never to UMS-capable vessels

D. Chief Engineer Standing Orders exist purely as a duplicate administrative requirement with no content distinct from the Master's standing orders

A. This exception applies only to deviations occurring during night orders, never during day orders

B. Daily Orders are written based on the anticipated timing of operations, but real port/voyage circumstances genuinely change after the orders are written — penalising the crew for sensibly adapting to a real operational change (rather than ignoring the orders through poor planning or carelessness) would punish good judgement and could create an incentive to rigidly follow outdated instructions even when conditions have clearly changed

C. This exception means Daily Orders compliance is never actually checked or enforced in practice

D. Any deviation from Daily Orders is automatically acceptable regardless of the reason, with no distinction between genuine circumstance changes and simple non-compliance

A. UMS entry procedures exist purely to restrict access for security reasons, unrelated to personal safety monitoring

B. Dead man alarms are required only for entry into machinery spaces that have never previously been classified as UMS-capable

C. Entry during UMS periods carries identical risk to entry during a manned watch, making a separate procedure unnecessary in principle

D. During UMS, there is no one else routinely present in the space to notice if a lone person entering becomes incapacitated — the dead man alarm and communication procedures exist specifically to compensate for the absence of the passive safety net that a manned watch normally provides, addressing a risk that simply does not exist in the same way when the space is continuously staffed
