As a chief engineer, which of the following instructions would most appropriately be written into the chief engineer's night orders due to the non-routine nature of the special instruction?

Correct Answer: Option A — The OICEW shall notify the chief engineer without delay when the No.1 main feed pump repairs are complete and it is ready to be put back into service.

Non-routine evolutions, including post-repair testing and reintegration of critical equipment like main feed pumps, are formally mandated via the Chief Engineer's night orders.
