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

Correct Answer: Option B — The officer in charge of the engineering watch shall notify the chief engineer without delay when No.2 SSDG repairs are complete and the generator has been prepared for testing.

Night orders are reserved for non-routine operational directives, such as requiring immediate notification upon completion of specific auxiliary diesel generator repairs and readiness testing.
