Statistically, shit happens beween midnight and 0600, usually in bad weather.
Always inform the Bridge before stopping propulsion or generators, you may stop the fire spreading but run out of control into an LNG tanker or a passenger ship or a pointy rock.
Bridge have to assess BOTH the Fire and Navigation hazards to decide which has priority, relying on information from the Engineers on the state of the fire, how long they can keep the screw turning etc.
Even keeping the screw going for a few minutes may enable them to avoid a collision or pull out of a main channel to somewhere they can drop the pick relatively safely.
Big Pete's point is well taken but I think I know where JJ is going with this.
Hypothetically, maybe in the eyes of the law, in an emergency situation, when the Captain is not on the Bridge the Mate on watch is "In Full Command" of the vessel for the duration of his or her watch until relieved by the Captain or another Officer that has the Bridge as his or her Emergency Station. Likewise the Engineer on Watch is in "Full Command" of the Engine Room for the duration of his or her watch until relieved by the Chief or another Officer that has the Engine Room Control Position as his or her Emergency Station.. The Officers of the Watch are therefore responsible for making the critical decisions at the onset of an emergency situation, under the guidance of the Captain and or Chief, with respect to immediate navigational decisions and machinery operations until relieved. This responsibility of the Officers on Watch doesn't relieve the Captain or Chief of their ultimate Command responsibility but does buy time when every second counts.
Now in this era of Procedure Manuals and Check Lists for just about everything including CYA protection. Guidance for these critical decisions ideally are supposed to be detailed out in documents Everyone
is obliged to read and signs off on when first joining a vessel and re-familiarize themselves with on a regular basis and through practice during drills. Namely the "Captain's Standing Orders or Bridge Emergency Procedure Manual, Emergency Situation Voyage Plan Protocols and Captain's Night Order Book", along with the "Chief's Standing Orders, or Engine Room Emergency Procedure Manual and Chief's Night Order Book".
