I don’t know what the acronyms you’re using mean, I’m going directly off the video you linked and what was said.[/quote]
OOD means Officer of the Deck, spoken “Officer of the Deck”.
DOOW means diving officer of the watch (though it is usually an enlisted person, senior in rank), spoken “Dive”.
COOW is spoken “Chief of the Watch”.
Also, the last guy in the chain, who sounded the alarm, also appeared to perform the dive.[/quote]
Sir, that is because you are not Qualified in Submarines. The DOOW is the one who is diving the boat.
Several things have to happen to dive the boat:
clear the bridge and close the hatch etc.
all ahead full (iirc). the helm sets this speed with the Engine Order Telegraph, which sends a signal the Engine Room; the Throttleman turns his wheel appropriately in order to let more steam out of the nuclear reactor.
rudder amidships, by default, unless the OOD said otherwise. This is performed by the Helm (sometimes yours truly).
IIRC, 20 degrees down bubble. This refers to the angle of the submarine and is controlled by the Planes watch (sometimes yours truly) on the orders of the DOOW.
open the valves to take water in the main ballast tanks. This action is performed by the chief of the watch when the DOOW tells him to do so. The COOW is not doing this of his own accord; he does what the DOOW tells him to do.
The person responsible for “reaching and maintaining ordered depth” is the DOOW. The COOW opens valves and takes on the amount of water that the DOOW tells him to admit. merely taking on this amount of water will cause the boat to go underwater, but that is not the proper procedure for a controlled dive. DOOW is required to coordinate the evolution known as submerging the submarine.
No, sir. I am correcting your interpretation, as someone who is Qualified in Submarines and qualified Helm/Planes watch, two certifications which you do not have, sir. I can’t tell you anything about STCW – you are the one who could teach me about STCW – but I can teach you about diving a submarine.
