2:26 honestly i would have just assumed they were interlocked such that you cant open up the next one until the one behind you has been closed and or a timer
I dotn think people appreciate the strength of power actuated watertight doors especially when they slam closed in a emergency they can kill and they have killed and seriously injured,
I've always been really anal about holding onto the handles while going through. Saw one slip with a crewmate few years ago and activate while he was going through. Scared the shit out of me.
Wow, this is an excellent video. May I request you to create a video on Propeller and Shafting Operation, maintenance and overall internal mechanism. Thank you for sharing this video.
What if in the bridge of the ship they switch the master switch and someone in the bottom of the ship cross the watertight doors and get locked inside floating room what happens when then
It's required that area's with remote or automatic closing watertight doors have an alternative exit. Also the doors can be operated locally so a person can open it to save their life. Most remote doors will then close again automatically shortly after.
@@carlmanvers5009 Yes they can be opened locally (they should only be opened if no alterative route is available and the bridge commanded the doors closed). At the door, the switch must be held to the 'open' position. If there is hydraulic power the door will open. Doors usually have enough power locally to close open then close again if the ships power is lost. If there is no power from the ship or the doors local power is depleted, then it can be pumped open by holding the switch to open and cranking the pump until the door is open. Then from the other side of the door you will hold the switch in the open position until you cross through the door. Once you release the open switch the door will close automatically if the bridge master switch is still set to doors closed. If the door was pumped open manually then the action of pumping the door will sufficiently charge the hydraulic accumulator to reclose the door once the open switch is released.
They did the issue with the titanic was that too many compartments where breached and the water tight compartments did not extend high enough - the water ended up flowing over the top to the next compartmetn as that part of the ship was pulled down by the extra weight of the water.
3:35 i'll be honest im more concerned about the notion of a ship being built in such a way that a single water tight door being left open can sink a ship ... i mean if nothing else 1 no two compartments flooding alone should be able to sink your ship .. if it can you need more and smaller compartments and 2 i would hope there at least enough pumping capacity on your ship to be able to match the flow that could conceivable come through an opening the size of one water tight door
The Titanic was designed to float if the first or last 4 compartments were flooded, or if any combination of 2 compartments flood. The first 6 compartments were flooding after the collision, the water tight doors and compartments slowed the sinking but the damage was too extensive for the ship to float. As water entered the ship the additional weight caused a forward list and water could bypass bulkheads by over topping them. With only 4 compartments flooded the ship would have remained buoyant enough that water would not over top subsequent compartments.
Titanic was afloat perfectly fine, and was believed to be unsinkable, but it ended up striking an iceberg, I believe they were going around 22 knots but possibly less. The Titanic struck an iceberg because the lookout crew could not access the binoculars, and some believe that if Captain Smith and his crew did not try to turn to avoid the iceberg, they’d have a higher survival chance. The iceberg breached the side and more compartments were exposed than what it was designed to hold. Once the compartments started filling, the bow sank down as if the whole ship was leaning over. Later, the ship was almost fully tilted and the bow could not handle the stress of the stern, so the ship snapped in half. The bow was still connected to the stern so it brought the stern down and eventual separated. Titanic was very tragic, even I am obsessed with the history. Hope you learned something new! 👍
The major problem with the kind of thinking demonstrated in this video is the assumption that everyone knows what they are doing, have received full training and retained all the information they were given during that training. That is simply unrealistic and unobtainable and ignores several basic human and societal realities which are: 1 People are stupid, say, do and perform stupid acts with out thought or consideration 2 People are incompetent 3 People are lazy 4 People and especially groups of people, are disorganised and shambolic. When 1, 2, 3 and 4 are taken into consideration the ideals in this video are a total nonsense especially around the expectations in this video that all the crew will know what they are doing. MOST IMPORTANTLY - when 1, 2, 3 and 4 are taken into consideration with respect to any training the crew may be given, the problem is twice as bad. The training will not be full, complete and very probably, not given by somebody qualified to train anybody else anyway because they themselves were never properly trained. The most dangerous aspect to the design philosophy in this video is the operation of these doors with human interaction. The doors will not be kept closed because of the annoyance this creates. But of course no ship operator is going to admit to that because of the productivity costs associated with the massive delays opening and closing these doors constantly will incur. So, like the door designers, they just lie and pretend the doors are being operated correctly and kept closed while at sea. Because if the worst happens and the ship ends up on the bottom, whose ever going to know half a dozen doors were open when it wend down.
On the Titanic they closed the doors as soon as the collision occurred. The problem wasn't anything to do with watertight doors. The issue was that the bulkheads didn't extend high enough, and as such, the Titanic could only float with up to 4 compartiments flooded but the iceberg compromised 6 of them.
@@lucah1824 Yup. my point being, when the Titanic came very close to the berg I believe if they closed the doors as a precaution before there was a chance of collision there may have been hope.
@@bluebvur91 Unfortunately there wouldn't have been any hope either way. As soon as more than 4 compartiments were gone, no matter if the doors were closed before as a precaution or not, water would communicate over the tops of the bulkheads at E deck.

Why have people disliked this he’s just trying to help people out
Because people are assholes

Best video about Watertight door, our guardian angels ! good job!
Thanks for the vid my friend almost got crushed by one
my-
I dotn think people appreciate the strength of power actuated watertight doors especially when they slam closed in a emergency they can kill and they have killed and seriously injured,
Brilliant video taught me so much i did not know at all but that looks like compartment 4 not 1!
I've always been really anal about holding onto the handles while going through. Saw one slip with a crewmate few years ago and activate while he was going through. Scared the shit out of me.

Thanks alot sir

@@timaahhh So the doors can still be opened locally even if the master control switch is set to 'Doors Closed'?

I wish they had this on titanic
They did the issue with the titanic was that too many compartments where breached and the water tight compartments did not extend high enough - the water ended up flowing over the top to the next compartmetn as that part of the ship was pulled down by the extra weight of the water.
So can water overspill into the next compartment when it reaches the top of one of the Compartments?

super useful
why they close so slow
Ask, what if the doors are closed from the bridge.can you open and close local then?
Does pirate ship have watertight doors?
No
NOPE!
YARR, THATS WHERE WE KEEP OUR BOOTY, ya lanlubber
How did titanic sink?
The Titanic was designed to float if the first or last 4 compartments were flooded, or if any combination of 2 compartments flood.

timaahhh oh... thanks fore the info :D
timaahhh and i guese u mean the wrong part of the ship got hit

MP cek Sound
Kni
Titanic also have watertight doors
And the TITANIC kept theirs open while at sea… Cost them the entire ship.
Don't say shit like that
That's not true
