Flamu for the saltiness, Jingles for the stories, drachinifel for the history and ichase for the technical knowledge. Im loving it please keep it coming
You forgot Flambass for the "WHAAAAT?? *WHAAAAATTTT???* "
@@dany1441 he is to balanced ^^
Of course :)
Aye Odd Magnusson, iChase is quite the Chief Engineer.
oh yeah, it's all coming together
Don't forget that water being pumped overboard could also be sea water that was used to cool the engines, but mostly its bilge water.
Engine coolant is recirculated, but you're right, they do pump water out of the exhaust to cool the exhaust.
@Keith Cripe
I don't think that cooling water is usually mixed with the bilge system. Correct me if I am wrong, cause it's been like a decade I last saw a naval machine plant schematic, but I am of the belief cooling water is usually pumped out of the sea-chest and pumped out through a connection at the sea-chest itself. And probably depending on the plant (cause I am more accustom to diesel-generator drive), the seawater section can be split from the actual cooling water by means of heat-exchangers. I've seen this used regularly on diesel-electric plants because those diesels tend to be designed a lot closer to industrial diesel-generators, with multiple units active depending on the load.
Yeah fresh water on engines, to heat exchangers cooled by seawater as you don't want the salt degrading your engines. Bilge is its own isolated system. You also use SW to clean exhaust gases for environmental reasons, these have their own controlled overboards aswell.
I agree. It's a pretty touch. Nice discussion of bilge pumps! I have some additional information that I hope you will enjoy ...
Steel vessels in good condition leak very little. Except for weeping at the propeller shaft packing glands, most of the water that ends up in the bilges of a steel vessel (excluding rust holes or battle damage) is condensation collecting on the inside of steel hull plates below the waterline cooled by the surrounding ocean.
The major reason for water discharge is cooling circuits for various on board machinery. The most important of these cooling circuits are 1) the steam condensers and 2) fresh water distillation. Any such discharge will be above the waterline for safety reasons - if damaged a discharge pipe above the waterline won't endanger the ship the way a sub-surface pipe would.
Steam driven ships recycle the boiler water by venting the steam into condensers, which were cooled with sea water. This condenser cooling water is always pumped overboard above the waterline. This is why ships don't continually vent steam and 'chuff' like railway locomotives (it's also why forced draft is necessary for high pressure marine boilers, while the blast pipe on a steam locomotive vents the waste steam up the funnel, causing a suction through the firebox and performing the same function). The reason for this arrangement is that boiler water had to be exceptionally pure - any mineral content would immediately coat the water passages in the boiler and dramatically cut the boiler's efficiency.
And, so, any water for the boilers had to be distilled on board, which is why ships carry huge distillation plants. Those fresh water distillation plants vent their wastewater overboard, and are operated pretty much continuously when the ship is operational. Of course, drinking and cooking water is also generated by these same plants. Toilet flushing and sometimes bathing would be accomplished using salt water.
To a lesser degree, refrigeration plants and gray water discharge is also present. I do not know how naval vessels of the era handled black water discharge. I do know that, outside of harbor, such was discharged overboard - but I don't know if they made an exception and vented that below the waterline due to aesthetic considerations.
that water leaking is the tears of us players that see the shit going on in the game
That is ship sweat. When a ship drives long distances, it really strains the system, and the ship breaks quite a sweat. And that is coming out of those pores.
Back in the sailing ship era, this was not the case. Ships used wind effortless, instead of their own power, hence they sweated much less. This is why the sea levels are constantly rising around the world: More and more ships under their own power sweating into the oceans, slowly filling them up. That is also the reason why sea water is salty.
It also to dump water from Ballast tank though.
Aside from maintaining Stability and keep the Weight from being Topheavy (keep it at waterline level).
ballast tank also used when Ships took hit, and when the ship is listing - Ballast tank can be used as counterFlood to keep Warships from Capsizing
In many WW2 Carrier design, they also put Ballast tank near Aviation fuel / magazine , so when Catasthropic Hit happen. the fuel will be Diluted with water and to minimize the risk of stray Spark hopefuly preventing "Juliet Charlie" achivement.
To ALL: Water is not only pumped from the bildges... Seawater cooling systems on surface ships and submarines provide cooling water for heat exchangers, removing heat from the propulsion plant and mechanical auxiliary systems. ... The seawater is pumped through heat exchangers where it absorbs heat and is then discharged overboard at a higher temperature.
They are not holes in the side, they are overboard discharges. Also MARPOL does not allow overboard discharge direct from bilges. They go into a black & grey holding tank for filtering and can only be opened in specific areas and under specific conditions. The majority of the free runnings you see on ships are from Sea Water cooling. These can be directly discharge as they are clean water (recently sucked up) after passing through a heat exchanger.
Yeah, I explained that you can't just pump it overboard due to regulations. Needs to be treated
Yeah it was a gr8 vid and my comment was not meant to be critical of the video just additional context as a Marine Engineer. You did well. You could also do a video on ballad ring as part of damage control is stability. Every ship also has a jettison plan to ditch heavy stuff over the side to control listing in the worst case scenarios. Thanks m8 hope your well
Ah, I thought I didn't do a good job making the point very clear in the video, so said it again in a comment. Didn't take offence, the tone just doesn't come across well in text form. I actually forgot to mention that the systems thing is very much the domain of a marine engineer XD thx for replying
Damn auto correct should be ballast’ing. No the opposite is true from a non mariner or engineer more videos like this should be available as it adds to the immersion in game. You did gr8
In a steam powered naval vessel, there are some steam leaks. So, that water will eventually condense, ending up in the bilge. NO ONE EVER wants to get stuck with cleaning a bilge, for some reason...
One or two of those streams could come from the auxiliary generators, they're usually water cooled on larger ships and would be running continuously in port with the main engines shut down.
Yep.. either raw water cooled or they’ll use keel coolers which is a closed system using freshwater and coolant. The boat I run has keel cooled generator sets and raw water cooled main engines… but I’ve been on boats that use keel coolers for the mains as well.
1:40 ah yes "Simple"
seriously though, I really love this sort of content. Very cool stuff to learn about. Also, your 3D model is awesome
The primary source of bilge water on warships of the WoWS era would be leaking seals. Water pumps used for cooling (heat exchangers, etc.) had a packing gland around the shaft leading from the pump to the motor consisting of fiber rings held somewhat tightly by a packing gland. This system depended on a certain amount of water leaking through the gland to cool these materials - otherwise the friction from the turning shaft would burn them. It should be a steady drip, drip, drip but if they are not regularly checked and maintained there can be more of a flow. And these ships have a lot of water pumps.
The seals around the propeller shafts also leak a bit for the same purpose.
There would be other sources as well. I was assigned to a frigate-sized U.S. Coast Guard "High Endurance Cutter" that had a very efficient "evap." (Distillation plant to convert salt water to fresh.) During the night watches we would often dump the evap to the engine room bilges after topping off the fresh water tanks because it was a pain in the butt to shut it down, start it back up, and get it tuned.
It would not surprise me if modern ships have more efficient (and less maintenance-intensive) seals on their water pumps.
I remember being in a tourist speedboat that used water to cool the engine. The pilot forgot to turn on the pump or he forgot a discharge valve, I don't remember because I was a kid. Either way, the boat flooded and sank in a canal. We made it off to the bank but it was a harrowing experience.
"My first 3D ship structure" looks a lot like an airplane fuselage structure. Z stringers galore stiffening the skin, with frames. Aviation uses terminology borrowed from naval architecture, waterline, buttock line and station - Hmmm...I suspect aviation got the idea from somewhere......... A rule of thumb is: Not more than 10:1 length to thickness on those unsupported flanges - better yet, add a lip on the end to keep the end from buckling.
Air might not be as dense as water, but aerodynamics isn't much different from hydrodynamics and the idea that a vehicle has to be light enough to not sink/fall out of the sky, robust enough to not break apart from any of the stress and also energy efficient while gliding through the gas/fluid is kind of shared.
Just to add to that diagram, those a shaped valves are check valves which ensures the water flows only in one direction.
That's cool! I hadn't noticed the water flowing out. What a fine detail!
was wondering that but did not know where to ask, thanks iChase
Loving all these naval knowledge and tidbits videos Chase! Keep em coming!
Thanks, will do :)
Great to see you back, my man! Good vid.
Also on a ship you need lots of water that is pumped in directly from the sea to cool the engines or guns and toilets, basically everything that does not require fresh water.
This water also has to leave the ship of course.
yup and as someone thats had to go along the what was the 3D model at the end and clean that along that space (for rust removal) they are pointed down and are a complete pain the ass to get around
I just recently unlocked the Montana (My 3rd T 10! =D) and noticed this coming out of the side the first time I took it out. At first I thought it was something maybe particular to the ship when I first noticed the bilge pumps. It's a neat detail.
thumbs up cause your alive.
Great video, thanks for taking the time to make it.
1. Regarding the longitudinals you have on the sides of the ship, as an retiered captain with close to 40 years at sea i have never been on a ship with that system, all the ships i have been on were constructed with normal vertical framing and "stringer decks" with manhole openings for the water to escape through.
2. I have never used water in firedrills when the drile have been carried out in the internal compartments of the ships, this due to that as you said in the video is a loss of stability , but also because the water that is used is pumped directly from the sea so it is saltwater, and saltwater is one thing we do not want inside of a vessel in areas not designed for it due to corrosion.
Longitudinal framing systems are used for long ships, primarily those in excess of 120m. Others will use transverse framing systems. Some ships today will also use a combination of the two.
True, you wouldn't really use mass amounts of water during a drill. I guess I was using that mostly as an easy to understand example as most people who watch will not be mariners
@@ichasegaming my last ship was a 240 meters carcarrier and she didnt have logitudenals other than in the flat bottom on the sides it was vertical framing with a stringerdeck about every12 feet
Yeah, combination framing is also a thing :) longitudinals on the top, bottom, transverse framing on the sides.
marineinsight.com/wp-content/uploads/2015/03/P1030093.jpg also this image of a bulk carrier shows the longitudinal framing
Hope you are well and kicking iChase! And as always take care!
3:55 I expected you to mention another great part of it. As we also can see when the pumps in work the engine is also goes, which make those pumps at work. Like 0:31
This will also happen when your ship is flooding from a torpedo hit and you press the repair.
Problem solved
Thats the Bilge system? Good to know. Was wondering where that water was coming from.
I love these, thanks so much!
P.s. That camo! 😍
It's even worse when you're out to sea on deployment and the bilge pipe burst and you're stuck mopping up the water for a few hours :)
Use a bucket lad :)
My destroyers' bilges are full of tears from 2 CV per team matches.
hiya iChase it's my favourite Canadian CC, back from outer space! And he's explaining a Piping Matrix/Manifold! if I could see him streaming, life would be perfect! Both the gate valves look like they use the same symbol?
nice job man congratz
Speaking of mechanical ship stuff, What are the round metal scaffolding looking things sticking out of the hull at the back of the ship (thats the best way I can describe it)? They can be seen on most of the US and French DDs
Propeller Guards
Prop guards :)
oh, that makes sense. thanks
As always, little details that matter
Kudos to WG Art Dept. & you
Pls do more videos. Really informative.
Where does the oily crap in the oily bilge tank go? Do you get rid of it whenever you go into port? Is the amount of liquid collected from it enough to destabilize the ship? Are there circumstances wherein you can dump the stuff at sea without facing fines? (Like idk, certain emergencies?)
Oily Bilge Tank, they store it until they get to shore facility to unload it. Cannot dump at sea
Ahh free surface effect and excess water my ship is very stable just with a 5 degree list to stbd xD....Engineers swear its just the wind thoo...there have definitely been enginners who for got to open the outboard discharge valves first... That'll fill a bilge quick too xD
as long as it comes ou of the ship and not goes unside
Art department flex.
cool camo!!!
what camo is that?
Could you do one about the weird openings om the side of turrets? It looks like a muscle car supercharger intake but I have no clue what they do, maybe air intake for the turret?
The local range finders?
@@ichasegaming I have no idea, I know the big "radarlike" on the top are range finder for the main battery, and the small ones on the sides of the ship near to the secondary battery is the range finder for those. But the intakes on the turrets I have no idea what they are called sorry.
Those are not intakes, those are range finders that allow for local control in the event the main fire control is knocked out.
@@ichasegaming thanks man
Sooo... when you building your personal yacht? :D Full construction process videos will be very nice ^_^
Definitely thinking about it lol, might need a more education and experience
@@ichasegaming and funding? Or is Patreon doing that well :P
AYYYYYY HE'S BACKKKKKKKKK!
Good explanation. I like content like this
Glad you liked it!
lol I thought it ứa thư cooling system
I like that camo, I do. I realllly doo
That is why WG's art department is always MVP. Sadly their hard work is always ruined by either the balancing department or the marketing department...
#justiceforWGartdepartment
What balancing department?
U live? U LIVE?! Kappa
Filled bilge tanks r also a great place to hide contraband 😜
water is used to cooldown hot mashines and engines ect...,and this is also working when a ship is stationary.
what dumb child question is that:
My ship is leaking.
is your car´s fan stopping on hot summer when you turn off your car engine?
Mostly NOT!
Because the car´s fan at the front is still running couple minutes to remove hot air out of the engine room and also to cool down the watersystem from the engine.
What about the quarterdeck of HMS Hood, the Royal Navy's largest submarine?
Second
third
In have been waiting for a video for a long time :)
:D sorry for not uploading as frequently, school is doing school things to me >_
@@ichasegaming lol np bro, School is doing things to me too
Battleships are like women.
They both leak when they are fucked
first?
FIIIRSSST :D
Don’t forget about seawater leaking in through the shaft packings as well. That is where a majority of seawater enters the bilge from.
Yup, I didn't list all the places where water comes from. Thought it woulda been kinda boring to list everything haha. But you're absolutely right.
@@ichasegaming keep up the good work. I wish you had some insights into the world of World of Warships Blitz… I’m anxious for the Kidd to make its triumphant appearance on my iPad!
