It's 2am time to learn about drydocks!

[@davetherave5]

Lol. I just looked over and it's literally 1:55am

Iv worked for 2 drydocks,worked on a dredge for yrs,worked on jack-up oil rigs all over the globe & it still amazes me how so much iron can float!

the size of the floating drydock... mind blowing.

It's a quirk but in the context of pressure measurement "bar" is always singular.

[@yuripavlov8508]

Many thanks for this video. Brief and and quite informative!

[@venkateshpatel60]

Great video! Since the solid cube blocks directly contact with ship. How is the contact area cleaned and repainted? Do they need to clean and paint, then flood the dock, use tug boat to move ship a little, then pump water from dock and then clean and paint the previous contact areas?

[@bobhailey1290]

Another KZbin video said they position the blocks differently next time they paint it and they just don’t paint that area of the ship until next time they dock

[@venkateshpatel60]

[@jameslowmanjr6141]

Thanks. You hear about it maybe once or twice in your life when you’re not really around water. You know I live in Pennsylvania so when you’re up at Erie lake. Maybe once man look at that big ship wonder how they do repairs on that. Well thank you I got to see how it’s done. One problem those mobile dry docks. What happens when they break down with the ship in dry dock. Do they have a dry dock that can handle them and does it go to them.

[@bernieshort6311]

I have been in many drydocks both working and observing. I learnt my apprenticeship in a Royal Navy dockyard and continued to use drydocks as a merchant navy engineer when the ships I served on were drydocked. One thing has always puzzled me and that is: When a vessel is placed on the keel blocks, these blocks are place so as the entire weight of the ship can be taken by them. These blocks are placed according to the structure of the vessels hull so will be placed in similar positions every time a vessel is docked. This means that throughout the entire life of the vessel these areas of the hull are never blasted or painted, these being the areas where the vessel sits on the blocks. I have always wondered, but never asked the question. Why don’t they re-float the vessel once its painted, move it so as the blocks are now sat on painted areas of the hull and then blast and paint these final areas. But this is never done therefor as previously mentioned, there is a massive underwater area of a ship that never gets treated. One would not accept any other vehicle that was only partially treated underneath, so why are ship accepted like this? I guess it all comes down to cost, but I don’t really know and wished I had asked the question when I was in the position to get a proper reply.

[@kennethgrindrod6438]

I have worked a naval dockyard in the U K as a painter we’re the shipwrights used to move blocks at certain times so we could blast and paint the areas before putting them back and the same went with the long support poles

[@bernieshort6311]

@@kennethgrindrod6438 Thank you for this reply, it has answered my question. I have never seen this done but to be honest, as an engineer, I was always busy when in dock. Thanks, you for clearing this point up for me.

[@DownhillAllTheWay]

I spend a lot of time perusing KZbin, and not very long ago, I came across an article about paint that said it could be applied, and would dry/harden "even under water". It may have been an epoxy paint, but I can't remember. It didn't say if this is ever used for maritime purposes, but for the relatively small areas along the keel blocks, mechanical scraping (I'm sure there are automatic gadgets that would do it), and underwater applicable paints would seem a solution of sorts. Have you ever come across that, Bernie?

[@charlesgantz5865]

I had heard that when a ship is drydocked, the locations of the blocks relative to the ship are set very precisely using surveying equipment. Then the next time the ship is drydocked, the blocks are positioned so the parts that weren't painted last time now get painted.

[@davidbross6942]

How do they paint the parts of the hull resting on the support blocks?

[@nmccw3245]

Blocks are redundant enough to remove a few at a time, paint the exposed hull, then replace the blocks before repeating the process. You can also use different blocking plans during each drydock period so the same locations are not covered every time.

[@affleck80]

On the keel supports, how are they moved in order to paint the hull ?

[@brazillo19]

Each block is lowered and moved individually to paint the area, then placed back to the original position.

[@erbenton07]

So how do they clean & paint the parts of the ship that is sitting on the blocks?

[@overdoneone]

I was wondering the same thing. Anybody??

[@myblueshades]

If you notice at 1:42 there's wooden chocks loosely pinned to the main blocks. So it's a fair assumption that they are removed & repositioned in rotation until they all have new paint.

[@overdoneone]

I wonder if there's any limitation to how big a ship can be? They're growing so much that I wouldn't be surprised if we see a ship nearing a kilometer in length in the next 20 years.

[@dzello]

Ships are generally built to fit the canals. The size of the canals is a soft limitation of ship building: it's not super worth it to build a massive ship that can't go through the canals because it ends up very limited.

[@theobserver9131]

They need to be smaller than the Ocean. ;)

[@rburn6677]

Ships can't be too long because when they go through the swells and the stern is on one swell and the bow is on another the midships need to still rest in the water between the swells for support. A real long ship risks the midships section being out of the water and losing support of the ocean and frequently will break the ships back and snap it in two.

As someone with blasting experience that’s not the appropriate pressure range and the also you and abrasive. The amount of pressure you had said was used would be unsustainable for any person to hold. 33gpm at 20kpsi is getting close to the limit.

I had the privileged of working ( since 1977/1988) in the biggest dry dock in the world ( at the time,and i dont know if there is a bigger one today), located on the Lisnave shipyard,in Lisbon Portugal,and at the time the largest shipyard on the world. The dry dock that iam talking abaut ,dock n13, has 520 Meters of lenght and could support ships until 1 million tons. It still exist being part of National Heritage. After the shipyard close down,almost 1500 men,from Engineers to welders and scaffolding experts,etc were invited by the UAE to Start the construction of theirs shipyards,all with Portuguese expertise. And the rest its history. I miss working under those 350,400 meter supertankers...was a world apart.
