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?
Another RUclips 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
Thank you for making this video but it wasn't as easy when I stripped and painting,hand painting that is so it's great to see progress and cost saving working very well together.👍⭐
I work doing ship repair in Belfast ,, northern Ireland ,, for the Harland and wolf ship yard ,, good work but hard ,, heavy ,,I do pipe work fabrication ,, various other work ☘️☘️☘️☘️
I have been both sides of this while I was in the Navy.....onboard ship and on 2 floating drydocks, 1 did submarines and 1 did surface ships, very labor intensive for the Engineers
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.
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.
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
@@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.
I spend a lot of time perusing RUclips, 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?
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.

I know how it is done on sailboats. When she is lifted to be put in the water, I stand with a can of paint to quickly paint the parts she was sitting in while on shore :)
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.
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.
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 do t know anyone that could hold the gun at 40k (2.8k bar)

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.
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.

Yeah you caught me 😂
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!
Imagine displacement and wonder why you got to do the shitty work.
hey stave can I have your mail please
“You can’t paint the rudder while it’s under water” Nice to know I learned something!
the size of the floating drydock... mind blowing.
'You can't paint the rudders while they're underwater.'

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

Outstanding video.
🌎👍❤.
How do they clean and paint the areas where there are support blocks?
Outstanding video 👍👏
On the keel supports, how are they moved in order to paint the hull ?
Each block is lowered and moved individually to paint the area, then placed back to the original position.
I ALWAYS learn something with these videos! Keep up the good work
Enjoyed your video so I gave it a Thumbs Up
Awesome video thank you

What dock do you use for the floating dock to be docked?
I've worked with dry docks it is very hard blasting and maintenance inside the tank but you are watching out side maintenance here
Wouahhh...Very very impressive !!! 😯👍
I wonder if a huge ship ever slipped off of the supports? that would be one hell of a loud crash !
What happens to the bits that are sitting on the blocks? You can’t paint or clean those parts
I know how it is done on sailboats. When she is lifted to be put in the water, I stand with a can of paint to quickly paint the parts she was sitting in while on shore :)

How do they paint the bit of the hull that sits on the blocks?
This is so cool.
It's my dream but until I didn't get any platform for this job
Nice
Did they have dry docks for floating dry dock ?
Marvelous engineering
Is there a free-floating dry dock for free-floating docks when they need maintenance? They look to be too big for a land-based dry dock.
Actually there is a complete ship that can sink under a vessel… and lift it .. it looks like a big Flatbed boat
How much cost of this beast
How do they work on the areas covered by the hull supports? 😳
Ah!! The door connects to a water body! That's where I went wrong with my one.

I wanna work in ship as a crew mechanical

They need to be smaller than the Ocean. ;)

Why don't you just skip the "bars" and give us the pressure?

She does not understand what she is narrating, things like saying ships have "four" engineers, and talks about the dry dock doors.

Good day. The re are dry and floating docks. There is a sistem called sincro lift.
Dry dock...? Compare how heavy steel ship can float. What does it float...?
So how do they clean & paint the parts of the ship that is sitting on the blocks?
I was wondering the same thing. Anybody??

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.
