I made a multiblock structure as written in the wiki but it doesn't work. I don't even understand how to supply power to it.
Please tell me if I'm doing something wrong or is this a bug?

If you build it wrong or in the wrong place the structure doesn't form.
If the structure doesn't form cables do not connect to it.
If it forms any block part of the structure (even the wood) accepts power.

Please send an image of how/where you built it.

As I understand it, there is enough water in creative mode, but in my survival there is very little?
(The designs are the same, but in creative mode it works)

You've built it right as I can tell from the fact that the cable is connecting.
Just make sure you have enough power provided.

Also EU Reader and TOP/Jade might give you some more info on the progress.

I just rebuilt this structure in the ocean biome and it worked, sorry for bothering you, I should have checked it before opening an issue. Thank you for your help!

Also make sure the chain length is between 5-10 blocks
