Offshore Piles Construction 

Is the casing/ caisson permanent? I cannot see how it can be removed after concreting or the pile will collapse into the water while concrete is still wet?

👍Great video. Very easy to understand👌.

Seems like a rhyme 😄😄

Nice info

nice the only thing you might missed is how to survey the pile location, but really nice good luck of producing such videos

Just poring concrete? What about salt water present inside the casing?
