Jack-up vessels are widely used in the Offshore Wind industry, installing (hammering) monopile foundations and installing the towers, turbines and blades.
However, they are moving towards floating installation vessels since turbines are being installed in deeper water.
On each location where these vessels want to jack-up, they have to do site specific assessments in advance to ensure stability.
The jack-up operation it self is 'relatively' quick.

Well, the technical name is: MODU, or mobile drilling unit. They are all over here in the Gulf of Mexico.

Chris these type of vessels / platforms are called ‘Jack ups’
I believe they were first invented for working on drilling oil wells in the Gulf of Mexico.
They are relatively common in offshore oil fields.
I worked on one in the Grand Banks in the 70’s
They are very stable when the legs are “ jacked down” and resting on the bottom; they elevate the working decks well above the waters surface.
They Jack the legs back up to move the vessel from place to place.
They are not very stable ‘ nautically’ when the legs are up and floating on their hull because they become ‘top heavy’ .
