Jack-ups don't move, semi-submersibles do move. This is a semi-submersible.

@@Red_Sector_7 oh kool, wasn't aware of more than 1 type

@@jam2190 On shallow drilling, like the Gulf of Mexico, or off Nova Scotia coast you will see jack-ups mostly. Semi-submersibles are in deep water like north Atlantic.

@@Red_Sector_7 neat

@@Red_Sector_7 deep waters means how deep the sea is ???

I dunno ...I’m guessing you get used to it...and that rocking must be quite soothing and help with sleep after a long hard day on this thing

No. They’re designed to withstand it. And it’s just floating

Can you explain sea's depth under the rig?

Polluting the Ocean Chip by Chip !! Fucking Brilliant !!! Lolololhahaha

Would you feel better, if the CEO was flown out to the platform? That is the only reason why he/she should be there, that I can think of.

@@Salty_old_Viking "whoosh".

@@jimmiller5600 There is no whoosh over this and there is no risk involved in this situation. You just don't like CEO's (and big waves, apparently).

@@Salty_old_Viking Whoosh 2.0 -- Try Ocean Ranger. Or for non-weather related Piper Alpha. Or BP's Horizon rig. Or.........

@@jimmiller5600 Try Google r/whoosh to stop embarrass yourself

It is an accommodation unit, the drilling is done on another platform!

the pretty much use massive suction cups to attach to the sea floor. that's why they rock like boats but stay in the same place.

@@jdymes101 seriously ? how big are the suction cups? are they made from rubber?

@@psystealth Suction anchors are hollow steel cylinders open at the base and covered on top, like an upside down glass. They are lowered into the seabed and sink under their own weight only so far, then a valve at the top is opened to let the entrapped air escape, allowing them to sink further into the seabed due to the weight of the water on top of it.

@@jdymes101 They also employ azimuthal pods for dynamic positioning (DP) together with a mooring line tension monitoring system to limit drift and reduce the chance of breaking free.

Oh yeah That looks about right. Its very hard to capture wave height on video, and the vessel is huge and rises and falls with the seas so unlike videos of stationary platforma mounted on the seafloor, the waves cannot be measured by how much the waterline moves up and down on the hull. But even doing that the water is moving considerably. Ive worked on a very similar vessel where it was ballasted up to where the top of the pontoons was 4ft above the waterline and can attest to how massive these ships are...Really marvels of engineering. They can have both fully capable sat diving along with ROVs on a platform that includes multiple heavy lift cranes, all with nearly the stability of a semi submersible platform if an anchor spread is used...but mostly they seem to use DP to electronically hold position allowing them to move with the work with pipelines or love locations relatively easy and on moments notice as these are fully mobile ships, not platforms or barges...they utilize support vessels for resupply at sea when working but is a fullly self controlled, self propelled ship

I'd say you're looking at 40-50ft waves at the end of the video. In calm conditions the height from deck to sea level is probably touching 100ft and the waves are certainly half the height of the legs.

Used to be well paid, not anymore mate!
