Didn't know there were rigs in the Forth? We've permanently got loads in the Cromarty Firth.

Trying not to sound dumb here, but I didn't realise oil rigs were mobile! Or are you talking about smaller floating ones or what?

Forum Moderator Joined: 02 Mar 2004 Posts: 19978

all rigs are mobile, JB asked the same thing!

All that attaches a rig to the sea bed is the drill.

they float on the water

But what about the really huge ones like the one Ben Affleck gets chased around by Bruce Willis at the start of Armageddon? Ones like that aren't mobile are they? Shocked

they all float! you have an ocean, it goes up and down, a rig stuck to the sea floo will not go up and down with the waves, end result wave over the rig.

The legs go down about 50 feet in the big rigs cases. They are attached to the sea floor by the drill.

The drills are massive as well, very impressive. The drill passes down inside a tube when a wells opened theres initial surge thats when oil come sup the tube and spurts out, after that it needs pumped up.

All very impressive stuff.

me old man used to make the drills for the rigs and fit them. Now he just gets choppered out to push the button.

Yeah, but in the pictures, the rig is always about 50m above sea on legs, which i thought was to allow for waves.

it shows the different types. the platform is the only 'fixed' rig which tend to operate in shallow waters.

The other mobiles ones either flot or drop legs down which rest on the sea bed.

They dont all float

All the rigs iv been on are "fixed rigs" which means that they have 4 legs and these 4 legs go all the way to the bottom of the sea and are secured to the sea floor, these rigs never move and never will unless they are demolished, the rig im on at the moment has been here since 1975,

The floating rigs are "drilling rigs", they will either be towed or move by themselves, not all fixed rigs have Derrycks (the drill bit) so a drilling rig will go to the fixed rigs location and do the drilling for it, once it has done its drilling job it will them attach the oil pipes to the fixed rig and the fixed rig will do the rest ie sucking it out the ground, then the drilling rig will move on to its next job,

A fixed rig may not be actually sucking the oil from directly underneath it, the point where it is sucking the oil from may be a fair bit away, but it will have oil lines going to the fixed platform, the there will be more oil lines going from that fixed platform to another smaller rig location a few miles away where it then gets routed to the refineries,

The waves dont come over the top of the fixed rigs as the lower platform is about 80-90 feet above the water, it does'nt look it in picture's, but when you have to abseil over the side underneath the rig it looks it then Shocked

What you can feel though is a very small swaying though.
