We’ve been on bubble watch for a few days now… the main scope of work is fixing a sonar going round and round and round and round and round and round for the whole of our 12h shift, hoping nothing strange will appear on the screen.. if something does appear.. well… we’re f****d.. maybe..
Why bubble watch you say?
The rig is starting a new well, so until the BOP blowout preventer.. there to stop gas to free flow to surface is down on the seabed, if the drill hits a pocket of gas, there’s nothing to stop the bubbles to come right up under us and flip the rig upside down this thing floats.. if you remove water.. well.. oops…
Why not put the BOP first then drill?
I have no idea! :P all I know is that they need to drill to a certain depth, then run big pipes in the hole, then put a base on the sea bed, connect all that together, THEN they can put the BOP...
What can we do if there is a massive pocket of gas heading our way?
Sling shot the rig! for real... :P people are on standby, with a finger by the button, to make all the anchors in front pull us and all the anchors in the back go slack, so if need be the place could jump a bunch of feet forward in a split second... and the bubbles would miss us
so far we haven’t seen anything yay
let's hope it stays this way...

Nice Blogg. Thea reason you can't put the BOP down first is as it weighs 120 tonnes + it needs a stable base to rest on. It first needs the 30 inch casing cemented into place then the 20 inch (which has the wellhead attached) cemented in. This then gives a stable base to lock the BOP onto.

Thanx for the info Ian! nobody could tell me! :) I still think you could design a new type of BOP to avoid the bubble watch part... we'll what it's like in 10 years or so :P
@Bruno c pas toujours aussi mongol.. juste le debut de chaque puit :)
