So.... what is it you do?

Thought some might be interested in what everybody does for a living so to kick it off I thought I would share what I was up to during the middle of 2011. Haven't been about much for the last 6 or 7 months because after 20 something years working in the North Sea I decided it was time for a change and took a job working on a new build project of a 6 generation dual activity drill ship.
What makes these significantly different from the usual drilling rigs most people have seen pictures of is that they have 2 drill floors side by side. The reasons for this a numerous and complicated but in a nutshell it allows one well to work continuously without stopping while the other drill floor (Aux) prepares the next assemblies for the main well.
They say a picture speaks a thousand words ..........
Ocean Rig Poseidon on sea trials (no jokes about the name, heard them all
)
Looking down from the crown level, top of the derrick. You can see both well centers (red round things) One of the top drives (big black & decker drill) hanging in the derrick. The tall yellow thing holding a stand pipe is one of the 2 robotic racking arms called Hydrarackers. These can work in either manual mode, controlled from the cyber chair or in auto mode where the operator only confirms each step and the arm does the rest. Used for moving pipe in stands (3 or 4 joints screwed together about 120ft long) around the derrick.
Another view this time looking up from the monkey board level (about half way up the derrick)
One of 2 finger boards used to store the stands of pipe once they are made up.
Another view this time from drill floor level, top drive on the left, both hydrarackers in the middle and you can see the lower and upper fingerboards on the right.
The lower yellow thing is main wells hydratong which is a big spinning wrench and torque wrench in one. Will make pipe up to 115000lbs/ft. The bit sticking out from the derrick above it is the EBT (elevated back up tong). Allows pipe to be connected together when drilling while keeping the bit off the bottom of the hole.
Some work going on aligning all the gear and tuning the ACS (anti collision system, bit like traction control for a drill floor )
2 drawworks, basically big winches that raise and lower the top drive and anything that is connected to them. Max lift capacity is 907mt or about 2,000,000lbs.
5 of 2200hp mud pumps rated at 7500psi. Each one can pump at 600 gallons per minute depending on the liner size and pressure.

One of the drillers hard at work!!
Little sequence of pics of the BOP (blow out preventer) being delivered by an 8000ton dock yard barge crane (more on these later). The BOP is in 2 parts, the LMRP (lower marine riser package) is the bit that is already in place, and the BOP itself which has all the bits and bobs to allow us to shut off the well from the rig if it all goes wrong. All up weight when both bits are stacked is about 360tons.
Power comes from these babies. 2 in the picture but we have 6 in total giving 8,000 KW each.
There you have it, what I get up to when I am not hooning about in my Evora.
Your turn
