I was employed by the DHSS when the child benefit scandal occurred, the huge loss of sensitive data

Highly unlikely as that occurred in 2007 and the DHSS was replaced in 1988 by DSS/DoH and then DSS by DWP.https://en.wikipedia.org/wiki/Loss_of_United_Kingd...
I used to work on drilling rigs, as a Subsea Engineer, i have had my own cock ups like removing the PRV (pressure reducing valve) from the wrong (air vessel) to dropping what I thought was the only accumulator locking ring over board (handily after 4 hours of frantic searching I found a spare). Which was lucky as this would have stopped the BOP (Blow Out Preventer) being run, and would have caused a fair bit of expensive downtime.
However all this is chicken feed to a few stories from the world of Subsea.
First was done by a competitor. They had bought a brand new shiny drill rig from Korea, my mate was to be one of the senior Subsea Engineers on there, handily at the time he was at home. The rig had left dock and was carrying out commisioning checks. These checks required the BOP to be positioned in the Moonpool over water. Essentially it is sitting on beams over open water. The BOP is made of two sections, Upper section (LMRP) is the smaller of the two and contains an Annular preventer and the control Pods (along with a few other bits), the lower (BOP stack) is a lot larger and contains the BOP valves etc.
Now the checks called for a test of the emergency disconnect system, in real life this would separate the LMRP from the stack in an emergency, allowing the well to be secured and the rig to leave the area. So they carried out a check of the system, very pleasingly the system operated, however no one had red the huge red letters on the front of the procedure stating the configuration the system had to be in before carrying out the test. Namely the stack should not be hanging off the beams over open water, and this is why now they were looking into the Moonpool to see 200 tons of BOP stack.....not there and heading subsea on it's own. Sea drill cancelled the contract for the rig and handed it back to the shipyard.

The second was closer to home. Blow Out Preventers are the last time of defence between you and the well, and as such are pressure tested to various pressures, depending on what maintenance has been carried out. However not all components in the stack have the same maximum working pressure. A set of rams would have the MWP of the stack in this case 15,000psi, as would the choke and kill valve on the side. The Annulars due to their design have a lower pressure, and the flex joint on top.....well as someone found out....not a very high working pressure at all. Due to a mix up in the type of test cap fitted, the line up on the pressure hose, and a few other things that add up to decent incident. this happened
Which is what happens when you put 7000psi or so in the wrong place... oops. The sheared 1 3/4" studs and nuts rained down all over the rig, was very lucky no one was hurt, and the people involved only needed new pants....and in one case a new job.

I was lost after a few sentences. It's difficult to picture even with decent descriptions
Sorry guys, poor descriptions by me. This link explains what a BOP (blow out preventer) does.
https://www.youtube.com/watch?v=A2Z33hZ-8vo
Essentially the BOP was hanging over a hole in the rig which allows access to the sea as in the picture below
The emergency disconnect system allows the upper section to be disconnected from the lower, in case of emergency.
The test should have been carried out in an area, that would have supported the whole stack (BOP rack back area) and the sequence would have operated, including the connectors disconnecting with out the upper and lower separating ....or drop off over board.
I hope this clears it up, i can see i'm never moving into teaching

44Last year we finally hit the big time, very successful season. Then the boss (stupid fat useless lazy b
d no one ever sees lifting a finger) decided to up and move the whole operation to a new area, didn't do no planning or testing, no due diligence, committed us to moving onto new ground, since then we found nothing and are burning all our cash whilst he and the old man are praying to the Sky fairies for guidance. It's a disaster. He hasn't got a clue what he's doing.

Personally I can't understand why Parker flew his bit of fluff over and then took her up to the claim, let alone let her behind the wheel of a rock truck. At a wedding a while back a fellow guest told me how she walked up the isle with a bunch of flowers and walked back down with half a farm.....

Ex-Ruperts and/or serving officers with no grasp of cost and loss?
Quite the opposite!We do a bit of defence work, mostly small batches of older optical stuff.
We'll get a drawing with some obscure plating requirement involving a witches brew of highly toxic and unstable chemicals, usually there are about three companies left in the UK brave or stupid enough to touch whatever the obscure process is.
As the process is so rare the customer will get hit with a £2-300 minimum charge to plate half a dozen parts.
We can make the same part from a bit of 316 stainless that won't corrode saving a small fortune BUT it would cost tens of thousands of pounds to test and re-certify the part in stainless to ensure there wouldn't be any contamination or other issues with the older parts it would be fitted to.
a very minor one compared to most on here but very funny at the time. during a bank refurb in birmingham a steel beam was being encased in concrete. as the concrete was being poured in the shuttering gave way and we filled a toilet cubicle / room in the starbucks below. how we laughed, they were always complaining about noise or other such nonsense
