Drill Collar laid across the rig floor
Drill shack was totally damaged.
I hope the driller did not get hurt.
The drill collar was dropped inside the driller shack.
This was another view which was pretty scary.
The broken glass was everywhere.
The panel and joy stick were damaged.
The drill collar was dropped into the shack.
Everything in the room was ruin.
Look at the derrick. Two drill collars laid across the derrick.
The drill collar, bit, wear bushing, etc on the rig floor.
Few more pictures are below.
Dear Shyne
At l984 I was working for Petrobras on a jack up rig and I had a incident not exactly like this one. All drill string were on setback and from top the second 10″ drill collar broke the pin, the two upper drill collars came down making a hole on drillng floor stopping on a bean below and the last drill collar remained leaned at side of derrick.
Many regards.

Possible over torque or lack of torque collar connections, combined with downhole temps, and flexing while racking back in derrick. I’ve seen them almost back out due to the motion of the derrick.
Hmm? was this on the Ocean Rover?
I have been told it was on the Ocean Baroness – it just looks the same as the Rover
This one actually was Pipe Racker operator mistake.
(Was not like actual system where this error could only be caused if you use Overide function)
On this finger board system you have a push button to open the finger on selected row .
As the first stand of BHA you can see on the pipe racker was grab by the operator to start RIH, he push the “finger open” button, as the stand was leaning against the finger it do not open.
So operator push “finger open” button 3 more time (giving command to open 3 more finger….)
When Driller tell him to pick up a little bit the first stand in order to “help” the first finger to open, he do so.
After retacting racking arm PRS start to travel to well center. As finger open command was given 3 more time on this row, the 3 following fingers open resulting on the next heave to have 3 DC Stand crack loose.
That’s why you should always have a spotter to look at the fingerboard and visually confirm that only one finger is open, and remember if in doubt don’t by SHY, stop have a look or ask question to sort it out.
I will not give the rig, neither company name cos this is not about pointing finger , is about learning and raising your awarness on safety behaviour .
