This is purely for learning purposes. You can see what happen in the footage below. Three man were inspecting the top drive system on the rig floor. All the sudden the drilling link was accidentally released and it hit these guys.
What can we learn from this video?
Energy isolation – Energy (electric and hydraulic) is not properly isolated so when the man accidentally operate the top drive link tilt, the link is moved without any warning.
Trapped energy – It might have trapped hydraulic pressure in the system. People may not recognize this point.
Line of fire – The team is not aware of line of fire and what if if the link is released.
Incorrect procedure – Based on the footage, the guy who is standing in the back moves back behind may some mechanism resulted in the link moving and crushing another man.
How can we prevent this from happening it again?

This is one of excellent training video demonstrating the drilling process from start at surface casing to completing of the well in less than 7 minutes. This would be a good tool to teach people about drilling in our oil and gas industry. We also provide video transcription in order to help learners understand the content easily.

The well is in an underbalanced condition while pulling out of hole. You can see in the video below that the fluid is flowing up from the drill pipe side. It is such very important to understand the condition of the well and have the plan to deal with it.
These are some thought about this situation from our member in the Facebook fanpage.
Hossam Hamza – Looks like it was failed balanced cement plug job, I see long cement chiksan line on rig floor and circulating head connected with low TQ valve above 1 joint DP in mouse hole, the back flow due to over displacement. Is my guess right???? Continue reading →
Shell has started production from the Stones development in the Gulf of Mexico, the world’s deepest offshore oil and gas project.
When fully ramped up at the end of 2017, the development is expected to produce approximately 50,000 barrels of oil equivalent per day (boepd), the company informed in a statement.
“Stones is the latest example of our leadership, capability and knowledge, which are key to profitably developing our global deep water resources. Our growing expertise in using such technologies in innovative ways will help us unlock more deep water resources around the world,” Royal Dutch Shell Upstream Director, Andy Brown, said.
The project, fully owned and operated by the supermajor, is Shell’s second producing field from the lower tertiary geologic frontier in the Gulf of Mexico.
According to the company, it features a more cost-effective well design, requiring less material and lower installation costs, which is expected to offer a US$1 billion (£749.38 million) reduction in well costs.
