Question 3238 Deck General
70% to passThe shear rams of a MODU blowout preventer stack are used in emergency well control to _______________.
A
close and seal around casing
B
close and seal around the drill pipe
C
close and seal around drill collars
D
cut off pipe inside the preventer stack
AI Explanation
The correct answer is D) cut off pipe inside the preventer stack. The shear rams on a MODU (Mobile Offshore Drilling Unit) blowout preventer stack are designed to close and cut through the drill pipe in an emergency well control situation. This allows the well to be sealed off and the flow of oil or gas to be stopped, even if the drill pipe is inside the preventer stack. The other options, while related to blowout preventer function, do not accurately describe the purpose of the shear rams.
