BOP closed accidentally


It happened in one of the rigs of an Algerian drilling contractor, while pulling out of the hole suddenly the weight increased and pipe was cut due to the high overpull applied. The investigation mentioned that the pipe rams was closed during the POOH, and this was the main cause getting the pipe cut.

The spread words on the rig and in the office are saying that the BOP was closed accidentally by itself.

I am a well control instructor, and couldn't believe it.

Please if someone could and answer to that: would the BOP close accidentally by itself? (Also they are saying that the control unit pumps run every one minute....!!!!!?)
