Since we have some sub sea and more drilling related folks joining, I’ll ask this again: If the BOP on the rig floor becomes compromised - blown apart, wires shorted to lights and function buttons, does it compromise the other two? Also, where was the sub sea shop - BOP fluid pumps - in relation to the moon pool? I would think with most designs and the piping/wires that come out of there, it was located within one bulkhead of the moonpool.

No; compromising one panel would not compromise other panels. These systems utilize computer/PLC based systems that are coded communicaitons. They can’t simple short out and cause a fault like you might have in a traditional electrical circuit. These systems are deisgned to to API standards and those standards dictate very clearly that a failure or fault in one remote panel cannot cause a failure or fault in another panel. Some systems on some of the old rigs could have this problem but not anything built in probably the past twenty years for deepwater. Not sure of the location of the main hydraulic unit aboard.
