just curious man..what did you chose (between fixing the pump on the rig or investigate it).. the way I see it, there are no right or wrong answer.. just the reasoning part..why one would choose to do this and not that.. is it?

i thought so too... Some more i think that they would have backups/standby pumps on the rig..
i knew for a fact that this is the case of operations in the power plant (i did industrial training there before).. actually you don't even have to fix the pump first or anything...
every pumps is mirrored on the other side with another pump so if ther's a problem, just switch the operation to the other standby pumps/machines (just like switching the train rail).. then after that to fix the broken stuff it's up to us la whether it requires any investigation..
