[BITList] BOP's

I wouldnt fancy being on the rig trying to land the the back up stack, 
it used to be bad enough trying to do a re-entry on a well after we had 
unlatched and moved off due to bad weather but we were only trying to 
latch on with the riser which had a re-entry cone plus subsea tv along 
with a transmitter beacons on the stack and receivers on the riser, 
suppose they can use the ROV's to fit these but in this case they will 
be dangling a stack over a producing well and doing it blind with all 
the rubbish coming out of the well Ive watched Red Adare and Boots & 
Coots do it a couple of times in Indonesia with varying success and that 
was on land rigs  it would be like sitting on a bomb up to on the rig
