For (1) and (2), the blind rams can be replaced by ,pipe, rams to allow the drill string to be pulled out through the upper rams while the lower rams are kept as back up. For (1), if the drillpipe is in the well and a leak occurs at the mud cross (or the kill line or the choke line), the well can be closed with the ,pipe, rams while the repair job is carried out.
