Karoon Gas Australia Ltd advises that at 06:00 hours (WST) today, the BOP and marine riser were being pulled from seabed for repairs.
Since the last report, diagnostic testing of the BOP has continued. This further function testing has narrowed the mechanical parts believed to be the root cause of the BOP malfunction. Replacement parts are being secured and mobilized to the rig.
Upon completion of the replacement parts installation and successful function testing of the BOP, both on the surface and on the sea floor, drilling of the 8-1/2” hole section will commence.
The Transocean Legend semi-submersible rig is drilling the exploration well.
