The fishing operations were authorized by the federal government following a successful 48-hour ambient pressure test to assure that no oil will leak during the pipe removal procedure.
Following successful fishing operations and authorization from the National Incident Commander (NIC), BP will proceed with replacement of the original BOP with the Transocean Development Driller II (DDII) BOP.
In anticipation of a successful operation, the DDII set a storm packer and has unlatched its BOP from the second relief well site, BP said.
In the case fishing operations are unsuccessful, BP and the federal science team are developing contingency procedures, which will be carried out under the approval from the NIC.
