cso- After reading this central part of his original message: The rig has a BOP for these circumstances. BOP stands for Blow Out Preventer. All well bore components of the BOP are tested every few weeks for pressure integrity and the operation is not allowed to proceed if the BOP does not pass the test. The BOP is there for use when everything else fails. The BOP was used too late. Even after the gas was in the riser above the BOP, the diverter could have saved the rig, but was not used. I am sure Transocean would like to focus on the decisions which led to the failed cement plug and influx of gas into the well, but the fact remains the BOP should have been able to stop the gas at the seabed. The BOP is owned,operated and maintained by Transocean. No BP personnell are authorized to operate any BOP functions as far as I have ever seen. you don't feel that he's focusing on the BOP? Come on.
