The U.S government issued their final report on the Gulf of Mexico oil spill, pinning most of the blame on BP, while also pointing to errors made by Halliburton and Transocean. The report said that BP was responsible for 21 of the 35 contributing causes of the Macondo well blow out, while sharing the blame for an additional eight. Investigators found that BP made a series of decisions that complicated cementing operations that may have led to the failure of the cementing of the well. The report said that BP failed to communicate decisions regarding cementing, increasing the operational risk of Transocean who was the contractor that owned the Deepwater Horizon rig.
However, investigators found that Transocean workers missed an opportunity to address the cement problems after misinterpreting a test of the wall’s barriers. Halliburton cemented the well, and worked with BP to design the project. The report said that due to the well being over budget, “BP sought to minimize these losses by reducing the volumes of cement it pumped into the well.”
BP issued a statement saying the company agrees with the core conclusions of the report noting that multiple causes contributed to the failure, pointing to errors by Transocean and Halliburton. Representatives from Transocean and Halliburton were unavailable for comment.
