BP and its partners made a series of cost-cutting decisions that ultimately contributed to the oil spill that ravaged the Gulf of Mexico coast over the summer, the White House oil spill commission has said.
In its final report on causes of the largest offshore oil spill in US history, the commission said BP and its collaborators on the doomed Macondo well had lacked a system to ensure their actions were safe.
"Whether purposeful or not, many of the decisions that BP, Halliburton, and Transocean made that increased the risk of the Macondo blowout clearly saved those companies significant time (and money)," the report said.
Created by US president Barack Obama in the midst of the BP spill, the panel is the first government-sanctioned group to wrap up its probe of the causes of the drilling disaster.
Charged with guiding the future of offshore drilling, the commission will release its full review of the spill and its aftermath next week.
Although the commission lacks authority to establish policy or punish companies, its conclusions could have a bearing on future criminal and civil cases relating to the spill.
The findings contradict its initial report in November, which found no evidence that Macondo project workers cut corners to save money.
After receiving criticism for that finding, the panel sought to clarify those comments, saying it did not mean companies involved with the accident had never sacrificed safety to save money.
A chart by the commission was later leaked by the media detailing decisions made while drilling the Macondo well that saved time, but increased risks.
Eventually, the panel made the document public and the final report included a similar chart. The conclusions released so far align with many previous comments from the panel, as well as initial results of another major probe conducted by a scientific panel.
The commission also concluded the Gulf spill was not an isolated incident caused by "rogue industry or government officials".
"The root causes are systemic and, absent significant reform in both industry practices and government policies, might well recur," the report said.
The report outlines major missteps by BP; by Halliburton, which oversaw cementing for the Macondo well; and by Transocean the owner and operator of the Deepwater Horizon rig.
BP is faulted for not using a "cement bond log" or another diagnostic tool to test stability of the cementing.
The report said BP's "fundamental mistake" was failure to exercise caution before relying on the cement as a barrier to the flow of oil and gas up the well.
BP was also blasted for various decisions made as it attempted temporarily to abandon the Macondo well.
BP's decision to displace mud in the riser pipe before setting a cement plug or another barrier "unnecessarily and substantially increased the risk of a blowout", the report said.
BP said in a statement that it supports the commission's efforts to determine the causes of the accident. "BP is working with regulators and the industry to ensure that the lessons learned from Macondo lead to improvements in operations ... in deepwater drilling," the company said.
