Animation of Transocean’s BOP analysis

Transocean’s BOP Defense:

Forensic evidence from independent post-incident testing by Det Norske Veritas (DNV) and evaluation by the Transocean investigation team confirm that the Deepwater Horizon BOP was properly maintained and did operate as designed. However, it was overcome by conditions created by the extreme dynamic flow, the force of which pushed the drill pipe upward, washed or eroded the drill pipe and other rubber and metal elements, and forced the drill pipe to bow within the BOP. This prevented the BOP from completely shearing the drill pipe and sealing the well.

In other words, Transocean contends that properly maintained BOPE was not up to the task of shutting-in and securing a high-rate well. If true, this finding has significant implications for the offshore industry.  I’m looking forward to reading the government’s findings on the BOP failure when the Joint Investigation Team report is issued next month.

BP settled Macondo litigation with Weatherford, manufacturer of the float equipment equipment used in the Macondo well. The failure of this equipment was a key contributing factor in the Macondo blowout. Under the agreement, Weatherford will pay BP $75 million.  This money will be applied to the $20 billion Macondo trust fund.

Weatherford is the first of BP’s contractors to formally agree with BP that the entire industry can and should learn from the Deepwater Horizon incident. Accordingly, Weatherford has committed to working with BP to take actions to improve processes and procedures, managerial systems, and safety and best practices in offshore drilling operations. BP and Weatherford will encourage other companies in the drilling industry to join them in this improvement and reform effort.

Comments:

  1. $75 million seems like a rather modest payment by Weatherford given the magnitude of Macondo damage costs. BP will “indemnify Weatherford for compensatory claims resulting from the accident.”  Presumably, Weatherford’s sales agreements provide good legal protection.
  2. One of the root causes of the Montara blowout was also a float collar failure. That float collar was also supplied by Weatherford.  I’m surprised that this common cause and supplier have received almost no attention. Of course, no one has paid much attention to Montara, either before or after Macondo. Had more attention been paid to the Montara inquiry, Macondo might have been avoided.  (Note that most of the post-Macondo commentary still implies that deep water is the threat even though Montara was in 80 m of water and the root causes of Macondo were not water depth related).
  3. When do we learn more about the “improvement and reform effort” described in the quote above?

Resources Minister Martin Ferguson is determined to establish a single national regulator after the Montara oil spill in the Timor Sea leaked oil and gas condensate for more than two months in 2009.

The WA government is at odds with Mr Ferguson over plans for a national regulator and wants to maintain responsibility for oversight of the industry in the state.

Senator Eggleston and Senator David Bushby said the federal government had introduced the legislation to parliament before concluding ongoing negotiations with the WA government. Herald Sun

Meanwhile, still no news regarding any penalties for Montara operator PTTEP.  Will there be none?

High-ranking congressmen made a concerted effort to financially distance themselves from BP in the aftermath of the Deepwater Horizon oil spill, either by reducing or altogether dumping their stock holdings, according to a Center for Responsive Politics analysis of lawmakers’personal financial disclosure documents released Tuesday. 

House Speaker John Boehner (R-Ohio) and Sen. John Kerry (D-Mass.) gave up all or a significant amount of their holdings in BP after the 2010 spill, which leaked an estimated 205 million gallons of oil in the Gulf of Mexico and killed 11 oil platform crew members in the initial explosion. Open Secrets Blog

Financial decision? Moral leadership? Fear of guilt by association? Washington front-running? Political weakness? I wonder where they reinvested their money.

More on lawmakers’ finances.

Because of recent involvement with products and systems that have Safety Integrity Level (SIL) ratings, I read the comment (below) in the PSA Deepwater Horizon review with interest. While administrative and effectiveness issues must be carefully assessed, the application of SIL should be part of the BOP performance dialogue.  SIL ratings may also be appropriate for entire well control or well integrity systems.

Today’s requirements stipulate a risk analysis for the control system of a drilling BOP, with specified minimum requirements for its safety integrity level (SIL). As a result of the DwH incident and of the fact that blowouts are not confined to drilling operations, the question is whether such an analysis, with a specified minimum SIL level, should also apply to all types of BOPs, including well-intervention models. In addition, consideration should be given in this context to whether other control and management systems related to well integrity/control exist which should be subject to such requirements.

A month ago, BOE posted a list of major accidents for which no official company or government reports had been released.  Below is the latest update on these accidents. If you have updated information, or if there are other events that should be added to the list, please let us know.

The following recent accidents are on our “watch list.”  Accidents are added to the “missing report list” when six months have elapsed since the accident.

From the standpoint of post-Macondo safety and regulatory issues, this concise summary is the most comprehensive and useful report that I have read since the blowout.

I have pasted (below) comments about information management – one of the many important topics considered in the report – and hope you take time to read the entire summary. It is only 12 pages.

Conducting a critical review of the information used to manage major accident risk is one of the measures relevant for the companies. This work could include an assessment of
 the relevance, reliability and modernity of the indicators used to follow up risk trends
 inappropriate use of indicators, incentives and reward systems
 the need for better indicators and other information about the business which can be used to secure an early warning about a weakening in safety-critical barrier elements.
The PSA is of the opinion that the quality of information applied in managing major accident risk is also a question of what overview the players have of their own business, and thereby a question of the players’ own control. The PSA assumes that managing major accident risk cannot be outsourced. In light of the DwH accident, it could be relevant for the companies to review the processes intended to provide the necessary information about the business, assess in part how these processes support a culture of accountability and how various management and audit functions, third-party verifications and so forth contribute in this connection.

Thanks to a reader, we have obtained a copy of a report on the Jack Ryan crane failure (August 2010) that killed one worker and injured three offshore Nigeria. As BOE readers know, we have been pursuing information on this accident for months.

At BOE our highest priority is drawing attention to and disseminating information on offshore accidents.  In that regard, we greatly appreciate the support we have received from readers.

Excerpt:

We understand that Total is conducting an inquiry, and assume that Transocean has also investigated this accident. We hope those reports are made publicly available.

Aban Pearl listing off Trinidad in August 2009

While our interest in the sinking of the Aban Pearl pertains to what went wrong and why, former PDVSA board member Gustavo Colonel continues to question Aban Pearl contracting irregularities. Is PDVSA refusing to release the report on the Aban Pearl sinking so as not to draw further attention to these contracting issues?

The whole Board is responsible for the loss of about 800,000 barrels per day of oil production; for the fraudulent certification of “proven oil reserves” in the Orinoco heavy oil region; for the irregular contracting, with a ghost company, of the offshore drilling barge Aban Pearl for twice the amount really paid to the owners of the barge; for the importing of 180,000 tons of food that later went to rot in Venezuelan ports but provided some of the members of the board with millions of dollars in criminal profits; and in numerous other corrupt practices that are well documented.

Like the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling, the Montara Commission of Inquiry, the Norwegian government, and leading safety and regulatory authorities around the world, the IADC recognizes the risks associated with complex, multi-agency regulatory regimes. A single authority should be responsible and accountable for safety and pollution prevention at offshore facilities, and should draw on the expertise of other agencies and organizations as necessary to achieve performance objectives. 

The safety and environmental  risks associated with fragmented or compartmentalized regulation include gaps, overlap, confusion, inconsistencies, and conflicting standards. Industry and governmental personnel spend too much time coordinating with multiple parties and not enough time managing safety and environmental risks.

Link to IADC comments.  Key quotes:

IADC continues to be concerned by seemingly duplicative regulatory requirements imposed by the Coast Guard and BOEMRE, particularly where the agencies appear to have divergent views regarding the placement of regulatory responsibility.

One cannot holistically address safety when faced with the unyielding and overlapping demands of multiple narrowly-focused regulatory agencies.
