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?

In their comments on the Coast Guard’s Deepwater Horizon Joint Investigation Team Report, Transocean made these statements about BOP maintenance standards incorporated in MMS drilling regulations:

By glossing over the contours of the regulatory language, the Draft Report unilaterally converts API Recommended Practice 53 from an advisory guideline into a mandatory requirement. Notwithstanding the Draft Report’s insistence otherwise, the API’s recommendation that the BOP “should” be disassembled and inspected according to the manufacturer’s guidelines is not mandatory. The API clarifies that the word “should” indicates a recommended practice for which a comparably safe alternative is available or which may be impractical or unnecessary in some conditions. In contrast, to denote a recommended practice that is “advisable in all circumstances,” the API uses the word “shall.” The API also emphasizes that “the formulation and publication of API standards is not intended in any way to inhibit anyone from using any other practices.” Though it recommends specific practices, API acknowledges that “equivalent alternative installations and practices may be utilized to accomplish the same objectives.” On its face, the language of API RP 53 makes clear that the recommendation that the BOP “should” be disassembled and inspected in accordance with the manufacturer’s guidelines is a recommendation, and nothing more.

Although the MMS regulations governing BOP maintenance incorporate API RP 53 sections 17.10 and 18.10 by reference, this does not convert the API’s recommendations into a mandatory requirement. As the MMS has clarified, “[t]he legal effect of incorporation by reference” is merely that “the material is treated as if it were published in the Federal Register.”

Treating API RP 53 as if it had been published in the Federal Register does not imbue its language with more regulatory significance than it had before. The API’s recommendations regarding BOP maintenance—as well as the API’s acknowledgement that alternative practices “may be utilized to accomplish the same objectives”—remain recommendations, not requirements.  Transocean’s complete comments are posted on their website.

I’ll withhold my comments on the above statements, except to say that my opinion differs substantially from Transocean’s.

More significantly, these and other recent industry and government comments demonstrate the complexity of standards policy issues. How are standards most effectively applied by operators in formulating safety management programs, operating plans, and safety cases? Contractors? How should deviations from standards be assessed and documented? How should regulators use standards? To what extent should standards be incorporated into regulations? What is the appropriate role for regulators in standards development? These issues may prove to be more challenging than updating technical requirements. Stay tuned!

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.

Hundreds of witnesses expected.

The trial won’t proceed quickly, if the parties call all the witnesses on their lists.

Transocean’s roster of 304 included 82 of its own employees, 87 from oil company BP, and 18 from cement contractor Halliburton.

BP listed 71 witnesses from Halliburton, 110 others, plus anyone else who has been or will be deposed.

The United States listed 56 from BP, 32 from Halliburton, and 76 others.

Today, the International Oil and Gas Producers (OGP) released the Global Industry Response Group (GIRG) reports.  GIRG was formed last July with the goal of better managing offshore safety risks. The organizational structure is illustrated below.

Deepwater Wells: Lessons and Recommendations focuses on the critical prevention programs, and is perhaps the most important of the GIRG reports. Since Macondo, the GIRG team and other industry committees have worked diligently on well planning and integrity issues, and are commended for their outstanding efforts. However, the recommendations presented in the GIRG report are surprisingly modest, and do not reflect the technological and management innovation that industry has demonstrated in pioneering offshore development.  The recommendations fail to break new ground, lack specifics, and, in some cases, appear to be a step backward. In short, the oil and gas industry is capable of much more.  Initial comments follow:

  • Incident data (problem): The absence of comprehensive and verified incident data is one of the “systemic” industry weaknesses identified by the National Commission. OGP has tried to address this problem for years, but has not had the industry-wide support needed to develop a credible program. GIRG has wisely recommended a Wells Expert Committee (WEC) to review selected incident data. However, the recommended program suffers from the same weaknesses that constrain existing OGP reporting programs. OGP must rely on “encouraging” its members to participate voluntarily, and non-members are not included. This type of voluntary program was not good enough before Macondo/Montara, and is certainly not good enough now.
  • Incident data (solution): Industry and regulators need an ironclad commitment that all operating companies will submit incident data in accordance with defined protocols. Contractor data must be included. Companies should execute binding agreements with OGP, or some other entity, to provide this information. The data must be managed by a completely independent entity that cannot, in any way, be directed by an industry advocacy group. Regulators and other independent representatives should be included on the management committee. Regulators should prohibit companies that don’t agree to submit these data from from operating within their jurisdictions. A comprehensive incident reporting and data management system is long overdue, and continued delays are not acceptable.
  • Montara: While GIRG is supposedly in response to both Macondo and Montara, the latter seems to have been largely ignored. The deepwater theme does not apply to the Montara platform, which was in only 80m of water. Despite the post-Macondo focus on water depth, shallow water was arguably a more significant contributing factor to the Montara blowout (batched completions using a cantilevered jackup, mudline suspensions, and two-stage platform installation) than deep water was at Macondo. Also, well capping, which was feasible and ultimately successful at Macondo, could not even be attempted at Macondo because of the manner in which these platform wells were suspended. Finally, GIRG  ignores the special gas migration and kick detection issues associated with horizontal completions like Montara, and the relief well rig availability and release issues that were never fully addressed during the Montara inquiry.
  • Emergency worldwide notification system: In conjunction with the incident reporting system, industry needs an emergency notification procedure that goes beyond safety alerts and requires the immediate attention of every operator and wells contractor. During the Montara inquiry, worldwide attention should have been drawn to the inability of the Montara operator to identify a hydrocarbons influx through the shoe track and into the production casing. Could an effective notification system have prevented Macondo? No one can say for sure, but the probability of a blowout at Macondo would have been greatly reduced if key BP and Transocean personnel had participated in discussions about Montara and the importance of proper negative pressure tests.
  • Dependence on regulator: On page 21 of the report, GIRG recommends that a company “carry out a more extensive programme of self-audit” when there is a lack of competent regulatory oversight. An operator should never depend on the regulator to verify its well or management programs, and should never relax its programs regardless of the level of regulation. Detailed regulatory reviews of specific drilling or management programs are never a substitute for operator diligence. Did the operators at Montara and Macondo rely on the regulator to protect them from themselves? Read the official investigation reports and make your own judgement.
  • Best practices: GIRG recommends “refraining from using the term ‘best industry practice’ until this definition is clarified; we prefer ‘good oilfield practice’ for the time being.”  Isn’t the clarification of best practices the role of groups such as this and industry standards committees? This attitude explains some of the technical recommendations in this report which may be “good oilfield practices,” but fail to raise the bar for safety achievement. Would you be satisfied with “good” if  family members were working on rigs or if operations were conducted off your coast? While “best practices” vary depending on the conditions and circumstances, it’s industry’s responsibility to identify those practices, and industry and regulators must set the bar high and keep raising it.
  • GIRG recommends established practices: Some of the GIRG recommendations, such as the “two-barrier” policy have been standard practice for most operators for years.
  • API RP 75: There are numerous endorsements of RP 75 as an important reference for management systems covering the design of wells and other activities.  RP 75 was a reaction to an MMS regulatory initiative 20-years ago to impose safety management requirements on offshore operators. BP, Transocean, and PTTEP had management systems that were generally consistent with the guidance in RP 75. GIRG needs to go beyond RP 75 and focus on improvements that will make safety management systems more effective.
  • API Bulletin 97, Well Construction Interface Document (WCID): Despite the complete absence of public attention, this is perhaps the most important post-Macondo initiative. It’s thus particularly disappointing that this document is now five months late. How does GIRG recommend the use of a document that is not complete and has not yet (to the best of my knowledge) even entered the balloting process? Another recommended and highly important document, updated RP 96 – Deepwater Well Design, has also yet to be finalized.
  • BOP recommendations: Nothing new or innovative is offered by GIRG. The report calls for 2 shear rams, but only one need have sealing capability, which means that the Deepwater Horizon stack met the GIRG specification. While many BOP advances require additional study, some (such as real-time function and pressure monitoring systems) already exist. Other GIRG technology recommendations are rather timid and generally in the form of suggestions for future study (e.g. study cement bond log technology).
  • Training: This section of the report is good, but doesn’t address deficiencies identified in the Montara inquiry and reviews of historical blowout data. Montara and other accidents have demonstrated that senior rig personnel may have limited understanding about well planning and construction practices. These topics are not covered in well control training programs. How does industry plan to address this major deficiency? While well planning is the responsibility of the operator (often a separate group than is represented on the rig), well control decisionmaking requires a fundamental understanding of well construction practices.  Also evident in the Montara testimony was the total absence of understanding on the part of operator, drilling contractor, and cementing personnel about the historical causes of blowouts. The cementers at Montara were unaware that gas migration/influxes during cementing operations were a leading cause of blowouts. Training programs need to be expanded to provide for the discussion of past accidents and how they could have been prevented.

Reuters article

“For us, the major goal is to prevent these major accidents from happening,” said Fidel Ilizastigui Perez, an official of Cuba’s Office for Environment and Nuclear Safety Regulation.

“The companies must show that they meet all international standards,” he told the conference in Port of Spain.

Perez said Cuban officials had studied and already implemented oil industry safety practices from Britain and incorporated others from the United States.

Mr. Perez participated in the 2005 International Regulators’ Offshore Safety Conference in London and made a very favorable impression.

Dan Whittle, a senior attorney at the U.S.-based Environmental Defense Fund, said the Cuban government appeared to be taking the safety issue seriously because of the potential economic benefit of the project.

“Cuba has a lot at stake,” he said. “They’re doing the best they can with limited resources and with obstacles to access those resources.”

“I think we’re seeing the beginning of a more international dialogue on what the Cubans are planning,” he added.

Sensible comments from the EDF.

Also, Cuba and the Bahamas have agreed on a maritime boundary.

“Is there likely to be litigation over new drilling permits? You bet there is,” said David Petit, a senior attorney with the Natural Resources Defense Council.

“We’ll definitely litigate it,” Kieran Suckling, executive director of the Center for Biological Diversity, said of the federal approval of Shell’s plan. “It’s patently illegal.”
