US Offshore Program:

Prior to April 20, 2010, 25,000 wells had been drilled in US Federal waters over the previous 25 years without a single well control fatality, an offshore safety record that was unprecedented in the U.S. and internationally. Well control was the keystone of every operator and drilling contractor’s safety program and the Minerals Management Service regulatory program, which included a pioneering well control research facility at LSU, standards, prescriptive rules, and comprehensive training requirements.

The future of the offshore program was bright. The Obama administration had included an Atlantic OCS lease sale in the 5-year OCS Oil and Gas Leasing Program for 2010-2015. This would have been the first Atlantic sale since 1983. I participated in a hearing held by a Florida Senate committee that was seriously considering oil and gas leasing in Florida State waters. Even in California, there was some support, led by a group known as Stop Oil Seeps, for new offshore exploration and production .

Everything changed on April 20, 2010, when BP’s Macondo well blew out. Eleven workers lost their lives, the most in a single US offshore incident since 1968, when 11 died in a fire and explosion at West Delta Block 23. In the history of the US offshore program, only a 1964 gas blowout (Eugene Island Block 273) caused more fatalities (22). (There were also tragic helicopter crashes in 1977 and 1984 at South Marsh Island Block 128 and Eugene Island Block 190 that killed 17 and 14 offshore workers respectively.) The Macondo blowout was more than a safety disaster, it was also a pollution spectacular that dominated the news for the next 3 months.

Pre-Macondo BP:

As is often the case with large organizations, the BP story is complex. BP said all the right things about safety and environmental protection, and seemed to mean them and practice them. They had comprehensive safety and risk management programs. They were at the vanguard in promoting personal safety among employees including the now common (and sometimes a bit contrived) practice of opening meetings with safety messages. All of that was no doubt consistent with their “beyond petroleum” rebranding (2002). However, the corporate image was badly tarnished by the 2005 Texas City refinery explosion that killed 15 workers and a 5000 barrel pipeline spill on the North Slope of Alaska in 2006.

BP’s deepwater Gulf of Mexico exploration programs had been very successful. BP produced more oil in the 2 years prior to the blowout than any other US offshore operator – 117 million barrels in 2008 and 188 million barrels in 2009. Their 2009 oil production total is still the highest in history for any US offshore operator (something I hadn’t realized until I checked the figures for this post.)

The compliance record for BP’s production facilities in 2008 and 2009 was “beyond” excellent. While BSEE does not publish the details needed to distinguish INCs by facility and operation, my recollection is that inspection of the thousands of components on their production platforms did not result in even a single incident of non-compliance (INC) in 2008, and there were no production safety or pollution incidents. BP was named a finalist for the MMS SAFE Award to be presented at OTC in May, 2009. However, pointing further to their corporate inconsistencies, BP’s drilling compliance record was not as good, and qualitative feedback from MMS inspection personnel indicated some safety and compliance issues. This input may have been a hint at the drilling program management issues that surfaced after the blowout. In light of these concerns about BP’s drilling operations, Devon Energy was presented the National SAFE Award in the “High Activity Operator” category.

I retired from MMS on 1/2/2010 and was thus not involved in the deliberations for the 2009 SAFE Awards. I understand that BP was the leading candidate to be presented the award in May 2010. However, the way the program worked was that finalists in each category were named in advance, but the winners were not announced until the awards luncheon. The reasons for this approach were to build suspense and avoid a situation where the winning company was involved in a significant incident prior to the presentation. This had never been an issue in the 30 year history of this awards program.

In light of the tragic events of April 20, the 2010 SAFE awards luncheon was cancelled, as it most definitely should have been. That said, I remain a strong believer in recognizing safety achievement. The MMS SAFE Awards were the only offshore safety awards determined by the safety regulator based on incident and compliance data and input from inspectors, the people who are most familiar with each company’s operations and the effectiveness of their safety programs. The awards program drew attention to best practices, information sharing, and safety leadership. The recipients and all staff that contributed to the company’s success were rightfully proud of their achievement. You could not nominate yourself or be nominated for SAFE awards; only the companies with the best safety and compliance records were considered. Past performance is never a guarantee of future success, but MMS SAFE Award winners earned the recognition they received and continued to be top performers.

This week I’ll be posting background information, new details, and personal opinions about the April 20, 2010 Macondo tragedy. As a prelude, I wanted to share this touching tribute to the 11 men who died on the Deepwater Horizon. These American heroes gave their lives exploring for energy to power our economy. The video is introduced by singer Trace Atkins, a former Gulf of Mexico rig worker.

INCIDENT DISCLOSURE 2022

NEAR MISS ON THE HIBERNIA PLATFORM

March 25, 2022

Hibernia Management and Development Company (HMDC) has reported that on March 20, 2022 a crane on the Hibernia Platform was lifting a mini container when it made contact with a scaffold hoarding. There were three people working inside the hoarding at the time of contact. No one was injured and there was no damage to the scaffold hoarding.

West pedestal crane operations were halted and HMDC has initiated an investigation to determine the potential classification of the incident.

C-NLOPB Safety Officers were already scheduled to travel to the Hibernia Platform in the coming days and will follow up with HMDC to review this incident and the near miss that occurred on March 15.

The C-NLOPB is also monitoring HMDC’s investigations of these incidents.

123 workers lost their lives in the North Sea.

Tiå går og di seie tiå lege adle sår
Men ein mista bror e sår som aldri gror
Kanskje vil dårr gå vinter og vår
Sei oss klart kor dokker står
Håpte på at han sko komma
At han sko komma hjem igjen

Time is gone, they said; time would heal all wounds
But to lose a brother is a wound that will never heal
It could take as long as the never-ending winter and spring [i.e., never]
I hope that he should come
That he should come home again

The International Regulators’ Forum (IRF) does a good job of compiling safety performance data for offshore oil and gas operations in member countries. Because these data are collected by the respective regulators and compiled in accordance with established guidelines, we consider the IRF compilations to be the most credible international incident summary data for the offshore industry.

BOE looked at the numbers for the IRF countries with the highest level of activity in terms of hours worked – Brazil, Norway, UK, and US. These countries accounted for 90% of the total hours worked in 2020, the last year for which data are available. The 2020 hours worked (millions) were also relatively similar for the 4 countries: Norway – 41.2, UK – 42.4, US – 50.4, Brazil – 50.7. The differences in hours worked were somewhat greater in the prior years, but not dramatically so.

We charted the fatality and lost-time (>3 days) data (below). Our intent at this point is to draw attention to the IRF data sets, not to assess and compare performance. We do think the overall safety performance in these and other IRF countries, while far from perfect, is quite good given the hundreds of millions of hours worked, complexity of operations, logistical challenges, and difficult operating environments. We recommend that the IRF prioritize the timely posting of these data, and begin providing causation information so that companies and other interested parties can better identify performance issues and safety trends.

Trinity Spirit FPSO

Six weeks after the Trinity Spirit fire, there is still no public accounting of the number of fatalities and injuries. The initial reports were incomplete and inconsistent, even with regard to the number of people on the vessel at the time of the incident.

SEPCOL, the FPSO operator, no longer has a website and has issued no public statements on the incident since the day afer its occurrence. The company’s status is thus uncertain. The Nigerian Upstream Petroleum Regulatory Commission website only advises that the fire was extinguished as of 4 February.

The absence of timely information on major incidents reflects poorly on the offshore industry and those who regulate it. This is not just a Nigerian issue. It’s past time for an international standard that identifies incident information to be publicly disclosed and specifies the timeframes and methods for releasing this information.

This useful SafeOCS report summarizes and itemizes well control equipment failures associated with well operations on the Gulf of Mexico OCS in 2020. Of particular note was the absence of any loss of containment (leak of wellbore fluids) events in 2020 or the prior two years.

Unfortunately, there appear to be significant reporting gaps despite the fact that reporting of these data is required by regulation (30 CFR 250.730(c)). The reporting issues are particularly serious for surface systems (surface BOP and associated equipment). Per SafeOCS, surface rig reports were received from less than 50% of active operators and rigs. Reporting for subsea systems (subsea BOP and associated equipment) was much better with 85% of the active rigs represented.

Of further concern with regard to the reporting of surface equipment events, the data indicate only 5.3 events per 1000 hours for surface systems vs. 71.5 for subsea systems. While subsea systems are more complex, the cost of pulling and repairing subsea equipment dictates newer, better maintained equipment. As a result, surface BOPs have historically had higher failure rates than subsea BOPs. The data below are from a presentation to MMS approximately 15 years ago. Both the Sintef and OOC data show higher failure rates for surface BOPs.

The SafeOCS team did a very good job of analyzing the reports and presenting the data. However, the reporting issues need to be investigated and resolved to get maximum value from this very important work.

This is inexcusable if true:

A federal investigation into the October oil spill that paved the Orange County coast has been stalled for several months as authorities await approval to cut, remove and analyze part of the ruptured pipeline.

LA Times

Coast Guard and National Transportation Safety Board investigators currently have to rely on video captured during underwater pipeline inspections. Without a more detailed forensic examination of the damage in a lab, investigators won’t know whether to continue with their original investigation or move the investigation in a new direction.

LA Times

It’s not good when bureaucratic processes stall an important investigation. Hopefully the responsible agencies will be sufficiently embarrassed to get the investigation moving.

The New York Times calls out the CDC for not releasing Covid data:

Kristen Nordlund, a spokeswoman for the C.D.C., said the agency has been slow to release the different streams of data “because basically, at the end of the day, it’s not yet ready for prime time.” She said the agency’s “priority when gathering any data is to ensure that it’s accurate and actionable.”

Another reason is fear that the information might be misinterpreted, Ms. Nordlund said.

“The C.D.C. is a political organization as much as it is a public health organization,” said Samuel Scarpino, managing director of pathogen surveillance at the Rockefeller Foundation’s Pandemic Prevention Institute. “The steps that it takes to get something like this released are often well outside of the control of many of the scientists that work at the C.D.C.”

BOE and others interested in offshore safety have expressed similar frustration over delays in the release of incident data and reports by BSEE and the Coast Guard, and the limited inspection data that are publicly available. As is the case with the CDC, we suspect these issues have more to do with bureaucratic obstacles than technical limitations or staff reluctance.
