‘Piper Alpha disaster was the best and worst day of my life’ – Ed Punchard

Ed Punchard today; Piper Alpha survivor

JL Daeschler shared a London Sunday Times piece about the Piper Alpha fire that killed 167 workers, the worst tragedy in the history of the offshore industry. We were troubled by the headline, because it seems inconceivable that any UK offshore worker could call July 6, 1988, the best day of their life. However, Punchard helped a number of workers escape the fire, so his mixed message is somewhat understandable.

Lord Cullen’s comprehensive inquiry into the Piper Alpha tragedy challenged traditional thinking about regulation and how safety objectives could best be achieved, and was perhaps the most important report in the history of offshore oil and gas operations. That report and the US regulatory response to the tragedy are discussed in this post.

BSEE’s new downhole commingling rule, which responds to a Congressional mandate, is contrary to Cullen’s Safety Case principles in that it puts the burden of proof on the regulator to conclusively demonstrate that a potentially hazardous operation is unsafe. This is exactly the opposite of the approach recommended by Cullen. It’s also the first time in the history of the OCS program that Congress has dictated approval of complex downhole operations. More on this in a later post.

… Union Oil Company’s reckless well plan forever scarred the U.S. offshore program. Learn more about the details.

Santa Barbara blowout

Examinations of the Santa Barbara, Montara, and Macondo blowouts, the Piper Alpha fire, and other major incidents should be a part of every petroleum engineering curriculum, and should be mandatory for those who conduct and regulate offshore oil and gas operations.

There is no better learning experience than studying the failures that had such enormous human and economic consequences.

35 years ago today, fires and explosions destroyed the Piper Alpha platform in the North Sea and killed 167 workers. We must never forget this tragedy.

The Piper Alpha fire was the worst disaster in the history of offshore oil and gas operations and sent shock waves around the world. Eight months later another interactive pipeline-platform fire killed 7 workers at the South Pass 60 “B” facility in the Gulf of Mexico. A US Minerals Management Service task group reviewed the investigation reports for both fires and recommended regulatory changes with regard to:

  1. the identification and notification procedures for out-of-service safety devices and systems,
  2. location and protection of pipeline risers,
  3. diesel and helicopter fuel storage areas and tanks,
  4. approval of pipeline repairs, and
  5. location of ESD valves on pipelines.

Paul Schneider and I wrote a paper on the task group’s findings and that paper was published in Offshore Operations Post Piper Alpha (Institute of Marine Engineers,1991). The proposed regulations that followed summarized these findings and can be be found at this Federal Register link.

Lord Cullen’s comprehensive inquiry into the Piper Alpha tragedy challenged traditional thinking about regulation and how safety objectives could best be achieved, and was perhaps the most important report in the history of offshore oil and gas operations. Per Cullen:

“Many current safety regulations are unduly restrictive because they impose solutions rather than objectives. They also are out of date in relation to technological advances. Guidance notes lend themselves to interpretations that discourage alternatives. There is a danger that compliance takes precedence over wider safety considerations and that sound innovations are discouraged.“

Cullen advocated management systems that describe the safety objectives, the system by which those objectives were to be achieved, the performance standards to be met, and the means by which adherence to those standards was to be monitored. He called for safety cases that describe major hazards on an installation and provide appropriate safety measures. Per Cullen, each operator should be required in the safety case to demonstrate that the safety management systems of the company and the installation are adequate to assure that design and operation of the platform and its equipment are safe.

Scottish Hazards

In terms of the total number of fatalities, the Piper Alpha fire was the worst disaster in the history of offshore oil and gas operations and sent shock waves around the world. Eight months later another interactive pipeline-platform fire killed 7 workers at the South Pass 60 “B” facility in the Gulf of Mexico.

Was MMS Visionary?

Posted in Regulation, tagged , , , , , on January 31, 2011| Leave a Comment »

Some post-Macondo commentary has characterized MMS employees as regulatory Neanderthals who couldn’t see beyond their checklists, had no understanding of operating systems and the associated process-safety risks, and were dreadfully behind their industry and regulatory peers. The reality is quite different, as those who worked with or for the MMS know. Someone who did both, Doug Morris, an engineer and attorney with extensive industry and regulatory experience, shared this excerpt from an April 1988 Federal Register notice. The Notice publishes the outcome of a 5-year regulatory review that updated and consolidated all MMS operating requirements for offshore oil and gas operations. One of objectives was to establish performance standards for all types of operations to encourage innovation and discourage a “compliance mentality.” Keep in mind that this Notice was published before Piper Alpha, the Cullen report, and the worldwide wave of regulatory reform that followed.

The following summarizes the major changes from current rules:

(1) Performance Standards. Performance standards were added which describe the safety, environmental, property, and resource protection goals intended to be achieved by specified design and engineering requirements. These additions are intended to identify the purpose of the detailed requirements and thus provide a basis for approving an alternative method for achievement of the stated purpose. New, different, better, and more efficient techniques and practices are intended to be available to lessees on the basis of these performance standards.

(a) Performance Requirements. A “Performance requirements” section was added. This section clarifies that the specific detailed requirements of the rule do not preclude the approval for use of alternate or new techniques, procedures, equipment, or activities when the lessee satisfies MMS that the proposed alternate approach provides equal or greater protection than that provided by the requirements specified in the rule. The establishment of performance standards in addition to specific detailed requirements is intended to remove obstacles to innovation and ensure that MMS’s regulations are not unnecessarily prescriptive.
