Platform Harmony jacket

An excellent paper by John Smith and Bob Byrd is attached.

The authors recommend the operators of large OCS platforms offshore California and in the Gulf of Mexico who propose to partially remove platform jackets prepare Comparative Assessments to support their decommissioning applications. The Comparative Assessments can also be prepared to support the case for allowing partial removal of smaller platform jackets and allowing pipelines and drill muds and cuttings to remain in-situ.

NOPSEMA has kindly provided links for the slides presented at the 3-4 October International Regulators’ Forum Offshore Safety Conference in Perth, Australia. They will be uploading the video recordings at a later date.

On day 2 (stream 2) Bryan Domangue (BSEE) presented updated data on the progress that is being made in plugging inactive wells and decommissioning idle platforms (see the charts pasted below). In the following session, Bryan made an interesting presentation on the capping stack deployment exercises in the GoM (picture below).

For excellent slides on investigation and sharing the lessons learned, see session 9 (day 2, stream 1).

Excellent Guardian article featuring my former colleague Dr. Ann Bull and Dr. Milton Love from the University of California at Santa Barbara.

According to a 2014 study they (Bull and Love) co-authored, the rigs were some of the most “productive” ocean habitats in the world, a term that refers to biomass – or number of fish and how much space they take up – per unit area. The research showed the rigs to be about 27 times more productive than the natural rocky reefs in California.

The Bureau of Ocean Energy Management (BOEM) is extending the public comment period on our notice of proposed rulemaking (NPRM), “Risk Management and Financial Assurance for Outer Continental Shelf Lease and Grant Obligations,” by 10 days.

Federal Register

These comments were submitted 7 days (now 17 days) early 😀

Federal regulations: “decades to draft, days to comment”

The attached comments were submitted to BOEM via Regulations.gov. The comments address specific provisions of the proposed rule and include a recommendation to hold companies fully accountable for their lease transfers, but not for subsequent transfers in which they are not a party.

Do I get a t-shirt for being one of the first 2000 entries? 😀

1137 comments to date per Regulations.gov. This would imply one or more organized commenting campaigns.

I will share my comments on this blog after they have been submitted.

For the first time in the history of the US OCS program, Federal ontracts have been awarded for the decommissioning of facilities in the Matagorda Island area of the Gulf of Mexico. The use of taxpayer funds for this purpose should be an embarrassment for the offshore industry and its regulators, past and present.

Rather than touting these contracts, the regulators should be explaining how this happened and how it will be prevented in the future. Fortunately, BOEM’s proposed decommissioning financial assurance rule is open for comment until the end of this month, so we have an opportunity to provide input.

Matagorda Island Gas, the company whose wells the public will be plugging, had a poor compliance record, and is another example of why compliance should be a primary factor in determining supplemental financial assurance requirements.

For the first time in the history of the US offshore oil and gas program, taxpayers will be funding the plugging of OCS wells. This should be viewed as a collective failure by government and industry. Nearly 34 years have passed since the Alliance bankruptcy, the first of many wake-up calls, and we still haven’t figured this out.

Per BSEE’s recent announcement, Federal funds will be used to plug wells in the Matagorda Island (MI) area of the Gulf of Mexico (see map below). Based on a BSEE presentation and BSEE borehole data, these wells were drilled by Matagorda Island Gas Operations LLC, a company that filed for bankruptcy in 2014.

Prior to the bankruptcy filing, Matagorda Island Gas was cited for 112 violations on 108 inspections. This INC/inspection rate is approximately double the Gulf of Mexico (all operators) rate in a typical year (0.52 in 2022), and is 4 to 25 times higher than the rate for the 2022 Honor Roll companies.

In a draft rule published on June 29, 2023, BOEM proposes to discontinue using a company’s record of compliance in determining the need for supplemental financial assurance for decommissioning. BOEM’s full explanation for this surprising change is pasted at the end of this post.

Opposing view:

  • BOEM should be more attentive, not less, to safety performance and compliance data. If they were, taxpayers would have been better protected from the risks associated with the lease acquisitions by Fieldwood, Cox, Black Elk, Signal Hill, and others, and their subsequent bankruptcies.
  • Safe operations, as reflected in compliance and performance data, are critical to a company’s financial success.
  • BOEM wrongly infers that Incidents of Noncompliance (INCs) are solely dependent on the number and complexity of facilities. Decades of normalized compliance data have told us that there are marked differences among operators in terms of compliance and safety performance. Companies at the bottom of the performance table don’t usually survive.
  • Accidents are not mere matters of chance; management and culture matter.
  • Honor Roll companies, large and small, have superior compliance records, and in 2022 these companies had 50-90% fewer INCs/facility-inspection than the Gulf of Mexico average.
  • Does BOEM expect noncompliance leaders to be concerned about decommissioning obligations? The record shows that they are not.
  • Cox’s 2023 bankruptcy was predictable given their past safety performance. In 2022, Cox was a violations leader by any measure, and was responsible for 9 of the 30 safety incidents that were significant enough to require investigation by BSEE.
  • Fieldwood’s terrible 2021 safety performance has been discussed, and there was ample evidence of performance problems prior to their bankruptcy declaration in 2018. In 2016 and 2017 Fieldwood was, by far, the GoM violations leader with 818 INCs, 401 of which required a facility or component shut-in.
  • Ironically (or maybe not), the only other company that was even in the same noncompliance ballpark as Fieldwood in 2016 and 2017 was future Cox affiliate Energy XXI GOM. Energy XXI earned 465 INCs (240 shut-ins) during that 2 year period. Did BOEM object to or otherwise comment on the 2018 Cox-Energy XXI merger?
  • Black Elk Energy was new in 2007 and quickly became a violations leader. Between 2010 and 2012, BSEE cited Black Elk 415 times. 218 of these violations were serious enough to require facility or component shut-ins. On November 16, 2012, explosions at Black Elk’s West Delta 32 platform killed 3 workers, and 2 others suffered severe burns. Criminal charges and a complex bankruptcy followed. BSEE records show 1107 INCs during the company’s short history, 464 of which required facility or component shut-ins.
  • The rapid growth of Fieldwood, Cox, and Black Elk was in part facilitated by lax lease assignment and financial assurance policies. Operating companies should have to demonstrate that they can operate safety and comply with the regulations before they are approved to acquire more properties.
  • The Signal Hill saga was documented nearly 2 years ago, and none of the questions raised in that post have been answered. Violations data and inspector feedback predicted the Signal Hill/POOI failure. Nonetheless, and despite the objections of regional staff, Signal Hill was allowed to tap into its decommissioning account to cover operating expenses. Responsibility for decommissioning Platforms Hogan and Houchin is still uncertain.
  • Bankruptcy has been used to avoid or transfer decommissioning obligations. In that regard, Chevron’s comprehensive objection to Fieldwood’s restructuring plan is telling.
  • Given that BSEE, not BOEM, is responsible for safety and compliance, I sincerely hope that regulatory fragmentation was not a factor contributing to BOEM’s decision to discontinue the use of compliance data in determining financial assurance needs.

BOEM’s explanation for the proposal to eliminate the record of compliance criterion:

BOEM also proposes to eliminate the existing “record of compliance” criterion found in the current version of § 556.901(d)(1)(v). BOEM has determined that the number of INCs a company receives correlates with the number of OCS properties it owns, not its financial stability, and therefore, BOEM has concluded that it is not an accurate predictor of its financial health. BOEM reviewed BSEE’s Incidents of Non-Compliance (INCs) records and its Increased Oversight List, which represent BSEE’s cumulative records of violations of performance standards on the part of OCS operators and lessees and determined that the number of incidents of non-compliance typically increases with the size and complexity of the operator’s or lessee’s operations, including the ratio of incidents to number of components. Because larger companies (regardless of credit score) tend to have more properties and components and therefore more INCs, BOEM determined that record of compliance criterion does not accurately predict financial default. BOEM’s review of this information confirmed the feedback BOEM received in response to the 2016 NTL, namely that companies with a large number of properties and facilities tended to receive a large number of INCs and had more individual properties on the Increased Oversight List. BOEM specifically requests comments regarding the use of fines and violations as a criterion in the determination of a company’s ability to fulfill decommissioning obligations, and any data or analysis addressing any correlation between the number of violations and the risk of financial default. BOEM also requests comments on whether the elimination of the INC’s criteria would create a disincentive to comply with regulations. BOEM also requests comment on whether or not the cost of decommissioning is likely to increase based on the type, quantity, and magnitude of previous violations.

On a related note, BOEM/BSEE should consider a followup to the John Shultz thesis which found that INCs are a very good predictor of accidents and spills.
