Attached is an excellent Scientific American article featuring BOE contributor and decommissioning specialist John Smith, former colleague and marine biologist Dr. Ann Bull, and Dr. Milton Love, the leading authority on California’s offshore platform ecosystems.

I had the pleasure of taking a highly informative boat tour around Platform Holly with Dr. Love and a group of international visitors. Holly, which is pictured at sunset in the BOE header, is among the platforms awaiting decommissioning.

Dr. Love on the total removal of California offshore platforms:

“As a biologist, I just give people facts,” he says. “But I have my own view as a citizen, which is: I just think it’s criminal to kill huge numbers of animals because they settled on a piece of steel instead of a rock.”

Hywind Scotland, Equinor

Equinor reports that all 5 Hywind turbines have been returned to service after being towed to Norway as part of a 4-month maintenance campaign.

Even though the turbines had only been in operation since 2017, Equinor puts a positive spin on the 4-month maintenance outage, declaring total victory:

“The successful completion of the maintenance campaign on Hywind Scotland is a testament to the collaborative efforts of our teams and partners. As the world’s first floating offshore wind farm, Hywind Scotland has demonstrated the immense potential of floating wind. Through this maintenance campaign, we’ve gained valuable insights that will help us refine maintenance practices and optimise this technology for the future. By sharing our learnings, we aim to contribute to the growth and development of the floating wind industry.”

Some of the folks in Scotland have a different take as evidenced in this video:

Meanwhile, the turbines planned for offshore Central California will also have to be towed to shore for major maintenance. Nearby harbor areas like Morro Bay (pictured below) would be overwhelmed by the large structures and the maintenance and repair operations. Central Coast residents are not enamored with “another attempt to industrialize the coast.” Towing the towers to LA/Long Beach, albeit rather distant from the leases, would seem to be the preferred option for such work.

Looking forward, the first power generation from floating wind turbines on the Central Coast is forecast for 2034. Betters may want to take the over!

In the attached supplement to his comments on BOEM’s financial assurance rule for offshore oil and gas facilities, decommissioning specialist John Smith raises concerns about reliance on cost data submitted by operators. John contrasts operator estimates for platforms in California state waters with estimates provided by independent consultants.

As summarized below and explained in the attachment, the more realistic independent estimates were 2-3 times higher than the operators’ “high end” estimates.

The Fraser Institute’s 2023 Canada-US Energy Sector Survey of senior executives in the upstream oil and gas sector provided data for assessing the competitiveness of US and Canadian jurisdictions. The resulting perception index (below) ranked Wyoming at the top with a score of 100.0 and California at the bottom with a score of 0.0. Perhaps one or more of the respondents have been mired in the California decommissioning quagmire. ☹

John Smith, a decommissioning specialist who retired from BOEM, has published numerous professional papers on the topic. He has kindly shared his comments (below) on the new GAO report.

The Appeal Process is Broken – The GAO should have emphasized this point.  Companies routinely appeal orders to decommission platforms to forestall having to spend money on plugging wells and removing platforms, pipelines and other facilities. The appeal process commonly takes 5 or more years to reolove (e.g., DCOR appeal of BSEE order to decommission Platform Habitat).

Well P&A – BSEE has been negligent in requiring operators to plug and abandon wells no longer useful for operations. I’m shocked BSEE has curtailed or stopped issuing Inc’s for the failure of operators to P&A wells.  That’s a major failure on the part of BSEE management. That may explain why operator performance criteria was proposed to be eliminated for financial assurance.

Failure to Issue Civil Penalties for Well P&A – From GAO Report “BSEE officials explained that their reluctance to pursue civil penalties stems in part from concerns about whether inducing financial harm against an operator is an effective approach to compel decommissioning. They expressed reservations about taking actions—such as issuing civil penalties—that might strain the financial resources of operators to the point of pushing them into bankruptcy.”   This attitude underscores a real problem – an abrogation of regulatory and enforcement responsibility by BSEE. 

POCS Well P&A –  More than 700 wells have been drilled from the 23 California OCS platforms. The GAO report notes that approximately 200 are in the process of being plugged and abandoned – about 50% of those are probably associated with Gail, Grace, Harvest, Hermosa, Hidalgo, where P&A work has largely been completed by Chevron and Freeport McMoRan.  The vast majority of the remaining 500 wells are no longer useful for operations and have been idle for several decades.  Note POCS was never part of the Idle Well and Idle Iron Program, which was exclusive to the GOM. GAO gave POCS BSEE a pass by not highlighting that problem in POCS. It would have been interesting to know how many of the remaining 500 POCS wells are considered no longer useful for operations, and how many of those have been temporarily plugged and abandoned pursuant to regulations.  The GAO report broke that down for the GOM.

Footnote 46 of GAO Report – “Two of the eight platforms due for decommissioning in the Pacific—platforms Hogan and Houchin—have posed serious safety, environmental, and financial risks, including poor safety compliance records, severe corrosion, and ongoing disputes about who will assume decommissioning liabilities for the platforms and their associated wells, according to BSEE officials and documentation. According to BSEE, these platforms are currently being attended, monitored, and maintained as part of an agreement between BSEE, BOEM, Interior’s Office of the Solicitor, and the three predecessor operators pending a decision from the Interior Board of Land Appeals on the predecessors’ appeal. BSEE estimates that approximately $5 million of the estimated costs to decommission 21 orphaned sidetrack wells associated with these platforms are uncovered by financial assurances.”    $5 million divide 21 = $238,000 per well  – extremely conservative cost estimate given age of wells, likely collapsed casing, and downwhole equipment that needs to be removed.  The cost could easily be 3-4 times higher and there is no bonding so the federal government and taxpayers are on the hook for those costs.

Platform Hogan and Houchin Wells – approximately 75 wells were drilled from the platforms.  It would be interesting to know the status of those wells.  How many have been properly temporarily plugged and abandoned with long-term barriers installed to prevent leaks before decommissioning pursuant to OCS regulations?  Are the 21 orphaned wells mentioned above the Signal wells?  What about the other 54 wells?  Have the predecessor lessees agreed they are responsible for plugging and abandoning those wells?  

Platform Habitat – GAO could have noted this is another example of the broken appeal process. It would be interesting to know whether the 21 wells (primarily if not all gas wells) on Habitat have been temporarily abandoned. There are likely to be significant fugitive emission levels at the platform.  Hopefully the APCD is on top of that.  Note – the platform is unmanned and as I previously mentioned a potential catastrophe was avoided several years ago when a fire broke out on the platform.

Hywind Scotland, Equinor

It’s prudent, if not imperative, to tow floating wind turbines to sheltered coastal locations for major maintenance. For that reason, Hywind, the world’s first floating wind farm will be offline for up to 4 months this summer.

Hywind Scotland‘s operator, Norwegian power giant Equinor, says that operational data has indicated that its wind turbines need work. The pilot project has been in operation since 2017.

The five Siemens Gamesa turbines will be towed to Norway this summer. An Equinor spokesperson said, “This is the first such operation for a floating farm, and the safest method to do this is to tow the turbines to shore and execute the operations in sheltered conditions.”

Published data indicate that Hywind has been the UK’s best performing offshore wind farm. Performance data for Hywind, and a chart illustrating the capacity factors since commissioning, are posted below. The 2024 capacity factor will, of course, be substantially reduced as a result of the essential offsite maintenance.

The first US floating turbines are expected to be at these California offshore leases, and Hywind operator Equinor is one of the lessees:

Given the financial challenges facing the offshore wind industry, the still emerging technology, and the risks inherent in California offshore development, the amounts bid on these leases only 13 months ago are stunning.

Some Central Coast residents are not enamoured with “another attempt to industrialize the coast.” Although the turbines will be >20 miles offshore, they will have to be towed to shore for major maintenance. For the Central California leases, nearby harbor areas like Morro Bay (pictured below) would be overwhelmed by the large structures and the maintenance and repair operations. Towing the towers to LA/Long Beach, albeit rather distant from the leases, would seem to be the preferred option for such work.

Ironically, a report for BOEM, points to synergies between the offshore wind industry and oil and gas decommissioning industry. Such synergies will only be possible if longstanding oil and gas decommissioning obstacles are satisfactorily addressed and the offshore wind projects proceed as planned.

Which will come first – platform decommissioning or wind turbine commissioning? For those young enough to find out, what is the over-under for the years until (1) half of those platforms are decommissioned, and (2) half of the wind turbines commissioned? Any number <10 is unrealistic for either.

Montecito Journal: Oil Platforms’ Removal?:Reefing the Superior Environmental Option

On December 7, 2023, the Bureau of Safety and Environmental Enforcement (BSEE) issued a Record of Decision (ROD) recommending the full removal of California’s 23 offshore oil platforms in federal waters, following a Programmatic Environmental Impact Statement (PEIS) conducted to assess decommissioning options for platforms, pipelines, and other related infrastructure. However, upon close review, the PEIS and ROD appear to have reached misguided and detrimental conclusions due to critical oversights in their analyses.

Asher Radziner, Montecito Journal

The author aptly summarizes the flaws in the PEIS and the BSEE decision document. Very good analysis.

Exxon has joined Chevron in announcing Q4 write downs associated with California operations. In Exxon’s case, the estimated $2.4 billion to $2.6 billion impairment is the result of their troubled Santa Ynez unit facilities in the Santa Barbara Channel where the unit’s 500+ million barrels of reserves are unlikely to ever be produced.

The Santa Ynez saga is really quite remarkable. More here and here.

On January 2, 2024, Chevron Corporation announced that for fourth quarter 2023, the Company will be impairing a portion of its U.S. upstream assets, primarily in California, due to continuing regulatory challenges in the state that have resulted in lower anticipated future investment levels in its business plans. The Company expects to continue operating the impacted assets for many years to come. In addition, the Company will be recognizing a loss related to abandonment and decommissioning obligations from previously sold oil and gas production assets in the U.S. Gulf of Mexico, as companies that purchased these assets have filed for protection under Chapter 11 of the U.S. Bankruptcy Code, and we believe it is now probable and estimable that a portion of these obligations will revert to the Company. We expect to undertake the decommissioning activities on these assets over the next decade.

On Monday, we will be posting comments on the proposed bankruptcy sale of Cox’s GoM assets and the related safety and decommissioning concerns.
