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.

Vineyard Wind project

BOEM is charged with protecting the public from financial risks associated with the decommissioning of offshore facilities. Previous posts have addressed oil and gas facility decommissioning issues and proposed revisions to BOEM’s financial assurance regulations for those operations.

Recent disclosures indicate that BOEM, which very publicly promotes the offshore wind projects that it regulates, has waived a fundamental financial assurance requirement at the request of Vineyard Wind (approval letter attached). Given its broad applicability, this precedential waiver could have the effect of revising a significant provision of the offshore wind decommissioning regulations without public review and comment.

The issue is the “pay as you build” financial assurance requirement at 30 CFR § 585.516, which was waived by BOEM. This requirement, which is intended to project the public from decommissioning liability, is fair and reasonable given that wind developers must only provide financial assurance “in accordance with the number of facilities installed or being installed.” Companies that don’t have sufficient financial strength to comply with this requirement should not be installing and operating offshore wind turbines.

Vineyard Wind was either unable or unwilling to comply with the requirement. They instead requested to defer providing the full amount of the required financial assurance until year 15 of actual operations. The waiver changes “provide assurance when you install” to provide assurance 15 years after installation if everything goes as planned (hoped?).

After their waiver request was denied in 2017, Vineyard Wind resubmitted the request in 2021 seeking a favorable decision from an administration concerned that project cancellation or delay might tarnish the program that they were enthusiastically promoting.

BOEM (as directed from above?) granted the waiver, citing the general departure authority at 30 CFR § 585.103. However, that authority is intended for special situations, not for broadly applicable waivers that have the effect of revising the regulations without the public review required by the Administrative Procedures Act and Executive Orders 12866 and 13563.

There are no criteria in the Vineyard Wind waiver approval that could not apply to other wind developers. Vineyard Wind has simply committed to the same “risk-reduction factors” that apply to all offshore wind projects: damage insurance, the “use of proven turbine technology,” and long-term power purchase agreements. How could BOEM deny the same request from other companies?

It’s noteworthy that the regulations specific to financial assurance at 30 CFR § 585.516 provide no criteria for waiving the assurance requirements; nor do the regulations provide for the 15-year payment plan approved by BOEM. Given the precedential nature of the BOEM action and its enormous financial implications, a revision to the decommissioning regulations that provides criteria for such payment schemes should be promulgating before any similar departures are approved.

In light of the waiver, the public will likely incur substantial costs if Vineyard Wind fails, walks away, doesn’t fully fund their decommissioning account in a timely manner, or seeks new concessions after some or all of the 62 turbines have been installed.

Given the decommissioning obligations, what company would want to step in and assume responsibility for a failing project 10-15 years from now? What happens if Vineyard Wind’s project revenues don’t meet expectations and contributions to their decommissioning account are insufficient or used improperly? More concessions? We’ve seen this dance before.

Whether the project is for oil, gas, or wind energy, protecting the public from decommissioning liabilities should always be prioritized over facilitating development.

Polymetallic nodules contain critical metals (TMC images)

“the committee directs the Assistant Secretary of Defense for Industrial Base Policy shall, by March 1, 2024, submit a report to the House Armed Services Committee assessing the processing of seabed resources of polymetallic nodules domestically. The report shall include, at a minimum, the following:
(1) a review of current resources and controlling parties in securing seabed resources of polymetallic nodules;
(2) an assessment of current domestic deep-sea mining and material processing capabilities; and
(3) a roadmap recommending how the United States can have the ability to source and/or process critical minerals in innovative arenas, such as deep-sea mining, to decrease reliance on sources from foreign adversaries and bolster domestic competencies.

The above map shows the offshore carbon disposal leases acquired by Repsol from the Texas General Land Office (GLO) and the adjacent Federal tracts Repsol bid on at OCS Lease Sale 261. There should be absolutely no confusion regarding Repsol intentions at Sale 261. They plan to develop a large CO2 disposal hub offshore Corpus Christi and bid improperly at an OCS oil and gas lease sale to support that objective.

Perhaps blinded by visions of “a stream of U.S. government grants, followed by generous tax credits for every ton of carbon stored,” Repsol (Sale 261) and Exxon (Sales 257 and 259) have made a mockery of the OCS leasing process and the regulations that guide it. The Repsol bids should be promptly rejected.

So what about the Exxon nearshore Texas leases that have already been issued? Given that Exxon misled the Federal government and improperly acquired carbon disposal leases at an oil and gas lease sale, those bids should be cancelled pursuant to 30 CFR § 556.1102:

(c) BOEM may cancel your lease if it determines that the lease was obtained by fraud or misrepresentation. You will have notice and an opportunity to be heard before BOEM cancels your lease.

While Exxon’s oil production increases in the Permian Basin and offshore Guyana are impressive, is it not hypocritical for Exxon and other major producers to capitalize on the capture and disposal of emissions associated with the consumption of their products? Is it not just a bit unsavory for oil companies to cash in on (and virtue signal about) carbon collection and disposal at the public’s expense? Perhaps companies that believe oil and gas production is harmful to society should be reducing production rather than engaging in enterprises intended to sustain it.

As we approach the 55th anniversary of the Santa Barbara blowout (more to follow), pioneering subsea engineer JL Daeschler reminds us of a lesser known, but very serious, drilling blowout that occurred the same year offshore Northern Australia.

As is the case with most historic incidents, the lessons learned are still pertinent today and should be studied by those involved with well operations. Training sessions should consider what went wrong then, how technology and practices have changed since, how similar incidents could still occur, and innovations and improved practices that could further mitigate well control risks.

While well control technology and procedures are much improved, the fundamental issues discussed in the attached video remain the same. Well control must always be considered a work in progress with continuous improvement being the objective.

(The Sedco 135G semisubmersible that drilled this well is of the same design as the Sedco 135B rig that sank offshore Borneo in 1965.)

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.

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

Sale 261: single bid tracts in blue, multi-bid tracts in red (2), green (3), and purple (5)

The interest of the majors and most independents has shifted entirely to deepwater prospects, as evidenced by the above graphic and sale data. Nonetheless, a few resourceful companies continue to find value in the shallow waters of the continental shelf.

There’s an art to finding oil—particularly in the Gulf of Mexico. After decades of drilling, this world-class basin still holds vast potential for those skilled enough to unlock it. Arena energy is applying expert insight and advanced technology to identify new Gulf of Mexico oil and gas exploration opportunities. This is the art of oil finding in the 21st century.

Arena Energy

Arena Energy, a successful shelf operator for a quarter of a century, was the leading shelf bidder with 6 high bids. In 2023 Arena was once again the most active shelf driller with 20 well starts. They claim a 94% drilling success rate. Arena currently operates 123 platforms and is the GoM’s 7th ranked natural gas producer and the 11th ranked oil producer.

Cantium, another leading shelf operator, was the high bidder on 4 tracts. Cantium drilled 10 wells in 2023 and currently operates 86 platforms. Cantium claims to maintain “the highest level of operational safety and regulatory compliance by maximizing efficiencies and empowering employees,” and publicly available compliance data bear that out. Cantium was a BOE Honor Roll company for 2022, and a preliminary look at the data indicates that their 2023 performance was also excellent. Cantium is ranked 18th in both oil and natural gas production.

Byron Energy, which is headquartered in Australia, is the only international company investing in the GoM shelf. Byron was the high bidder on 2 tracts and currently operates 2 platforms. The company drilled 3 wells in 2023. Byron intends to continue focusing on the shallow waters of the Gulf. 

Thoughts on the attributes of a successful shelf operator:

  • Bid alone and conduct operations independently to facilitate efficiency and timely decisions.
  • Lean and flat organizational structure for optimal communication and effective project management.
  • Skilled staff and state-of-the art exploration technology.
  • Outstanding contractor selection and oversight.
  • Safety, environmental, and compliance leadership, absent which your company won’t be around for long.
  • Think small. Gleaning old fields and producing modest new discoveries can be profitable!
  • Control growth and debt. Busts follow booms and highly leveraged companies are the most vulnerable.
  • Study the successful shelf operators and the failures. What did they do right and wrong?
