The Town of Nantucket’s attorney, Greg Werkheiser of Cultural Heritage Partners, told The Light last month that “it’s taken far too long” to get a final report on the blade failure.
Member companies, which include major players such as Ørsted, Equinor, Vattenfall, RWE, and CIP, report quarterly data on accidents, near-misses, hazardous observations, and equipment damage. As is the case with most industry reporting schemes, anonymity is prioritized over transparency.
Sørensen asserts that the G+ wind industry data are incomplete: ”It shows that what is reported under the guidelines has gone down, and also that there is a cut off on what is being reported that does not include the full value chain on the industry.” He notes that a contractor to Northland Power from Canada, a member of G+, was involved in a 2024 workplace accident in Taiwan that resulted in three fatalities. (It’s also noteworthy that Equinor’s 2024 Empire Wind fatality was not included.)
Sørensen: ”There have been no significant improvements in the last 10 years. Safety in offshore wind is neither getting worse nor better. There are no signs of that.”
”I’m speaking up because we owe people the truth. If we’re not honest about the actual safety conditions in offshore wind, we can’t change them. Misinformation about workplace safety creates a dangerous illusion that everything is “under control”, while too many people are getting hurt. But when we dare to speak about reality as it is, we create the foundation for a safer, faster, and truly sustainable energy transition,” Sørensen says.
”And then it becomes difficult to learn if you have to wait for something to go through 57 gates and down past legal,” he says. (Sound familiar?)

We can scream all we want (with some justification) about the California Coastal Commission, Santa Barbara County, and intractable environmental organizations, but the Santa Ynez Unit would still be producing today were it not for an ugly, preventable pipeline spill.
At approximately 10:55 a.m. Pacific Daylight Time (PDT) on May 19, 2015, the Plains Pipeline, LP (Plains), Line 901 pipeline in Santa Barbara County, CA, ruptured, resulting in the release of approximately 2,934 barrels (bbl) of heavy crude oil. An estimated 500 bbl of crude oil entered the Pacific Ocean.
1) Ineffective protection against external corrosion of the pipeline The condition of the pipeline’s coating and insulation system fostered an environment that led to the external corrosion. The pipeline’s cathodic protection (CP) system was not effective in preventing corrosion from occurring beneath the pipeline’s coating/insulation system. 2) Failure by Plains to detect and mitigate the corrosion The in-line inspection (ILI) tool and subsequent analysis of ILI data did not characterize the extent and depth of the external corrosion accurately. 3) Lack of timely detection of and response to the rupture The pipeline supervisory control and data acquisition (SCADA) system did not have safety-related alarms established at values sufficient to alert the control room staff to the release at this location. Control room staff did not detect the abnormal conditions in regards to the release as they occurred. This resulted in a delayed shutdown of the pipeline. The pipeline controller restarted the Line 901 pipeline after the release occurred. The pipeline’s leak detection system lacked instrumentation and associated calculations to monitor line pack (the total volume of liquid present in a pipeline section) along all portions of the pipeline when it was operating or shut down. Control room staff training lacked formalized and succinct requirements, including emergency shutdown and leak detection system functions such as alarms.
Plains Pipeline was the responsible party, but that doesn’t absolve the companies that were dependent on Plains to transport their production. Given the organized opposition that emerged following the Santa Barbara blowout in 1969 (the result of a reckless well plan), the integrity of that pipeline was critical to their business strategy and they should have exercised some oversight.
Offshore disasters have had enormous consequences for the oil and gas industry in terms of lost opportunities. Think about this: prior to the Macondo blowout, the Obama administration had proposed an oil and gas lease sale in the Atlantic and the Florida Senate was holding hearings about leasing in Florida State waters. Such lease sales are now completely out of the question.
Regulations and standards are not enough. We need open discussion about incidents, large and small, and a willingness to be critical of the responsible parties.
The COS has been effective in strengthening corporate Safety and Environmental Management Systems, influencing the industry’s safety culture, and sharing best practices and lessons learned. These are important accomplishments.
The COS has fallen short in gathering the data needed to assess the offshore industry’s safety performance. As is the case with most voluntary reporting programs, data completeness and accuracy issues limit the significance of COS performance reviews.
The COS uses accepted performance indicators and a logical classification scheme.
COS reports that their members accounted for 78% of OCS oil and gas activity in 2024. This is accurate when cross-checked with BSEE hours worked data. However, the % of hours worked is not a good measure of the % of incidents reported in any category.
Only two drilling contractors – Helmerich & Payne and Valaris – are members. Major contractors like Noble, Transocean, and Seadrill are not members. Their incidents will thus not be reported if they are not working for a COS member.
No production contractors are COS members. These companies conduct most of the platform operations on the shelf, where many of the lease operators are not COS members.
Pacific and Alaska Region operators do not participate.
Looking only at fatalities (table below), the most important and easily verified incident category, there are troubling omissions:
COS reports no 2024 fatalities when in fact there was a fatality during an operation for a COS member.
COS reports no 2022 fatalities when there were actually five. A workover incident took the life of one worker, and four died in a helideck crash on an OCS platform. In both cases, the facility operator was a non-member company.
COS records one 2021 fatality, but fails to include a 2021 Fieldwood fatality. There were also6 “non-occupational” fatalities on OCS facilities in 2021, as classified by BSEE. Given the importance of worker health (the H in HSE), such a high number of non-occupational fatalities should be of interest industry-wide.
The COS report includes only two of the six 2020 fatalities, 2 of which were classified by BSEE as non-occupational.
The bottom line is that COS accounted for only 3 of 12 (25%) occupational fatalities during the 2020-24 period. There were at least 20 fatalities if you include the non-occupational incidents.

The offshore industry is only as good as its worst performer, so complete participation is essential. Voluntary reporting is seldom complete reporting, because some companies are more concerned about confidentiality than completeness and information sharing.
For industry reporting programs to be comprehensive and credible:
The entity receiving the reports and managing the data must be independent and not affiliated with an industry advocacy organization.
All operating companies must participate and complete reporting must be required. This can be accomplished contractually. If necessary, the regulator can require participation (either as a separate regulation or as a SEMS element).
Company incident submittals should be audited by the independent entity.
Fees should be solely for the purpose of supporting the independent reporting system.
For SP1 and SP2 incidents (per the COS classification scheme), the names of the responsible companies should be included in the performance reports. The current COS system prioritizes confidentiality over accountabiity and information sharing.
Difficult operating conditions, high costs, and relatively modest oil price projections are no doubt factors contributing to the absence of bids. Energy NL has also pointed to the “complex, inconsistent and burdensome regulatory system” as a contributing factor.
Newfoundland’s newly elected Premier, Tony Wakeham, has said his Progressive Conservative Government will advocate for the cancellation of the emissions cap as it is a cap on production. He also supports incentives for offshore oil and gas projects such as an investment tax credit or the former Petroleum Incentive Program and indicated he would work with Energy NL to review incentives that could be implemented provincially.
The C-NLOER is committed to “review its land tenure system in collaboration with governments and others, to identify opportunities to enhance competitiveness in the Canada-Newfoundland and Labrador Offshore Area.”
Plymouth MA wind turbine that lost a blade. (Stuart Cahill/Boston Herald)
Friday’s turbine blade failure in Plymouth MA is perhaps getting added attention given its proximity to the 7/13/2024 Vineyard Wind blade failure offshore Nantucket. The Plymouth blade landed in a nearby cranberry bog (video and picture below).
Per the MV Times, the turbines for the Plymouth project were manufactured by Gamesa, which is now part of Siemens Gamesa. Both the South Fork Wind and Revolution Wind projects off the coast of the Martha’s Vineyard are being developed by Ørsted using turbines from Siemens Gamesa. Coastal Virginia Offshore Wind, the largest offshore wind project in the United States, is also being developed with Siemens Gamesa turbines. This is not to imply a higher degree of risk for those turbines. Vineyard Wind, where the only US offshore failure has occurred to date, is using GE Vernova turbines.
Unfortunately, turbine blade failures are much too common. Last October, Lars Herbst reported, based on a Wind Power article, that “with an estimated 700,000 blades in operation globally, there are, on average, 3,800incidents of blade failure each year.” Lars noted that the annual blade failure rate of about 0.5% translates to 1.5% of all operating wind turbines experiencing a blade failure every year, a remarkably high failure frequency.
Scotland Against Spin data indicate that blade failure is the second most common accident type in the wind industry, and the most common cause of accidents at operational wind turbine sites. SAS reports further that pieces of blade are documented as travelling up to one mile, and have gone through the roofs and walls of nearby buildings.
Lastly, we are still awaiting BSEE’s report on the Vineyard Wind failures so we can better understand what happened and why.
JL Daeschler brought the report on the Titan submersible tragedy to my attention. In June 2023, five died when the Titan dove to the Titanic wreckage in the North Atlantic (map below).
The full NTSB report has now been issued and is attached.
The NTSB found that OceanGate’s engineering process for the Titan was inadequate and resulted in the construction of a carbon fiber composite pressure vessel that contained multiple anomalies and failed to meet necessary strength and durability requirements. Because OceanGate did not adequately test the Titan, the company was unaware of the pressure vessel’s actual strength and durability, which was likely much lower than their target, as well as the implications of how certain operational changes, including storage condition and towing, could impact the integrity of the pressure vessel and overall safety of the vessel. Additionally, OceanGate’s analysis of Titan pressure vessel real-time monitoring data was flawed, so the company was unaware that the Titan was damaged and needed to be immediately removed from service after dive 80.
As is the case with most NTSB reports, the technical analysis and findings are very sound. However, it would be helpful if the NTSB also considered the organizational factors that contributed to the engineering process failures, testing inadequacies, and data analysis flaws. Was there pressure to accelerate the mission? Budget crunch? Training deficiencies? Oversight issues? This type of information can help improve management systems and prevent accidents throughout the marine industry and beyond.
The SAS data indicate that the number of wind turbine incidents has risen sharply in recent years (see chart below). The increased number of turbines worldwide, and perhaps better news coverage of incidents, presumably contributed to the sharp increase. Nonetheless, the growing number of incidents is disconcerting, as is the absence of industry and government summaries and reports.
SAS acknowledges that their list, which is dependent on publicly available reports, is merely the “tip of the iceberg.” For example, the list does not include the June 2, 2025, Empire Wind project fatality.
The SAS list does capture the 2018 collapse of the Russell Peterson liftboat, which was collecting data offshore Delaware for a wind project. One worker died and another was seriously endangered. The Coast Guard never issued a report on this tragic incident. Serious questions remain about the positioning of a liftboat in the Mid-Atlantic for several months beginning in March when major storms are likely, the liftboat’s failure mechanisms, the operator’s authority to be conducting this research, and the actions that were taken in preparation for storm conditions.
