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.
John Borne was an exceptional engineer and offshore safety leader in our OCS oil and gas program during the US Geological Survey (Conservation Div.) and Minerals Management Service (MMS) eras.
Some thoughts on John’s leadership followed by tributes from distinguished colleagues:
John’s Houma District office was a model for the rest of the OCS program. Houma was the program’s busiest district in terms of operational activity, and the most effective in meeting permitting, inspection, and investigation targets.
The few serious accidents that occurred in the District were carefully investigated and the findings were shared in a timely manner with the goal of preventing their recurrence. If John signed a report, you knew it was complete and accurate.
John was knowledgeable about the complex offshore oil and gas operations he regulated, and was an outstanding teacher and mentor.
John treated all companies the same from the super-majors to the small independents – no biases, no favors, and no ethics issues.
John expected companies to fully comply with the regulations. Any departures had to be clearly in the best interest of safety and the environment.
From Ken Arnold (ex-Shell engr, Paragon Engineering President, NAE): As part of the Shell Training program in 1964 I was assigned to trail John in East Bay for a week. One night I was talking to another trainee on a logging barge tied up to a posted barge rig in SP Blk 24. John was also on the barge. Without warning the barge started pulling away from the rig. The three of us jumped from the barge to the rig but I slipped and fell in the canal. I don’t think I was in the water long enough to get wet, when John and a rig hand fished me out. Unfortunately my glasses fell off and were in the mud. John got a scissors device and retrieved my glasses in a matter of minutes.
I greatly appreciated my week with John. What he took the time to teach me about field work was critical to my subsequent successful career in Shell and in Paragon. He was a gentleman and a first class teacher. I was lucky to have known him.
Jodie Connor (founder and retired President of J. Connor Consulting): John was an excellent representative of the MMS, always fair in his decision-making and approvals. I endearingly called him “By the Book Borne”. He enforced the regulations as they were written, which was fair to all operators. Always kind and willing to explain MMS policies.
Lars Herbst (retired MMS/BSEE Regional Director, Gulf of Mexico): What a legend at MMS! A testament to his leadership are the number of Regional leaders that came out of Houma District. Just to name a few: Mike Saucier, Bryan Domangue, Troy Trosclair, and even Jack Leezy! That work ethic that John instilled has continued even to the next generation of leadership! I was fortunate that John let me act as Drilling Engineer when Saucier went hunting each December. My career at MMS was never the same after that opportunity!
Jack Leezy: (President, Avenger Consulting, retired MMS): John served in the Marine Corp during the Korean war. Upon discharge from the Marine Corp John attend the University of Lafayette and earned a BS degree in Petroleum Engineering. John started his oilfield career when he went to work for Shell Oil in 1960 until 1970 as a Petroleum Engineer.
John joined U.S.G.S. In 1970 as a Petroleum Engineer in the Lafayette District. John accepted a promotion in 1972 in the Regional office and was selected as the first District Supervisor in the newly formed Houma District office in October1974. John remained as the District Supervisor until his retirement in 1995. John was instrumental in developing Bureau policies of which some are still in place as of today. John served on countless MMS and industry committees alike during his career. John was looked upon as professional and highly respected by MMS and industry alike. He performed is duties in such a way that even if you may not have liked his decision, you respected it. John’s demeanor never changed as he never lost his composure and worked evenly though all the trials and tribulations during his career at MMS. John even won MMS’s Engineer of the Year award. I owe a lot to John in helping me form my career at MMS as I tried to handle my supervisory duties in the same manner in which John did.
RIP John. You were a superstar! As an engineer, regulator, leader, teacher, and colleague, no one did it better!
Chevron slide: Advances in seismic imaging help characterize deepwater development opportunities
A new JPT article features comments from BOE contributor Lars Herbst on advances in HPHT technology, control systems, sensors and transmitters, and automation that are facilitating the next era of deepwater development.
Well capping technology, which provides a tertiary well control capability, is an essential element of post-Macondo exploration and development. Lars points to the importance of BSEE’s unannounced drill program to verify that capping stacks can be transported and installed in a timely manner. Chevron expresses pride in leading a team that deployed and installed a capping stack in 6,200 feet of water in a drill monitored by BSEE. During that drill, a remotely operated vehicle (ROV) closed 10 valves to shut in a simulated well.
Exxon’s Jayme Meier aptly characterizes the challenge and excitement of deepwater development:
“You are floating on a surface, and you have to be able to pinpoint exactly where you’re going to land subsea hardware, exactly where you’re going to moor an FPSO and hit target boxes that are a few feet by a few feet, and they’re 6,000 ft below you,” she said. “It is the most exciting thing that I’ve ever been involved in. And it involves technology, technical know-how, and an ability to really plan the base plan and the contingency plan.”
Advances in deepwater technology are indeed impressive, but continuous improvement must always be the objective. In that regard, Lars rightfully emphasizes the importance of sustaining research through the industry’s up and down cycles.
Lars Herbst noted another endangered whale sighting by the US Coast Guard. Unlike their erroneous Rice’s whale report in September (still waiting for their mea culpa), the Coast Guard has gotten this one right. The 25,000 ton Whale is pictured above.
Whale’s species is indeed endangered with the most serious threats coming from a faraway place on the Potomac River. The “newborn” Whale is one of only 15 of its species in the Gulf of Mexico. The entire platformus deepis genus numbers only 59, but their importance to society is enormous (read more).
Perhaps the wise people who control our offshore lands will do more to encourage and support these floating behemoths. Unfortunately, their 5 year management plan is not encouraging in that regard.
Tennessee Twist:TC Energy’s $29.3 million investment in a RNG (renewable natural gas) production facility near the Jack Daniel’s Distillery will see the Canadian operator producing RNG with a carbon-intensity score that is 50% lower than traditional natural gas, saving up to 16,000 tonnes of CO2e per year, according to the company.
“This investment is our first in the production of renewable natural gas,” said Corey Hessen, TC Energy executive vice president and president, power & Energy solutions. “The production of RNG onsite at the Jack Daniel’s Distillery offers TC Energy one more opportunity to meet the challenge of growing energy needs and reducing emissions while providing customers with access to an affordable, reliable, source of energy.”
After an amazing 38 year career with MMS and BSEE, Lars Herbst has announced that he will retire at the end of 2021. Lars had important technical and managerial roles in the development of the deepwater Gulf of Mexico, the response to major hurricanes including Ivan, Katrina, and Rita, controlling the Macondo blowout and addressing the related regulatory issues, and the offshore industry’s response to the COVID-19. Lars was an active participant in the International Regulator’s Forum and is recognized worldwide for his operational and regulatory expertise. Best wishes to Lars as he transitions to the next phase of his life.
