When Norwegian billionaire Ekonor was awarded a multi-billion dollar contract to build wind turbines on Long Island’s New York coast in 2018, an important part of the award was the use of massive concrete foundations.
That choice will result in hundreds of jobs in the Albanian region and will provide significant environmental benefits, “according to the State of the Year.”
But Ekurnoor fully promises to use those “gravity-based structures” for the project or for another large wind farm near it. His recent construction and operational plan details the options in detail: using huge monopolies from a submarine.
In the same report, Ekonor said that gravity-based structures “are more vulnerable to weak horizontal layers under local forces than under basics.” And he says that because of “design challenges”, concrete foundations have already been “taken into consideration” for use in the coastal distribution as part of the project.
Ecuador’s spokesman said the concrete foundations, which were used as heavy backyard umbrellas to keep the turbines upright during difficult beach conditions, were still on the cards.
“We aim to use the best foundations for our project: from an environmental, operational, construction and long-term business perspective,” said spokeswoman Lauren Shane. Computes the construction plan “Gravity-Based Structure (GBS) and Monopoly Basic Types. As we move toward the completion of the design of the project, we will continue to evaluate the feasibility of both types with a number of other key elements. ”
The use of stacked monopoly has one significant advantage over gravity-based concrete foundations: cost. The Norwegian parent of Ecuador may have had some repercussions after recently reported that US oil and gas operations suffered losses of $ 21.5 billion between 2007 and 2019. Significantly reduced or eliminated.
In a statement issued last week, the New York State Energy Research and Development Authority, which has awarded contracts to 18 other projects, said it had many options for completing the project.
»NYSERDA Ekornoor expects the best choices to implement the most efficient, cost-effective and safer construction and operation plan for marine life, said Kate Mለርller, NYSERDA Vice President of Marketing, in a written response.
He added: “It has always been understood that based on geophysical, geotechnical discoveries and other technical surface and technological characteristics, certain bases will not be able to use gravity-based foundations, so alternatives may be considered.”
And Mለርller said that Einor’s “pre-engineering work is a continuum and the current public licensing approach reflects a framework of a design envelope with a variety of options, taking into account such circumstances with the Bureau of Ocean Energy Management.”
Equinor said it would not reduce other financial obligations imposed by the company in order to operate all-terrain turbines. “Ecuador has pledged $ 792 million for wind farms in the state, including obligations on domestic expenditure and economic development obligations,” he said.
Asked if the region is considering the impact of piracy on whales and other marine life, Mለርller said the agency is “committed to working with overseas industry, industry experts and stakeholders to ensure that New York’s coastal wind projects are cost-effective and responsible.” Built for the benefit of New York residents and the environment, it is taking advantage of a strong reduction plan throughout.
A.D. In 2018, he will be joined by former governor Andrew M. Kumo and former US Vice President Al Gore. In September, 2019 College, gravity-based foundations were the only option discussed.
Under the heading, “Let’s Share the Future of New York Together”, the presentation lists only the concrete foundations “produced in the capital,” and provides artists’ conceptual drawings of the ships towed to Hudson. The presentation promised “thousands of jobs” when creating a “concrete foundations manufacturing center”.
In a recent construction and operation plan presented by the Federal Ocean Energy Management Bureau, Ecorin excluded gravity-based concrete foundations for use with a submarine station, citing “operational challenges” related to boat landings and landings. Cruise ship. “
Regarding the turbines themselves, the report states that the concrete foundation “requires the top layers of soil to be strong enough to withstand heavy loads. It may require floor upgrades to distribute such loads and stabilize the installation. ” That means placing a separate layer of gravel under each concrete foundation, scraping “loose sand to replace it with rocks or skirts,” the report said.
The report states that driving the turbines eliminates those problems, and the Empire has already studied the “sliding” of the sea. He realized that driving a 246-foot monopoly would require 3,506 piles of hammers and 626 mines.
The document states that ground-mounted monopolies and stacked “jackets” are “well-designed and well-structured in solid structures in general with well-adjusted stacking depth, pixel diameter and pile wall thickness.”
In the two primary options, Monopoly and Concrete, as well as the base-jacket foundations, exploration continues.
A.D. A 2019 study of gravity-based foundations in the Journal of Marine Sciences and Engineering found that the structures had a “high load capacity” when used in the offshore oil and gas industry.
Negatives?
“Not yet widely accepted in the wind industry”, it must be stored in soil with “certain geotechnical characteristics” required for soil preparation, and has a large impact on the sea. Monopoly boasts comparable “simplicity of structure,” as well as low cost, the authors found.
