Wind Turbines Slow Down Hurricane Winds
Off the New York coastline would be a perfect place for an array of wind turbines, according to a Stanford professor. It would not only offer clean energy to the Big Apple but it would protect it the next time a Superstorm Sandy comes calling.
“If you have a large enough array of wind turbines, you can prevent the wind speeds [of a hurricane] from ever getting up to the destructive wind speeds,” said Mark Jacobson, a professor of civil and environmental engineering at Stanford University.
Computer models demonstrated that offshore wind turbines reduce peak wind speeds in hurricanes by up to 92 mph and decrease storm surge by up to 79 percent, said Jacobson, who worked on the study with University of Delaware researchers Cristina Archer and Willett Kempton.
“The additional benefits are there is zero cost unlike seawalls, which would cost about $30 billion,” he said, noting that the wind turbines “generate electricity so they pay for themselves.”
The researchers studied three hurricanes, Sandy and Isaac, which struck New York and New Orleans, respectively, in 2012; and Katrina, which slammed into New Orleans in 2005. Generally, 70 percent of damage is caused by storm surge, with wind causing the remaining 30 percent, he said.
That’s why onshore wind farms would not be as effective, he said. While they would reduce the wind speed, they wouldn’t impact storm surge.
In 2013, one of the “most inactive” Atlantic hurricane seasons on record, insured losses totaled $920 million, according to Guy Carpenter, which relied on information from the Mexican Association of Insurance Institutions. The most noteworthy events were Hurricane Ingrid in the Atlantic and Tropical Storm Manuel in the Pacific, which displaced thousands as they caused excessive rainfall, flooding and mudslides.
According to the Insurance Information Institute, Katrina was the costliest hurricane in insurance history, at $48.7 billion, followed by Andrew in 1992 at $25.6 billion and Sandy at $18.8 billion. Economic losses, of course, were much higher.
Wind turbines, which can withstand speeds of up to 112 mph, dissipate the hurricane winds from the outside-in, according to Jacobson’s study. First, they slow down the outer rotation winds, which feeds back to decrease wave height. That reduces the movement of air toward the center of the hurricane, and increases the central pressure, which in turn slows the winds of the entire hurricane and dissipates it faster.
The benefit would occur whether the turbines were immediately upstream of a city, or along an expanse of coastline. It could take anywhere from tens of thousands to hundreds of thousands of wind turbines off the coast to offer sufficient hurricane protection.
At present, there are no wind farms off the U.S. coastline, although 18 have been proposed for off the East Coast. Proposals have also been made for off the West Coast and the Great Lakes. There are 25 operational wind farms off the coast of Europe.
“Overall,” Jacobson and his colleagues concluded in the study, “we find here that large arrays of electricity-generating offshore wind turbines may diminish hurricane risk cost-effectively while reducing air pollution and global warming, and providing local or regionally sourced energy supply.”
The Truth About The Keystone Pipeline
Did you know that the Keystone Pipeline is actually in operation?
Most people don’t.
But then again, most people believe that TRIA has actually covered terror events — but that will be a different article.
Maybe we should start with the facts:
- Phase I of the pipeline runs from Hardesty, Alberta, to Steele City, Nebraska (2147 miles), then on to a refinery in Wood River, Illinois. This was finished in 2010.
- Phase II runs 300 miles from Steele City to storage facilities in Oklahoma. This was finished in 2011.
- Phase III is from Oklahoma to Port Arthur, Texas, where it finished in 2014 with a lateral pipeline connected to refineries at Houston, Texas, to be finished in mid-2015.
So what is it that we keep hearing about? Well that would be Phase IV of the pipeline project. This would start in the same place in Canada, go to the same place in Nebraska, but be wider and have a shorter route. It is this phase that has been the focus of all the discussion, for what seems like forever.
Those who are opposed to the pipeline say, “It’s BAD. It’s bad for the climate, for health, for the environment, for the economy … just BAD.” Those who are for the pipeline say it will create 40,000 jobs, albeit temporary. (But aren’t all construction jobs temporary anyway?) It is also built without government financing. It helps our neighbors to the North, who have approved the project, and helps our economy.
In the United States, we have made it a political question. Congress has approved it, the President has vetoed it, but as the great philosopher Yogi Berra said: “It ain’t over ’til it’s over.”
Only in dreams can we live risk free, so we manage the risks to the best of the industry’s ability.
As for the alternatives, nothing really provides a consensus of agreement. For example, move it by rail. This can and has caused problems. In July of 2013, a parked train of crude oil came loose, rolled down a hill and exploded in a ball of fire in the town of Lac-Megantic in Quebec. The inferno claimed 47 people and the town was practically destroyed. Groups opposed to moving crude by rail commonly refer to the trains as “bomb trains.”
How about by water? In March of 2014, a barge carrying 924,000 gallons of crude oil collided with a ship in Galveston Bay, spilling 170,000 gallons along a route heavily travelled by birds during their seasonal migration.
Ok, let’s move it by truck … well, you get the point.
As a nation, we are now energy independent — something we have talked about since 1973. But we need to move the product from where it is, to where it is needed. We need to do it as safely as possible, human life is sacrosanct and our precious environment needs to be protected.
Only in dreams can we live risk free, so we manage the risks to the best of the industry’s ability. We insure them, we regulate them. What we can’t do is to say “no” to everything.
Let’s finish the pipeline.
Making the Marine Industry SAFE
When it comes to marine based businesses there is no one-size-fits-all safety approach. The challenges faced by operators are much more complex than land based businesses.
The most successful marine operators understand that success is dependent on developing custom safety programs and then continually monitoring, training and adapting.
After all, it’s not just dollars at stake but the lives of dedicated crew and employees.
The LIU SAFE Program: Flexible, Pragmatic and Results Driven
Given these high stakes, LIU Marine is launching a new initiative to help clients proactively identify and address potential safety risks. The LIU SAFE Program is offered to clients as a value added service.
“The LIU SAFE program goes beyond traditional loss control. Using specialized risk assessment tools, our risk engineers function as consultants who gather and analyze information to identify potential opportunities for improvement. We then make recommendations customized for the client’s business but that also leverage our knowledge of industry best practices,” said Richard Falcinelli, vice president, LIU Marine Risk Engineering.
It’s the combination of deep expertise, extensive industry knowledge and a global perspective that enables LIU Marine to uniquely address their client’s safety challenges. Long experience has shown the LIU Risk Engineering team that a rigid process will not be successful. The wide variety of operations and safety challenges faced by marine companies simply cannot be addressed with a one-size-fits-all approach.
Therefore, the LIU SAFE program is defined by five core principles that form the basis of each project.
“Our underwriters, risk engineers and claims professionals leverage their years spent as master mariners, surveyors and attorneys to utilize the best project approach to address each client’s unique challenges,” said Falcinelli.
The LIU SAFE Program in Action
When your primary business is transporting dry and liquid bulk cargo throughout the nation’s complex inland river system, safety is always a top concern.
The risks to crew, vessels and cargo are myriad and constantly changing due to weather, water conditions and many other factors.
SCF Marine, a St. Louis-based inland river tug and barge transportation company and part of the Inland River Services business unit of SEACOR Holdings Inc., understands what it takes to operate successfully in these conditions. The company strives for a zero incident operating environment and invests significant time and money in pursuit of that goal.
But when it comes to marine safety, all experienced mariners know that no one person or company has all the answers. So in an effort to continually find ways to improve, SCF management approached McGriff, Seibels & Williams, its marine broker, to see if LIU Marine would be willing to provide their input through an operational review and risk assessment.
The goal of the engagement was clear: SCF wanted to confirm that it was getting the best return possible on its significant investment in safety management.
Using the LIU SAFE framework, LIU’s Risk Engineers began by sending SCF a detailed document request. The requested information covered many aspects of the SCF operation, including recruiting and hiring practices, navigation standards, watch standing procedures, vessel maintenance standards and more.
Following several weeks of document review the LIU team drafted its preliminary report. Next, LIU organized a collaborative meeting at SCF’s headquarters with all of the latter’s senior staff, along with McGriff brokers and LIU underwriters. Each SCF manager gave an overview of their area of responsibility and LIU’s preliminary findings were reviewed in depth. The day ended with a site visit and vessel tour.
“We sent our follow-up report after the meeting and McGriff let us know that it was well received by SCF,” Falcinelli said. “SCF is so focused on safety; we are confident that they will use the information gained from this exercise to further benefit their employees and stakeholders.”
“It was probably one of the most comprehensive efforts that I’ve ever seen undertaken by a carrier’s loss control team,” said Baxter Southern, executive vice president at McGriff, which also is based in St. Louis. “Through the collaborative efforts of all three parties, it was determined that SCF had the right approach and implementation. The process generated some excellent new concepts for implementation as the company grows.”
In addition to the benefits of these new concepts, LIU gained a much deeper understanding of SCF’s operations and is better positioned to provide ongoing loss control support.
“Effective safety management is about being focused and continuously improving, which requires complete commitment from top management,” Falcinelli added. “SCF obviously is on a quest for safety excellence with zero incidents as the goal, and has passed that philosophy down to its entire workforce.”
“SCF’s commitment to the process along with LIU’s expertise was certainly impressive and a key reason for the successful outcome,” Southern concluded.
There are many other ways that the SAFE program can help clients address safety risks. To learn more about how your company could benefit, contact your broker or LIU Marine.
