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.”
Getting From Here to There
Companies within the energy industry are facing growing risks as their trucks roll through urbanized areas and rural roads not designed for heavy-duty traffic.
With the boom in oil exploration comes the need to move high-value machinery, hazardous materials and hazardous waste, and natural resources at seemingly ever-faster paces into locations previously untouched by the industry.
The expansion of the U.S. energy business is evident.
From February 2010 to February 2013, onshore oil production within the lower 48 states increased by 64 percent, according to the U.S. Energy Information Administration, and the number of natural gas wells found in shale plays in the United States increased to 10,173 in 2011, from 5,531 in 2009. From 2010 to 2011, shale drilling expenditures increased by 88 percent, totaling $65.5 billion, according to the American Petroleum Institute.
As a result of this expansion, organizations face greater reputational and environmental liability risks, and may also experience an increase in third-party liability claims.
Risk reduction is possible for companies that develop a robust and proactive risk management strategy that makes safety a high priority.
Fleet operators understand that their reputation is on the line with every accident, whether in the headlines or not. Organizations’ health and safety performance data can hinder a service company’s ability to win contracts. Their entire safety record is made public through the Department of Transportation’s Safety and Fitness Electronic Records (SAFER) system.
Any future business they get within the oil business is contingent on their risk management performance and regulatory compliance. This concern is shared by every link in the energy supply chain, as every ancillary operator in the business — from drilling, to well-servicing and beyond — has drivers, trucks and exposures.
A 21st century energy company understands the need to evaluate their safety risks and develop effective risk mitigation strategies.
Contributing to the transportation risk scenario are key factors such as high levels of driver demand, a relatively inexperienced driver pool across the U.S., increased state and federal regulatory oversight, and drivers operating in unfamiliar locations.
Recognizing the broad and ever-changing nature of transportation risks is crucial, and companies working to keep these exposures in check do so through the development and implementation of a systemic approach to fleet risk management and loss control that includes the following steps:
1. Gap Analysis/Regulatory Review
The first step in a risk management program is to gain an understanding of the current state of affairs.
Part of this involves ensuring that a Motor Carrier Consensus Form is accurate. One good indicator of safety is the SMS BASIC percentile rank that can be found in the monthly CSA Data Preview.
Inspection and violation histories can also help companies identify patterns and trends, revealing which areas of their transportation program (including their own business processes) require improvement.
2. Safety Training
Training involves making drivers aware of Department of Transportation rules. Even experienced truckers, upon coming to the energy business, might need training on the challenges of driving on smaller roads through towns and the varied other operating environments they experience.
Part of any training program must also involve increasing all drivers’ awareness that their performance on the road directly affects the company.
The Consumer Energy Alliance Trucking Safety Task Force recommends making sure drivers know that no load is worth sacrificing safety standards or violating rules.
3. Driver Vetting
This can be a daunting task. The economy of the oil business dictates that operators are active as much as possible while the prices are high; for gas, despite the lower commodity prices, wells are being drilled more and more.
Drivers are wanted. Screening procedures and drug testing are more than ever a necessity to mitigate fleet risk.
4. Periodic Re-Evaluation
Repeat steps one, two and three on a regular basis. As the Consumer Energy Alliance Trucking Safety Task Force guidelines suggest, meet with community members and leaders, local law enforcement and emergency to understand their safety concerns and address them in upcoming training as needed.
Meet regularly with the drivers themselves and ensure they are aware of changes on the ground.
The domestic energy industry is experiencing an exciting and prosperous moment, yet with growth in exploration and production comes growth in risk and its consequences — particularly those centered around transportation.
Some larger oil and gas service companies have already spent millions of dollars to understand and mitigate their fleet risk. Other companies are not quite as far along. Yet all service providers appreciate that creating a safety culture can only help them in the future.
The Promise of Technology
The field of workers’ compensation claims management seems ideally suited as a proving place for the power of technology.
Predictive analytics in the hands of pharmacy and medical management experts can give claims managers the data they need to intervene in troublesome claims. Wearables and other mobile technologies have the potential to give healthcare providers “real-time” reports on the medical condition of injured workers.
Never before have the goals of quick turnaround and transparency in managing claims appeared so tantalizingly achievable.
In the effort to learn more about technology’s potential, in September, Risk & Insurance® partnered with Duluth, Ga.-based Healthcare Solutions to convene an information technology executive roundtable in Philadelphia.
The goal of the roundtable was to explore technology’s promise and to gauge how advancements are serving the industry’s ultimate purpose, getting injured workers safely back to work.
Big Data, Transparency and the Economies of Scale
Integration is a word often heard in connection with workers’ compensation claims management. On one hand, it refers to industry consolidation, as investors and larger service providers seek to combine a host of services through mergers and acquisitions.
In another way, integration applies to workers’ compensation data management. As companies merge, technology is allowing previously siloed stores of data to be combined. Access to these new supersets of data, which technology professionals like to call “Big Data,” present a host of opportunities for payers and service providers.
Through accessible exchange systems that give both providers and payers better access to the internal processes of vendors, a service provider can show the payer the status of the claim across a much broader spectrum of services.
“One of the things I see with all of this data starting to exchange is the ability to use analytics to predict outcomes, and to implement workflows to intervene.”
–Matthew Landon, Vice President of Analytics, Bunch CareSolutions.
“Any time that we can integrate with a payer across multiple products such as pharmacy, specialty and PPO services, what it does is gives us a better picture of the claim and that helps us to drive better outcomes,” said roundtable participant Chuck Cavaness, chief information officer for Healthcare Solutions.
Integration across multiple product lines also produces economies of scale for the payer, he said.
Big Data, according to the roundtable participants, also provides claims managers an unparalleled perspective on the cases they manage.
“One of the things that excites us as more data is exchanged is the ability to use analytics to predict outcomes, and to implement workflows to intervene,” said roundtable participant Matthew Landon, vice president of analytics with Lakeland, Fla.-based Bunch CareSolutions, A Xerox Company.
Philadelphia roundtable participant Mike Cwynar, vice president of Irvine, Calif.-based Mitchell International, agrees with Landon.
“We are utilizing technology to consolidate all of the data, to automate as many tasks as we can, and to provide exception-based processing to flag unusual activity where claims professionals can add value,” Cwynar said.
Technology is also enabling the claims management industry to have more productive interactions with medical providers, long considered one of the Holy Grails of better case management.
Philadelphia roundtable participant Jerry Poole, president and CEO of Malvern, Pa-based claims management company Acrometis, said more uniform and accessible information exchange systems are giving medical providers access to see how bills are moving through the claims manager’s process.
“The technology is enabling providers to call in or to visit a portal to figure out what’s happening in the process,” Poole said.
Another area where technology is moving the industry forward, according to the Philadelphia technology roundtable participants, is mobile technology, which is being used to support adjustors and case managers and is also contributing to quicker return to work and lower costs for payers.
The ability to take a digital tablet to a meeting with an injured worker or a health care provider is allowing case managers to enter data and give feedback on a patient’s condition in real time.
“Our field-based case managers have mobile connectivity to our claims systems that they use while they’re out of the office attending doctor’s appointments, and can enter the data right there into the system, so they’re not having to wait until they are back at the office to enter critical clinical documentation,” said Landon.
Injured workers that use social media, e-mail and the texting function on their mobile phones are staying in better touch with those that are charged with insuring that they are in compliance with their treatment plans.
Wearable devices that provide in-the-moment information about an injured workers’ condition have the potential to recreate what is known in aviation as the “black box,” a device that will record and store the precise physical state of an employee when they were injured. Such a device could also monitor their recovery process.
But as with many technologies, worker and patient privacy also needs to be observed.
“At the end of the day, we need to make sure that we approach technology enhancement that demonstrates value to the client, while ensuring patient advocacy,” Landon said.
As payers and claims managers set out to harness the power of computing in assessing an injured worker’s condition and response to treatment, the cycle of investment in companies that serve the workers’ compensation space is currently playing a significant role.
The trend of private equity investing in companies that can establish one-stop shopping for such services as medical case management, bill review, pharmacy benefit management and fraud forensics has huge potential.
“Any time that we can integrate with a payer across multiple products such as pharmacy, specialty and PPO services, what it does is gives us a better picture of the claim and that helps us to drive better outcomes.”

The challenge now facing the industry, one the information technology roundtable participants are confident it can meet, is integrating those systems. But doing so won’t happen overnight.
“There’s a lot of specialization in the industry today,” said Jerry Poole of Acrometis.
Years ago there was a PT network. Now there’s a surgical implant guy, there’s specialized negotiations, there’s special investigations, said Poole.
The various data needs to be integrated into an overall data set to be used by the carriers to help lower the cost of risk.
Securing Sensitive Information
Long before hackers turned the cyber defenses of major national retailers inside out, claims management professionals have focused increased attention on the protection of data shared across multiple partners.
Information security safeguards are changing and apply to what technology pros refer to “data at rest,” data that is stored on a particular company’s servers, and “data in flight,” data that is transferred from one user to another.
Mitchell’s Cwynar said carriers want certification that every company their data is being sent to needs to have that information and that both data at rest and data in flight is encrypted.
The roundtable participants agreed that the industry is in a conundrum. Carriers want more help in predictive analytics but are less willing to share the data needed to make those predictions.
And as crucial as avoiding cyber exposures and the corresponding reputational damage is for large, multinational corporations, it is even more acute for smaller companies in the workers’ compensation industry.
Healthcare Solutions’ Cavaness said the millions in loss notification and credit monitoring costs that impact a Target or a Home Depot in the case of a large data theft would devastate many a workers’ compensation service vendor.
“They’d be done in a minute,” Cavaness said.
The barriers to entry in this space are higher now than ever before, continued Cavaness, and companies wishing to do business with large carriers have the burden of proving that its security standards are uncompromising.
Workers’ compensation risk management in the United States is by its very nature, complex and demanding. But keep in mind that those charged with managing that risk get better results year after year.
Technology has a proven capability to iron out the system’s inherent complications and take its more mundane tasks off of the shoulders of case adjustors.
