Katrina’s Lessons in Windstorm Risk Management

Hurricane Katrina, which pummeled the Gulf Coast of the United States 10 years ago on Aug. 29, has proven to be the deadliest and costliest disaster on record. The 2005 Atlantic hurricane season was the most active in recorded history with more than 30 tropical and subtropical storms, including 15 hurricanes.

According to the study, Hurricane Katrina 10: Catastrophe Management and Global Windstorm Peril Review by Allianz Global Corporate & Specialty, it was predicted that hurricanes would become more frequent and intense after 2005, however, “In reality, the exact opposite has occurred,” Andrew Higgins, technical manager, Americas at Allianz Risk Consulting explained in the report. Instead, there has been a reduction in Atlantic hurricane activity during the last 10 years, with 2013 seeing the fewest Atlantic basin hurricanes since 1983. “These results illustrate the fact that we do not fully understand the complex climate variables that affect hurricane activity,” he said.

Because Katrina’s impact was so devastating and widespread, many changes have since been made. New Orleans has built a new system of levees, for example. Flooding caused by Katrina revealed the state of the levee systems in the U.S. to be substandard and in need of repairs estimated at $100 billion,the National Committee on Levee Safety found. “There are many levee systems throughout the U.S. that would reveal similar deficiencies if subjected to the same level of scrutiny as those in New Orleans,” according to the study.

“Katrina will always be remembered as an extraordinary natural disaster that affected millions of individuals and businesses and left an indelible impact on the global insurance industry,” Hugh Burgess, head of corporate lines at AGCS, said in a statement. “Even without considering the influence of climate change, the prospect of increasing losses due to storms is more of a result of continued economic development in hazard-prone developed coastal areas. Preparedness limits windstorm exposure and Katrina has taught us many lessons on this front.”

Top lessons from Hurricane Katrina:

1. Storm surge impact and risk modeling

“Storm surge modeling prior to Katrina essentially assumed that the height of the storm surge was a function of the maximum sustained winds,” Higgins said. “Katrina clearly showed that there are other factors that affect storm surge height… We have learned that in addition to wind speed, the physical size of the hurricane can affect the storm surge. Camille’s hurricane-force winds extended 60 miles from the storm center, while Katrina’s extended 120 miles. The larger size of Katrina was a major factor in pushing more water onto the shore.”

2. Flooding threat

The flooding caused by Katrina showed that the conditions of the levee systems in the U.S. are very poor. “The 2013 Report Card for America’s infrastructure developed by the American Society of Civil Engineers rates the levees in the U.S. as a D-,” Higgins said.

3. Wind damage prevention

Substantial wind damage occurred to structures that experienced hurricane force winds from Katrina, despite the fact that the recorded wind speeds were less than the wind design speeds. So what happened? “Most of the wind damage occurred to the building envelope,” Higgins explained. “That includes the roof covering, walls and windows. If the building codes had been strictly followed, the wind damage would have been greatly reduced. Poor workmanship and a lack of knowledge were the primary culprits.” He added, “Today, the Gulf Coast is in a better position to withstand the effects of a hurricane due to better education, improved construction guidelines and increased third party inspection.”

4. The importance of business continuity

After widespread catastrophes businesses typically relocate, meaning the client base can diminish until recovery progresses. The key to recovery is to establish a plan in advance that identifies clear priorities for attention to crucial operations, so the business can get back up-and-running as quickly as possible.

5. Insurance coverage issues

While insurance claims settlement levels from Katrina were high, it’s imperative to know what’s protected ahead of time. Many insureds were surprised to find out they were not covered for storm surge losses, the main coverage issue resulting from the storm. Whether damage was caused by wind or water became a key focus of post-Katrina litigation.

6.  Unexpected impact of demand surge

Demand surge is a post-catastrophe complication which can have not only catastrophe-related consequences in terms of rising prices due to a shortage of available goods, but other loss consequences as well. For example, a shortage of American-made drywall because of the demands of rebuilding led to a significant increase in imports of defective drywall manufactured in China. This resulted in a number of environmental issues and eventual litigation, particularly in the storm-affected states of Florida and Louisiana.

Allianz concluded that businesses need to start early to prepare for the worst-case scenario. “Businesses need to be sure to have tested business continuity plans and especially communications cascades in place and have insurance policies at a safe location,” advised Andreas Shell, Head of short-tail claims at AGCS. “Creating a separate booking account to which businesses can record hurricane-related damages to easily identify the loss incurred can also help.”

Terry Campbell, regional claims head, Americas at AGCS noted that every company should take these steps to ensure the claims settlement process runs as smoothly as possible after a windstorm event: “Follow the protocol outlined in the catastrophe response plan. If there isn’t one in place, one should be immediately developed for that event. Ensure there is adequate staff to respond and that there is ongoing communication to include scheduled meetings to discuss progress as well as issues, problems etc. These can be done as frequently as necessary,” he said.

Marine Losses Continue Downward Trend

The marine industry continued to see a steady decline in the number of large ships losses globally since 2002, with 94 ships lost in 2013, down 20% from 117 reported in 2012, according to a study by Allianz.

The “Safety and Shipping Review 2014” by Allianz Global Corporate & Specialty found that of ships lost, the largest number, 32, were cargo vessels; 14 were fishing vessels; and 12 were bulk shipments. Only six passenger ships were lost, the survey found. The most common cause of losses in 2013, and over  the last 12 years, was foundering (sinking or submerging). The demise of 69 ships accounted for nearly three-quarters of all losses—with bad weather a significant driver.

Worldwide there were 1,673 losses from Jan. 1, 2002-Dec. 31, 2013, with an average of 139 per year. The top geographic area for losses has been South China, Indo China, Indonesia and Philippines. The area including British Isles, North Sea, English Channel and Bay of Biscay is still ranked fourth, despite improvement. With 45 losses overall, the U.S. eastern seaboard improved in 2013, dropping out of the top 10 regions.

According to the study, January is the worst month for all casualties in the Northern Hemisphere. There were 23% more losses in January compared with the quietest month, June. In the Southern Hemisphere July sees 41% more losses than April.

The majority of losses are caused by machinery damage, the reason for most losses in marine insurance. Statistics from the International Union of Marine Insurance (IUMI) report that 40% of hull claims are machinery damage and account for 20% of costs.

The review found that while piracy is still a threat, it has also subsided. Piracy at sea reached its lowest levels in six years, with 264 attacks recorded worldwide in 2013, a 40% drop since Somali piracy peaked in 2011. Fifteen incidents were reported off Somalia in 2013, including Gulf of Aden and Red Sea incidents, down from 75 in 2012, and 237 in 2011 (including attacks attributed to Somali pirates in Gulf of Aden, Red Sea and Oman).

According to the study: “The very real threat of piracy for ships operating in the Gulf of Aden reached the general public last year as the Hollywood Oscar-nominated blockbuster Captain Phillips was released. Tom Hanks played the lead as the master of the pirated Mærsk Alabama, broadcasting the piracy problem to a much wider audience and raising awareness of its consequences. The steps that the international maritime community has taken to reduce the threat of piracy in the Gulf of Aden have been extremely successful with the number of ships seized and hostages taken in 2013 significantly down on 2012.”

Lower losses overall were attributed to a number of factors including increased regulation, which has helped the maritime industry improve its safety record. Because the quality of operations varies in different regions, however, there is a big need for universal regulations on ship safety to reduce the risk of casualties and loss of life, the survey concluded.

 

Weather Risks Often Overlooked

Unpredictable weather is a risk that can’t be put off or ignored. In fact, insurer payouts for weather-related catastrophes rose from $15 billion a year between 1980 and 1989 to a staggering $70 billion annually between 2010 and 2013, a study found.

While major weather events are a focus of businesses, small events can still have a big impact, according to The Weather Business: How Companies Can Protect Against Increasing Weather Volatility by Allianz Global Corporate & Specialty.

Even though weather volatility is shown to be rising globally, organizations are still failing to protect their revenue from the risks of changes in temperature, snowfall, wind levels, rainfall and too much sun, the report found. Changes in weather can also impact a number of industries including construction, energy, retail, tourism, food, distribution and transport.

Bad weather, however, is no longer an excuse for company stakeholders. Analysts, lending and rating agencies are increasingly looking at whether weather risks are included in a company’s risk management program, the study found.

Weather risk management can help companies hedge the risk posed by fluctuations in weather, similar to how companies already combat the threats of interest rate and foreign currency exchange movements, the report said.

Managing Small Business Risk

As any risk manager can tell you, risk knows no market segment. Large businesses with their multi-million dollar losses may get more attention but small- and medium-sized enterprises (SMEs) face risks as well. The difference for these smaller businesses is that the losses they face can’t always be absorbed into their balance sheet. Losses that would be relatively minor for their larger counterparts, could be devastating and could even force an SME to close its doors forever.

This is why, according to a survey by UK insurer Premierline Direct (part of the Allianz UK Group), it is interesting to see that despite being aware of, and having encountered, many common risks like customer non-payment, supplier issues and natural disaster losses, not all SMEs have been spurred to take action to mitigate future risk. One-fifth of UK SMEs surveyed not only do not have anyone who is responsible for managing risk, but have no plans to manage risks in the future. One-quarter do not consult with any specialists for risk management advice. Of course, the majority of SMEs do take risk management measures but closing the gap for the remaining businesses should be a priority.

To illustrate their findings and offer some tips on how SMEs can manage their risks more effectively, Premierline Direct provided the following infographic.
