Modeling Catastrophe Risk to Marine and Energy Exposure in the Gulf of Mexico Houston Marine Insurance Energy Seminar Hemant Shah, CEO Risk Management Solutions September 18, 2006
New Orleans, September 3 2005 • 70-80% of New Orleans flooded, • 55% of the city’s 147,000 properties inundated by more than 4 feet • Maximum flood depths 18 feet.
The Expansion into the Floodplain • Pumps initially deployed from 1913-1928
1915 “New Orleans” Hurricane • Cat 4 Hurricane, 20 miles east of New Orleans (Grand Isle) • “Whole country between Poydras and Buras inundated. Levees gone, property loss appalling. Life toll probably heavy. Conditions estimated worse than ever before. Relief needed. No Communications..." • Storm struck before the construction of the Industrial Canal • On the Mississippi River below New Orleans storm surge overtopped the levees below New Orleans and rose to 15-20 feet above sea level. • Swells rolled up the river in New Orleans 10-12 feet above high water. • Water was carried into Lake Pontchartrain and overflowed the existing levees to flood western part of the city • From the Old Basin canal (parallel to Orleans Avenue) to Broadway and from Claiborne Avenue to Lake Pontchartrain • Flooding 1-8 feet • After the passage of the storm the surge receded rapidly but the flood waters stayed in place for 3-4 days in New Orleans and had to be removed by the drainage system (from1915 Monthly Weather Review).
The Expansion into the Floodplain • Second generation of pumps elevated to be able to function after a flood Bayou St. Jean at Lake Pontchartrain
1947 Hurricane • Cat 3 directly over the City • Surge overtopped LakePontchartrain levees • 17th St Canal wall failed • Up to 6 feet of water in parts of Jefferson parish • Standing water for weeks • Removed through cutting and blasting holes in the levees

“I want to give positive assurance that our friends will find Miami this winter the same enjoyable, hospitable, comfortable vacation city it has always been. I predict that Miami will make a world record come-back…we are ready to resume our place as the playground of the world” Miami Mayor E.C. Pomfh …speaking six days after the September 18, 1926 storm struck south Florida Mayor Pomfh’s Vision…
1990 Population of Dade and Broward alone exceed that of all 109 coastal counties (TX – VA) in 1930 Of 67 coastal counties in LA ->FL, pop. density is 2.5X national average During the Florida construction boom from 1970 – 1990: 70% of buildings in Broward and Palm Beach counties built in this period 75% increase in the population density in SE Florida Commercial values almost tripled in value The trend continues; from 1990 to 2000: The population of Broward County increased by 29%, and Collier County by 65% Currently, 1,540 building permits issued in coastal counties every day Mayor Pomfh’s Vision…Realized

Offshore Platform Modeling FrameworkRMS RiskLink v6.0, Released May, 2006 Define Hurricane Claiming • Storm parameters • Basin-wide tracks, realistic time histories • Onshore and offshore “clash” • Time-stepping windfield calculations • Windspeed and wave height • Submarine landslide • Physical damage (PD) • Loss of production • BI, CBI, OEE
Recent Storms to Impact the Offshore GOM Plot of maximum windspeeds - 2002 to 2005 Lili, Ivan, Katrina & Rita
Recent Storms to Impact the Offshore Region • 94% of the 4,200 offshore platforms in GOM experienced Cat 1 winds or greater from 2002-2005
Hurricane Losses to Offshore ExposureIvan (’04), Katrina and Rita (’05) Obtained from various industry sources
Lessons Learned of Relevance to Offshore Energy • Frequency and intensity of hurricane activity • Likely to face elevated levels of hurricane activity over at least the medium term • Prior modeling practice, based on long-term historical averages, underestimated the occurrence of intense storms • Vulnerability to damage and insured loss • Physical damageability of platforms (et al) greater than previous expectation • Time element risks are significant, and must be modeled • Greater variability in risk to various classes of exposure • Making the transition from 1st to 2nd generation models

NOAA Declares the Onset of an El Niño • September 10th, 2006 “Scientists at the NOAA Climate Prediction Center reported that El Niño conditions have developed in the tropical Pacific and are likely to continue into early 2007…Ocean temperatures increased remarkably in the equatorial Pacific during the last two weeks.” "Currently, weak El Niño conditions exist, but there is a potential for this event to strengthen into a moderate event by winter…also, the development of weak El Niño conditions helps explain why this Atlantic hurricane season has been less active than was previously expected.” “El Niño typically acts to suppress hurricane activity by increasing the vertical wind shear over the Caribbean Sea region. However, at this time the El Niño impacts on Atlantic hurricanes are small. We are still in the peak months of the Atlantic hurricane season, and conditions remain generally conducive for hurricane formation.”

Climate Change Debate and Hurricane Activity • The WMO (World Meteorological Organization) has released a statement on the current state of debate • “The division in the community is not as to whether Global Warming can cause a trend in tropical cyclone intensities. Rather it is on whether such a signal can be detected in the historical data base.” • “Whilst the existence of a large multi-decadal oscillation in Atlantic tropical cyclones is still generally accepted, some scientists believe that a trend towards more intense cyclones is emerging.” • “No single high impact tropical cyclone event of 2004 and 2005 can be directly attributed to global warming, though there may be an impact on the group as a whole.” Prepared by the WMO/CAS Tropical Meteorology Research Program, Steering Committee for Project TC-2: Scientific Assessment of Climate Change Effects on Tropical Cyclones.
