THE VULNERABILITY OF GULF OF MEXICO SHIPYARDS
TO COASTAL FLOODINGAS A RESULT OF STORM SURGE
By Capt. Christopher Bowman
Increasing Number of Deepwater Projects
Increasing complexity and size enhances exposure and costs.
Flooding Risk Has Always Been There
The value of the assets has changed, subsequently changing the risk.
Storms Appear More Intense and Unpredictable
The need for more thorough contingency planning to improve risk
identification and risk mitigation.
Who Benefits From Contingency Procedures?
• Underwriters – Reduced Risk Exposure
• Brokers – Representation of Competent Assureds
• Assureds – Minimize Damages to Assets / Project Delays
• Shipyards – Minimize Damages to Assets / Equipment
• Government – Reduce Risk to Infrastructure
• Civilian Population – Reduced Risk to Personal Properties
Three Cases Different Unique Risks in the Gulf of Mexico
• Pascagoula, MS / Mobile, AL
• Ingleside, TX
• Brownsville, TX

Site Specific Soils Analysis
Hull / Leg Wind-Load Calculations
Preload Requirements
Summary and Conclusions
Gulf Coast Shipyards will always be exposed to the threat of severe coastal
flooding arising from any given tropical event.
The risks and exposures to these facilities is always changing, driven by
season and current scopes of work.
Assessing the risks and exposures frequently is essential to insure that
Contingency Plans and Hurricane Preparedness Plans are up to date for the
current scopes of work.
Contingency Plans and Hurricane Preparedness Plans have a significant
financial impact on these facilities as they often require volumes of resources,
advance planning time and adequate time for full implementation.
Shipyards carry the burden to protect their assets, the assets of their Clients,
the financial impacts to insurance markets and to reduce the potential for
interruptions to the global offshore oil and gas industry.
