Storm Overload Examples

Typhoon TLP after Rita

What does O&G tell us?

 There is no one answer

– There are central tendencies but variations are

significant

 There are many options for “low cost” minimal

structures

 Simple solutions are typically more cost effective

(less risky) that complex alternatives

 Major cost efficiencies will come from EPIC

competition

– Innovative construction methods and equipment

Code Benchmark Joint Industry

Project

JIP STUDY

 Objective

– Compare API and IEC standards for OWTG in US waters

 Direct comparison

– Performance requirements (50 vs 100 year storm)

– Design methodologies

 Reliability assessment

– Inherent levels

– Regional variability

– Variability with concept type

 Assess cost impact for different performance
