JACKET DUCTILITY DESIGN

The Goodwyn A steel jacket, located on the North West Shelf of Western Australia and operated by Woodside Offshore Petroleum is designed with specific requirements for resistance to progressive collapse under extreme or accidental events. Jacket structure reliability is established using static nonlinear pushover analysis for intact and damaged configurations to achieve specified reserve strength criteria. The paper describes the ductility design process which starts with a jacket design that satisfies the working stress requirements of API RP 2A.
