Residual strength assessment and repair of damaged offshore tubulars
- Lehigh Univ., Bethlehem, PA (United States)
The results of several current research programs related to the behavior of dented and corrosion-damaged tubular brace members and their repair is presented. Investigations were conducted involving large-scale testing and analytical studies. The analytical studies involved assessing the ability of several different methods of analysis, including simple engineering calculations and more sophisticated nonlinear finite element analysis, to predict damaged and repaired member behavior. The results of the test programs indicated that a significant amount in member deterioration could occur due to either dent or corrosion damage. The extent of the ability of a repair to reinstate a damaged member to its original design strength was found to depend on the extent of the damage. The accuracy and reliability of the analytical methods to predict damaged member behavior are illustrated. 29 refs., 25 figs., 7 tabs.
