Summary
Investigation of the Typhoon tension-leg platform’s capsizing during Hurricane Rita identifies loss of mooring-system integrity at pontoon 1 as the most probable cause. Hull inspections, ROV surveys, photogrammetry and modelling examine connector damage and alternative explanations. The report records hydrocarbon pollution and recommends studying the mooring system’s continued acceptability.
