- A majority of the North Sea platforms are currently operating outwith life expectancy. Platform structural performance is impacted by the aggressive marine environment through material deterioration. Several catastrophic events (e.g. Piper Alpha 1993) have placed an increased focus on platform strength evaluation and many platforms have undergone significant structural changes. Modelling can inform platform strength evaluation. Our research into the design of new and assessment of existing offshore jacket platforms indicates that joint flexibility, piled foundations and geometrical imperfections should be accounted for. Significantly, disregarding these factors may lead to overly optimistic predictions. The paper won the Telford Premium Prize.
