“…It was found that the failure is by local buckling and yielding of base plates under the action of axial compression, but if the lateral load is a major component of the loading the stiffened plate behaves as an orthotropic plate and the failure is by the formation of a mechanism along the diagonals. Hu et al [9] conducted tests on 12 full-scale stiffened plates with T stiffeners. The authors measured the residual stresses and initial imperfections.…”

“…When minor damage has occurred, it becomes important to determine the ultimate strength and reliability of an ageing structure taking into account strength reduction and load shedding following denting. Hu et al, [20] present basic data about load shortening curves for stiffened panels including 'asbuilt', 'deformed' and 'damaged' specimens.…”

This paper presents a review of the state-of-the-art of risk assessment as it applies to the hull structures of FPSOs. Risk definitions are examined critically to determine how they should be applied in this case. The roles of human and organisational errors and their proper identification during design of intact and damage scenarios are discussed. It has long been accepted that FPSOs and trading tankers are subject to different environmental loading conditions. Even more substantial differences become evident when operating practices are examined and it is realised that to manage risk properly these differences need to be reflected in design and the preparation of operation procedures. Against a background of code development, design experience and detailed knowledge of many things that have gone wrong, the review examines: risk evaluation for hull structures; specific risks relating to FPSO hull-structure configurations; environmental issues for a moored FPSO; operational issues and risks arising from interaction between the hull and the mooring system.

“…Moreover, the obtained results could be rather controversial and not meaningful enough due to the inherent variations which are suffered by the intervening factors [8][9][10][11][12][13]. On the opposite, numerical simulation of buckling phenomenon occurring in stiffened plates enables to analyze the infl uence of key geometric and loading parameters on bucking strength more directly.…”

Considering a stiffened panel made from an elastic homogeneous and isotropic material which suffers a single localized initial geometric imperfection, assessment of the buckling limit state under in-plane uniform axial compression in the direction of stiffeners was performed. Giving a topological configuration of the stiffened plate, focus was aimed at the combined effect resulting from geometrical dimensions and localized defect characteristics. The perfect stiffened plate taken as reference and diverse imperfect stiffened plates suffering a single localized initial geometric defect of the form of a square depression were analyzed in this work. Extensive parametric finite element simulations were performed according to full factorial design of experiment tables that were built on key intervening factors. It was found that the main parameters controlling the buckling stress for the perfect plate are the plate width, then the web height and width, then finally the interaction between plate width and web height. In case of imperfect plates, the most adverse situation was obtained with the defect placed on the intermediate segments of the stiffened plate. A reduction of the buckling stress as low as 56% was reached in this situation. The main factors influencing the buckling load for the imperfect plate differ according to the defect configuration.
