A leading cause for offshore decommissioning is connected with assessment of increasing level of risk due to progressive structural damage and danger potential, in both structural and technological collapse, taking into account the environmental conditions and operational loads for which structure undergoes. The purpose of this paper is to express the vulnerability due to fatigue phenomenon of structural elements - studied on a model corresponding to self lifting Romanian offshore platform "Gloria" - as annual yie...

Design of a structure together with monitoring the structural response to dynamic loads (seismic and hydrodynamic), fatigue aging, the possibility of successive degradation, resilience respective vulnerability are strongly influenced by the chosen calculus model, and a laborious probabilistic calculation. For particular case of offshore structures this implies the connection between the actions of the environment: wave histograms, wind action, foundation collapse, structure, technological activities and so on.
