..., the impact on the design procedures are considered. Stability analysis is performed for a few cases to correlate the actual displacement of pipelines with theoretical simulations. Introduction Hurricane Ivan was a long-lived hurricane that made landfall twice along the U.S. coast and reached Category 5...

... undertaken [7, 9]. However the motions observed during the time domain analyses were so severe that the proposed mooring system would not have been able to hold the FPSO on station. This unstable behaviour was not predicted by the well established stability analysis techniques. Review of the literature...

... of this paper. Motion analysis of permanent offshore floating units is normally performed taking into account the specific site environmental conditions. On the other side, stability analysis is normally performed with worldwide limits criteria. The result of this is a predicted motion behavior based...

... on a deterministic approach where the margin of safety is quantified by the safety factor. Many of the parameters that are used in a stability analysis, in particular the soil shear strength, are inherently uncertain. The geotechnical engineer tries to deal with the uncertainties by choosing reasonably conservative...
