“…The fatigue damage is highest at the touch down zone. Assumption can be made regarding the effect of seabed material affect the fatigue life in the TDZ; for example, a rigid seabed can give high levels of conservatism when compared to an elastic seabed ( [15] and [28].…”

Controlling subsea oil and gas production systems fibre optics, power cables and tubes for the chemical for injection and fluid for hydraulic are arranged in helical bundles in successive layers. Shaped thermoplastic fillers are used to separate components and out voids in the cross section. If necessary, armour provide strength for the dynamic loads. This paper describes the application of 3D finite element method to assess the structural Integrity of subsea umbilicals, including the interaction between the constituent elements. uses a global analysis to determine the internal force analyses (sub-modelling) for detailed stress evaluation. is used for this purpose, due to its capability problems under severe discontinuities due contact conditions. This paper also discusses the umbilicals interaction w seabed. The focus of this paper is on the fatigue life calculation.
