Abstract
Modelling alternatives for non-critical components in dynamic offshore power cables are systematically investigated with the aim to clarify the extent to which these components in finite element modelling (FEM) should be considered depending on the purpose of the analysis. Level of simplification, choice of element type and determination of contact stiffness are among the key parameters when modelling such components. Mesh sensitivity on sheath layers, filled bodies and tensile armor wires is carried as well. Their effects on physical properties of the cross section, stick and slip characteristics of helical components are investigated. Axial stress in the tensile armor wires is particularly studied. Software program UFLEX is used for the investigation.
