On Modelling Alternatives of Non-Critical Components in Dynamic Offshore Power Cables
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...

An anisotropic friction model in non-bonded flexible risers
The present paper addresses small scale friction tests and an anisotropic friction model to predict friction for the interface between the anti-wear tape and tensile armors in non-bonded flexible risers. Small scale friction tests were carried out to study the static and dynamic friction behavior...
OMAE2017-61117 The Study on the Influence of Pipe-Soil Interaction on VIV for Different Free Span Types
Subsea pipeline laid on the seabed will experience free span when the lay path is long and seabed is rugged. Hydrodynamic loads caused by the currents around the pipeline can induce oscillations in both cross-flow and in-line directions. This phenomenon is called vortex-induced vibration (VIV) which...
OMAE2017-61069 The Study of a New Concept of Flexible Pipe With Carbon Fiber/Epoxy Reinforced Inner Sheath
Flexible pipe has been widely used in offshore industry for many years. The traditional composite structure of flexible pipe consists of many layers, including multiple metallic layers, such as tensile armor, pressure armor and carcass, as well as nonmetallic layers, such as sheath and liner...
OMAE2017-62644 The Effect of Stick Stiffness of Friction Models on the Bending Behavior in Non-Bonded Flexible Risers
This paper investigates the effect of stick stiffness on the bending behavior in non-bonded flexible risers. The stick stiffness was normally implemented in the friction model for calculating the friction stress between layers in such structures. As the stick stiffness may be too small to achieve...
