Umbilical cable is an important facility in the subsea production system for the offshore oil exploitation. It provides a control and communication link between the surface vessel and the subsea equipment. The umbilical cable is a composite structure that is composed of multiple components and various materials. A typical umbilical cable usually consists of tubes or hoses, optical fibre cables, electrical cables, inner sheaths and fillers which are assembled into an inner core. Steel armor wires are used to provide the tension capability or to achieve the necessary stability. The outer sheath provides protection for the inner components (ISO, 2009). Umbilical cables should maintain sufficient tension stiffness to withstand large loads induced by self-weight, wave and the motion of the surface vessel, which leads to an urgent requirement for the prediction of the mechanical behaviour.
