Subsea/Underwater Umbilical Cable & Umbilical Cable Connector

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.

Umbilical Cable Connector description

The umbilical connector carries power and communications between the subsea unit and topside unit. It is a wet-mateable subsea connector which is designed to be made and broken in wet conditions topside. It should not be disconnected subsea.

The deck integration cable can be connected directly to this connector to test and configure the system before an umbilical or subsea whip is connected for deployment subsea. Ensure that the orientation of the missing pin is correctly aligned when mating the plug and socket. If the connectors are mis-aligned and the connection is forced together then damage may occur to the plug, socket or whole unit.
