Abstract
The main technological challenge for ultra-deep-water umbilical is the reliability of the integration of high-voltage power cables and production umbilical with respect to electromagnetic interference and high thermal effects. The aim of this study is to evaluate the thermal and electromagnetic characteristics of a large bore central pipe and the polyvinyl chloride matrix, various metallic tubes for heating, hydraulic and service fluids, and the electrical/fiber-optic cables for development of design methodologies. Thermal and electrical analyses are performed to insure that the cable design will comply with the specification and is suitable for all operating conditions. A detailed numerical analysis-based parametric study was carried out with the aim of developing design procedure and making optimum integrated production umbilical umbilical system's recommendations.
