Abstract | This study presents the axial behavior of umbilical cable due to the self weight loading during the installation. The structure configuration of umbilical must be able to deal with tensile capacity to resist self-weight loading from umbilical cable. In this study, Power cable, Telecommunication cable and Complex Umbilical are used to investigate the behavior under self weight loading. The behavior of umbilical cables subjected to tension has been studies by performing Finite Element Analysis taken loading under water depth 100 m and 1000 m. Closed-form solution by Knapp and Le (1991) is performed to compare the result of Finite Element Analysis. The different result of Finite Element Analysis and Closed-form solution lead to propose modified closed-form solution. Modified closed-form solution is constructed by combining closed-form solution of Knapp and Le (1991) with effect of pitch radius and lay angle. The tension distribution of modified closed-form solutions presents the excellent result in Lang lay wire constructions. Moreover, the tension distribution of modified closed-form solution is greatly improved tension distribution particularly on core layer in regular lay wire constructions. |
