Surface Roughness Analysis of Subsea Cables/Umbilicals
Journal of Marine Science and EngineeringSurface roughness is an important factor influencing subsea cable/umbilical–soil interaction. The cable/umbilical goes through several steps before being laid on the seabed, including production, spooling, unspooling, and installation on the seabed. Yet,

Numerical and Experimental Analysis of Umbilical Cables under Tension [PDF]
Advanced Composites Letters, 2017 Umbilical cables are composite structures that consisting of metallic material and polymeric material. Analysing tension behaviour under axial loading is a key requirement to design the structure. A full three-dimensional finite element model is established in which the effect of radial deformation is given more attention.

Study Simulation of Umbilical Cable for Underwater Vehicle [PDF]
Bulletin of the Polytechnic Institute of Iași. Machine constructions Section, 2021 Abstract This paper presents a series of analyses regarding the tethered umbilical cable in uniform current cable from the composition of the underwater remotely operated vehicle (ROV). The remotely operated vehicle is used in different undersea operation when it is important to control and determine precisely the disturbance forces ...

Integrated Control Scheme for an Improved Disturbance-Free Payload Spacecraft
Aerospace, 2022 For a novel disturbance-free payload (DFP) spacecraft, it is difficult to isolate the low-frequency disturbances owing to the umbilical cables, which decreases the pointing accuracy and stability of the payload.
