Combined Power, Gas and Communication Umbilical Cables
OCEANS '76, 1976The continuing loss of life in the diving fraternity in the North Sea has resulted in the United Kingdom placing particular emphasis on safe diving. This paper describes combined power, gas and communication umbilical cables for saturation diving systems together with the disciplines and technology necessary for such cables and their associated winch ...

Three-Dimensional Dynamic Behavior of the Flexible Umbilical Cable System
Applied Mechanics and Materials, 2013 We extend an idea of the modeling flexible umbilical cable using a nonlinear finite element method to three-dimensional space. The umbilical cable is assembled by Reissners geometrically exact beam elements, which take account of the geometric nonlinearities of large rotation and displacement, and effects of axial load, transverse shear, torsion and ...

Rotary bending of marine cables and umbilicals
Engineering Structures, 1995The stress analysis of a marine cable or umbilical in a rotary bending test rig is presented. It is shown that the finite length of the test sample and the terminations have a significant influence on the stresses in the umbilical which is taken into consideration in determining the cyclic stress distribution in the helical components.

Umbilical cable recovery load analysis
China Ocean Engineering, 2013Umbilical cable is a kind of integrated subsea cable widely used in the exploration and exploitation of oil and gas field. The severe ocean environment makes great challenges to umbilical maintenance and repair work. Damaged umbilical is usually recovered for the regular operation of the offshore production system.

An Integrated Environment for Design and Analysis of Umbilical Cables
Volume 5A: Pipelines, Risers, and Subsea Systems, 2017The design of an umbilical cable begins with the definition of the operational functions it must implement and the environmental conditions to that it will be subjected to. Those functions suggest the components that it must have, usually chosen from a pre-defined set.

Cabling umbilical and array layout
2013This chapter discusses the case of dynamic cables and subsea connectors for which the design requirements and specifications posed by marine energy applications are distinctly different from the ones typically applied in the offshore industry. Bespoke solutions are needed in this case as the design of the connection is largely dependent on the device ...

Tow/umbilical cable system for Deep Venture I cable burial plow
OCEANS 2000 MTS/IEEE Conference and Exhibition. Conference Proceedings (Cat. No.00CH37158), 2002This paper describes the tow/umbilical cable system used to tow the Deep Venture I cable burial plow. The unique demands of this cable plow, including towing at 3 knots from a work boat rather than a cableship, requires a special solution for the tow/umbilical cable system.

A Finite Element Model for Umbilical Cable Crushing Analysis
Volume 5A: Pipeline and Riser Technology, 2015Umbilical cables are essential elements of offshore floating production systems. Due to their complexity, the offshore industry regularly counts on numerical tools to perform design assignments. One of these assignments is to evaluate strains and stresses states in all components due to distinct sets of external loads. The main purpose of this paper is

Automatic Control and Guidance Method of ROV with Umbilical Cable
IFAC Proceedings Volumes, 2007Abstract For the remotely operated vehicle (ROV) with an umbilical cable, it becomes difficult to guide it to a target as the depth increases. Especially, the vehicle for the working in the deep sea under current disturbance, the control to reach the target is the most important and difficult problem, because the tension of the umbilical cable, which

Synchronous clamping control of marine umbilical cable tensioner
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2012The umbilical cable tensioner is a core component of deep-water oil and gas development, and it can lay and recover the umbilical cables to ensure the transmission of communication signals, electric signals or liquid injection. The displacements of tensioner’s clamping hydraulic cylinders, which are not synchronized as the nonlinear electro-hydraulic ...
