Tow/umbilical cable system for Deep Venture I cable burial plow

OCEANS 2000 MTS/IEEE Conference and Exhibition. Conference Proceedings (Cat. No.00CH37158), 2002
This 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 Approach for Calculating Electrical Parameters of Umbilical Cables

IEEE Transactions on Power Delivery, 2009
This paper presents a systematic approach for calculating electrical per-unit-length parameters of signal cables by the Finite Element Method. The associated software (UFIELD) has been specifically adapted to umbilical cables used in offshore control applications.

A Finite Element Model for Umbilical Cable Crushing Analysis

Volume 5A: Pipeline and Riser Technology, 2015
Umbilical 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, 2007
Abstract 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, 2012
The 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 ...

Dynamic analysis of umbilical cable under interference with riser

Ships and Offshore Structures, 2018
In consideration of the bend moment and torque, the lumped mass method was derived. Based on the lumped mass method, the umbilical cable was discretised into a lumped mass model and the interferenc...

Stress analysis model for un-bonded umbilical cables

Ocean Systems Engineering, 2013
For the optimization design and strength evaluation of the umbilical cable, the calculation of cross section stress is of great importance and very time consuming. To calculate the cross section stress under combined tension and bending loads, a new integrated analytical model of umbilical cable is presented in this paper.

Finite Element Analysis of Umbilical Cables Anchoring Systems

Volume 5A: Pipelines, Risers, and Subsea Systems, 2017
The connectors on an umbilical system are critical components that are subjected to high tensile loads. To ensure tension resistance to an umbilical cable connection, its structural elements must be properly anchored to the armor pot. One way to provide that connection is the use of the adhesive properties of an epoxy resin.

Electromagnetic Analysis of Submarine Umbilical Cables With Complex Configurations

IEEE Transactions on Magnetics, 2010
These studies present the electromagnetic analyses of different configurations of the so called “Integrated Production Umbilical,” or simply Umbilical Cables. Modern Umbilical Cables can have more than 4 independent 3-phase power circuits as well as steel tubes.
