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.

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.

Accumulated Plastic Strain Evaluation of Steel Tube for Umbilical Cables

Volume 3: Pipeline and Riser Technology; Ocean Space Utilization, 2008
This paper presents the tests performed for the qualification of the level of accumulated plastic strain (APS) to be respected by manufacturing and installation of SAF 2507 steel tube umbilicals. The manufacturing and installation processes for steel tube umbilicals are carried out through repetitive cycles of coiling and uncoiling the tubes or ...

An Integrated Environment for Design and Analysis of Umbilical Cables

Volume 5A: Pipelines, Risers, and Subsea Systems, 2017
The 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.

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

Choice of Umbilical Cable for Submersibles - Footprint Optimization

Offshore Technology Conference, 1982
Abstract The limits of the operational area of a ROV (Remotely Operated Vehicle) are calculated when it is working at a certain water depth. The boundary of the operational area is called the footprint and is depending on the thrust which can be delivered by the submersible, the current velocity, the water depth and
