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 ...
