Combined Power, Gas and Communication Umbilical Cables

OCEANS '76, 1976
The 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 ...

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.

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.

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

Passive damping to attenuate snap loading on a ROV umbilical cable

Proceedings of OCEANS '93, 1993
Summary form only given. Snap loading of the umbilical cable connecting a ship to a remotely operated vehicle (ROV) and its cage is a major problem when the ROV system is operating in rough sea conditions. Snap loading is the instantaneous, high magnitude, tensile loading of a cable.

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 ...

Design and installation of subsea cable, pipeline and umbilical crossing interfaces

Engineering Failure Analysis, 2017
Abstract Deterioration of subsea cable, pipeline and umbilical crossings often occur due to relative movement between the crossing members. Any crossing design should aim to achieve a sound, fit for purpose solution that will be maintenance free over the crossing life.
