Choice of Umbilical Cable for Submersibles - Footprint Optimization
Offshore Technology Conference, 1982Abstract 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, 1993Summary 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, 2008This 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, 2017Abstract 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.

A Study on the Dynamics of Marine Umbilical Cable for Underwater Vehicle
2016The dynamics of underwater umbilical cable (UC) for underwater vehicle (UV) are an important in ocean engineering. These UC are widely used in the ocean environment for signal and power transmission application. To apply the cable to power and data transmission for small UV, the dynamics of the UC are studied in the paper.

Precise Stochastic Fatigue Life Assessment of Umbilicals and Power Cables
Offshore Technology ConferenceAbstract Increasing activity within offshore wind energy and related installations has raised the focus on the integrity and fatigue life of power cables and umbilicals. A limiting factor for assessing fatigue life has been the lack of efficient and precise computational tools that are not overly conservative.
