In harsh environments, source array cables or umbilicals need to provide maximum tensile strength, damage resistance and conductor count, while minimising outside diameter and weight.
Umbilicals International (UI) has developed lead-in cables which measure 25mm in diameter – a 60% size reduction on previous versions. In addition, UI has reduced the 67mm GS standard analogue AGU by 80%, while providing increased towing loads.
The development of reliable in-water air distribution manifolds and gun control systems have allowed this size reduction. UI’s ability to manufacture key components, cables, pressure hoses and connectors has optimised the design and manufacture, while offering a single point of responsibility.
The Digital Age
As new source configurations and techniques push the limits in the analogue domain, digital source controllers have been developed to improve the timing accuracy of arrays, while allowing for increases in array setbacks. Data collection from other sensors within the array now drives the telemetry requirements for these digital controllers.
UI has met the challenges posed by harsh environments on umbilical systems by designing bespoke products with improved connector designs. This allows for constant and consistent telemetry in high shock environments.
