Improving the performance and cutting the cost of deploying work-class ROVs – two key priorities for manufacturers and operators of remotely-operated vehicles, both of which DeRegt is addressing with its new cable solutions.
Any object that moves through liquid is subject to hydrodynamic forces. When towing, these forces will exert themselves on ropes and cables, as well as the towed body itself, thereby limiting speed and depth.
The annual Offshore Technology Conference provides a great way to catch up with old and new customers and get a feel for what’s happening in offshore oil & gas. As in other years, we joined forces with other Sercel group companies to show the multidisciplinary fit across the group. As well as DeRegt, we had Metrolog and GRC all on one booth at the heart of the exhibition area. A great position to check the pulse.
Buoyancy is an upward force exerted by a fluid that opposes the weight of an immersed object. If an umbilical cable is too light it will pull an ROV up, which makes piloting fiendishly difficult when manoeuvring through offshore structures.
When working with cables in shallow water, relatively less of the cable will be submerged while the rest of it is wound on a drum on the vessel. In deep water applications, where relatively more of it is deployed, water provides a cooling effect for the cable when it is subjected to electrical currents.
A central component of our cables is a stranded copper wire, which is able to conduct electricity. Around it we extrude a continuous layer of plastic to isolate the copper from its surrounding environment. Twisting this together with other components, forms our custom designed cable.
All change at DeRegt! Following a period of profound organisational transformation for DeRegt, we have now appointed a new managing director. His name is Daniël Ruiter and we had the pleasure of asking him SIX QUESTIONS below. Find out more about our new leader below.
