Why is it important to involve your cable supplier early in the development of your new product or equipment? At DeRegt we often see customers who have succeeded in developing a great system, but who simply forget to think of the cables involved, or underestimate the complexity of them. You can have two fantastic pieces of equipment, but if you don’t have the right cable to connect them, they are likely to be worthless. Involving your cable supplier at an early stage of the project offers three key benefits:

DeRegt works with each individual client to provide the perfect cable solution for their specific requirements. Each cable system by DeRegt is custom-made and this does not only apply to the cables themselves, but the terminations as well. DeRegt is able to design the termination to adapt to specific circumstances and to think outside the box to find the right solution for every situation. From deep undersea to high in the sky, terminations can be grouped into a few types which share similar features.

How does DeRegt get cable buoyancy just right?

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. If the tether is too heavy it will push the ROV down making delicate work impossible. So how do we make sure we get it just right? Find out how we are able to test down to a single gram, up to 200 bar.

How do we prevent dangerous overheating in your cable?

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. In contrast, in the shallow water applications, layers of cable are spooled on a drum on the vessel and these layers are unable to benefit from the cooling effect. Eventually, the heat caused by the electric current flowing through the cable builds up.

Driven by solutions: Phil Roscoe on the new future-proof extrusion room

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.

The plastic has to be a good insulator and thick enough to prevent the copper from shorting to the outside world. Many of our cables operate in deepwater under high pressure, so we need to make sure that our insulation is sturdy enough to keep the water out. Contamination in the plastic will cause the insulation to deteriorate over time and eventually fail.

Cables are one of the most important parts of a system in different industrial applications. It’s essential that work-class ROV operators purchase these cables from a high-quality cable manufacturer. While purchasing them from a renowned manufacturer is the first step towards extending the lifetime of your cables, it’s not enough on its own.
