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:

How to make a light-weight electro/optical umbilical?

The newly developed Sonic Wireline Operated Remote Drill (SWORD) is a system designed to collect samples and geotechnical data from the seabed. The cable needs to combine electro/optic components with a high tensile light-weight strength member, taking into account the rules around rope hoisting/lifting applications. Where conventional steel would be too heavy to cope with the system requirements, the optimal configured strength-member is able to withstand the high tension, at a lower self-weight. This white paper explains how De Regt designed, manufactured and tested a unique cable solution with a strength member made of 8 (!) layers of aramid wires. This is a world-first.

The EU aims to reduce dependency on imports of raw materials. Large quantities of raw materials can be found in deep sea Polymetallic Nodules. Polymetallic Nodules contain relatively high concentrations of Nickel, Copper and Cobalt. Cobalt is especially valuable to harvest since it is used in batteries for electric cars. Nodules occur at any depth, but the highest abundance has been found between 4,000 and 6,000m. How do you harvest these nodules at such a large depth?DeRegt was asked to join an EU funded consortium of 14 companies. Industry, research institutes and service companies across seven different countries joined hands to solve the question on how to harvest them, avoiding serious harm and minimizing the environmental risks.
