All you need to know about the design considerations for your perfect cable solution

What is the link between system requirements, cable requirements and cable designs?

You may know what your perfect cable solution should look like. But what are the most important design considerations? In this white paper our expert explains all you need to know about the link between system requirements, cable requirements and cable designs.

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.

However, these forces can be altered by changing the geometry of the cable. This white paper offers a brief introduction into these “fairing” methods, which allow for deeper towing at higher speeds.

We design every cable termination specifically for each project. This means we always try to find the perfect solution for the connection between the cable and the client interfaces. The clearer you can get the termination specification, the fewer iterations the design will need, and the more quickly it can be achieved.  Below, you will find 10 useful pointers for writing a great termination specification. 

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:

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. 

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.
