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?
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.
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.
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.
Every cable we design is bent, stretched, rotated and otherwise tortured as part of our verification process. What we do and how? In the first blog of this two-part mini-series, I outlined why mechanical testing can’t be ignored when it comes to designing high performance cables.
There are many aspects to designing a dynamic cable (a cable that is meant to move while in use, as happens when towing, for example, or because of wave motion). Things like torque balancing the cable, the load versus elongation properties, the crush resistance or its fatigue life. But behind every great cable there’s always one thing: a rigorous testing regime that involves checking and describing a cable’s mechanical performance and the applications it can be used for – verification and characterization in industry jargon.
