Our customers define the system requirements. DeRegt translates these system requirements into cable requirements and eventually into fit-for-purpose designs. This white paper looks at the link between
the system requirements, cable requirements and cable designs. The focus is on dynamic cables for offshore applications (e.g. cables for ROVs, towed array systems, wave energy systems, deep sea mining umbilicals or BOP cables).

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.
