Every ROV project has its own system requirements. For a fit-for-purpose cable design, these system requirements have to be translated into cable requirements. In other words, the link between system requirements, cable requirements and cable design is crucial for a successful subsea project. 

 

In this blog, we take a look at the system requirements with the greatest impact on cable requirements and the cable design. Read more in this free to download whitepaper.

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 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.

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

May 9, 2019 1:58:34 PM / by Sander van Leeuwen posted in Deep-sea cables, Cable design, Cable solutions

0 Comments

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.

There are many aspects to designing a dynamic cable. For example, a cable can be meant to move while in use, as happens when towing or because of wave motion. Other aspects are things like torque balancing, the load versus elongation properties, the crush resistance and fatigue life.

Like every company, we’re in business to make a profit. But not at any expense. And certainly not at the expense of our employees, assets, the environment and communities. So how do we work? What principles do we live by? We covered them all in our recent Health and Safety Day. See for yourself by watching the video.

An unusual request from 200km off the Norwegian coast- an interview with Aker Solutions

Aker Solutions came to DeRegt with an unusual request. Aker is responsible for the maintenance of a floating concrete tension-leg platform, installed over a subsea template with 56 well slots. The rig is named Heidrun, and produces oil and gas from a depth of 2,300 metres. It is located about 200 km off the middle of the Norwegian coast.

How does DeRegt get cable buoyancy just right?

Feb 22, 2019 12:07:45 PM / by Maurice Corveleijn posted in ROV, ROV Cables, Whitepaper

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.
