For the design and construction of a new subsea trenching vehicle, named “Swordfish”, Osbit Ltd. (UK) was in need of a subsea trencher lift umbilical, used for launch and recovery of a subsea asset and transmission of electrical power and fibre optic communications. In their search, they came into contact with DeRegt.
Improving the performance and cutting the cost of deploying work-class ROVs – two key priorities for manufacturers and operators of remotely-operated vehicles, both of which DeRegt is addressing with its new cable solutions.
DeRegt works with each individual client to provide the perfect cable solution for their specific requirements. Each cable system by DeRegt is custom-made and this does not only apply to the cables themselves, but the terminations as well.
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.
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.
Right now, more than thousand work-class ROVs worldwide are doing their work underwater. They’re used for various tasks, such as repairs and maintenance, trench digging and drilling. Because these activities are taking place at increasingly great depths, ROV manufacturers face the challenge of coming up with innovative solutions to make sure the lifetime of these cables is sufficient. To extend this lifetime, there are a couple of things to be considered.
This is important, as cables are one of the most important parts of a system in a lot of industrial applications. But how do you make sure there's less failure and a better performance, while saving on costs? Let's dive deeper into that.
