As renewable energy systems move offshore, power transmission becomes one of the most fascinating engineering challenges of our time. From floating wind farms to wave energy converters, the demand for dynamic subsea umbilicals, is growing rapidly.
The energy world is changing fast, and engineers are right in the middle of it. As global demand for clean, affordable power rises, industries that rely on stable energy supply face a new challenge: how to expand renewables while keeping the planet cool. To make that possible, governments and energy companies are investing heavily in New Energy technologies. From offshore wind to geothermal and carbon capture. And at the foundation of many of these developments lies one crucial capability: accurate marine seismic surveying.
Offshore wind and onshore solar have changed the energy landscape. But they can’t do it all. As the push toward net-zero 2050 accelerates, engineers are looking deeper, quite literally, for consistent, round-the-clock renewable power. The ocean holds the answer. Tidal and wave energy are now stepping into the commercial spotlight, while subsea cables and connectors evolve to handle higher voltages, smarter networks, and longer lifespans. In our trend report (longread: 30 minutes) you can download at the bottom of this blog post, we explore the engineering breakthroughs making marine energy the missing piece in the global clean-power grid. And what it means for cable design, deployment, and reliability. But first, in just 2-3 minutes, let's find out if the trend report is worth your energy and time...
Every sonar engineer knows that signal clarity begins with the cable. But in naval defense, not all sonar systems are created equal. And neither are their cables.
At DeRegt, we’ve spent decades helping navies and defense engineers turn hydrodynamic challenges into predictable performance. In this article, we explore two main sonar architectures: Towed Array Sonar and Variable Depth Sonar. And how depth, buoyancy, and cable mechanics reshape what’s possible underwater. Because sometimes, being able to detect an enemy is just a matter of a few grams per meter, or the right cable design.
Subsea operations are expanding rapidly, from offshore energy and marine science to defense and security. No matter the mission, one component often determines whether a project succeeds or fails: the subsea cable. Far more than just a connection, it transmits power, data, and control, while also carrying mechanical loads in harsh and unpredictable environments. Selecting the right cable is not simply a technical decision; it is a strategic one.

If you’ve ever worked on a subsea project, you’ve probably seen it happen: Two world-class pieces of technology, flawlessly designed, but they never perform as expected once deployed. Why? Often, the weakest link isn’t software, electronics, or hydraulics. It’s the cable termination. That small interface between the umbilical and the equipment carries everything: power, data, tension, and trust. And when it’s not engineered to the same standard as the rest of the system, the deep sea has a way of reminding you. Fast.
Why is it important to involve your cable supplier early in developing your new product or equipment? At DeRegt, we often see customers who have succeeded in developing an excellent Sonar or ROV system but forget to think of the cables involved or underestimate their complexity. Two brilliant systems without the right umbilical are just isolated hardware. The cable is not a connector — it’s the critical pathway that enables data, energy, and control to coexist as one functional system.
Whether you’re designing subsea systems, modeling material behavior, or researching extreme environments, this is where physics, materials science, and real-world engineering meet. In this 49-minute masterclass, DeRegt’s R&D Manager Sander van Leeuwen reveals what truly determines the performance, safety, and lifespan of deep-sea ROV umbilicals. And how the same principles apply to any complex engineered system operating under pressure, tension, and time. Your time is precious, so first we'll share with you the key subjects that Sander will be talking about.
