FAQs

What role do subsea cables play in seismic data acquisition?

In seismic exploration, subsea cables connect thousands of sensors and transport massive volumes of data to the surface. Cable performance directly affects data quality and reliability of surveys.

What are the benefits of dynamic cables in offshore wind, wave energy and tidal energy?

Most subsea power cables in offshore energy are static, installed permanently on the seabed where they are buried or anchored. With new technologies such as floating wind turbines and wave energy converters, however, there is a growing need for dynamic cables that operate vertically in the water column.

Dynamic cables must withstand continuous motion caused by waves, currents, and tidal forces. This means they are exposed to millions of bending cycles and dynamic loads throughout their lifetime. Unlike standard static cables, they must be specially engineered to resist fatigue, maintain performance, and ensure safe power and data transmission under harsh offshore conditions.

The benefits of dynamic cables include:

Enabling floating renewable energy solutions that cannot be supported by static cabling.
Long-term reliability under constant mechanical stress, reducing the risk of failure.
Supporting energy innovation by making new technologies like wave and tidal converters commercially viable.

DeRegt specializes in designing and manufacturing dynamic subsea cables that integrate power, data, and strength elements. By optimizing each cable for its specific marine environment, we help offshore energy operators achieve safe, reliable, and cost-effective renewable energy production.

How does DeRegt ensure long lifespan and safety in renewables?

Offshore renewable energy projects demand cables that can perform reliably for decades in harsh marine conditions. At DeRegt, we ensure long lifespan and operational safety through a combination of engineering expertise, material selection, and lifecycle support:

Advanced material selection. We use tailored combinations of copper alloys for power and signal transmission, fiber optics for data, and strength members such as steel or synthetics (e.g., Kevlar). Protective polymers and insulation are chosen to resist seawater, UV, and chemical exposure.
Design for dynamic loads. Renewable applications such as wave and tidal energy expose cables to millions of bending cycles. Our designs account for these dynamic stresses to minimize fatigue and extend service life.
Extensive testing and qualification. Every cable undergoes Factory Acceptance Testing (FAT) for its electrical, optical, and mechanical properties. We also perform qualification testing to validate performance under simulated offshore conditions.
Lifecycle support. Our field service teams provide inspection, maintenance, and repair in the field, helping operators safeguard performance and extend cable life beyond initial design expectations.

By combining specialist engineering with hands-on service, DeRegt delivers renewable energy cables that are safe, reliable, and built to last in the toughest offshore environments.

What is the difference between static and dynamic subsea cables in offshore energy?

Static subsea cables are installed on the seabed, either buried or anchored, where they remain fixed for their entire lifetime. These cables are typically used to transmit power from fixed offshore wind turbines or other stationary installations. Their design focuses on long-term stability, protection against seabed conditions, and efficient power transmission.

Dynamic subsea cables, on the other hand, are designed to operate in the water column, where they are constantly exposed to movement caused by waves, currents, and tidal forces. They must endure millions of bending cycles and high mechanical stresses over decades of operation. This requires specialized designs and materials that can handle fatigue, maintain signal and power integrity, and ensure safety under harsh offshore conditions.

With the rise of floating wind farms and wave/tidal energy converters, dynamic cables are becoming a key enabler of next-generation renewable energy solutions. DeRegt specializes in tailored dynamic cable systems that integrate power, data, and strength elements to provide reliable, long-term performance in demanding environments.

What services does DeRegt provide for subsea energy cables?

DeRegt offers a full range of services across the entire cable lifecycle, ensuring offshore energy operators can rely on safe and efficient performance over many years:

Cable termination & integration. Delivering complete, ready-to-use solutions including customized terminations and assemblies.
Testing & qualification. Every cable undergoes Factory Acceptance Testing (FAT) for electrical, optical, and mechanical properties. We also perform qualification testing and analysis to validate performance in demanding offshore conditions.
Global field service. Our specialists provide on-site support for installation, inspection, maintenance, and repair. This is particularly critical in the seismic market, where extensive field service ensures that long and complex sensor arrays remain operational throughout data acquisition campaigns.
Lifecycle support. Through periodic inspections, testing, and maintenance, our field service teams help operators assess cable condition, detect potential issues early, and ensure safe long-term operation. This proactive approach reduces downtime, extends lifespan, and safeguards critical offshore missions.

With this combination of technical expertise and hands-on global support, DeRegt ensures subsea cables remain in peak condition from deployment to decommissioning.
