Reliable Subsea Cable & Interconnect Solutions for Critical Offshore Applications

You won’t find subsea interconnect solutions on land. They live underwater, providing power and connectivity to mission critical systems all over the world despite intense hydrostatic pressure and limited maintenance opportunities.

Whether you’re designing for offshore oil and gas production systems, oceanographic instrumentation and sensors, naval defense platforms, automated aquaculture technology, or cutting edge ROV and AUV technology, subsea cables are the unsung heroes that make subsea connectivity possible. Deploying thousands of feet underwater leaves little room for failure. Your systems have to work.

Aptiv is a leading subsea cable manufacturer specializing in custom subsea power cables, signal cables, and hybrid cable assemblies. Our engineers and technical team understand the unique challenges associated with underwater applications and design subsea cable systems to perform for years of continuous deployment.

Subsea Cable Assemblies Built for Reliability

Cables used for subsea connectivity are engineered differently than cables used for industrial applications on land. High pressure, temperature variances, mechanical flexing, saltwater, and limited maintenance windows are just a few of the things subsea power cables and control cables have to withstand.

For many subsea applications, the cables don’t just deliver power, they bring high-speed data connections and onboard signal conditioning to remote systems. That means the subsea interconnect you choose will determine the performance of your entire system.

Providing that kind of reliability means understanding your application from more than just an electrical standpoint. Subsea cables used for fixed seabed installations have different requirements than cables used for towing applications such as ROV tether cables.

Our team at Aptiv works with customers to deconstruct the unique environmental and mechanical demands of their application to design subsea cables that are built for performance.

Built to Last: Subsea Cable Systems from Aptiv

When your cables are thousands of feet underwater, one unplanned dive can mean lost production, canceled research operations or interrupted defense activities. Connectivity suddenly stops when subsea cables stop working. That’s why cables used for subsea applications are designed to do more than meet performance requirements at the time of installation. They’re built to provide consistent electrical and mechanical performance year after year in some of the harshest conditions on earth.

Subsea cable reliability starts with the right combination of components working together. Key factors include:

• Conductors – Wire material and geometry directly impacts the electrical performance of your cable under pressure
• Insulation – Insulation materials protect conductors from water exposure and chemical breakdown
• Waterblocking - Helps subsea cable maintain connectivity even with extreme hydrostatic pressure
• Shielding – Maintains signal performance in electrically noisy environments
• Armor and Jacketing – Cable subsystems designed to mitigate abrasion and metal fatigue

With years of experience designing custom connectivity solutions for extreme environment applications, our engineers know how each material and cable construction technique can help (or harm) long-term performance.
