Independent Testing Services for Cable, Hardware, and Devices

Ensure Survivability of
Your Cable System at Sea

Typical at-sea conditions can cause catastrophic failures to your cable system. Our testing facility is fully equipped to simulate service conditions experienced by underwater cable systems and devices. Performing extensive laboratory testing can help you identify potential problems prior to use.

PMI’s specialty is to provide insight into the interaction between the strength member and attached hardware or the complete cable assembly. We will test all or any part of your project:
