Ensure Survivability of Your System at Sea

PMI is capable and willing to take on new challenges to simulate service conditions experienced by underwater cable systems and devices. Our specialty is to provide insight with respect to the interaction between the strength member and attached hardware or the complete cable assembly. PMI will test all or any part of your project:

  • Raw Cable (Metallic and Synthetic Strength Members)
  • Rope and Hose Assemblies
  • Cable Assemblies, Cable Hardware, Terminations and More

Typical at-sea conditions can cause catastrophic failures to your system. Our facility can assist you to identify potential problems prior to use by performing extensive laboratory testing.

Our 100 kip tension test system includes MTS FlexTest® 40 controller with MTS TestSuite™ Multipurpose Elite software and integrated data acquisition. This enables us to easily create, edit and run complex tests with much greater flexibility than ever before as well as capturing the test data seamlessly. Test configurations can be saved and reused. It also provides real-time reporting so that at the completion of a test, the data can be plotted and reported immediately.
