Independent Cable Testing

Tension: Break strength, proof load certification, load vs. elongation, fatigue and retirement criteria, dynamic load simulation, cable qualification and pre-tensioning.

Measurement and Analysis: Tension vs. torque or rotation, torque-balance verification, non-rotating and twist resistance testing, torque-restraint validation, conductor and optical fiber performance monitoring.

Bending: Static and dynamic bending, handling system simulation, fairing and hardware qualification, wet/dry fatigue performance, jacket abrasion, and tow point dynamics.

Hydrostatic Pressure: At-depth pressure simulation with verification of seal, and electrical and optical performance.

PMI can test raw or terminated cables, unterminated cables, and complete cable assemblies, etc. We handle cables with steel or synthetic strength members, as well as those without any strength member.

PMI most commonly tests cables used in underwater applications, but our capabilities are not limited to these environments. We are happy to review and discuss any cable to determine appropriate testing options.

The required cable length will depend on the type of test being performed.

A drawing or sample of the cable is most helpful, allowing us to review the cable construction and determine the best testing approach.

Yes. To help us provide an accurate quote, please provide any available details, such as strength member type, core construction, outer jacket material, outer armor, outside diameter, rated break strength, rated working load, and any other specifications.

PMI customizes each test to the needs of your project. Understanding how the cable will be deployed and used helps us develop an effective test plan. We can create a plan with you or review any existing plans you have, using our standard process as a foundation.

Key factors include the type of testing, number of cycles, duration or hold times, measurement (electric, optic, voltage level, frequency, wavelength, etc.), whether measurements are taken during or before/after testing, and applicable specifications. PMI will review all details to ensure feasibility.

Yes, PMI conducts qualification testing and acceptance testing on previously qualified designs.

Yes, PMI can terminate the cable and install connectors before testing.

Yes. After reviewing, PMI can often use customer-provided test leads and equipment, such as mate connectors, special hardware adaptors, pressure caps, etc.

The lead time will depend on the type of test, complexity, quantity, requirements, and any equipment modifications needed.
