Subsea Electrical Test Systems (SETS)

The ROV-deployed equipment tests for Insulation Resistance and Continuity Resistance in depths of up to 3,000m, and has been used continually around the world.

Unlike traditional test methods, SETS allows elements of the subsea architecture to be isolated and tested individually. Faults are located rapidly, and an array of tests can be completed and documented in real-time.

When a subsea electrical fault such as Low Insulation Resistance (IR) occurs in electrical connections and umbilicals, finding it from the surface is difficult, when it occurs in deepwater, pinpointing the exact location with the surface mounted instrumentation is even more complex. In the late 90’s IMES developed a Subsea Electrical Test System that allowed localised subsea testing to be applied via an ROV.

Since then continual development has seen SETS’ capability increase to provide a range of tests, live test setup and data feedback allowing real time detailed information on the integrity of cables and umbilicals during installation and  pre-commissioning as well as the traditional fault finding capability.
