Electrical Test Systems for the Subsea Sector

Subsea electrical interconnect systems often carry high current and high voltage, often deployed to extreme depths where failure of such components is catastrophic and have massive financial consequences.

As a specialist in high voltage and high current test systems, MK Test has delivered specialist test equipment to some of the world’s leading subsea interconnect manufacturers including TE Seacon and ThyssenKrupp.

“Our test systems are compliant to SEPS and NORSOK standards.”

Subsea Applications

Cable Harness

Wherever a cable harness is being assembled it is essential that the harness or loom is tested for build and or material defects. Tests typically include continuity resistance, short circuit failure, high voltage insulation resistance, AC dielectric or HiPot test and capacitance measurement.


When a wiring harness is fitted into a major component, such as a train carriage, aircraft wing or power panel, MK Test equipment is used to ensure that the installation has not impacted negatively on the performance and integrity of the harness components, wiring and connectors. Installed harnesses and components are tested in situ, testing continuity resistance, short circuit failures, high voltage insulation resistance and HiPot dielectric strength, and function testing of active components such as actuators, relays, solenoids and lamps .

Subsea Interconnect Systems

With its ability to perform high voltage Insulation testing at up to 15000VDC and measure Insulation Resistance up to terra ohms, MK Test’s specific subsea interconnect test systems are gaining fast adoption with the offshore sector. Fixing poor connections on the seabed is an expensive business, so testing is a vital part of the preparation of subsea electrical systems.  MK Test’s subsea test systems offer testing in compliance with SEPS SP-1001 plus relevant NORSOK and IEEE test standards.
