V-SUPPLY Electrical Power Module.

V-SUPPLY is unique in enabling subsea electrical circuits to be tested with no wiring disconnects.

V-SUPPLY provides a stable and reliable source of electrical power to subsea equipment and incorporates state-of-the-art monitoring technology.

The development of the V-SUPPLY has been driven by a growing obsolescence issue that is being faced by a number of operators and the need for more advanced condition monitoring of subsea electrical systems. Not only does V-SUPPLY provide the latest control and monitoring technology, it will deliver improved safety performance and cost savings for operators as it provides remote umbilical testing without the need for technicians to be mobilised offshore. The remote testing capability is a novel technology proprietary to Viper Innovations.

V-SUPPLY incorporates the V-LIM line integrity monitoring functionality, and also the proprietary Insulation Resistance recovery technique of V-LIFE, which can be easily activated through a software licence.

V-SUPPLY is designed to be compatible with both brownfield installations and greenfield developments and offers a touch screen display as a user interface. Optional electrical supply conditioning provides precise voltage control and variable frequency of output supply. With administrator rights, the onshore engineer can remotely change the subsea supplies and monitor parameters such as transient faults and harmonic distortion.
