Viper Subsea has added to its already impressive and innovative product portfolio with the introduction of V-SUPPLY, a topsides Electrical Power Module, which as well as providing a stable and reliable source of electrical power to subsea equipment, 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 the 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 Subsea.

Speaking about the new technology, Neil Douglas, Managing Director of Viper Subsea said "The V-SUPPLY will offer our clients the opportunity to upgrade their topsides located subsea power delivery equipment in a cost effective way whilst at the same time integrating the latest monitoring technology. Offering operators remote access to full electrical performance monitoring delivers obvious cost savings and operator safety improvements.

"This is especially important at this time as operators are working in an increasingly difficult marketplace and are under pressure to ensure continuous production while minimising disruption.

V-SUPPLY is unique in its capability to monitor the condition of both the electrical conductors and cable insulation on a live system, detecting both transient and permanent problems in the cables and the umbilical.
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 the use of a software licence. V-SUPPLY also incorporates Spread Spectrum Time Domain Reflectometry (SSTDR) for continuous integrity monitoring of electrical conductors. SSTDR is especially targeted at integrity monitoring of copper conductors in dynamic umbilicals where the risk of faults is at its highest.

V-SUPPLY is designed to be compatible with both brownfield installations and new 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.
