Viper Subsea has added to its product portfolio with the introduction of V-SUPPLY, a topsides electrical power module, which as well as providing a source of electrical power to subsea equipment, incorporates 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. V-SUPPLY provides control and monitoring technology, and is designed to deliver improved safety performance and cost savings for operators as it provides remote umbilical testing without the need for technicians to be mobilized offshore. The remote testing capability is a novel technology proprietary to Viper Subsea.
“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,” said Neil Douglas, managing director, Viper Subsea. “Offering operators remote access to full electrical performance monitoring delivers obvious cost savings and operator safety improvements.
V-SUPPLY monitors 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. The technology incorporates the V-LIM, Line Integrity Monitoring functionality, and the proprietary Insulation Resistance recovery technique of V-LIFE, which can be easily activated through the use of a software license. 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.
In addition, 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.
