Power System Testing
Robust reLIABLE rEPEATABLE
OneStep Power Solutions develops and provides safe, minimally invasive electrical testing for robust power systems.
Testing can be
completed in 3-5
days on site.
Unique testing solutions reduce risk to personnel and equipment, without changing vessel protections.
Running in closed bus saves 10-16% on fuel costs.
Voltage Dip Ride Through
In order for a Dynamically Positioned vessel to operate safely and efficiently in closed bus, voltage dip ride through must be demonstrated.
Traditionally, voltage dip ride through testing was performed by bolting a short circuit across a busbar on the vessel, causing the vessel’s output voltage to dip, and a very high current to be generated. This current has the potential to damage equipment resulting in downtime and costly repairs.
OneStep Power’s GVRT and ZeroDIP provide a safe alternative voltage dip ride through test. Using OneStep Power’s technologies, the system can induce the voltage response of a short circuit across the whole system for a short period of time, and then return the system to normal.
24V DC cross-connections have been identified by industry stakeholders as being a significant threat to the redundancy of Dynamically Positioned Vessels.
Faults on cross-connected arrangements may propagate beyond the initial fault and cause losses greater than the system design intended.
Currently, OneStep Power is the only provider offering comprehensive cross-connection testing in a single test package.
OneStep Power has developed the DC Cross-connections Short Circuit Under Test, or DCShortCUT. OneStep Power’s DCShortCUT is a testing technology for validating 24V DC cross-connection fault tolerance aboard dynamically positioned vessels.
OneStep Power's Generator Voltage Response Tester (GVRT) allows for all excitation based testing, without the need to change protection system settings, in a controlled, repeatable manner.
OneStep Power's ZeroDIP technology provides minimally invasive testing of closed bus systems for verification of zero-volt ride through.
