CROss-connections

Control system cross-connections have been identified by industry stakeholders as being a significant threat to the redundancy of Dynamically Positioned Vessels.
A fault downstream of cross-connected power supplies, when propagated up to the power supplies, is considered to threaten both the power supplies. If the problem propagates through the power supplies to their source, all other consumers fed by the same source are also at risk. As such, in a cross-connection arrangement, a fault on one set of supplies could cause the loss of multiple sections of the vessel. With the advent of high reliability power supplies and electronic circuit protection devices, the risk of faults propagating through a DC cross-connection has decreased significantly.
How can vessel owners provide assurance to clients and stakeholders that the risk has been sufficiently mitigated through equipment selection and design?
OneStep Power has developed the Cross-connection Short Circuit Under Test, or ShortCUT, the first comprehensive cross-connection testing solution.
The ShortCUT Series provides safe and reliable testing, which can be repeated on a regular basis.
ShortCut Series

Trusted by major DP assurance providers and charterers
Since 2020, OneStep Power’s ShortCUT technologies have been the proven way for DP shuttle tankers, drillships and offshore support vessels to quickly validate their safety-critical cross-connection designs and meet contracting deadlines.
OneStep Power’s ShortCUT technologies let you rapidly validate that your DP vessel's cross-connections won't propagate faults. Testing can take less than an hour per cross-connection and can be scheduled for no downtime.
