The v-lock hydraulic stabplate has been designed to meet the needs of the subsea industry for the foreseable future.

Viper Subsea has developed a family of hydraulic stab plates and associated products. The stab plate family has been given the trade name of V-LOCK  and with the technical specifications having been driven by our clients, the V-LOCK family has been designed to meet the needs of the subsea industry for the foreseeable future.

The stabplate is designed for operation by ROV and offers market leading technical performance in terms of ROV interfaces, pressure ratings, weight and secondary release. The V-LOCK plate comes in three separate sizes, to accommodate up to 8, 16 and 28 hydraulic couplings and is suitable for use at depths down to 4000m. The plate is designed around the use of National Coupling Company’s hydraulic couplers, offering a range of coupler sizes, working pressures and seal types. As well as the basic ‘fixed’ and ‘flying’ plates, the normal range of parking positions, protective covers, test and flushing plates are offered.

The plate has a novel actuation mechanism which results in a highly reliable solution that is physically smaller and lighter than traditional stabplate designs. This coupled with our incredible make-up misalignment capability, ensures that the V-LOCK can be installed with reduced ROV intervention times.

V-LOCK also benefits from a secondary release that does not rely on any form of shearing mechanism.

Viper Subsea have partnered with ‘best in class’ manufacturing and jumper manufacturers to be able to offer not only stab plates, but complete Hydraulic Flying Lead assemblies.

The V-LOCK stabplate has successfully undergone a rigorous qualification testing programme, during which exceptional performance and functionality was demonstrated.
