MQC Stab Plates
An MQC plate is fitted with multiple hydraulic or chemical couplers that enable transfer of a variety of fluids between subsea systems such as trees and manifolds. Manufactured in male and female pairs, each MQC plate is designed specific for the application.
Our MQC plates are fitted with our hydraulic and chemical couplers that enable a compact, lightweight design that is easy to handle and quick to install – reducing subsea operation and installation time.
The Stab Plate is designed to handle rough connection operations, pull-in force and can be installed with an angular misalignment of 20 degrees. The plate can be populated with up to 18 couplers, depending on Coupler size.
With all critical locking system elements and seals located in the flying MQC plate, should any damage occur, the plate can be easily retrieved, repaired or replaced without requiring interfering with the subsea asset. The plate is fitted with a secondary release mechanism for added redundancy.
A full range of parking positions, test and flushing as well as pressure caps, bridging plates and protective covers are available.
