Mechanical EQDU

This unit is comprisedof an electro-hydraulic stabplate assembly. The male fixed plate is mounted to the interface between the B.O.P oralternatively the deployment basket. The fixed plate is populated with male hydraulic couplers and electrical connectors, in addition the plate is equipped with coarse and fine alignment.

The free plate is mounted to the breakaway structure or LMRP unit and populated with female hydraulic couplings and electrical connectors which are connected to the work over umbilical via tubetails and cables respectively.

The emergency disconnect package is designed to operate via a controlled breakaway induced by a tugger wire from the surface in the event of an emergency. The platedesign incorporatesprimary (coarse) guidance achieved through the interface to the structure followed with primary (fine) guidance which is designed into the stabplate assembly ensuring fine alignment prior to coupling engagement and locking carried out by an ROV.
