HH System

Hydraulic-over-Hydraulic (H/H)

  • Utilizes a regulated hydraulic pressure source (taken directly from the manifold pressure regulator), a hydraulic remote valve manifold, interconnect hoses and hydraulic actuators to provide remote function of the BOP/HCR control valves and/or pressure regulators in the Control Manifold.
  • The Hydraulic Remote Station will include a master supply valve and the required number of remote function (manipulator) valves for each BOP/HCR control valve and hydraulic-operated failsafe regulator adjustment in the Control Manifold. This remote system may also include gauges to provide indication for Accumulator, Manifold and/or Annular Pressures.
  • Each BOP/HCR control valve in the Control Manifold will include a hydraulic-operated actuator to provide remote function of each control valve.
  • One or both pressure regulating valves may include a hydraulic-operated failsafe adjustment for remote adjustment of these pressure regulator(s).
