Hydraulic Pumping Unit (HPU)

The Hydraulic Pumping Unit (HPU) is a single skid mounted unit that supplies pressurized hydraulic fluid to various control system components for the safe and reliable operation of the BOP. The HPU is a demand based system (if running is auto mode) that will automatically provide and maintain the required system operating volume and pressure of five-thousand (5,000) psi.

The HPU is designed in compliance with the provisions of API 16D that provide for a combined system to supply a sufficient quantity of hydraulic fluid to charge the entire accumulator system from the pre-charged pressure to the maximum rated operating pressure within fifteen (15) minutes.

The main frame is fully seam welded for maximum durability and strength and comes equipped with four (4) lift points (pad-eyes) for safe handling. A stainless steel, sloped bottom drip pan with valved drains and flush mounted fiberglass grating are also provided to ensure a safe and uncluttered walkway.

In addition, the HPU is supplied with all required suction strainers, block-and-bleed valves, downstream check valves, relief valves, and pulsation dampeners to operate the unit. All main skid structural components are coated with a three (3) part marine epoxy paint system for added harsh environment protection.

Key Features

  • Single skid-mounted unit that supplies pressurized hydraulic fluid to various control system components for the safe and reliable operation of the BOP.
  • The HPU is supplied with all required Suction Strainers, Block and Bleed valves, downstream Check Valves, Relief Valves, and Pulsation Dampeners to operate the unit.
  • The main skid mounted controls consist primarily of control panels mounted on the unit to provide manual operating controls. These include motor controls, motor selector switches and the main pilot pressure isolator panels. Additionally a remote control interface junction box is provided.
  • The HPU can run locally via on-board control panels and instrumentations, or remotely through the DCP, TCP and Master Control Station.
