The Hydraulic Power 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 in 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 lift points (swivel rings) 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 part marine epoxy paint system for added harsh environment protection.
