Unit-mounted Hydraulic Control Manifolds HYDRAULIC CONTROL MANIFOLDS The Hydraulic Control Manifold provides safe, dependable operation for control of the BOP stack utilizing subplate mounted control valves. Separate circuits provide independent pressure regulation and control for the annular preventer and for the ram and gate valve functions. The manifold functions are supplied

through the 3 inch machined manifold rated for 5,000 PSI WP The internal override feature of the Regulator permits immediate 3,000 PSI accumulator pressure to the manifold, doubling the closing force on the rams in event of an emergency. The manifold directional control valves and outlet piping to the preventers are rated for 5,000 PSI working pressure. These manifolds are available with rugged, mud pump style or glycerin-filled, panel mounted, direct

reading gauges indicating manifold re g u l a t e d , a n n u l a r re g u l a t e d a n d accumulator pressures. The manifold selected with either the manifold regulator internal override or bypass valve can be supplied with 5,000 PSI pressure for testing or extreme well control problem when air pumps assemblies with hydro-pneumatic valve by passes are selected.

Air Pump Assemblies Air operated pump modules are used to provide high pressure fluid energy to charge the accumulators and operate the BOP stack functions. When used in conjunction with electric pump modules, compliance is met with the requirements of API Specification 16D Air pump modules provide various options to meet

your exact specifications and economic requirements.

hydraulic system operating pressure of 3,000 PSI.

The design performance ratios offered by Sara are engineered so that the rig air supply system is not overburdened and, in the event of low rig air pressure, the air operated pumps can still attain the

The air pump modules have a hydropneumatic pressure switch which is set to stop the pumps at 2,900 PSI. The pumps will automatically start again when the system pressure falls approximately 400 PSI.

Electric Pump Assemblies The electric motor driven pump module is the primary source for generating the hydraulic energy which is stored in the accumulators to operate the BOP stack functions. These pumps are offered in a variety of options and operating voltages to meet the specific requirements prescribed in API Specifications 16D.

manufactured by Sara are designed for operation in Class 1, Group D, Division-1 hazardous locations. Only electrical components that meet NEMA, NEC and UL specifications are selected for these applications.

maintaining pressure in the accumulators from 1,500 to 1,800 PSI above the minimum operating pressure of 1,200 PSI. Electric pump modules are sized to close the specific annular presenter in use by the customer and to open the hydraulicactuated choke valve within two minutes (with the accumulators blocked) or to charge the accumulators from minimum pressure to 3,000 PSI in fifteen (15) minutes or less.

The electric pump modules are set to automatically stop when system pressure reaches 3,000 PSI and start again when system pressure drops to 2,700 PSI,

Remote control panels allow the main accumulator unit with its hydraulic control manifold to be located at a safe distance from the rig floor and yet provides full control of the BOP stack, easily accessible to the driller. Every rig is required to have at least one remote control panel in order to comply with API specification 16D. A second remote panel is recommended near the escape exit or in a safe location where the BOP stack can be controlled should the drilling crew have

to evacuate the drill floor.

the manifold control valve positions.

Remote control panels located at the driller's station should be capable of operating every BOP stack function, controlling regulated pressure of the annular preventer for stripping operations and also capable of immediately switching from regulated pressure to full accumulator pressure to the ram preventers should additional closing force be required during extreme well control problems. The driller's remote panel should include gauges or meters for remote indication of the various operating pressures and open/close status of

Air purge and explosion-proof panels meet NEC Class 1, Group D, Division 1 requirements for hazardous environments. PLC based panels are equipped with a color touch screen for display and are available in wireless configurations not requiring air hose or electric cable. Specifications for various standard models shown. Other models are available upon request.
