C. Jim Stewart & Stevenson, Inc. Next to the blowout preventers, the most important component for well control in floating drilling is the system that monitors and controls the behavior of the subsea BOP''s from the drilling rig. From 1955 to 1963, the control system design used in subsea drilling was basically a land rig or "closed-type"

Inspection and Certification of Blowout Preventers - A Recommended Practice (RP) for the Canadian Land-Based Drilling and Well Servicing Industry
A blowout preventer is a large, specialized valve used to seal, control and monitor oil and gas wells. Blowout preventers were developed to cope with extreme erratic pressures and uncontrolled flow ( formation kick) emanating from a well reservoir during drilling. Kicks can lead to a potentially catastrophic event known as a blowout.

Typical BOP bore sizes range from 7-1/16″ to 21-1/4″ for ram preventers and up to 30″ for annular preventers4714.Working pressures range from 2,000 psi to 20,000 psi for ram BOPs and 1,000 psi to 10,000 psi for annular BOPs4714. The pressure rating must exceed the maximum anticipated surface pressure (MASP) the well may encounter.

The blowout preventer (BOP) is one of the most critical safety device in offshore drilling opera-tions. The Macondo incident in the Gulf of Mexico (GoM) in 2010, during which tens of millions of barrels of oil were released into the ocean, was a stark reminder of how catastrophic the results of a BOP malfunction can be.

Our 45,000-ft2 R&D facility features 13 multifunctional test bays and a hyperbaric chamber designed to simulate depths up to 15,000 ft and pressure up to 20,000 psi.
Hydril GK Annular Preventer BOP. The Hydril GK annular blowout preventer (Figure 1A & B) is the most common annular preventer used in drilling rig, particularly in surface stack installations, and is unique in its response to well pressures. Like most other annular preventers, the preventer is closed with about 5,520 kPa (800 psi)
Blowout preventer (BOP) Principle. by Editorial Staff. A blowout preventer (BOP) is a large, specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the uncontrolled release of crude oil and/or natural gas from a well. They are usually installed in stacks of other valves.
U'' Blowout Preventer. Features: U BOP rams are pressure energising. Wellbore pressure acts on the ram to increase the sealing force and to maintain the seal in the event of hydraulic pressure
U'' Blowout Preventer. Features: U BOP rams are pressure energising. Wellbore pressure acts on the ram to increase the sealing force and to maintain the seal in the event of hydraulic pressure loss. The Ram bonnets are opened and closed using hydraulic pressure. Large bore shear bonnets are available for U type BOPs.
Control type: electrically controlled; controlled object: 1; accumulator volume: 25L; system nominal pressure: 21 Mpa,; system pressure regulating range: 0 -14 Mpa; accumulator nitrogen charging pressure: 7 ± 0.7 Mpa; the
ACCUMULATORS OF BOP CONTROL SYSTEM: Check nitrogen precharge in BOP accumulator system every 30 days, Nitrogen precharge should be 1000 psi +/- 10% CAUTION: Use NITROGEN when adding to precharge. Other gases and air may cause fire and/or explosion, ACCUMULATOR RELIEF VALVE: Valve set to relieve at
Blowout Preventers (BOPs) are critical safety devices in the oil and gas industry, designed to prevent the uncontrolled release of crude oil or natural gas
ESD is working on development and qualification of all-electric control of BOPs and a durable rotating control device for managed pressure drilling. Over the past few years, MHWirth has developed new well barrier technology for BOPs, which it has now transferred to ESD in exchange for a 20% share in the company.
Blowout preventer (BOP) is a commonly used safety device in oilfields to seal the wellhead, primarily utilized during operations such as oil testing, well repair, and well completion. Its main function is to close the wellhead and prevent blowout accidents. The BOP combines both full and partial sealing capabilities into one unit, featuring a simple []

Subsea blowout preventer (BOP) is a safety-related instrumented system that is used in underwater oil drilling to prevent the well to blowout. As oil and gas exploration moves into deeper waters and harsher environments, the setbacks related to reliable functioning of the BOP system and its subsystems remain a major concern for
Annular BOP. Annular blowout preventer (Annular BOP) is a special mechanical device used to seal, control, and monitor oil & gas well. Annular BOP is placed on the top of ram preventers. It is called annular due to its structure; it surrounds top of the wellbore in a shape of a ring or an annulus. Ram BOP.
Welcome to Pickett Oilfield''s Blowout Preventers web page. Blowout Preventers otherwise called BOP''s are devices that are used in the drilling industry to seal off and control oil and gas wells. BOP''s are designed to prevent "blowout" which is the unconstrained discharge of oil or gas from the well being drilled.
An accumulator is the storage device for nitrogen pressurized hydraulic fluid and is used in operating the blowout preventers. During the shop inspection, the preventers will be disassembled and inspected for tolerances of wear and tear. Blowout preventer control manifolds must be clearly labeled to indicate that preventers are operated
The basic components of the system include the blowout preventer stack or "BOP" (e.g., annular preventer, ram preventers, spools, internal preventers), the casing head, flow and choke lines and fittings, kill lines and connections, separators, and accumulators ().
83 To obtain a match with real time data, the annular had to be moved to 95% closed starting at 9:43 pm. (95% reflecting the deduced leak condition). The upper annular was found closed at Michoud, and the lower found open. See Appendix C, Condition of BOP as found. 84 BP Report, Appendix Z, Figure 1.
As the gas in the accumulators heat up the pressure should reach the desire pressure within 15 – 30 minutes. If after 30 minutes the desired pressure has not been achieved
