T81 Operation of Double Ram gate BOP
A double ram blowout preventer (BOPs) is a critical piece of safety wellhead equipment used in the oil and gas drilling rigs industry to prevent the uncontrolled release of hydrocarbons from a well during drilling well , completion, or intervention operations. Double ram BOPs are designed with two sets of sealing rams that can close around the drill pipe or tubing to provide a secure seal and prevent the flow of high pressure fluids mud from the wellbore.
Manual operation of a double ram BOP involves using hydraulic controls and manual handles to open and close the rams. manual lock and hydraulic lock,
Here are the general steps for manually operating a double ram BOP:
Safety Precautions: Before you begin any manual operations, ensure that all safety procedures and guidelines are followed. This includes wearing appropriate personal protective equipment (PPE) and conducting a safety briefing.
Inspect test the BOP: Visually inspect the double ram BOP to ensure that it is in good working condition. Check for any visible damage or wear.
Hydraulic Control System koomey unit: Locate the hydraulic control system for the BOP. This system is typically located near the wellhead or on the drilling rig. Ensure that the hydraulic system is pressurized and functioning correctly.
Ram Position: Determine the current position of the rams (open or closed). If the rams are closed, you may need to open them to allow for operations such as pipe insertion or removal.
Ram Operation: Depending on the design of the BOP and the control system in use, you will have manual handles or levers to control the opening and closing of the rams. Follow these steps:
To Open Rams: Turn the handle or lever in the appropriate direction to open the rams. This will create an opening through which you can insert or remove the pipe.
To Close Rams: Turn the handle or lever in the opposite direction to close the rams. This will create a seal around the pipe.
Pressure Monitoring: Continuously monitor pressure gauges and indicators to ensure that the BOP is holding pressure as expected. If there is any drop in pressure, it could indicate a leak or a problem with the seals.
Pipe Handling: If you are using the BOP to control the flow of fluids during drilling or well control operations, carefully insert or remove the pipe through the the same size of rams as needed.
Emergency Shutdown: In case of an emergency or uncontrolled flow of hydrocarbons, be prepared to quickly close the pipe rams and blind ram to regain control of the well.very urgent,they will use the blind shear ram assembly to cut the drill pipe or tubing.
Post-Operation Inspection: After completing the necessary operations, inspect the BOP again to ensure that it is in good condition and that there are no signs of damage or leaks.
Record Keeping: Maintain detailed records of all BOP operations, including the times and reasons for opening and closing the rams.hong long time to close the BOP in the kommey unit control.
It's essential to have well-trained personnel who are familiar with the specific BOP system and its operation procedures to ensure safe and effective manual operation of a double ram BOP. Additionally, always follow the guidelines and procedures provided by the equipment manufacturer and the relevant regulatory authorities.
