Hot tapping is a process used in the oil and gas industry to tap into pipelines while they are still in service. This technique enables the installation of new piping, valves, and other equipment without the need to shut down the entire pipeline. To ensure that this procedure is executed safely and correctly, a detailed method statement is required.

The first step in the hot tapping method statement is to identify the pipeline to be tapped and the location where the hot tap will be made. This involves verifying the size, material, and operating conditions of the pipeline, as well as checking the surrounding area for any potential hazards.

Next, the hot tapping machine and associated equipment must be selected and tested to ensure that they are capable of handling the specific pipeline and operating conditions. This includes verifying the pressure and temperature ratings of the equipment and ensuring that all safety features are in place and functioning correctly.

Before the hot tap is made, the pipeline must be purged of any contaminants or debris that could compromise the integrity of the tapping operation. This typically involves the use of a pig or other cleaning device that is run through the pipeline prior to the tap.

Once the pipeline has been properly prepared, the hot tap can be made using the selected hot tapping machine. The machine is attached to the pipeline using a special tapping fitting, and a pilot drill is used to create a small hole in the pipeline. The drill is then replaced with a larger cutter, which is used to cut the full-size hole in the pipeline.

Throughout the hot tapping procedure, it is critical to monitor the pipeline's pressure, temperature, and flow rate to ensure that the tap is performed safely and without incident. Once the tap is complete, the new piping or equipment can be installed, and the pipeline can be returned to service.

In summary, the hot tapping method statement is a critical component of the hot tapping process. It outlines the procedures and equipment necessary to safely and efficiently tap into a pipeline while it is still in service. By following a detailed method statement and utilizing specialized hot tapping equipment, operators can minimize downtime and safely install new piping and equipment in their pipelines.
