| The present invention relates to a gas injection control method for a compressor platform, and more particularly, to a gas injection control method for a compressor platform: which determines an operation mode, using a four shutdown valve condition signal transmitted from four sensors detecting the operation condition of shutdown valves installed in a riser pipe between a wellhead manifold line and a gas compressor, and the level two emergency stop signal of a wellhead tower; and which injects the gas generated in the wellhead tower into the wellhead by operating a compressor depending on the determined operation mode or directly injects the gas generated in the wellhead into a wellhead injection line without operating the compressor. Therefore, the gas injection control method for a compressor platform enables to control the operation of gas injection into the wellhead by accurately determining an operation mode depending on the information detected and output by the sensors and the level two emergency stop signal of a wellhead tower, thereby further enhancing reliability of control operation and performing an accurate control. | ||||||

| 155 | WELLHEAD HIPS WITH AUTOMATIC TESTING AND SELF-DIAGNOSTICS | EP12736989 | 2012-01-19 | EP2666096A4 | 2017-08-02 | FLANDERS PATRICK S |
| A method for diagnostics of a high integrity protection system (HIPS) for protection of a pipeline downstream of a wellhead includes: monitoring for initiation of an automatic trip or manual safety shutdown or full shut-off test; determining the process safety time (PST) that elapses between the time at which the upstream pressure reached the trip setpoint and the time at which the upstream pressure reaches the maximum allowable piping pressure (MAPP) of the downstream pipeline; and verifying that the safety critical isolation valves stroked to the fully closed position within ½ PST and that the downstream pressure did not exceed the MAPP. If the verification is successful, no action is required, whereas if the verification shows that either of those parameters are not met, then the HIPS signals an alarm to operators, and in the case of a manual safety shutdown or full shut-off test, resets the pressure trip setpoint to a lower level. | ||||||
