20090101338 | Wellhead flowline protection and testing system with ESP speed controller and emergency isolation valve - An ESP variable speed drive controller functions in conjunction with a safety logic solver, dedicated pressure sensors and a surface emergency isolation valve, or safety shut-off valve (SSV), to perform a full functional test of the complete wellhead flowline system. The method includes the step of using a plurality of pressure transmitters to monitor the flowline pressure during normal operations and during a full stroke test of the safety shutoff valve and adjusting the speed of the downhole ESP during the test to maintain the pipeline pressure within predetermined safe pressure limits. This wellhead flowline protection system and method utilizes the downhole ESP speed controller and an SSV to ensure that dangerous pressure levels are not reached and provides for full functional safety testing of the wellhead system. The ESP motor speed controller is used to permit functional testing and remove the pressure source from protected downstream flowline piping. | 04-23-2009 |
20090121868 | Local emergency isolation valve controller with diagnostic testing and trouble indicator - A local logic solver that operates with a local smart valve controller to control, test and monitor performance characteristics of a local field-mounted emergency isolation valve device, outputting a local indication of trouble on the device, which is mounted in the field away from the facility's central control panel for the process. The local logic solver includes a recording function and memory for retrieval of detected faults that are time-stamped and recorded locally to generate documentation and to track the elapsed time, starting when the degraded state of the device was detected and first signaled as a problem; other performance data is also recorded. Accordingly, the operation of the overall system is simplified by eliminating the need for an external computer to diagnose any problems. A local control panel preferably includes pushbuttons and lights used during routine operations of the valve and a fault indicator light substantially adjacent to or in close proximity to the device being monitored to alert personnel of detected faults. | 05-14-2009 |
