Abstract
Systems and methods of detecting key seating wear during drilling operations include a sensor for detecting vibrations in underwater drilling structures and a controller connected to the sensor. The controller processes the data from the sensor to determine if key seating wear is occurring. There may also be a signal injector connected to the controller that is used to inject a signal into the underwater drilling structures. This signal can also be detected by the sensor for use by the controller in determining if key seating wear is present.
Claims21
A system for detecting key seating wear during drilling operations, comprising:
- a sensor configured to detect vibrations in an underwater drilling structure;
- and
- a controller operably connected to the sensor, the controller configured to receive data from the sensor and to process the data to detect key seating wear.
A method for detecting key seating wear in drilling operations, comprising:
- recording vibration data in an underwater structure during drilling operations using a sensor disposed on the underwater structure;
- processing the vibration data from the sensor at a controller operably connected to the sensors to detect key seating wear by filtering the data to detect an anomaly that corresponds to key seating wear.
A key seating detector for offshore drilling, comprising:
- a sensor configured to detect vibrations in an underwater drilling structure;
- and
- a controller disposed on a drill platform and operably connected to the sensor, the controller configured to receive data from the sensor and to process the data to detect key seating wear, and
- an alert device operably connected to the controller, the controller being configured to use the alert device to alert a user to key seating wear.
