Abstract

A method for operating a drilling plant machine includes providing a drilling plant machine which includes a sensor which measures a parameter which is indicative of a jarring load acting on the drilling plant machine from a drill string, providing a set of values representing readings from the sensor, identifying a jarring event, and determining a magnitude of the parameter from the set of values.

First claim

What is claimed is:

1 - 25 . (canceled)

26 . A method for operating a drilling plant machine, the method comprising:
providing a drilling plant machine comprising a sensor which is configured to measure at least one parameter which is indicative of a jarring load acting on the drilling plant machine from a drill string; providing a set of values representing readings from the sensor; identifying a jarring event; and determining a magnitude of the at least one parameter from the set of values.

27 . The method as recited in claim 26 , wherein the sensor is a force sensor, a vibration sensor, a displacement sensor, of an acceleration sensor.

28 . The method as recited in claim 26 , wherein the at least one parameter is or is a function of at least one of:
a force acting on the drilling plant machine, a displacement of the drilling plant machine, a displacement of a component of the drilling plant machine, an acceleration of the drilling plant machine, a vibration amplitude of the drilling plant machine, and a vibration frequency of the drilling plant machine.

29 . The method as recited in claim 26 , further comprising:
determining a time (t 1 ) at which the jarring event occurred.

30 . The method as recited in claim 29 , wherein the determining of the magnitude of the at least one parameter from the set of values includes:
determining a time period (t J ) encompassing the time (t 1 ) at which the jarring event occurred, and determining at least one of:
a peak value of the at least one parameter in the time period,
an average value of the at least one parameter in the time period, and
a median value of the at least one parameter in the time period.

31 . The method as recited in claim 26 , wherein the identifying of the jarring event comprises at least one of:
receiving a signal generated by an operator indicating that a jarring event has been executed, and comparing the magnitude of the at least one parameter to a first pre-determined threshold value, the first pre-determined threshold value being indicative that a jarring event has taken place.

32 . The method as recited in claim 31 , further comprising:
outputting a first signal which is indicative of the magnitude of the at least one parameter.

33 . The method as recited in claim 32 , further comprising:
providing a maintenance scheduling system which is configured to,
receive the magnitude of the at least one parameter, and
output a second signal if the magnitude of the parameter exceeds a second pre-determined threshold value, the second signal being indicative of a need to perform maintenance on the drilling plant machine.

34 . The method as recited in claim 33 , wherein,
the drilling plant machine further comprises a first component and a second component, and the maintenance scheduling system is further configured to output a third signal if the magnitude of the at least one parameter exceeds a third pre-determined threshold value, the third signal being indicative of a need to perform maintenance on the first component.

35 . The method as recited in claim 34 , wherein the maintenance scheduling system is further configured to output a fourth signal if the magnitude of the at least one parameter exceeds a fourth pre-determined threshold value, the fourth signal being indicative of a need to perform maintenance on the second component.

36 . The method as recited in claim 26 , further comprising:
providing a maintenance scheduling system, the maintenance scheduling system being configured to:
output a first value which is indicative of a remaining useful lifetime of the drilling plant machine,
receive the magnitude of the at least one parameter,
calculate a second value which is a function of the first value and the magnitude of the at least one parameter, the second value being indicative of an updated remaining useful lifetime of the drilling plant machine, and
output the second value.

37 . The method as recited in claim 26 , wherein the drilling plant machine is,
a drilling machine, a top drive, a hoisting machine, a heave compensator, or a power tong machine.

38 . A tangible computer readable medium comprising instructions stored thereon which, when executed by a processor, causes the processor to perform the steps of the method as recited in claim 26 .

39 . A drilling system comprising:
a drilling plant machine; a sensor configured to measure at least one parameter which is indicative of a jarring load acting on the drilling plant machine from a drill string; and a processor configured to receive a set of values measured by the sensor and to determine a magnitude of the at least one parameter from the set of values.

40 . The drilling system as recited in claim 39 , wherein the sensor is a force sensor, a vibration sensor, a displacement sensor, or an acceleration sensor.

41 . The drilling system as recited in claim 40 , wherein the at least one parameter is or is a function of at least one of:
a force acting on the drilling plant machine, a displacement of the drilling plant machine, a displacement of a component of the drilling plant machine, van acceleration of the drilling plant machine, a vibration amplitude of the drilling plant machine, and a vibration frequency of the drilling plant machine.

42 . The drilling system as recited in claim 39 , wherein the processor is further configured to determine a time (t 1 ) at which the jarring event occurred.

43 . The drilling system as recited in claim 42 , wherein the processor is further configured to,
determine a time period (t J ) encompassing the time (t 1 ) at which the jarring event occurred, and determine at least one of:
a peak value of the at least one parameter in the time period,
an average value of the at least one parameter in the time period, and
a median value of the at least one parameter in the time period.

44 . The drilling system as recited in claim 39 , wherein the processor is configured to identify the jarring event if at least one of,
a signal generated by an operator indicates that a jarring event has been executed, and the magnitude of the at least one parameter exceeds a first pre-determined threshold value, the first pre-determined threshold signal being indicative of the jarring event having taken place.

45 . The drilling system as recited in claim 44 , wherein the processor is further configured to output a first signal which is indicative of the magnitude of the at least one parameter.

46 . The drilling system as recited in claim 45 , further comprising:
a maintenance scheduling system which is configured to:
receive the magnitude of the at least one parameter, and
output a second signal if the magnitude of the at least one parameter exceeds a second pre-determined threshold value, the second signal being indicative of a need to perform maintenance on the drilling plant machine.

47 . The drilling system as recited in claim 46 , wherein,
the drilling plant machine further comprises a first component and a second component, and the maintenance scheduling system is further configured to output a third signal if the magnitude of the at least one parameter exceeds a third pre-determined threshold value, the third signal being indicative of a need to perform maintenance on the first component.
