Abstract
A method for remotely evaluating fatigue damage of a subsea wellhead may include obtaining a plurality of values associated with measurements of a parameter associated with the fatigue damage of the subsea wellhead during field operations, wherein the measurements are measured by a sensor device positioned separately from and adjacent to the subsea wellhead; executing an algorithm using the measurements to generate a result; comparing the result of the algorithm with a range of acceptable values; and determining that the subsea wellhead has a potential failure when the result falls outside the range of acceptable values.
Claims20
A method for remotely evaluating fatigue damage of a subsea wellhead, the method comprising:
- obtaining a plurality of values associated with measurements of a parameter associated with the fatigue damage of the subsea wellhead during field operations, wherein the measurements are measured by a sensor device positioned separately from and adjacent to the subsea wellhead;
- executing an algorithm using the plurality of values to generate a result;
- comparing the result of the algorithm with a range of acceptable values;
- and
- determining that the subsea wellhead has a potential failure when the result falls outside the range of acceptable values.
A system for remotely evaluating fatigue damage of a subsea wellhead, the system comprising:
- a sensor device that is configured to measure a parameter associated with the fatigue damage of the subsea wellhead during field operations, wherein the sensor device is coupled to a host that is positioned separately from and adjacent to the subsea wellhead;
- and
- a controller communicably coupled to the sensor device, wherein the controller is configured to:
- obtain a plurality of values associated with measurements of the parameter, wherein the measurements are measured by the sensor device;
- execute an algorithm using the plurality of values to generate a result;
- compare the result of the algorithm with a range of acceptable values, wherein the range of acceptable values is established using prior results of the algorithm;
- and
- determine that the subsea wellhead has a potential failure when the result falls outside the range of acceptable values.
A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor, enables the computer processor to:
- facilitate obtaining a plurality of values associated with measurements of a parameter associated with fatigue damage of a subsea wellhead during field operations, wherein the measurements are measured by a sensor device positioned separately from and adjacent to the subsea wellhead;
- facilitate executing an algorithm using the plurality of measurements to generate a result;
- facilitate comparing the result of the algorithm with a range of acceptable values;
- and
- facilitate determining that the subsea wellhead has a potential failure when the result falls outside the range of acceptable values.
