1. An apparatus for predicting equipment damage, the apparatus comprising:
an input;
a processor; and
an output;
wherein the input is configured to provide the processor with sensor data for an item of equipment,
wherein the processor is configured to implement at least one machine learning algorithm,
wherein the at least one machine learning algorithm has been trained based on a plurality of calibration sensor data for the item of equipment,
wherein training of the at least one machine learning algorithm comprises:
processing the plurality of calibration sensor data to determine a plurality of associated key condition indicator data,
transforming the key condition indicator data using a moving average calculation over time to obtain transformed key condition indicator data, and
determining at least two clusters representative of different equipment states by determining at least two distributions of the transformed key condition indicator data,
wherein the processor is configured to implement the at least one machine learning algorithm to process the sensor data to assign the sensor data to a cluster of the at least two clusters to determine an equipment state for the item of equipment, and
wherein the output is configured to output the equipment state for the item of equipment.
