Methods and systems for monitoring operation of equipment

A method of maintaining a baseline parametric curve representing normal operation of a first unit, wherein the first unit is one of a plurality of substantially similar units included in an equipment fleet, said method comprising:

• receiving a selection of at least one source of data related to the operation of the first unit;
• receiving data from the at least one selected source of data;
• sampling data associated with at least one data parameter from the received data;
• and
• determining the baseline parametric curve by fitting a curve to the data associated with the at least one sampled data parameter.

A condition assessment device for monitoring the operation of at least one of a plurality of units included within a fleet of substantially similar units, said device comprising a processing device configured to store at least one code segment configured to instruct said processing device to:

• receive a selection, from an input device, of at least one source of data related to the operation of at least one of the plurality of units;
• receive data from at least one sensor associated with the at least one source of data;
• sample data associated with at least one data parameter from the received data;
• and
• generate a baseline parametric curve from the data associated with the at least one sampled data parameter.
