Embodiments of the invention provide a condition-based maintenance tool that may be used to monitor, configure, and in some cases correct, problems experienced by a compressor in a pipeline system. The condition-based maintenance tool may evaluate data retrieved from a compressor status database to identify overconsumption events. In response, the maintenance tool may generate maintenance alarms, initiate work orders, and/or provide recommendations for action to an operator.
