Hotelling T2 Technique applied in a marine propulsion engine

Normally, when the process variables are monitored individually, it can be complex to identify when the process has a deviation from his normal working conditions. This paper presented a methodology based on MSPC (Multivariate Statistical Process Control) that provides plant managers, timely and appropriate information to the correct decision making before possible deviations in the process. The cylinder lubrication process of a 2T marine diesel engine was monitored using Hotelling T2 multivariate control charts. The control charts detected deviations in the process with respect to normal operating conditions, before which appears an alarm marked by the manufacturer of the engine. This helped the ship ́s engineers to prevent a possible malfunction or shut down of the engine and avoid an operational cost increased.
