Obtaining insight into the common predictors of machinery failure can be an expensive endeavour. What is usually missing is the ability to make a conclusion from all the data available on board. Also managing properly the dataflows that machine failures trigger can be challenging.

By definition: 

"Condition Based Monitoring is a maintenance strategy that allows monitoring the actual condition of an asset, extracting information to understand the machines' actual wear, degradation and if a relevant change has occurred."

Condition-based monitoring is an approach to integrate machine data with existing PMS (MPMS notation). Users gain the benefit of insightful data that can integrate with their existing PMS/ERP and IMS processes to execute anything related to predictive or proactive machinery maintenance i.e. maintaining the machinery Just In Time (JIT).
Most time-based maintenance periods are arbitrary, based on initial Maker’s recommendations which in most cases go unquestioned and remain set throughout the vessel’s life.

It is impossible for Maker to undertake a full analytical maintenance justification for every piece of equipment.
 Most marine vessel failures occur due to unnecessary and excessive maintenance , incorrect installation, poor design and incorrect operation.
Condition monitoring, when combined with maintenance processes have demonstrated significant benefits throughout the maritime industry in terms of reducing maintenance activities and costs, helping to avoid unplanned stoppages and more.
 
Condition-based maintenance processes, properly applied, can help to identify and rectify problems at an early stage and can improve marine machinery reliability and reduce maintenance costs significantly.
 
This has been confirmed by the major classification agencies ( DNV GL, LR, ABS). Keeping machinery running in optimum condition reduces the likelihood that it will fail in service, leading to improved reliability and increased efficiencies.
