Predictive / Condition Maintenance Beneffits

Predictive maintenance strategy will allow your crew to prioritize maintenance tasks to improve the reliability of your equipment, in an organized manner and based on real measurements while the machinery is in service. Predictive maintenance in return will provide following:

1.  Reduced Maintenance costs up to 50%. 

1. The early detection of a developing fault weeks before catastrophic failure occurs, will allow more time to order the necessary spares and forward to the ship at a convenient port. Will also allow  valuable time to the company's procurement department to asses and select appropriate quality spares, negotiate prices , delivery time and finally to find the most cost effective way to send the parts to more convenient ports.
2. The identification of developing fault(s) will greatly assist to order the spare parts really required and not to second guess what exactly is required, thus can lead to a significant reduction of parts retained on board and reduce respective cost of stocking.
3. Intervention for required maintenance will be possible to be scheduled well in advance thus less Man-Hrs will be required, specially if the correct parts are availiable.
4. No over maintenance thus no unnecessary expenditure on spare parts and Man-Hrs
5. Minimizing Catastrophic failures due to wear and tear or bad maintenance procedures will preventing major unexpected expenses.  

2.  Increased reliability up to 100%. 

 Increased Equipment reliability up to 97%. Studies to Shore Industries have indicated that the reliability has increased up to 97-100% and the unexpected downtime of the equipment has decreased to less than 3%. The financial savings from the increased reliability are estimated to be more than US$100,000/year/vessel

3. Accurate creation of Dry Dock specification.

It is common problem among ship management companies to compile an accurate Dry-Dock specification, specially for machinery items or complex systems. Most of the times budget, estimated operational condition and time constraints make the final decision difficult and most of the times the decision is based not on concreate data but on attending engineers intuition.

4. Evaluation of Maintenance Interventions

It is assumed that maintenance interventions will restore the equipment’s operating condition to its nearly “as new” status, however many times the maintenance intervention is not successful and in some occasions the health rating is less than before the intervention due to incomplete or unprofessional practices.

5. Vetting companies increased rating

Vetting companies like “Rightship” they strongly recommend the adoption of condition based maintenance system in conjunction with the existing preventive maintenance system, same as tanker ships vetting companies requiring CAS.

6. Classification Societies recently adopted CbM practices.

Many times the engineers or the crew on board they are faced with the difficult task to open a piece of equipment which is in an apparent good health because the class surveyor requires to see the machinery in open condition or does not accept Ch. Engineers report, now it is possible to avoid open up inspections based on CbM measurements.
