PMS UNDER ISM
IMPLEMENTATION OF A PMS ON BOARD SHIP UNDER ISM:-
1) CORRECTIVE ACTION PROCESSES:- Chapter 9 of ISM code requires the company's SMS to include reporting and analysis of accidents with the objective of improving safety and establishing procedure for implementation of corrective action to prevent recurrence. Corrective action processes such as root cause analysis help identify and eliminate the underlying reasons causing machinery failure, thereby preventing recurrence.
Corrective action process can be shown in following flow chart:-
IDENTIFY THE PROBLEM
ESTABLISH THE CAUSE
PROPOSE SOLUTIONS
EVALUATE SOLUTIONS
ACCEPT ONE REJECT ALL( Go to propose solution)
IMPLEMENT SOLUTION
EVALUATE EFFECTIVENESS
EFFECTIVE INEFFECTIVE( Go to propose solution)
CHAPTER CLOSED
Element 10.2.3 of ISM code requires the company to carry out appropriate corrective action to ensure that the ship is maintained in conformity with rules and regulations.
2) DEVELOPING AND IMPROVING MAINTENANCE PROCEDURE:-
i) Element 10.3 of the ISM code requires companies to identify critical system, the failure of which may be hazardous and provide measures aimed at promoting reliability. So, company should develop the maintenance plan in such way that critical item or system should not fail and their standby operation is always ready.
ii) The maintenance recommendation and specification of the equipment manufacturer.
iii) The history of equipment including failure, defects and damage and the corresponding remedial action.
iv) Input obtained from third party inspection i.e. class, administration must be incorporated into the maintenance system.
v) The age of ship should be considered.
vi) Use of trend analysis and condition monitoring to ensure timely remedial action.
3) SYSTEMATIC APPROACH TO MAINTENANCE:- A systematic approach to maintenance will include
i) The establishment of maintenance interval
ii) The definition of method and frequency of inspection
iii) The specification of type of inspection and measuring equipment to be used and the accuracy required of it.
iv) Establish specific acceptance criteria (Go/No go)
v) The assignment of responsibility for inspection and maintenance activities to appropriately qualified person.
vi) The clear definition of reporting mechanism and requirement
vii) Maintaining a good inventory management system
4) MAINTENANCE INTERVAL:- It should be based on following
i) The manufacturer recommendation and specification
ii) Predictive maintenance determination technique ( L.O. analysis, vibration analysis etc)
iii) Practical experience in the operation and maintenance of the ship and its machinery including historical trends in the results of routine inspection and in the nature and rates of failure.
iv) The use to which equipment is put continuous, intermittent standby or emergency
v) Practical or operational restrictions e.g. maintenance which can only be done in the dry dock
vi) Intervals specified as part of class, administration, convention and company requirement
vii) The need for regular testing of standby arrangements.
viii) A trend to be developed by condition monitoring to maximize maintenance interval
5) INSPECTION:- Element 10.2.1 of ISM code requires inspection to be carried out at appropriate intervals to ensure conformance to regulations. Procedure for planned inspection routine should be written to include the following
i) Inspection to be integrated into ship's operational maintenance routine( 10.4)
ii) Procedure for specific inspection routines to be documented and their acceptance criteria establish.( Pass/ fail, tolerance)
iii) The use of suitable measuring and testing equipment of the required accuracy
iv) The calibration of measuring and testing equipment to appropriate standard
v) Format of inspection report and corrective action process to be well defined
Following are example of type of inspection and test
a) Visual b) Vibration c) Pressure d) Temperature
e) Electrical f) Load etc.
