Implementation of RCM II (Reliability Centered Maintenance) and RPN (Risk Priority Number) in Risk Assessment and Scheduling Maintenance Task at HPB (High Pressure Boiler) Base On JSA (Job Safety Analysis) (Case study at PT. SMART Tbk. Surabaya)
Abstract: The operational of
High pressure boiler (HPB) in industry has potential to result accident that is
blow up. SMART Corp. Surabaya which is produce palm oil & margarine has
operated HPB to support production process in Refinery & Fractionation
unit. Production capacity of HPB is 1500 kkal with work pressure until 70 bar
and 290 0C temperature. One of the efforts to minimize risk consequences of HPB
operation is by given maintenance. In case, to schedule maintenance task
precisely is required failure and risk assessment to all possibility of
functional failure of equipment. This assessment has not been done by
maintenance division of SMART Corp yet. Hence, This research have study how to
schedule maintenance task at HPB by apply RCM II method and RPN (Risk Priority
Number) in risk assessment. Quantitative assessment is considered to decide
preventive maintenance intervals by examine Maintenance cost (CM) and Repair
cost (CR). JSA will observe potential hazard of maintenance task which have
been scheduled at HPB. From the research result, have been known that there are
25 failure modes which follow functional failure of HPB operation. To
anticipate failure modes of HPB operation, schedule maintenance which have
given by heed RCM II decision diagram are schedule on condition task, scheduled
discard task, scheduled restoration task, and Combination of task. Preventive
maintenance interval determinate at schedule discard & restoration task to
expect that activities are technically feasible to reduce failure consequences
of HPB equipment failure modes. By means of risk assessment with preventive
maintenance interval consideration and also assessment at potential hazard
maintenance task in JSA are expected to help increase effectiveness of
maintenance task has been scheduled
