To support the framework, data collection gathered
from field thorugh observation, record study &
interview with operator.Scope of observation is limited
to compressor cooling water system which intercooler
is part of the system. Observation start from
performing PM Analysis of cooling water system. PM
stands for “Phenomena are phyisically analyzed then
mechanism of phenomena & equipment analyzed &
understood; relationship between Machine, Material,
Man & Method are pursued”.
[Shirose,Kunio,1999:36]. This method used to identify
abnormality found on each process. To begin with,
draw process flow of compressor cooling water system
