Model of Risk Gas Pipeline Management to Determine Maintenance Strategy
Abstract
Piping system failure often does not occurs in
accordance with the technical life of the pipe. The failure is
caused by the specific content of the gas passing through the
pipeline. The risk management system is designed on the model
of the gas pipeline risk management that can estimate the level of
risk to next five years which is the function of the probability and
consequence of failure. The probability of failure is obtained
based on the corrosion rate of the wall thickness of the pipe while
the impact is determined based on the significance value of 0.3.
Maintenance strategy will be determined based on the results of
inspections conducted on each of three years and failure of
attributes component.
