Reliability data analysis and modelling of offshore oil platform plant

摘要

This paper reports on the reliability data analysis and modelling of offshore oil platform plant.We first analysed the effectiveness of preventive maintenance to the plant concerned,and then identified the key sub-units and major preventive maintenance activities to be modelled.A modelling technique called the delay time is then used to determine the optimal periodic inspection intervals.The analysis showed that preventive maintenance is generally effective,but a slight decrease of the periodic inspection intervals is favourable.
