Abstract: Operational integrity management of industrial assets is concerned with systematically and completely reviewing, analysing and developing or sustaining the ability of assets' operations. Breaches of assets' integrity occur when conflicting interests, such as financial, environmental and societal milieus, are incorrectly weighed against each other. In order to attain sustainable asset performance, it is vital to compute the different weights given to the factors governing operational integrity. In this context, it is vital to realise a correct balance between the conflicting interests of employees and the institutionalised interests derived from sustainable asset operations. This manuscript illustrates a study focusing on operational integrity, which has been carried out in collaboration with a leading gas processing and distribution company located in Norway. Also, the manuscript illustrates how to model asset integrity management processes in general and compute operational integrity preference weights complying with 'triple bottom line' using the analytic hierarchy process.

Keywords: operational integrity management; sustainable asset operations; relative preference weights; analytical hierarchy process; AHP; modelling; asset integrity management; Norway.
