NOVEL PRE-DECOMMISSIONING SELECTION TOOLKIT FOR FIXED OFFSHORE PLATFORMS IN MALAYSIA

With the imminent rise of aging offshore jacket platforms in Malaysia,
decommissioning is assuming an integral role here. The decommissioning process
per se is complex and marred with innumerable indeterminate risks associated with
deteriorated structures and the practice of late-life decommissioning planning. The
issue is further compounded by the absence of dedicated decision guidelines and
appropriate local resources. As a way forward, this research proposes a decision aid
toolkit as a management solution for asset owners to plan ahead and optimize the
decommissioning decision making process. Integrating the benefits of Analytic Hierarchy Process (AHP) and an existing asset management system, the toolkit will
provide a quantitative rating model to rank the most feasible decommissioning
alternatives for selected assets. The developed model was tested with an existent
industrial case study for validation and the associated results were in line with
updated industrial best practices. A user-friendly framework presented herein carries
a commercial value which provides for efficient usage of asset information and
professional knowledge in containing decommissioning risk.
