Decommissioning decision makers often need to determine the best and most practicable options for pipelines, flowlines, and power cables, including leave-in-place strategies or removal. This study presents results from several evaluations using advanced methods to support the determination of options.

This paper discusses various best practice technical strategies for decommissioning which can be applied in the Southeast Asia region, and throughout the world. The strategies proposed can result in an estimated operator saving of more than 30% over the entire decommissioning execution expenditure. The processes discussed are included in the typical steps of prelimina…
