This guideline is supplementary to the “Guidelines on Decommissioning Cost Estimation” released in September 2013.
This document aims to provide a high-level overview of the elements that make up the scope of a decommissioning project, and the activities within each element for which costs should be allowed. Although the list of items shown within the WBS is comprehensive, every decommissioning project is unique and there may be other activities required. This WBS is intended to act as a guide only. It is not intended to be a detailed project management tool and operators retain the freedom to deviate from the WBS to ensure fitness for purpose for any given project, or to fit business needs.
