The overall objective of this course is to provide delegates with an introduction to, and awareness of, the activities involved in the whole life-cycle of a decommissioning project. You will learn the associated key issues from initial planning through execution.   The principles introduced are transferable across most assets and facilities and provide an insight from an Operator’s perspective, hence providing the most comprehensive introduction to all aspects of the decommissioning process.
