About the course

This course provides learners with an awareness of the approaches, issues and challenges associated with developing decommissioning programmes for North Sea oil and gas fields.

It details the complete decommissioning process from beginning to end covering: planning activities and considerations; well plugging and abandonment; approaches to the decommissioning of structures and pipelines and the associated onshore activities. In addition, given the current climate and the need to reduce the taxpayer contribution to decommissioning, innovation leading to cost saving approaches to decommissioning will be considered and discussed.

This course is suitable for anyone working or interested in the decommissioning sector, and will provide learners with the knowledge of the various stages of a decommissioning project and what is involved, including the applicable regulations and legislation.
