14. Holistic Approach to Decommissioning
Consideration of the whole project scope from planning to execution
Highlighting points of interface between disciplines
Identifying activities or operations that may be adversely impacted by each other or be affected by compliance issues.
At the early stages of project planning, involve both engineering and environmental disciplines to ensure methods considered are environmentally sound and would pose minimal concern to stakeholders and regulator.
Minimises risk profile of project
Minimises potential schedule delays
Minimises scope for unforeseen cost increases either through project delays, additional survey requirements or additional monitoring requirements
Reduces risk of project design changes late in the project lifespan
