What are the main phases you must consider in a scheduled decommissioning and closure process?

In a scheduled end-of-life of industrial facility, managing equipment dismantling and demolition requires planning. As seen in chapter 3, some recommended phases should be considered in a scheduled end-of-life project with sufficient lead-in time for completion of the activities:

  • Planning
  • Procurement
  • Project management
  • Implementation:
    • Dismantling
    • Decommissioning
    • Demolition
    • Decontamination
    • Recycling
    • Soil decontamination

All these steps will provide the asset owner with recommendations for the proper and effective management of demolition processes, considering safety and health issues. There are several milestones during the planned decomissioning and closure process that should be considered:

  • 1st stage – Inventory: identify some of the existing objects (structures, engineering networks) that provide life support of neighboring facilities, settlements, etc. This stage also includes an assessment of potential waste volumes and their classification.
  • 2nd stage – Engineering surveys: based on the survey results of the volumes, locations and types of contamination present at the facility, identification of safe disposal streams are identified and documented.
  • 3rd stage – Feasibility study: of the footprint in order to determine the feasibility of development or other use case. The analysis is carried out on the basis of surveys, but also takes into account the legislative issue on the requirements of the future land use possibilities, the location of the facility, its surroundings, transport and traffic networks, competitive environment, the balance of supply and demand for various types of materials in a given location and other factors.
  • 4th stage – Development of projects: for decommissioning, remediation and reclamation Decommissioning projects can be phased with a sequential reduction in the capacity of an industrial facility over several years. Based on the results of the development of projects, the preliminary cost of the work is also determined.
  • 5th stage – Procurement: procedures for the selection of a contractor to perform the demolition work.
  • 6th stage – Execution: of work with bringing the footprint to the required state and meet all final requirements.
