Infrastructure Management for Transport in the Closure stage
- Decommission and deconstruct the transport facilities
- Dispose equipment, materials and inventory
- Interface with the compression and storage decommissioning and remediation teams
- Rehabilitate infrastructure facilities areas and corridors to environment management plan requirements
- Provide any additional infrastructure required to give effect to decommissioning and on going monitoring of the rehabilitated sites / hazardous areas .
- Decommissioning plan and procedures
- Equipment and materials disposal plan
- Environmental rehabilitation and monitoring plan
- Mothballed pipelines / facilities
- Disposed materials/ equipment
- Hazardous waste / contaminated materials disposal report
- Provide input to decommissioning philosophy for the facility
- Identify and assess tasks and options for decommissioning, facility mothballing / disposal including consideration of :
- Environmental impact
- Social impact
- Technical feasibility
- Cost and financial management
- Produce a detaIled decommissioning plan with procedures for the decommisioning of the transport system. This should include
- Identification of the minimum decommissioning requirements.
- Specific guidelines for the decommissioning of topsides, foundations, substructures and subsea components.
- Analysis of the transient effects on shut down
- A detailed review of the requirements of the injection process prior to and during decommissioning and reservior capping, installation of monitoring equipment and the impacts on the transport system.
- Whether pipelines should be removed and if so how this would be carried out, how much would be removed in each lift and what logistics are required, environmental issues of remova land associated costs.
- If pipelines are left on the sea bed what preparations are required to ensure they conform with recommended guidelines and legislation
- How and when subsea structures will be recovered and if any cleaning will take place before or after the disconnection
- Whether structures particularly in off shore disposal solutions should be recovered, merits and implications of non recovery, long term inspection and maintenance of unrecovered structures alternatives to recovery including trenching and burial or surface covering without burial
- Produce an equipment, structures and materials disposal plan including
- Assessment of resale and / or scrap value of equipment e.g. venting facilities, control and monitoring equipment, spare parts piping, etc.
- Material transportation
- Material storage and handling
- Recycling and dumping of materials
- Produce an environmental rehabilitation and monitoring plan including
- Waste management,transportation and handling of contaminated or hazardous materials
- Hazardous waste disposal:
- Spillage and or loss of containment management for cleaning materials
- Collection and disposal particulalry for off shore storage solutions
- offshore structures
- Risk reduction measures
- Assess resources required for decommissioning
- Identify health and safety issues and prepare a detailed health and safety management plan to ensure decommissioning and demolition works will be carried out in a safe, secure and environmental acceptable manner
- Prepare a decommissioning cost report identifying and comparing cost variations for various scenarios of decommissioning, recovery, unrecovery, disposal, rehabilitation
- Implement decommissioing, disposal and rehabilitation plans
