Once topsides and substructures are transported to shore they are managed under the waste hierarchy, considering re-use, recycling or disposal. Owners of oil and gas infrastructure have a duty of care which enforces the responsible handling of infrastructure from construction to final disposal. Due to the nature of oil and gas production, some of the materials and fluids in a facility being decommissioned may be contaminated. Normally Occurring Radioactive Material (NORM) and Low Specific Activity (LSA) scale are amongst the contaminants commonly encountered during decommissioning. Therefore licences, controls, mitigations, handling and disposal methods have been established to manage and dispose of such wastes. Once the infrastructure is onshore, the disassembling and processing takes place on specialist licensed sites in accordance with an approved waste management system.
