One of the major challenges faced in-field whilst executing the disconnection and demobilisation (D&D) scope is often the removal of NORM decontamination from the FPSO’s process and cargo systems.
The scope and extent of the NORM decontamination carried out was vast.
NORM can surface naturally or through human activities such as mining, and oil and gas extraction. NORM is radioactive. Once it is brought to the surface or concentrated, the ionizing radiation that it emits can affect humans resulting in various cancers.
Ensuring that the decontamination scope was detailed and sufficient for decontamination contractors to be effective on the project was essential to protecting people during the decommissioning process.
