Research Program 2 Project 3: Risk-based Marine Impact Assessment of Naturally Occurring Radioactive Materials (NORMs) and Mercury from Decommissioning Oil and Gas Infrastructure

Full Project Title

Risk-based Marine Impact Assessment of Naturally Occurring Radioactive Materials (NORMs) and Mercury from Decommissioning Oil and Gas Infrastructure

NDRI Reference

Project 2.3

Project Proponents

Curtin University Oil and Gas Innovation Centre (CUOGIC) with the University of Aberdeen

Delivery

Q2 2022

Objectives

The project’s aim is to enhance understanding of the risks of NORMs and Mercury to marine environment from oil and gas infrastructure under various decommissioning scenarios.

Background

While naturally occurring, oil and gas production can concentrate Naturally Occurring Radioactive Materials and Mercury between wellhead and along a pipeline route. This project seeks to understand how different decommissioning options might affect the release of NORMs and Mercury and the potential risk of effects on marine life.

 

Objectives
  • Undertake a desktop study to consolidate the state of knowledge on protective standards and impact of NORMs and Mercury exposure on the marine environment at various concentrations.
  • Determine applicable standards and guidelines for identification and measurement of NORM and mercury types and quantities.
  • Understanding of NORM and mercury location, concentration, speciation, mobility and risk in marine receptors, considering various decommissioning scenarios.
  • Risk-based marine environmental impact assessment of NORM and mercury from oil and gas infrastructure under various decommissioning scenarios.
