Decommissioning offshore infrastructure

Optimal environmental outcomes for decommissioning of obsolete offshore oil and gas infrastructure

 

A/Prof Peter Macreadie, head of the Blue Carbon Lab, has been appointed as the interim Chair of the Independent Scientific Advisory Board (ISAB) for the newly funded National Decommissioning Research Initiative (NDRI).

With many of Australia’s offshore oil and gas (O&G) structures reaching the end of their lifespan, it has become a research priority to gauge the best way of decommission obsolete rigs while delivering the best environmental outcome.

The NDRI seeks to provide scientifically-robust and independent research on the effects of purpose-built offshore infrastructures on the Australian marine system. To this end, the NERA (National Energy Resources Australia) and industry sponsors Quadrant, Shell, Woodside, ConocoPhillips, Esso, BHP, Vermilion and Chevron will allocate ~ 2.3 M AUD to research projects that tackle three main knowledge gaps:

  1. Investigate the impact that purpose-built structures have on diversity and the extent of life in the marine environment.
  2. Investigate the impact of contaminants on the marine environment, including the influence of material degradation processes over time.
  3. Determine what value is created through retaining infrastructure within the marine ecosystem.

Over the next 3 years, NERA will commission, review, and publish, impartial and credible research on the environmental effects of offshore O&G infrastructures. In the future, this information will enable Australia’s government to take evidence-based decisions when evaluating the future of O&G decommissioning on our coasts.

Australia’s NDRI model is based on the INSITE program (INfluence of man-made Structures In The Ecosystem) developed in the North Sea. Launched in 2012, INSITE has recently concluded their initial phase (2015-2017) with funding from BP, Centrica, CNRI, ExxonMobil, Marathon Oil, Shell, Repsol-Sinopec, Total E&P UK (£2.4M over 3 years).

During this period, INSITE has successfully completed eight research projects (involving 17 European institutions) and will deliver more than 30 scientific publications on the impacts of O&G structures in the North Sea. INSITE recently begun an additional 5-year phase where > £6 M will be allocated to furthering their research plan.
