EMB Policy Brief No. 3 - Decommissioning of offshore man-made installations: Taking an ecosystem approach

Idioma

Inglés

This Policy Brief assesses the role of marine science in reducing the environmental impact of decommissioning and highlights the scientific questions that now need to be answered to settle the debate on what should be done with these structures. The total cost of full decommissioning of oil and gas installations in the North Sea alone for the period 2015 to 2040 is estimated at between US$70 and US$82 billion. The numbers of installations requiring decommissioning is also set to increase dramatically as renewable energy devices begin reaching the end of their operational life, and as plans for exploiting renewable energy sources in the near future grow. Globally, industry and governments are embracing different decommissioning approaches, from full removal to the production of artificial reefs. The question of what is best for the environment is still to be answered.

The INSITE programme, highlighted in this Policy Brief as novel model which could be implemented more widely, is a unique collaboration between leading energy companies and research. It is already funding research which is exploring the influence of man-made structures on the marine ecosystem in order to provide a solid scientific basis for future decision-making.

Ultimately, appropriate decisions need to be made in the very near future regarding the decommissioning of oil and gas and renewable energy structures. At present, there remains a need for more scientific research to better inform the decision-making process regarding their fate.
