IOGP Report 584
This report is a resource for operators and stakeholders who want to understand the current status of decommissioning requirements around the world.
Different regions of the world have taken varying approaches to understanding and managing the environmental impacts and the regulation of decommissioning and Plug & Abandonment (P&A) activities.
This report is the first of two volumes providing a high level review of the legislation relevant to the decommissioning of offshore facilities and infrastructure (Volume 1) and the Plugging & Abandonment (P&A) of offshore wells (Volume 2 – see IOGP Report 585), for specific hydrocarbon producing countries.
The national legislation of 32 countries was reviewed, as well as relevant international and regional instruments. Countries have been grouped by sea areas, broadly based on the United Nations Environment Programme (UNEP) and associated Regional Seas Programme.
Within each country section, a summary is provided of key regulatory bodies and overarching legislation, focusing in particular on any specific requirements in relation to:
- Decommissioning of platforms and associated infrastructure
- Decommissioning of pipelines
- Actions required with respect to cuttings piles
- Decommissioning plans or similar documents and associated timescales for submission.
