  1. ADRIATIC MARITIME LAW CONFERENCEPORTOROŽ, 26-28 May 2016Marine Environmental Impactin the Process of Decommissioning of Offshore Structuresin the European Perspective Jana Rodica LL.M.

  2. Introductory outline • First attempt Cobb seamount in 1970 • Definition and Legal Status of Offshore Structure • There are more than 1000 offshore oil andgas installations operating just in Europeanwaters • The offshore energy industry has averaged 130 platform removals per year

  3. Marine Environmental Impact in the Process of Decommissioning of Offshore Structures

  4. Total or partial removal Sinking/toppling on site Leave in place Potential Ecological Consequences of Offshore Platform Decommissioning in the Gulf of Trieste

  5. Leave in place • The world has already lost 27% of its coral reefs from human activities. Leave the disused offshore structure in place can be helpful in making up for what has been lost • Several Rig-to-reef programs in place

  6. Underwater Acoustic Pollution in the process of Decomissioning of offshore structures • IMO • The European Union • ACCOBAMS

  7. Regulatory framework for the decomissioning of Offshore structures • The Imo guidelines - Removal Guidelines • The 1972 London Convention and its 1996 Protocol • The 1958 Geneva Convention on the Continental shelf • The 1972 Oslo Convention • The Ospar Convention • United Nations Convention on the Law of the Sea • The EU approach

  8. Marine Pollution • Marine Pollution – Principles of Customary International Law • Main Forms of Responsibility for Environmental Harm in International Law • - Strict liability; - Liability based on fault. • Liability – “Slovenian Perspective”

  9. Insurance related issues • Decomissioning is a multy-phased techical process more akin to construction that operation • Risk exposure to residual liabilities (including abandonment), pollution or contamination in the process of dismantling/removal • Damage to exiting property not intended for decommissioning next to the structures to be removed

  10. Old problems, innovativesolutions The group All Seas as well as groupHeerema, are currently building “huge“ decommissioning vessels. Heerema is building a new crane vessel with two 10.000 tons cranes. By far the biggest lifting capacity in the world. ex. Pieter Schelte, the world’s largest platform installation / decommissioning and pipe laying vessel https://youtu.be/UviT9ox-gok Comments and Conclusion
