GARAH WP2: Report describing a catalogue of hazards, alternative uses and case studies: Deliverable 2.6

In this report of the GARAH project we present a catalogue of potential alternative usages, synergies and competitions of a mature offshore area and associated infrastructure after closure. Recent case studies exemplify the different technological developments and address further research needs. Additionally, a catalogue of potential environmental hazards and risks accompanying the use of the subsurface has been compiled. The report is a joint task between WP2 and WP3 of the GARAH project and reports on the work related to Task 2E: Multiple/alternative use of HC reservoirs.
