(OTC 24211) Fundamental and Specific Marine Geohazard Risk Assessment Categorisation

摘要

Until around 1990 the main marine geohazard risk addressed solely from geophysical data was the presence of shallow gas. Presence had been described using a number of non-standard approaches for its potential presence - distinct from the actual risk it presented to operations. In the 1992 UKOOA Guidelines for the delivery of marine rig site surveys a standardised nomenclature was suggested that was largely taken up as a standard by the industry.
