IOGP Report 338
Learn from the experience gained by the industry in the period 1998-2002 in a ‘state-of-art’ review of the technical challenges and other assessment issues considered in order to identify the best disposal option for disused offshore concrete gravity substructures within the OSPAR Maritime Area.
The objective of this document is to present the experience gained by the industry in the period 1998-2002 in a ‘state-of-art’ review of the technical challenges and other assessment issues considered in order to identify the best disposal option for disused offshore concrete gravity substructures within the OSPAR Maritime Area. There are altogether 27 concrete platforms located within the maritime area of the OSPAR Convention, in Norwegian (12), British (12), Dutch (2), and Danish (1) sectors of the North Sea. Between the adoption of Decision OSPAR 98/3 and July 2002, decommissioning of 4 concrete platforms has been considered. Related studies have been carried out and completed and they represent most of the knowledge gained by the industry since 1998. This report updates and replaces that produced in 1996.
