Abstract

Since 1973 concrete gravity structures have been used to extract oil and gas within the OSPAR Maritime Area. As oil and gas supplies are depleting these structures will require decommissioning over the next 10 to 20 years. During design and construction, removal was rarely considered and it is anticipated that this can be extremely high in cost and safety risk. Leaving the structure in situ is a consideration of which there are concerns about the service life of the concrete. Little is known about the durability and failure mechanisms of such structures. Previous research to determine the most probable service life and failure mechanisms is limited as the majority has focused on atmospheric and splash zones, considered to be worst case.
