“…Over 127 platforms, 50% of the total population of fixed platforms on the UKCS, exceeded the original design life in 2003 (Stacey et al, 2008). It is necessary to consider the issue of LE beyond the design life in the thorough review process and make provision for assessment of ageing (HSE, 2005).…”

“…3.1 Drivers a) End of Life: oil and gas production in the UK Continental Shelf (UKCS) started in the 1970s [4]. Considering that a significant number of the facilities have a design life of 25 years [15], then facilities installed prior to the 1990s are likely due for decommissioning. Life extension programmes are currently employed to keep facilities in operation beyond their design lives [16].…”

Offshore decommissioning represents significant business opportunities for oil and gas service companies. However, for owners of offshore assets and regulators, it is a liability because of the associated costs. One way of mitigating decommissioning costs is through the sales and reuse of decommissioned items. To achieve this effectively, reliability assessment of decommissioned items is required. Such an assessment relies on data collected on the various items over the lifecycle of an engineering asset. Considering that offshore platforms have a design life of about 25 years and data management techniques and tools are constantly evolving, data captured about items to be decommissioned will be in varying forms. In addition, considering the many stakeholders involved with a facility over its lifecycle, information representation of the items will have variations. These challenges make data integration difficult. As a result, this research developed a data integration framework that makes use of Semantic Web technologies and ISO 15926-a standard for process plant data integration-for rapid assessment of decommissioned items. The proposed solution helps in determining the reuse potential of decommissioned items, which can save on cost and benefit the environment.

“…The majority of the North Sea platforms have, for instance, reached the end of their designed service life and as such are currently operating out-with their life expectancy (The UK Oil and Gas Industry Association, 2017). The structural performance of platforms has been affected by the aggressive marine environment through material deterioration (e.g., steel corrosion) leading to the reduction of platform durability (Stacey et al, 2008). Many platforms have additionally undergone significant structural changes, such as topside extensions to accommodate new, more efficient oil extraction equipment or additional living quarters.…”
