“…Previous studies have considered 'reefing' as a separate option from other alternatives (e.g. 'deep-water disposal', see Schroeder and Love, 2004); however, we believe this is misleading because all options that retain structure in the marine environment may provide reef habitat, including the option to leave structures in place. The potential for structures to act as reefs should be a decision consideration for all options that retain structure, not just those designated as specific reefing alternatives.…”

“…Thirteen major decommissioning options for oil structures were identified from the literature (Figure 1, Ekins et al, 2006;Lakhal et al, 2009;Macreadie et al, 2011;Osmundsen and Tveterås, 2003;Picken and McIntyre, 1989;Schroeder and Love, 2004). Options range from complete removal and scrapping on shore through to leaving structures in place intact.…”

“…Various stakeholder groups are also likely to have additional considerations that are specific to their interests; for example, coastal property owners are likely to value unobstructed ocean views (Schroeder and Love, 2004). These considerations are often overlooked during decommissioning decisions, yet are likely to be important for ensuring equality and avoiding conflict during the decision process.…”

“…While such predictions appear sound, they require confirmation before the performance of alternative options can be reliably distinguished, even at an ordinal level. Manipulative experiments that examine the impacts of multiple decommissioning options simultaneously are required to determine the extent to which impacts differ among options (Schroeder and Love, 2004).…”

“…For example, RTR options are more likely to optimize social values in the northern Gulf of Mexico, where obsolete structures support an important recreational fishery (Stanley and Wilson, 1990), than in the North Sea where recreational angling on oil structures is minimal (Sayer and Baine, 2002). Numerous decommissioning options are available which fall between the extremes of complete removal and 'leave in place' (Schroeder and Love, 2004). A case-by-case approach to decommissioning is required where the most suitable option is selected from the full range of alternatives, based on the unique decommissioning scenario.…”

Many nations have blanket regulations requiring obsolete structures to be removed, yet this option is unlikely to yield optimal environmental, societal and economic outcomes in all situations. We propose that nations adopt a flexible approach that allows decommissioning options to be selected from the full range of alternatives (including 'rigs-to-reefs' options) on a case-by-case basis. We outline a method of multi-criteria decision analysis (Multi-criteria Approval, MA) for evaluating and comparing alternative decommissioning options across key selection criteria, including environmental, financial, socioeconomic, and health and safety considerations. The MA approach structures the decision problem, forces explicit consideration of trade-offs and directly involves stakeholder groups in the decision process. We identify major decommissioning options and provide a generic list of selection criteria required for inclusion in the MA decision process. To deal with knowledge gaps concerning environmental impacts of decommissioning, we suggest that expert opinion feed into the MA approach until sufficient data become available. We conducted a limited trial of the MA decision approach to demonstrate its application to a complex and controversial decommissioning scenario; Platform Grace in southern California. The approach indicated, for this example, that the option 'leave in place intact' would likely provide best environmental outcomes in the event of future decommissioning. In summary, the MA approach will allow the environmental, social, and economic impacts of decommissioning decisions to be assessed simultaneously in a transparent manner.

The management of offshore platforms at the end of their production phase is a complex issue for technological, socioeconomic, ecological and safety reasons. The decommissioning or reconversion of offshore platforms in the context of a circular economy (CE) will lead to new knowledge acquisition, changing values and changing behaviours towards sustainability consistent with the 'new' business objectives. Multiuse platforms at sea (MUPSs) represent an interesting solution for development of marine infrastructures, including areas in which to start and develop various creative economic activities that are in harmony with the needs of environmental protection including renewable energy, sea shellfish farming, decarbonisation plants, tourism, and recreation. Particularly, the research activity focused on a deep literature review of offshore platform decommissioning and sustainable business model (SBM) in a CE context. This allowed us to access the sustainable business model canvas (SBMC), a conceptual tool that represents a holistic view of the different managerial multiuse options and their social and environmental impacts. Besides, to test the SBMC, we adopt an empirical analysis by semi-structured questionnaires given to a sample of stakeholders in the decommissioning industry. The methodology was enriched by interviews with key informants to better investigate the business ecosystem and the feasibility of decommissioning applied to the case of an Italian offshore platform located in the Adriatic Sea. This article aims to contribute to supporting SBMs development following a holistic approach in relationship with all stakeholders and propose a multi-criteria decision-making analysis for evaluating and comparing alternative decommissioning options.

The decommissioning of offshore platforms has been increasingly discussed due to its economic, social, and environmental impacts. The high complexity of this multilevel context pushes for the adoption of a service ecosystem view to explore the value propositions and actors' relations involved in resource exchanges. This study follows a mixed-method approach based on semistructured interviews conducted with oil and gas stakeholders and content analysis of the secondary data collected.The results highlight the ecosystem elements and identify the main drivers for sustainable growth in the process of the reconversion of oil and gas assets. A "meta" level is theorized to investigate how the actors' purposes can be harmonized with an ecosystem's goal to encourage the diffusion of a sustainable-oriented culture in the context of offshore decommissioning. In this sense, the study provides several insights for researchers and professionals in both the local and national governance field and the oil and gas industry.
