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.

可持续商业模式的有用性：来自石油和天然气行业的分析

由于技术、社会经济、生态和安全原因，海上平台在生产阶段结束时的管理是一个复杂的问题。在循环经济 (CE) 背景下，海上平台的退役或重新改造将导致新知识的获取、价值观的改变和行为的改变，以实现与“新”业务目标一致的可持续性。海上多用途平台 (MUPS) 代表了海洋基础设施发展的有趣解决方案，包括在这些领域启动和发展符合环境保护需求的各种创造性经济活动，包括可再生能源、海贝养殖、脱碳工厂、旅游, 休闲. 特别，研究活动的重点是对 CE 背景下海上平台退役和可持续商业模式 (SBM) 的深入文献综述。这使我们能够访问可持续商业模式画布 (SBMC)，这是一种概念工具，代表了不同管理多用途选项及其社会和环境影响的整体视图。此外，为了测试 SBMC，我们通过对退役行业利益相关者样本进行的半结构化问卷进行实证分析。该方法通过与关键知情人的访谈得到丰富，以更好地调查商业生态系统和退役的可行性，适用于位于亚得里亚海的意大利海上平台的案例。
