蓝色增长是在海上创造经济活动和就业机会，而空间的多重利用通过合并工业来有效利用可用海域。显然，有许多组合和许多价值主张。然而，到目前为止，大多数技术都被认为是蓝天概念，很少有强有力的技术经济分析表明有利可图。本文首先全面回顾了蓝色增长和在蓝色增长中的多用途；从政策和广泛的当前技术，包括海洋能源、海上风能、海上水产养殖和海水淡化。Maribe H2020项目为论文的研究内容提供了载体。其主要贡献是为多用途空间(MU)和多用途平台(MUP)选择、筛选、开发和排序业务主张的新方法。该方法的应用首次确定了三个案例研究，在这些案例中，Blue Growth组合项目在经济上是可行的，具有诱人的内部回报率(IRR)。为案例研究提供的结果报告了标准投资指标，并显示了每种产品(能源、食品、水)对系统盈利能力以及社会经济影响的相对贡献。现有的公司充分参与了这一进程。行业专家和行业之间的共同创造既改善了商业价值主张，也带来了对投资准备情况的强有力评估。与认为大型平台具有商业吸引力的假设相反，排名最高的案例研究公司需要较少的资本支出(CAPEX)，并在利基细分市场运营。总而言之，案例研究的积极经济表现应该会让欧共体和投资者相信MU和MUP拥有可行的经济前景，从而走向商业化。宏观和微观评估方法将在其他蓝色经济背景和其他多种产品背景下特别有用。
Blue Growth is the creation of economic activity and jobs at sea, while multiple use of space makes efficient use of the available sea area by combining industries. Clearly there are many combinations and many value propositions. However, most technologies to date are considered blue sky concepts, with little robust techno-economic analysis demonstrating profitability.The paper begins by providing a comprehensive review of Blue Growth and multi-use in Blue Growth; both in policy as well as the wide range of current technologies, including ocean energy, offshore wind energy, offshore aquaculture and desalination.The Maribe H2020 project provides the vehicle for the research element of the paper. The major contribution is a new methodology for selecting, filtering, developing and ranking business propositions for multiple-use of space (MUS) and multi-use platforms (MUP). Application of the method for the first time identified three case studies where Blue Growth combination projects can be economically viable, with attractive internal rate of return (IRRs). Results presented for the case studies report standard investment metrics and show the relative contribution of each product (energy, food, water) to the system profitability, as well as socio-economic impact. Existing companies were fully engaged in the process. Co-creation between sector experts and industry led to both improved business value propositions and robust assessment of investment readiness. In contrast to the presumption that large scale platforms are commercially attractive, the highest ranking case study companies required smaller capital expenditure (CAPEX) and operated in niche subsectors.In conclusion, the positive economic performance of the case studies should provide confidence for the EC as well as investors that MUS and MUP have viable economic futures leading towards commercialisation. The macro and micro assessment methods will be particularly useful in other Blue Economy contexts and in other multiple product contexts.
