INSITE Synthesis

从石油和天然气转向更多可再生能源的趋势正在加快。已经安装了数千个海洋人造结构（MMS），为社会提供能源的海上碳氢化合物和可再生能源行业提供服务。数以千计的建筑物正在安装，以利用风能。对于那些接近其使用寿命结束的MMS，需要做出紧急决策，以考虑当前的退役做法，并为那些可能需要在未来退役的MMS提供监管建议。全球对退役有不同的要求，尚未就最佳环境结果达成共识。要建立支持可持续活动的管理系统，同时平衡长期的人类和生态需求，就需要就与海洋环境中MMS的部署和退役有关的潜在环境后果达成科学共识，包括积极和消极的后果。这将考虑从个别海洋监测系统到区域海洋的尺度，并包括存在海洋监测系统的生态系统，从大陆架到深海，从极地到热带，目的是通过一个结构化的进程，根据在第一和第二次海洋监测系统下建立的现有证据基础以及其他有关的全球研究，形成对目前科学共识的看法。我们会拟备一份立场文件，就大规模部署、保留或移走不能运作的多媒体管理系统对环境造成的影响，阐述我们的泠苞。为了发展和优先考虑相关的科学问题，我们将确定相关的国际政策承诺，其相关的目的和目标以及MMS与实现这些目标的相关性。重点将放在生态系统后果上，围绕相关科学问题的发展和优先次序达成共识。我们将考虑与不同选择（包括选择的权衡）相关的生态系统变化的社会后果，重点是生态系统服务和社会商品和利益。我们将根据科学共识提出建议，并确定证据基础中存在的关键差距。

There is an accelerating shift away from oil and gas towards more renewable sources of energy. Many thousands of marine man-made structures (MMS) have been installed to service offshore hydrocarbon and renewable energy industries that provide energy for society. Thousands more structures are being installed to harness the power of the wind. For those MMS approaching the end of their operating life, urgent decisions are required to consider current decommissioning practices, and to support regulatory advice for those that may need to be decommissioned in the future. There are different requirements globally for decommissioning and consensus has not been reached on the optimal environmental outcomes. Aspirations for management systems that support sustainable activity while balancing long-term human and ecological needs, requires scientific consensus on the potential environmental consequences, both positive and negative, associated with the deployment and decommissioning of MMS in the marine environment. This will consider scales from individual MMS to regional seas and encompass ecosystems where MMS exist, from the continental shelves to the deep sea, and from the polar regions to the tropics.Through a structured process the aim is to develop a view of the current scientific consensus based on the existing evidence base being established under INSITE I and II and other relevant global studies. We will produce a position paper setting out this consensus view on the environmental implications of deploying MMS at scale, leaving non-operational MMS in situ, or removing non-operational MMS. In order to develop and prioritize relevant science questions, we will identify relevant international policy commitments, their associated objectives and goals and the relevance of MMS to their achievement. The focus will be on ecosystem consequences, with a consensus built around the development, and prioritization, of relevant science questions. We will consider the societal consequences of ecosystem changes associated with different choices (including the trade-offs of choices), focusing on ecosystem services and societal goods and benefits. We will make recommendations based on the scientific consensus, and also determine where critical gaps exist in the evidence base.
