Increasing interests in marine areas has led to conflicts, and planning of present and future uses is required to achieve sustainable management. Marine Spatial Planning (MSP) is dealt at a national level, but generally it includes ecological, physical processes and administrative jurisdictions of multiple countries. The transboundary cooperation on MSP is a complex challenge, that could be better addressed with a participatory process, to achieve coherent planning processes in shared marine socio-ecological systems. This paper focuses on the process followed to reach consensus on cross-border MSP in archipelagic remote regions with no visible and distant maritime borders. Among the results obtained is the design of a European Macaronesia (Canary Islands, Madeira & Azores) Ocean Pilot Program. This would allow to strengthen marine governance, create synergies between different MSP plans, and comply with EU regulations. A joint position of the European Macaronesia could also be an opportunity for maritime interests in national, European, and international forums. Both the participatory process and the results obtained can serve as a model for application in other transboundary marine areas of the world

对海洋区域日益增长的利益导致了冲突，需要规划当前和未来的用途以实现可持续管理。海洋空间规划 (MSP) 在国家层面处理，但通常包括多个国家的生态、物理过程和行政管辖。MSP 的跨界合作是一项复杂的挑战，可以通过参与式进程更好地解决这一问题，以在共享的海洋社会生态系统中实现连贯的规划进程。本文重点介绍在没有可见和遥远海上边界的群岛偏远地区就跨境 MSP 达成共识所遵循的过程。获得的结果包括欧洲马卡罗尼西亚（加那利群岛、马德拉群岛和亚速尔群岛）海洋试点计划的设计。这将有助于加强海洋治理，在不同的 MSP 计划之间创造协同效应，并遵守欧盟法规。欧洲马卡罗尼西亚的联合立场也可能是在国家、欧洲和国际论坛上获得海洋利益的机会。参与过程和所获得的结果都可以作为适用于世界其他跨界海洋区域的模型
