Ocean energy is a relevant source of clean renewable energy, and as it is still facing challenges related to its above grid-parity costs, tariffs intended to support in a structured and coherent way are of great relevance and potential impact. The logistics and marine operations required for installing and maintaining these systems are major cost drivers of marine renewable energy projects. Planning the logistics of marine energy projects is a highly complex and intertwined process, and to date, limited advances have been made in the development of decision support tools suitable for ocean energy farm design. The present paper describes the methodology of a novel, opensource, logistic and marine operation planning tool, integrated within DTOceanPlus suite of design tools, and responsible for producing logistic solutions comprised of optimal selections of vessels, port terminals, equipment, as well as operation plans, for ocean energy projects. Infrastructure selection logistic functions were developed to select vessels, ports, and equipment for specific projects. A statistical weather window model was developed to estimate operation delays due to weather. A vessel charter rate modeling approach, based on an in-house vessel database and industry experience, is described in detail. The overall operation assumptions and underlying operating principles of the statistical weather window model, maritime infrastructure selection algorithms, and cost modeling strategies are presented. Tests performed for a case study based a theoretical floating wave energy converter produced results in good agreement with reality.

海洋能源项目海洋运营长期规划的决策支持工具

海洋能是清洁可再生能源的相关来源，由于其仍面临与上述电网平价成本相关的挑战，旨在以结构化和连贯方式支持的关税具有重要的相关性和潜在影响。安装和维护这些系统所需的物流和海上作业是海洋可再生能源项目的主要成本驱动因素。海洋能源项目的物流规划是一个高度复杂和相互交织的过程，迄今为止，在开发适合海洋能源农场设计的决策支持工具方面取得的进展有限。本论文描述了一种新颖的、开源的、物流和海上作业规划工具的方法，该工具集成在 DTOceanPlus 设计工具套件中，并负责为海洋能源项目提供包括船舶、港口码头、设备和运营计划的最佳选择的物流解决方案。开发了基础设施选择物流功能，为特定项目选择船舶、港口和设备。开发了一个统计天气窗口模型来估计由于天气导致的运营延误。详细描述了基于内部船舶数据库和行业经验的船舶租赁费率建模方法。介绍了统计天气窗口模型、海事基础设施选择算法和成本建模策略的总体运行假设和基本运行原理。对基于理论浮波能量转换器的案例研究进行的测试产生的结果与实际情况非常吻合。
