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.

Development of the marine renewable energy (MRE) industry has been challenged by uncertainty about potential environmental effects, which has resulted in slowing of permitting/consenting processes, and ultimately to constraints on the industry. These challenges result from a lack of sufficient devices in the water from which to learn, a dearth of quality monitoring data, and a lack of accessibility to information about these effects in general. This paper describes an ongoing process to improve understanding of the environmental effects of MRE through a public, online knowledge management system developed by the U.S. Department of Energy, known as Tethys (https://tethys.pnnl.gov). Tethys collects and curates relevant documents while supporting a diverse international community through intentional outreach and synthesis activities, many of which support an international collaboration under the IEA Ocean Energy System’s Annex IV. After eight years of operation, Tethys is internationally recognized and viewed as a trusted broker of information, with over 50,000 visitors annually. Tethys has provided clarity around environmental effects during a critical time in the industry when deployments are increasing in size and frequency.

Development And Utilization

AbstractThe Chinese government has attached great significance to the research, development, and utilization of marine renewable energy (MRE), all of which made significant achievements in the year 2012. This paper systematically reviews and analyzes the development status of China's MRE industry, in terms of resources, policies, and technologies. Some problems are also pointed out, in order to provide further suggestions for China's MRE sector in the future. Prospects and main tasks in the near future are proposed to establish the demonstration bases of MRE and the national public supporting platform for MRE. The development and utilization of MRE have become a significant measure for China for increasing renewable energy power, optimizing energy structure, developing the marine economy, and reducing power shortages on islands. In the future, China will continue to promote the R&D of ocean energy technology as well as the development of technology demonstration and perfection among service providers of industrial applications.
