This book was released on 2016 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the offshore wind energy sector expands due to government mandates, a thorough understanding of the geologic setting of potential project sites becomes an essential component in the design process. Geophysical and geotechnical parameters yield vital information on the sediments and/or rocks that are present. The variable distribution of sediments, with concomitant variations in geotechnical properties, has significant implications for the selection (e.g., monopile, suction caisson, gravity base, jacket), design, location, installation, and subsequent scouring in the vicinity of wind turbine foundations. Identifying suitable sites based on sediment types allow for optimized engineering design solutions. Because foundations represent approximately 25% of total offshore wind project expenditures, reducing foundation costs with geologic suitability in mind could significantly decrease required initial investments, thereby expediting project and industry advancement. To illustrate how geological and geotechnical data can be used to inform site selection for foundations, geophysical data were analyzed and interpreted (chirp sub-bottom profiling, side-scan sonar, and multibeam bathymetry) from the Maryland Wind Energy Area (WEA). Side-scan sonar data from the WEA show three distinct acoustic intensities; each is correlated to a general bottom sediment grain size classification (muds, muddy and/or shelly sand, and sand with some gravel). Chirp sub-bottom profiles reveal the continuity and thicknesses of various depositional layers including paleochannel systems. Paleochannels consist of heterogeneous infill; creating undesirable conditions for foundation placement. This “desktop” study provides a suitability model for how the interpretation of geophysical and geotechnical data can be used to provide constraints on, and reduce uncertainties associated with, foundation location and type selection. Results from this study revealed 5 distinct subsurface units. The oldest (Unit 5) originated from Middle Pleistocene during Marine Isotope Stages (MIS) 5 & 6. The youngest (Unit 1) consists of the modern surficial sand sheet sediments which have been eroded and reworked during recent Holocene transgression. Several distinct paleochannel systems incise the study area. Though data beyond the boundaries of the study area are scarce a southeasterly channel direction along with results from previous studies suggest these systems originated from Maryland coastal bays. An integrated marine spatial planning approach identified the southernmost portions of the study area as the most unsuitable for wind energy development. Conversely, the same analysis determined that the central-eastern section of the WEA is most suitable. Correlating these data with parameters governing foundation selection revealed that piled-type foundations (either lattice or monopile) are most appropriate for the study area, although suction bucket caisson foundations cannot be definitely ruled out as a possible design solution.

Download or read book Geotechnical Parameters Important for Offshore Wind Energy in Atlantic Canada written by J. B. R. Eamer and published by . This book was released on 2022 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: "To date, a major hindrance to offshore wind energy development has been the relatively high cost of site characterization, deployment, construction, and maintenance compared to onshore wind energy or conventional power production. However, rapid technology development and innovation in all aspects of the supply chain has resulted in recent claims that "the era of subsidy-free offshore wind turbines has begun". A key component to de-risking offshore wind energy is the development of a geotechnical model involving the accurate and efficient geotechnical characterization of the marine soils that may host offshore wind infrastructure. Offshore wind-specific geotechnical modeling and characterization approaches are starting to reach maturity. This report aims to review the current methods of offshore wind geotechnical characterization and provide context for Atlantic Canada-specific soil conditions"--Introduction, page 1.

Book excerpt: The coastal zone is the host to many human activities, which have significantly increased in the last decades. However, sea level rise and more frequent storm events severely affect beaches and coastal structures, with negative consequences and dramatic impacts on coastal communities. These aspects add to typical coastal problems, like flooding and beach erosion, which already leading to large economic losses and human fatalities. Modeling is thus fundamental for an exhaustive understanding of the nearshore region in the present and future environment. Innovative tools and technologies may help to better understand coastal processes in terms of hydrodynamics, sediment transport, bed morphology, and their interaction with coastal structures. This book collects several contributions focusing on nearshore dynamics, and span among several time and spatial scales using both physical and numerical approaches. The aim is to describe the most recent advances in coastal dynamics.

Download or read book Metocean Data Management and Modeling to Support U.S. Offshore Wind Power Development in the Mid-Atlantic written by and published by . This book was released on 2012 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts to encourage more conservative electricity consumption, through public awareness campaigns and government-mandated energy efficiency standards, have consistently been overshadowed by population increase and increased standards of living, leading to higher electricity demand, year after year. Sufficient resources and technology exist to support the development of a robust offshore wind industry to help meet this rising demand, but a number of barriers unique to the U.S. have hindered progress. Addressing many of these obstacles involves resolving uncertainty issues related to development. Not only is there a general lack of data to provide stakeholders, developers, and governing authorities with sufficient information for informed decision-making for offshore wind projects, but the data that do exist are often fragmented or isolated within a particular project or application. There is an immediate need to improve the reliability of metocean data as it pertains to characterizing the offshore wind resource, and to share that and other related information in a standard format that promotes and encourages interoperability across multiple platforms associated with offshore wind development. The methodology for addressing some of these data challenges began with the evaluation of a proposed improvement to a particular atmospheric modeling system being utilized to provide wind resource data within the "Virginia Offshore Wind Advanced Technology Demonstration Site Development" project. By considering the current limitations associated with SST data acquisition and initial analyses, it was determined that the integration of higher resolution SST data would be valuable only if latency issues in the data were resolved, which would require the development of an SST forecasting mode to be coupled with the operational model. This did not prove justifiable due to the lack of significant improvements in wind speed forecasting capability. Data accessibility issues were then addressed in the development of a web mapping portal designed to dynamically display geo-referenced project results and integrate publicly-available metocean data. By utilizing best practices for data sharing and information dissemination, optimum interoperability was established through smart design and the use of standard web service protocols.
Book Synopsis On the Effect of Offshore Wind Farms on the Atmosphere and Ocean Dynamics by : Elke Ludewig
Download or read book On the Effect of Offshore Wind Farms on the Atmosphere and Ocean Dynamics written by Elke Ludewig and published by Springer. This book was released on 2014-10-31 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Renewable energy resources now play an essential role in the energy supply debate, and especially a new interest in wind energy has resulted in the intensified construction of wind farms. Thanks to the growing demand for renewable energy, offshore wind farms (OWFs) are increasingly gaining in popularity, since yields over sea are greater and more reliable than over land. Against this background it is becoming particularly urgent to determine whether and if so to what extent such OWF expansion affects our oceans and local climates. OWFs produce a downstream wind speed reduction, the so-called wind-wake effect, which impacts atmospheric boundary layers, alters local wind characteristics and in turn affects ocean dynamics. This book will help readers to understand in detail these OWF-induced changes in the atmosphere and ocean by analyzing model simulations and measurements. In this context, OWF-induced upwelling and downwelling are key aspects.

Book excerpt: The time has come for the United States to harness the headwinds facing its nascent offshore wind industry given the significant offshore wind resource potential coupled with growing coastal electricity demand. In this work, I explore interrelated atmospheric science, turbine technology, and offshore wind policy challenges with the objective to elucidate opportunities to overcome the reoccurring industry challenge of wind farm underperformance bias (WFUB). Rotor-layer wind shear and turbine available power uncertainties prior to wind farm construction may contribute to high pre-construction energy yield uncertainty, thus WFUB. To help understand this uncertainty, I introduce a novel wind profile classification algorithm to account for non-standard profiles that deviate from near power law conditions, and a method to comprehensively assess rotor-layer stability. I use these methods to characterize offshore Doppler wind lidar measurements in the Mid-Atlantic Bight and in front of a 2 MW turbine in coastal Delaware.

Book Synopsis The Atlantic Offshore Wind Power Potential in PJM by : Scott Baker
Download or read book The Atlantic Offshore Wind Power Potential in PJM written by Scott Baker and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous offshore wind power resource assessments have done an adequate job of incorporating wind speeds, bathymetry, and ocean use conflicts that impact where offshore development is best suited. While these assessments have done well to inform developers and policy makers of the size of the resource, the methods for offshore wind power assessments can be improved. Specifically, this paper addresses the need for a regional, detailed exclusion analysis of the mid-Atlantic Ocean that takes into account the use conflict of shipping on the Outer Continental Shelf. In addition, this study is unique in that it calculates the offshore wind power resource within the footprint of the regional transmission organization and wholesale electricity market operator, PJM Interconnection (PJM). Using public databases on use conflicts and geographic information systems (GIS) software, the total suitable area for offshore wind development is identified. Then, modeled wind speeds, a wind turbine power output curve, and assumptions about turbine spacing and acceptable losses are used to calculate the amount of offshore wind power able to be produced within the PJM offshore area. The findings suggest that there is enough offshore wind power, out to 1,000 meters depth, to supply 97.9 Gigawatts of power on average and over 850,000 Gigawatt hours of annual energy. This is enough power to supply over 120% of the average load and over 100% of the total annual energy consumption in PJM's service territory -- an area composed of 13 states, the District of Columbia, and 54 million people. This very large renewable resource could be used to meet state renewable energy mandates and lower carbon emissions in the Mid-Atlantic region.

Book excerpt: This study, supported by the US Department of Energy, Wind Powering America Program, Maryland Department of Natural Resources and Chesapeake Bay Foundation, analyzed barriers to wind energy development in the Mid-Atlantic region along with options for overcoming or mitigating them. The Mid-Atlantic States including Delaware, Maryland, North Carolina and Virginia, have excellent wind energy potential and growing demand for electricity, but only two utility-scale projects have been installed to date. Reasons for this apathetic development of wind resources were analyzed and quantified for four markets. Specific applications are: 1) Appalachian mountain ridgeline sites, 2) on coastal plains and peninsulas, 3) at shallow water sites in Delaware and Chesapeake Bays, Albemarle and Pamlico Sounds, and 4) at deeper water sites off the Atlantic coast. Each market has distinctly different opportunities and barriers. The primary barriers to wind development described in this report can be grouped into four categories; state policy and regulatory issues, wind resource technical uncertainty, economic viability, and public interest in environmental issues. The properties of these typologies are not mutually independent and do interact. The report concluded that there are no insurmountable barriers to land-based wind energy projects and they could be economically viable today. Likewise potential sites in sheltered shallow waters in regional bay and sounds have been largely overlooked but could be viable currently. Offshore ocean-based applications face higher costs and technical and wind resource uncertainties. The ongoing research and development program, revision of state incentive policies, additional wind measurement efforts, transmission system expansion, environmental baseline studies and outreach to private developers and stakeholders are needed to reduce barriers to wind energy development.
