  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • 2013 to be Record Year for Offshore Wind

    Offshore wind power installations are on track to hit a seventh consecutive annual record in 2013. Developers added 1,080 megawatts of generating capacity in the first half of the year, expanding the world total by 20 percent in just six months. Fifteen countries host some 6,500 megawatts of offshore wind capacity. Before the year is out, the world total should exceed 7,100 megawatts. Although ...

  • Experience with and strategies for public involvement in offshore wind projects

    The paper describes and analyses different models for public involvement, based on experience from offshore projects in Denmark (especially Middelgrunden) and Sweden (Karlskrona Vindkraft Offshore). The public likely to be concerned by offshore wind energy projects must be informed and consulted as part of the Environmental Impact Assessment (EIA). However, as member states individually define ...

  • Prospect of offshore wind energy development in Japan

    In Japan, the cumulative capacity of wind turbine generation systems on land has increased steadily in recent years. To install a large number of wind turbines has inherent problems such as shortage of suitable land, and inadequate infrastructure such as power cables and roads. The necessity for development of offshore wind turbine generation systems has been recognised based on the above ...

  • Logistics Planning in Offshore Wind Farm Development

    “In the offshore wind power industry, logistics planning is the dominant driver to avoiding costly mistakes,” highlighted Jim Lanard, President, Offshore Wind Development Coalition. The technologies needed to set up offshore wind farms are available in the US, and what is needed the most is a focus on logistics that would make them happen efficiently, he added.  A speaker at the ...

  • Gamesa, Northrop Grumman to collaborate in offshore wind

    Spanish wind technology giant Gamesa and U.S. defense contractor Northrop Grumman (Los Angeles, CA) have signed an agreement under which the two companies will collaborate in the development of technologies for offshore wind facilities. Under the terms of the agreement, Northrop Grumman Shipbuilding will apply its experience in heavy load logistics, systems performance, and reliability ...

  • Offshore Wind Development Picking Up Pace

    Wind power is the world’s leading source of renewable electricity, excluding hydropower, with 238,000 megawatts of capacity installed at the start of 2012. Thus far, almost all of this wind power has been tapped on land; worldwide just 4,600 megawatts of offshore wind farms were operating as of mid-2012. Offshore wind capacity is growing quickly, however, expanding nearly six-fold ...

  • Innovation risk slows offshore wind foundation development

    As offshore wind technology develops ever more gigantic machines further from shore into deeper waters, it is common wisdom that new foundation technologies are needed. But are they? Monopile, and some jacket foundations, still dominate the offshore wind market in commercial operation. Prototype floating foundations are performing well in demo or pilot projects, but scaling up is only ...

  • Tidal influence on offshore wind fields and resource predictions

    The rise and fall of the sea surface due to tides effectively moves an offshore wind turbine hub through the wind shear profile. This effect is quantified using measured data from three offshore UK sites. Statistical evidence of the influence of tide on mean wind speed and turbulence is presented. The implications of this effect for predicting offshore wind resource are outlined.Keywords: Tidal, ...

  • The effect of ocean waves on offshore wind turbines

    The Ocean has a varying surface roughness where the roughness length is determined by the characteristics of the waves. In this paper, a method is established where the roughness length of the ocean is calculated from the wind speed and the fetch length. The fetch length depends on the wind direction and a case study is performed for a wind turbine exposed to wind blowing in two opposite ...

  • Europe`s onshore and offshore wind energy potential

    The exploitation of renewable energy sources can help the European Union meet many of its environmental and energy policy goals, including its obligation to reduce greenhouse gases under the Kyoto Protocol (EC, 2002a) and the aim of securing its energy supply (EC, 2002b; EC, 2005). As early as 1997, the European Union set an ambitious 2010 indicative target of 12 % for the contribution of ...

  • Multi-megawatt wind turbines for offshore use: aspects of Life Cycle Assessment

    Life Cycle Assessment (LCA) is an instrument to quantify environmental impacts of the entire energy supply chain. According to the LCA, an appropriate indicator system should comprise all steps of a system's life cycle: production, operational and disposal processes ("cradle-to-grave"). Cumulative Energy Demand (CED) might be seen as one part of LCA as far as the depletion of energy resources in ...

  • Proposed offshore wind farm consents process in the UK: some considerations

    The objectives of the study were to define the full details of the consenting process for offshore wind farms in territorial waters (in England and Wales) and to develop guidance aimed primarily at developers outlining the consenting process in its entirety. Conclusions included: the formalisation of available routes to consents for developers; the formalisation of the requirement for a DTI ...

  • Maintenance Manager to control operation and maintenance of offshore wind farms

    Maintenance of wind farms is of increasing importance. Especially in remote areas, where logistics and accessibility are restricted, costs of preventive as well as corrective maintenance form a substantial part of the costs of electricity. The importance of a tool that assists in feedback to the design, failure logging, configuration control and maintenance planning is evident. This paper ...

  • US launches multi-million $ plan to kick start offshore wind industry

    The new strategy from the Obama administration could challenge the UK’s place as world’s leading offshore wind energy hub. The US government unveiled yesterday a coordinated strategic plan to accelerate the development of offshore wind energy in a move that could ultimately challenge the UK's position as the world's leading offshore wind hub. Interior secretary Ken Salazar and energy ...

  • Offshore wind installation vessel capacity to tighten after 2020

    The existing fleet of turbine and foundation installation vessels is well suited to serve the European offshore wind market in the short and mid-term but it will not be sufficient to support installation demand after 2020, Michael Guldbrandtsen, senior consultant at MAKE Consulting, told Wind Energy Update. The next 2-3 years will continue to be dominated by orders for jack-up ...

  • Pricing mechanisms for offshore wind electricity in EU member states

    The aim of the study was to evaluate the pricing mechanisms for offshore wind electricity in those EU Member States (MS) possessing an important offshore wind resource and, on this basis, to determine the economic scenario faced by potential investors in the sector. The economic and energy policy framework of each MS was reviewed to establish the main factors determining the final price accorded ...

  • Renewable energy production issues with the Cape Cod offshore wind energy programme

    This paper evaluates the first offshore wind farm proposal in the USA. It is being put forward by Cape Wind Associates, a Boston-based firm that wishes to build 170 turbines five miles offshore in Nantucket Sound. The proposed development would supply up to 95% Cape Cod's energy needs and 2% of the energy requirements for the eastern New England region, preventing the need for additional fossil ...
