Dolores Esteban *, José-Santos López-Gutiérrez and Vicente Negro Research Group on Marine, Coastal and Port Environment and other Sensitive Areas, Universidad Politécnica de Madrid, E28040 Madrid, Spain; [email protected] (J.-S.L.-G.); [email protected] (V.N.) * Correspondence: [email protected] Received: 27 December 2018; Accepted: 24 January 2019; Published: 12 March 2019 Abstract: In recent years, the offshore wind industry has seen an important boost that is expected to continue in the coming years. In order for the offshore wind industry to achieve adequate development, it is essential to solve some existing uncertainties, some of which relate to foundations. These foundations are important for this type of project. As foundations represent approximately 35% of the total cost of an offshore wind project, it is essential that they receive special attention. There are different types of foundations that are used in the offshore wind industry. The most common types are steel monopiles, gravity-based structures (GBS), tripods, and jackets. However, there are some other types, such as suction caissons, tripiles, etc. For high water depths, the alternative to the previously mentioned foundations is the use of floating supports. Some offshore wind installations currently in operation have GBS-type foundations (also known as GBF: Gravity-based foundation). Although this typology has not been widely used until now, there is research that has highlighted its advantages over other types of foundation for both small and large water depth sites. There are no doubts over the importance of GBS.

    Wind power is an integral part of the UK Government’s climate change initiative; with the recognition that offshore wind power in particular has the potential to generate a significant amount of the energy needed by the UK itself in coming years. The London Array project forms part of a 7 gigawatt series of projects in the UK, which when complete will provide the energy equivalent to the needs of 7% of the UK¥. Supplying coatings to the London Array is the latest step in AkzoNobel’s experience in the offshore wind power market.

Kongedybet Hollænderdybet Middelgrunden Saltholm Flak 2 From Idea to Reality The idea of the Middelgrunden wind project was born in a group of visionary people in Copenhagen already in 1993. However it took seven years and a lot of work before the first cooperatively owned offshore wind farm became a reality. Today the 40 MW wind farm with twenty modern 2 MW wind turbines developed by the Middelgrunden Wind Turbine Cooperative and Copenhagen Energy Wind is producing electricity for more than 40,000 households in Copenhagen. In 1996 the local association Copenhagen Environment and Energy Office took the initiative of forming a working group for placing turbines on the Middelgrunden shoal and a proposal with 27 turbines was presented to the public. At that time the Danish Energy Authority had mapped the Middelgrunden shoal as a potential site for wind development, but it was not given high priority by the civil servants and the power utility.

  • A New Era for Wind Power in the United States
    Chapter 3 Wind Vision: A New Era for Wind Power in the United States 1 Photo from iStock 7943575 1 This page is intentionally left blank 3 Impacts of the Wind Vision Summary Chapter 3 of the Wind Vision identifies and quantifies an array of impacts associated with continued deployment of wind energy. This 3 | Summary Chapter chapter provides a detailed accounting of the methods applied and results from this work. Costs, benefits, and other impacts are assessed for a future scenario that is consistent with economic modeling outcomes detailed in Chapter 1 of the Wind Vision, as well as exist- ing industry construction and manufacturing capacity, and past research. Impacts reported here are intended to facilitate informed discus- sions of the broad-based value of wind energy as part of the nation’s electricity future. The primary tool used to evaluate impacts is the National Renewable Energy Laboratory’s (NREL’s) Regional Energy Deployment System (ReEDS) model. ReEDS is a capacity expan- sion model that simulates the construction and operation of generation and transmission capacity to meet electricity demand. In addition to the ReEDS model, other methods are applied to analyze and quantify additional impacts. Modeling analysis is focused on the Wind Vision Study Scenario (referred to as the Study Scenario) and the Baseline Scenario. The Study Scenario is defined as wind penetration, as a share of annual end-use electricity demand, of 10% by 2020, 20% by 2030, and 35% by 2050. In contrast, the Baseline Scenario holds the installed capacity of wind constant at levels observed through year-end 2013.

  • Prime Minister David Cameron Inaugurates World's
    Press Release 4 July 2013 Prime Minister David Cameron inaugurates world’s largest offshore wind farm 630MW London Array powering half a million UK homes DONG Energy, E.ON and Masdar today, (4 July 2013) officially opened the world’s largest offshore wind farm, London Array, at a ceremony attended by Prime Minister David Cameron, alongside other dignitaries. Over 350 people attended the inauguration at Turner Contemporary in Margate, Kent. London Array, the 630MW offshore wind farm located in the Outer Thames Estuary, first started generating power in October 2012. The 175th turbine was bought online in March 2013 and London Array is now celebrating the completion and full operation of the site, which could supply around 500,000 UK homes with electricity each year. Construction began in July 2009 when work started to build a new onshore substation on the north Kent coast to flow the energy generated by London Array straight into the national grid. Offshore the first foundation was installed in March 2011; the 175th and final Siemens 3.6MW turbine was installed on time in December 2012. Over 75 organisations have helped to build London Array with over 6,700 individuals involved. Speaking at the launch event, Prime Minister, David Cameron said: "This is a great day for Kent and a great day for Britain. London Array has been built by some of the bravest seamen, the most talented engineers and hardest workers. It will bring benefits to Kent for years to come." 1/3 Brent Cheshire, UK Country Chairman, DONG Energy said: “With the addition of London Array, DONG Energy has now installed enough offshore wind in the UK to power 1 million homes.
