A liftboat is a self-propelled, self-elevating vessel used in support of various offshore mineral exploration and production or offshore construction activities. A liftboat has a relatively large open deck to accommodate equipment and supplies, and the capability of raising its hull clear of the water on its own legs so as to provide a stable platform from which maintenance and construction work may be conducted.
Arklow Bank Wind Park is a 25 megawatt offshore wind farm generating electrical power for the Wicklow region in Ireland. It is the first offshore wind farm in Ireland, and the world's first erection of wind turbines rated over 3 MW. It is located on the Arklow Bank, a shallow water sandbank in the Irish Sea, around 10 kilometers (6.2 mi) off the coast of Arklow with an area of 27 by 2.5 kilometres.
Greater Gabbard is a 504 MW wind farm, built on sandbanks 23 kilometres (14 mi) off the coast of Suffolk in England at a cost of £1.5 billion. It was completed on 7 September 2012 with all of the Siemens SWT3.6–107 turbines connected. Developed as a joint venture between Airtricity and Fluor, it is now jointly owned by SSE Renewables and Innogy.
In 2021 France reached a total of 18,676 megawatts (MW) installed wind power capacity placing France at that time as the world's seventh largest wind power nation by installed capacity, behind the United Kingdom and Brazil and ahead of Canada and Italy. According to the IEA the yearly wind production was 20.2 TWh in 2015, representing almost 23% of the 88.4 TWh from renewable sources in France during that year. Wind provided 4.3% of the country's electricity demand in 2015.
A floating wind turbine is an offshore wind turbine mounted on a floating structure that allows the turbine to generate electricity in water depths where fixed-foundation turbines are not feasible. Floating wind farms have the potential to significantly increase the sea area available for offshore wind farms, especially in countries with limited shallow waters, such as Spain, Portugal, Japan, France and the United States' West Coast. Locating wind farms further offshore can also reduce visual pollution, provide better accommodation for fishing and shipping lanes, and reach stronger and more consistent winds.
TIVMPI Resolution is a wind turbine installation vessel deployed to install turbines at offshore wind farms. It was the first self-elevating Turbine Installation Vessel in the world. She can raise herself on her six legs between 3 metres (10 ft) and 46 metres (151 ft) above the sea.
Offshore wind power or offshore wind energy is the generation of electricity through wind farms in bodies of water, usually at sea. There are higher wind speeds offshore than on land, so offshore farms generate more electricity per amount of capacity installed. Offshore wind farms are also less controversial than those on land, as they have less impact on people and the landscape.
Wind power in Belgium depends partially on regional governments and partially on the Belgian federal government. Wind energy producers in both the Flemish and Walloon regions get green certificates but not with the same conditions.
As of November 2023, wind power in the Netherlands has an installed capacity of 11,602 MW, 40.9% of which is based offshore. In 2022, the wind turbines provided the country with 18.37% of its electricity demand during the year. Windmills have historically played a major part in the Netherlands by providing an alternative to water driven mills.
GE Wind Energy is a branch of GE Renewable Energy, a subsidiary of General Electric. The company manufactures and sells wind turbines to the international market. In 2018, GE was the fourth largest wind turbine manufacturer in the world.
The U.S. state of Massachusetts has vast wind energy resources offshore, as well as significant resources onshore. The 2016 update to the states's Clean Energy and Climate Plan had a goal of reducing 1990 baseline greenhouse gas emissions levels by 25% by 2020. Current goals include installing 3,500 megawatts (MW) of offshore wind power in the state by 2035. However, as of Q4 2021 the state had only 120 MW of wind powered electricity generating capacity, responsible for generating 0.9% of in-state electricity production. The state has awarded contracts to two offshore projects, the 800 MW Vineyard Wind project and 804 MW Mayflower Wind project. Construction began on the Vineyard Wind 1 project on November 18, 2021, after a long fight for approval. Commonwealth Wind was selected for development in 2021, but the developer has attempted to cancel the project due to increased costs. There are eight projects planned for off the southern coast of Massachusetts, though some will deliver power to Rhode Island, Connecticut, and New York.
Triton Knoll Wind Farm is an 857 MW round 2 offshore wind farm nearing completion 33 kilometres (21 mi) off the coast of Lincolnshire, in the North Sea, England.
The Vestas V164 is a three-bladed offshore wind turbine, produced by Vestas, with a nameplate capacity of up to 10 megawatts, a world record. Vestas revealed the V164's design in 2011 with the first prototype unit operated at Østerild in northern Denmark in January 2014. The first industrial units were installed in 2016 at Burbo Bank, off the west coast of the United Kingdom. By 2021, Vestas had produced 500 of the series.
The East Anglia Array is a proposed series of offshore wind farms located around 30 miles off the east coast of East Anglia, in the North Sea, England. It has begun with the currently operational East Anglia ONE, that has been developed in partnership by ScottishPower Renewables and Vattenfall. Up to six individual projects could be set up in the area with a maximum capacity of up to 7.2 GW. The first project, East Anglia ONE at 714 MW, received planning consent in June 2014 and contracts in April 2016. Offshore construction began in 2018 and the project was commissioned in July 2020. It is expected to cost £2.5 billion.
Wind power in Virginia is in the early stages of development. In March 2015, Virginia became the first state in the United States to receive a wind energy research lease to build and operate offshore wind turbines in federal waters. Virginia has no utility scale wind farms.
Wind power is a major industry in Taiwan. Taiwan has abundant wind resources however a lack of space on land means that most major developments are offshore. As of February 2020, there were 361 installed onshore turbines and 22 offshore turbines in operation with the total installed capacity of 845.2 MW.
Vineyard Wind 1 is an offshore wind farm under construction in U.S. federal waters in the Atlantic Ocean in Bureau of Ocean Energy Management-designated Lease Area OCS-A 0520, about 13 nautical miles south of Martha's Vineyard and Nantucket, Massachusetts. The array is designed to include 62 wind turbines manufactured by GE Offshore Wind with a nameplate capacity of 804 MW combined, equivalent to the annual power use of 400,000 homes. The Massachusetts Department of Public Utilities approved the project in 2019. Construction began on November 18, 2021. In October 2023, the first turbine was installed. Power from the first turbine started flowing into the ISO New England grid on January 2, 2024. Construction is expected to be complete by the end of 2024.
Offshore wind power is in the early stages of development in the United States. In 2016, the United States Department of Energy estimated that the country has a gross resource potential of 10,800GW of offshore wind capacity, with a "technical" resource potential of 2,058GW. Offshore wind projects are under development in wind-rich areas of the East Coast, Great Lakes, and Pacific coast. The first commercial offshore wind farm, Block Island Wind Farm, began operation in 2016. As of 2017, about 30 projects totaling 24 gigawatts (GW) of potential installed capacity were being planned.
