Cranefree is the trademark [1] for offshore foundations marketed by the company Seatower. [2] This technology is focused on the offshore wind sector, and is designed to avoid using heavy-lift crane vessels in order to make offshore construction less risky and costly. Furthermore, the design avoids seabed preparation (dredging and piling) in most cases.
In engineering, a foundation is the element of a structure which connects it to the ground, transferring loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics in the design of foundation elements of structures.
The Thorntonbank Wind Farm is an offshore wind farm, 30 km (19 mi) off the Belgian coast, in water ranging from 12 to 27 metres deep.
Sheringham Shoal Offshore Wind Farm is a Round 2 wind farm in North Sea off the coast of Norfolk. A lease for use of the sea bed was obtained in 2004 by Scira Offshore Energy, the development gained offshore planning consent in 2008, and was constructed 2009–2011, being officially opened in 2012.
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 Japan, France and US 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.
The Barrow Offshore Wind Farm is a 30 turbine 90MW capacity offshore wind farm in the East Irish Sea approximately 7 kilometres (4.3 mi) south west of Walney Island, near Barrow-in-Furness, Cumbria, England.
The Burbo Bank Offshore Wind Farm is a 348 MW offshore wind farm located on the Burbo Flats in Liverpool Bay on the west coast of the UK in the Irish Sea. It consists of an original 90 MW wind farm commissioned in 2007 and a 258 MW extension completed in 2017.
The Lynn and Inner Dowsing wind farms are a pair of round 1 wind farms located in the North Sea, in the shallow waters at the entrance to The Wash off the coast of Lincolnshire, England. The wind farms were developed as a single unit after planning consent was given in 2003. Construction work began in 2006 and was completed in 2009.
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.
Alpha Ventus Offshore Wind Park is Germany's first offshore wind farm. It is situated in the North Sea 45 kilometres (28 mi) north of the island of Borkum.
The Ormonde Wind Farm is a wind farm west of Barrow-in-Furness in the Irish Sea. The wind farm covers an area of 8.7 square kilometres (3.4 sq mi). It has a total capacity of 150 MW and is expected to produce around 500 GWh of electricity per year.
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.
Bladt Industries A/S is an international steel contractor specialising in large-scale and highly complex steel structures. Bladt Industries operate within three key areas of business providing steel solutions for the wind and renewable energy sector, for the oil and gas industry and for infrastructure. Bladt Industries was established in 1965 as the company Jørgen Bladt A/S.
Dudgeon Offshore Wind Farm is an offshore wind farm 32 km north of Cromer off the coast of Norfolk, in the North Sea, England. It is owned by Dudgeon Offshore Wind Limited (DOW), a subsidiary of Equinor, Masdar and Statkraft. The site is a relatively flat area of seabed between the Cromer Knoll and Inner Cromer Knoll sandbanks and is one of the furthest offshore sites around the UK.
Humber Gateway Wind Farm is an offshore wind farm 8 kilometres (5 mi) east of Spurn Point off the coast of North East Lincolnshire, in the North Sea, England; the wind farm is located in water depths around 15 metres (49 ft) and covers an area of approximately 25 square kilometres (9.7 sq mi). The wind farm became operational in June 2015.
Westermost Rough Wind Farm is an offshore wind farm 8 kilometres (5 mi) north east of Withernsea off the Holderness coast, in the North Sea, England. The farm covers an area of approximately 35 km2 (14 sq mi) with a generation capacity of approximately 210 MW. It became operational in May 2015.
Suction caissons are a form of fixed platform anchor in the form of an open bottomed tube embedded in the sediment and sealed at the top while in use so that lifting forces generate a pressure differential that holds the caisson down. They have a number of advantages over conventional offshore foundations, mainly being quicker to install than deep foundation piles and being easier to remove during decommissioning. Suction caissons are now used extensively worldwide for anchoring large offshore installations, like oil platforms, offshore drillings and accommodation platforms to the seafloor at great depths. In recent years, suction caissons have also seen usage for offshore wind turbines in shallower waters.
Rampion is an offshore wind farm developed by E.ON, now operated by RWE, off the Sussex coast in the UK. The wind farm has a capacity of 400 MW. The wind farm was commissioned in April 2018 and was the first offshore wind farm for the whole south coast of England.
A wind turbine installation vessel (WTIV) is a vessel specifically designed for the installation of offshore wind turbines. There were 16 such vessels in 2020.
Block Island Wind Farm is the first commercial offshore wind farm in the United States, located 3.8 mi (6.1 km) from Block Island, Rhode Island in the Atlantic Ocean. The five-turbine, 30 MW project was developed by Deepwater Wind, now Ørsted US Offshore Wind.
Empire Wind is a proposed utility-scale offshore wind farm on the Outer Continental Shelf Offshore New York. It will be located in Bureau of Ocean Energy Management (BOEM) lease area OCS-A 0512 in the New York Bight about 15 miles (24 km) south of Jones Beach, Long Island.
