Navantia has started cutting steel at the Puerto Real shipyard for the electric substation of the UK’s East Anglia One offshore wind farm owned by Iberdrola. The first steel cut corresponds to the Cable Deck.

The scope of the contract includes the construction of a topside module and its jacket foundation at the Puerto Real shipyard, as well as the offshore support for its connection and commissioning in the North Sea. For Navantia, estimates reckon this will represent work for some 350 people although there will be “peaks of up to 600” over the coming 18 months.

 

This new contract, along with the contract to manufacture 42 jackets at the Ría de Ferrol yard for the same wind farm, represents a huge step forward in consolidating Navantia’s presence in the offshore wind sector, following on from the contracts already executed for the Wikinger farm that have been satisfactorily completed for Iberdrola.

East Anglia One is one of the largest offshore wind farms in the world

Thanks to an investment of almost €3bn, East Anglia One will be one of the largest offshore wind farms in the world when it enters into operation in 2020. Iberdrola’s installation will be able to cover the electrical power supply for over 500,000 UK homes.

With a contract value of almost €65m, its scope includes the construction of the substation, its support structure (jacket) and the offshore support for connection and commissioning in the North Sea. Construction is taking place at the Puerto Real shipyard in Cadiz.

This wind farm, the third such contract to be commissioned by Iberdrola worldwide, will be equipped with the largest wind turbines in existence to date, with a per unit capacity of 7 MW and a total height of 235 m.

The size of this initiative is unprecedented in Spain’s renewable industry. For example, the wind farm will occupy more than 300 km2 and will have an 85 km cable to carry the energy to the mainland. The surface area of the substation will be 1,144 m2 and each wind turbine blade will be 75 metres long.
East Anglia One is the third project to be undertaken by Iberdrola in the offshore wind power sector. Projects already underway in the UK by the company include the 389 MW West of Duddon Sands wind farm and the 350 MW Wikinger farm which is under construction phase.

Apart from the contract to construct the East Anglia One substation, Navantia’s Andalusian shipyards have also constructed the offshore substation for the Wikinger wind farm, being developed by Iberdrola in the German Baltic Sea, which was delivered in August 2016 and is now installed on site.

Siemens Wind Power will, for the first time, provide complete offshore wind farm solutions including foundations for the EnBW Hohe See offshore wind farm Hohe See owner EnBW has now made a final investment decision for its 497 MW offshore wind farm Starting in early 2018 the large offshore wind farm will be installed at a site 90 km north of the German island Borkum in the North Sea at water depths of up to 40 m.

The 71 wind turbines of the type SWT-7.0-154 rated at 7 MW each will be manufactured at Siemens’ new nacelle plant in Cuxhaven beginning in mid-2018 and will be shipped to the project harbor in early 2019. The blades will be shipped from factories in Hull, UK, and Aalborg, Denmark. Commissioning is planned for the third quarter of 2019. The wind power plant will generate enough power to supply 560,000 households with clean renewable energy.

 

In 2016 Siemens began with the development of project-specific solutions for the foundations of EnBW Hohe See wind power plant with a preliminary project. The result was the development of a large monopile design with a length of up to 80 meters and a weight of up to 1,500 tons to anchor the wind turbines solidly into the sea bed. Siemens has more than 25 years of experience with offshore projects starting with Vindeby offshore project in Denmark, commissioned in 1991.

For EnBW Hohe See, Siemens is partnering with logistics specialist GeoSea. The company of the Deme Group will also deliver the foundations including monopiles and transition pieces. With its extended scope Siemens helped to mitigate risk-exposure to the investors significantly. The integrated design and installation approach together with the complete solution including turbines, towers, transition pieces and foundations provides investors with maximum security and confidence regarding the financing and completion of this project.

After commissioning, Siemens will perform service and maintenance of the turbines for a period of five years. Grid connection will be established via the “BorWin 3“ high-voltage DC link and „BorWin Gamma“ converter platform to be installed by Siemens for grid operator Tennet.

ScottishPower Renewables has agreed a contract with Nexans and Darlington-based DeepOcean to fabricate and install the export cables for the East Anglia ONE offshore windfarm. The contract will safeguard 150 jobs in Darlington and the surrounding area, as well as enabling DeepOcean to offer significant opportunities to the UK supply chain.

The cables will carry the electricity from the 714 MW windfarm onshore in Suffolk, via two 85 km submarine cables with embedded fibre optics. Delivery of the cables will begin in summer 2018.

The contract award will also allow DeepOcean to maintain its policy of recruiting STEM graduates into the UK workforce. This policy has enabled DeepOcean to increase its skill base in the complex engineering and execution of demanding offshore projects on a year by year basis.

 

East Anglia ONE is a £2.5 billion offshore windfarm, which will generate enough renewable energy to power 500,000 homes per year. ScottishPower Renewables is on target to deliver more than 50% of UK content across the life of the project.

The project will be the most cost efficient offshore windfarm ever to confirm construction, and is leading the way to meet the UK Government’s cost reduction targets. The price of £119 MWh was secured after a competitive auction process run by the Government, and is more than 15% lower than other offshore wind projects in construction elsewhere in the UK.

Iberdrola and Navantia have signed, in London, the contract to construct the electrical substation for the East Anglia 1 offshore wind farm in the UK. The scope of the contract includes the construction of one module, its jacket support structure, at the Puerto Real shipyard and the offshore support for its connection and commissioning in the North Sea.

The contract will involve an estimated workforce of on average 350 people, however there will be peaks of up to 600 over the next two years. The works will start shortly and will conclude in around 2 years’ time with the installation of the jacket and the module in the North Sea.

 

Navantia is expected to collaborate with and support Iberdrola over the coming months in the initial project phase, in the development of the engineering works as well as in other activities with the aim of guaranteeing delivery periods and the quality of the supplies from the main collaborators. Manufacturing will start next spring.

The East Anglia 1 wind farm is situated in the south-eastern area of the North Sea, some 45 km south-east of the town of Lowestoft and covers an area of some 300km2. East Anglia 1 comprises 102 wind turbines with a total installed capacity of up to 714 MW. The wind turbines will be assembled on jacket-type steel structures.

Navantia also has a pre-agreement in place, expected to be signed soon, to construct 42 jackets that will support the wind turbines. These parts will be manufactured at the Navantia shipyard in Fene, Ferrol.

The wind farm is equipped with an electric substation (OSS) and two AC circuits connected to an onshore substation in Bramford (north of Ipswich), adjacent to the existing National Grid substation. The module consists of four housings supported by 4 feet covering a surface of 22 x 26 m. The total estimated weight of the module is around 3,500 tonnes.

The total height of the jacket is 58 m, including 12 J-tubes for the cables array and a further 2 for the transmission cable. It will also be equipped with two boat landings so that vessels can moor to the substation. The total weight of the jacket structure is approximately 2,400 tonnes and that of the 4 piles is 1,167 tonnes.

Siemens has received an order for the maintenance and upkeep of the Offshore Substation (OSS) and turbine substructures of the Veja Mate offshore wind farm. Siemens will install 67 six MW class wind turbines for the 400 MW offshore wind farm and connect it to land with the BorWin2 DC grid connection. This grid connection can transmit a total of just under 800 MW of clean wind energy

Siemens will implement a complete service concept to meet the maintenance needs of projects far offshore such as the Veja Mate offshore wind farm. The exact scope of supply includes the scheduled maintenance and upkeep of the OSS, the 67 transition pieces of the wind turbines, as well as the inspection of their underwater structures. A transition piece is the part that lies between a monopile foundation and the tower of an offshore wind turbine.

 

Siemens will also build and operate an OCC in Hamburg, equipped with SCADA software provided by Veja Mate for the operational control of the offshore wind farm. The company will be responsible for the entire offshore logistics, correcting faults on site and using EPCI contractor supplied spare parts and consumables during warranty.

For the wind turbines, Siemens will provide a highly advanced logistics concept, tailored specifically for far-shore projects, that uses both a helicopter and a specially designed, purpose-built service operation vessel (SOV). To ensure increased energy production this concept allows maintenance work to be carried out at almost all times irrespective of the weather conditions or wave height.

The Veja Mate offshore wind farm is being built in the German waters of the North Sea. The wind turbines in the SWT-6.0-154 series will be installed at ocean depths between 39 and 41 meters starting in January 2017. To date, Siemens has installed four HVDC grid connections and four offshore wind farms in the German waters of the North Sea alone. Furthermore, Siemens will supply wind turbines to five offshore wind farms which are currently under construction in the German North and Baltic Sea.

El acuerdo se firmó en el Museo de la Construcción Naval (Fundación Exponav) en el Arsenal de Ferrol, por el presidente de Iberdrola, Ignacio Galán, y el presidente de Navantia, José Manuel Revuelta, en el transcurso de un acto que contó con la presencia del presidente de la Xunta de Galicia, Alberto Núñez Feijóo. / The agreement was signed at the Shipbuilding Museum (Fundación Exponav) of Ferrol's arsenal facilities, by the Chairman of Iberdrola, Ignacio Galán, and the Chairman of Navantia, José Manuel Revuelta. The event was also attended by the Chairman of the Regional Government of Galicia, Alberto Nuñez Feijóo.

Iberdrola has awarded Navantia and Windar a contract worth slightly over €120 million for the East Anglia One offshore wind farm, which the electricity group is currently developing in British waters of the North Sea. With 714 MW capacity, it is the largest renewable energy project ever undertaken by a Spanish company.

The agreement provides for the supply of foundations for the East Anglia One wind turbines. Navantia will produce 34 state-of-the-art jackets at its shipyard in Fene (Spain), and Windar will be forging the jacket piles at its facilities in Avilés (Spain).

This commission comes just weeks after Navantia and Windar successfully delivered, on time and according to strict quality specifications, 29 jackets and 116 piles for the Wikinger offshore wind farm being built by Iberdrola in the Baltic Sea.

Through this new award Iberdrola enables Navantia and Windar to maintain jobs at their respective facilities. Between March 2017 and June 2018, some 850,000 man-hours will be provided for, meaning an average of 600/700 jobs with up to 1,300 people working at the busiest times. Also, local and international suppliers stand to benefit, as was the case with the Wikinger project.

East Anglia One, one of the world’s largest offshore wind farms

East Anglia One will be one of the world’s largest offshore wind farms by the time it is commissioned in 2020, with an installed capacity of 714 MW, enough to supply clean energy to over 500,000 average UK households.

It is the largest renewable energy project carried out by a Spanish company to date, with total investment valued at £2.5 billion, and a clear demonstration of Iberdrola’s commitment to combating climate change.

Within the procurement process for East Anglia One, Iberdrola has already awarded Siemens the supply of 102 wind turbines, with a unit capacity of 7 MW.
The scale of this initiative is unprecedented in the Spanish renewable industry. For example, the wind farm site will cover an area of more than 300 km2, the export cable that will carry energy to the mainland will be 85 km long; the substation will cover a surface area of 1,144 m2 and the wind turbine blades will be 75 m long each.

East Anglia One is the third offshore wind project to be undertaken by Iberdrola. West of Duddon Sands (389 MW) is currently in operation in the UK and Wikinger (350 MW) is being built in German waters of the Baltic Sea.

This new offshore initiative is part of an even more ambitious project. Iberdrola has applied for planning consent to build East Anglia Three which has 1,200 MW capacity. If approved, total offshore wind capacity at East Anglia could reach 2,000 MW.
