Ramboll was contracted to design the turbine and substation foundations, while MT Højgaard supplied the foundations for the substations and 88 turbines.

The manufacture of turbine monopiles and transition pieces was subcontracted to Sif Group and Smulders, and the substation superstructure and foundations were subcontracted to Heerema, Bladt Industries, and Sif Group and Smulders.

Siemens obtained a €450 million contract to supply 88 wind turbines to the wind farm in 2009.

Export cable installation began in late 2010, under contract to Visser & Smith Marine Contracting, with the ships Atlantic Guardian, Team Oman, and VOS Sympathy carrying out the work.

The first turbine was installed on 3 July 2011, and began generating electricity in August 2011.

Installation of the remaining foundations and transition pieces was complete by August 2011, with Seaway Heavy Lifting carrying out the work using the Oleg Strashnov vessel.

Turbine installation was carried out by Gulf Marine Services, with the initial contract with Master Marine being terminated due to delays.

The wind farm became fully operational in late summer 2012, after installation of all the turbines was complete.

The Sheringham Shoal Offshore Wind Farm was operational by late 2011, and it officially opened on September 27, 2012, with a visit from Norway's Crown Prince Haakon and UK Secretary of State Ed Davey.

The cost of developing this massive wind farm was estimated at 10 billion Norwegian krona, which is equivalent to $1.8 billion. This significant investment paid off, as the wind farm quickly became a notable contributor to the UK's renewable energy efforts.

By June 2013, the electrical transmission assets of the wind farm were acquired by a consortium called Blue Transmission for £193 million. This deal marked a significant shift in the ownership and management of the wind farm.

Statkraft took over operations and maintenance of the wind farm from Scira in August 2013, and then Statoil took over operation from Statkraft in 2017, while also increasing its share in the proposed Dogger Bank Wind Farm.

The wind farm generated 1.2 TWh in its first year of operation, which is a remarkable feat considering the scale of the project. Its levelised cost has been estimated at £150/MWh, a figure that reflects the efficiency and effectiveness of the wind farm's design and operation.

The Sheringham Shoal Offshore Wind Farm is an impressive project with some remarkable details. The wind farm consists of 88 turbines, each with a capacity of 3.6MW.

The turbines are quite tall, standing at 80m high, with three 52m long blades. Each turbine is mounted on a tubular steel monopile that's driven 23-37m into the seabed.

The monopiles themselves are massive, weighing between 375 to 530 tonnes and ranging in length from 44m to 61m. On top of the monopile, a 22m-long transition piece is mounted, weighing around 200 tonnes.

The offshore infrastructure of the wind farm includes two 900-tonne substations, which are connected to the turbines via 132kV marine cables. These cables make landfall at Weybourne, where they're connected to the onshore substation.

The onshore substation is located near Cawston, and it feeds the power to the local 132kV UK Power Networks distribution network. From there, the power is transported to the national grid.

By generating power from the wind farm, the project helps reduce carbon dioxide emissions by 500,000 tonnes annually.

The cost of building the Sheringham Shoal offshore wind farm was significant, with a €60m contract signed with Statoil in 2008 for the supply of two offshore substations and a gas-insulated onshore substation.

AREVA was awarded this contract, which also included the supply of transformers, circuit breakers, and reactive power compensation. The total cost of this contract was €60m, which is equivalent to approximately $88.1m.

Wood Group Engineering (North Sea) was subcontracted by AREVA to design two offshore stations, adding another layer of expertise to the project.

Nexans was awarded a €24m contract in April 2008 to supply 22km of submarine export cables, spare cable, and equipment, as well as an optical-fibre cable.

When you're considering a contract, it's essential to factor in the total cost. The total cost of a contract can be broken down into several components, including the initial cost, ongoing costs, and potential costs of disputes or terminations.

The initial cost of a contract can be substantial, with some contracts requiring significant upfront payments or investments. For example, a construction contract may require a down payment of 10% to 20% of the total project cost.

Ongoing costs, such as maintenance and repair expenses, can also add up over time. In the case of a software contract, the ongoing costs may include subscription fees, support costs, and potential upgrade fees.

Potential costs of disputes or terminations can be significant and should not be overlooked. A contract dispute can result in costly legal fees, while a contract termination can result in significant penalties or losses.

In some cases, the total cost of a contract can be influenced by external factors, such as changes in market conditions or regulatory requirements. For instance, a contract for a project that requires specialized labor may become more expensive if there is a shortage of skilled workers in the area.

It's crucial to carefully review and understand all the costs associated with a contract before signing. By doing so, you can make an informed decision and avoid costly surprises down the line.
