"As offshore wind farms are being built farther from the coast and more offshore oil and gas installations are powered from shore, there will be an increasing need for long-distance underwater power transmission in the years to come."

REpower Systems AG has successfully installed the first of six wind energy turbines for the Belgian offshore wind farm Thornton Bank. The project, located about 30 kilometers off the coast, is the first Belgian offshore wind farm. For the first of three construction phases, REpower is providing six 5-megawatt (MW) offshore turbines, adding up to a total capacity of 30 MW. Gravity based foundations were erected and carried out to sea to form the foundation for the six wind turbines in Thornton Bank. All work at sea is performed in a water depth of approximately 25 meters using jack-up drilling platforms. The 5-MW turbine which has just been erected in Belgium is the twelfth of the model installed by REpower.

"Nine European countries have today signed a major agreement to develop the world's first large-scale offshore wind energy grid in the North and Irish seas, providing a boost to the continent's fast-expanding offshore wind industry. UK energy minister Lord Hunt joined with ministers from Germany, France, Belgium, the Netherlands, Luxembourg, Denmark, Sweden and Ireland to sign the agreement on the sidelines of today's European Council meeting in Brussels."

"The new link will be particularly significant to the development of a European offshore grid able to integrate increasing levels of offshore wind and marine power in coming decades."

"Through the development of the round one and two wind farms it has become apparent that a disproportionate amount of risk lies within the installation and burial of the power cables. This project will look at the methods and equipment used during the design and specification of installation requirements for export and array cable systems in the offshore wind industry. It aims to reduce risks to the cables during installation and operation, and reduce costs for installation and operation and maintenance activities."

"This investment would result in the first factory in the UK to commercially produce offshore wind towers."

NEW YORK (MarketWatch) - Deal making and development in the wind arena continue even as the economy slows down, with the federal government moving ahead to grant leases for the U.S.'s first offshore wind projects in history and other state-based projects moving to the front burner. Comments on federal rules to govern a host of alternative energy projects proposed in federal waters off the coast of the U.S. drew about 225 responses by Monday's deadline, as the U.S. Mineral Management Service, or MMS, moves ahead with plans to lease the outer continental shelf to several companies.

But we heard what Senator Obama had to say at the DNC about outsourcing. He said "he will stop giving tax breaks to companies that are sending jobs offshore and instead give them to companies who create jobs in America".

Could this lead to a retraction of outsourcing work to economies such as India? If yes, copper demand, such as in infrastructure development, might be impacted.

Historically, wind technology has been seen on land and near offshore locations. Restrictions, such as prohibitively expensive offshore foundations to support wind turbines larger than 20 meters, may be viewed as stunting potential market growth. Now, new technology based on floating turbines may enable deeper offshore placement. The view mentioned with this news is that pushing turbines further out to sea will equalise the issue of aesthetics. However, the real issue here is can this technology deliver a useful and economic addition to the grid.

Figure 8.2.2.1 illustrates the lengths of subsea cable that may be required year by year. It is based on expected device spacings, farm layouts and likely distances from offshore substaons to shore. The final lengths required will depend on exact site layouts and separaon distances between devices as well as the method of connecon between devices, which could have dedicated connecons to the transformer or be chained together. The chart has the same profile as that of the number of devices installed, but offset as cables are purchased in advance of installaon. Export cables installed as part of a project's inial phase may be specified with sufficient capacity to accommodate later phases as well.
