Presented at the National Maritime Conference in Bremerhaven, the new transmission technology can be used for platforms which are much smaller and more compact unlike large central converter platforms to connect these plants to grid.
The company plans to further advance the transmission technology which enables connections of several platforms sequentially in a wind farm to allow transmission of 1.2GW of electricity to an onshore substation.
Siemens expects the new solution to have reduced costs and is also more efficient than the approach used with conventional platforms.
The structures of the platforms, which house the transmission technology, is reduced by four-fifths, and the weight is cut by two-thirds, thus reducing costs by more than 30%.
Siemens energy management division CEO Jan Mrosik said: "Our new solution will play a major role in decreasing the cost of offshore wind power below ten cents per kilowatt hour by 2020.
"This is how we plan to make the direct-current technology used in Germany more interesting to other markets, too."
The solution is also expected to increase transmission capacity by one-third and reduce transmission losses fall by one-fifth, marking a step ahead in significantly reducing the cost of offshore wind power.
Siemens said the technology, which is based on encapsulated high-voltage electrical equipment, replaces the current air-insulated transistor modules with diode rectifier units.
The transmission technology is planned to be market ready, potentially in Germany and the UK, by June next year, reports ReNews.
