Propulsion System for Mobile Offshore Wind Farm Ship

Germany’s Voith Turbo is developing a new marine propulsion system for installation into a special mobile offshore construction vessel which will be used for the installation of offshore wind farms.

Weighing over 80 tons and measuring approximately 8m high, the Voith Radial Propellers will enable the specialised vessel to sail at approximately 10 knots with a full load. The propeller’s 360 degree steering will allow highly accurate positioning even in difficult sea conditions for a vessel which has a design resembling that of a drilling platform.European construction giant STRABAG SE, which employs 76,000 people and had a turnover of €13.7bn last year, has ordered five such Voith Radial Propellers for the vessel.

The groundbreaking for a trial gravity foundation for offshore wind farms took place in Cuxhaven last week. The project is a step toward the realisation of planned wind farms in the North Sea.Completion of the trial gravity foundation is planned for spring 2010. Series production is scheduled to begin in autumn of next year. Starting in 2011, the first wind turbines for the offshore wind power plant GlobalTech I are to be set up from Cuxhaven.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
