Offshore grid access with WIPOS ® from <strong>Siemens</strong><br />
� The new Wind Power Offshore substation (WIPOS) from <strong>Siemens</strong> serves as an interface between<br />
the wind turbines <strong>and</strong> the mainl<strong>and</strong><br />
� Power harvested from wind is collected <strong>and</strong> then passes through the export cables to reach the point of<br />
connection onshore<br />
� WIPOS is designed as a floating, self-lifting plat<strong>for</strong>m<br />
� The plat<strong>for</strong>m will be towed by tugs to its destination at sea where the water is about 40 meters deep<br />
� Large heavy-duty crane vessel is not needed to lift the plat<strong>for</strong>m topside onto its foundation<br />
