Grid Access – WIPOSIntegration of Renewable Energy with HVDC PLUS

WIPOSTMWind Power Offshore Substation

Advanced self-lifting Offshore Platform



Grid Access – HVDC PLUS & WIPOSBorWin2 and HelWin1 Projects

WIPOS is designed as a floating, self-lifting platform.

The Platform will be towed by tugs to its destination at sea, where the Water is about 40 meters deep.

A large heavy-duty crane vessel is not required to lift the topside onto its foundation.

The HVDC PLUS technology reduces complexity and space required for installation.
