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.
