The Haven Facility was a Federation space station in orbit of Vesuvi VI, which was home to the Haven colony. It was used as a place for incoming ships to dock and transfer cargo.
It was disabled and left derelict due to the Vesuvi Event- the explosion of the Vesuvi star- but after the Galaxy-class USS Dauntless cleared debris from Vesuvi VI's orbit and delivered aid to the colony, it was recrewed and repaired. The fleet of freighters bringing additional aid to the colony docked here. (TNG video game: Bridge Commander)
