In the north-east corner of the Taviana map, there's a series of oil rigs. These rigs are marked to spawn high level military loot on the DayZDB Taviana map. Loot will not spawn on these oil rigs. In order for loot to spawn, a player needs to be approximately 100m away from the area on foot. Since players can only arrive at these rigs via boat, helicopter, or swimming, the possibility for loot to spawn does not exist.
Additionally, these platforms are highly dysfunctional. They are extremely glitchy and one will likely end up bleeding and breaking bones if they attempt to navigate the platform. The only way to exit the platform once you're on it is to jump from the helicopter platform (unconfirmed whether you'll live) or get extracted via helicopter.
