==Classification==
Current VLFS designs for VLFS fall into two categories: [[semi-submersible]], and [[Pontoon bridge|pontoon]].
 
The semi-submersible-type VLFS has a raised platform above sea level using column tubes; it is more suitable for deployment in high seas with large waves. In open sea, where the waves are relatively large, the semi-submersible VLFS minimizes the effects of waves while maintaining a constant buoyant force. Semi-submersible types are used for [[petroleum]] exploration in deep waters. They are fixed in place by column tubes, piles, or other bracing systems.
