Very large floating structures (VLFSs) or, as some literature refers to them, very large floating platforms (VLFPs) can be constructed to create floating airports, bridges, breakwaters, piers and docks, storage facilities (for oil & natural gas), wind and solar power plants, for military purposes, to create industrial space, emergency bases, entertainment facilities (such as casinos), recreation parks, mobile offshore structures and even for habitation. Currently, different concepts have been proposed for building floating cities or huge living complexes.[1]

Overview[edit]
Unlike the top surface of vessels, that of a VLFS is used as the ground, and therefore the floating structure should provide a very large surface area. It can be constructed by joining the necessary number of floating units together. The design of the floating structure must obey safety and strength requirements, operating conditions, etc. Steel, concrete (prestressed or reinforced hybrid) or steel-concrete composite materials may be used to build the floating structure. The motions of the floating structure must be less than those allowed to ensure the safety of people and facilities on a VLFS. Generally, floating structures shall be moored at the same site for a long time.
Classification[edit]
VLFSs may be classified under two broad categories, namely the pontoon-type and the semi-submersible type. The former type is a simple box structure and features high stability, low
