Overview
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.
