PC Floating Pontoon
The use of prestressed concrete (PC) in floating wharfs controls tension stress on the concrete, which comes from waves or sectional water pressure, in combination with prestressed steel in the upper and lower slabs and side walls. This gives a PC Floating Pontoon high durability under the severe marine environment. PC Floating Pontoons made with light-weight concrete have more buoyancy and allow the height of the structure to be reduced.
Features
- A PC Floating Pontoon has more durability than a reinforced-concrete (RC) wharf because prestressing suppresses cracking.
- The diameter of mooring chains and mooring piles can be reduced because the PC structure can be constructed with thinner slabs and walls than those of a RC structure.
- A PC Floating Pontoon has flexibility in the choice of construction location, at a dry-dock, floating-dock, or pier.
- Larger PC Floating Pontoons can be constructed at sea or in a dry-dock by connecting smaller PC Floating Pontoons with PC steel.
- The life cycle cost of a PC Floating Pontoon can be reduced due to a maintenance cost lower than that of a steel wharf.
