The materials used in Float Pontoon must meet the following requirements:

1. The density of the buoy material is as small as possible, so that its unit volume provides the largest possible buoyancy, thereby improving the working performance of the marine riser.

2. It can withstand the required hydrostatic pressure (the water pressure increases by 1 MPa for each dive depth of the marine riser 100m), and will not cause damage within the specified depth of use, that is, compressive conditions.

3. The low water absorption and bulk elastic modulus enable it to provide stable buoyancy under larger water pressure and ensure the safe and reliable operation of the marine riser. At the same time, it is necessary to consider the overall handling, load, and use of the riser and the floating material. The floating material can crack, split, lose buoyancy, and other safety and reliability issues during use. The reinforced floating material can be quite strong. For example, the surface of the floating material is coated with two layers of Kevlar glass fiber reinforced plastic and the material is reinforced inside, which can increase the strength of the floating material and can be used more safely.
