Buoy external material requirements
Aug 21, 2018

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

2. Can withstand the required hydrostatic pressure (100m per submersible depth of the marine riser, water pressure increased by 1MPa), will not cause damage within the specified depth of use, that is, compression conditions;

3. Low water absorption and bulk modulus, which can provide stable buoyancy under large water pressure, ensure safe and reliable operation of marine riser, and take into account the overall treatment of riser and floating materials. Load and use, the floating material can be cracked, cracked, lost buoyancy and other safety and reliability problems during use. The enhanced floating material can be quite strong, such as coating two layers of Kevlar FRP on the surface of the floating material. The reinforcement of the material inside can increase the strength of the floating material and make it safer to use.
