The cost of the overall construction of the float is very high and the difficulty of manufacture and installation is also high. Simultaneously, integral kicking block structural dimension is big, uses a period of time damaged can appear, causes the aquatic buoyancy of umbilical to reduce, at this moment needs to supply the new kicking block of installation, consequently needs a kind of buoyancy piece that is different from integral cover installation on the umbilical, can follow-up installation use urgently.
