The low density and high strength of solid buoyancy materials can provide enough static buoyancy for heavy loads, so they are also widely used in other applications, such as Marine cables and ROV umbilical cables.
Cable floats made of solid buoyancy materials are mainly applied to Marine cables and other kinds of counterweight needs. Multiple cable floats can be installed on the cables at intervals according to the needs of providing buoyancy, so as to meet the buoyancy needs. The hitch design of this kind of floats is very convenient for taking off and installing the cables when collecting and releasing the cables. It's very easy to use.
ROV is an unmanned remotely operated vehicle with cable. The ROV is connected to the surface mother ship by umbilical cables. The umbilical cables are required to transmit power downward and two-way control signals in real time. Solid buoyancy materials also need to be installed on the ROV umbilical cable to reduce the indexing force of the umbilical cable on the ROV to maintain zero buoyancy and ensure normal and stable operation of the ROV underwater. Solid buoyancy materials for the umbilical cable not only provide buoyancy for the umbilical cable, but also protect the ROV from loss due to the breakage of the umbilical cable in the complex Marine environment.
