Umbilical Cable Floats
Umbilical Cable Floats provide distributed buoyancy for platform-to-subsea umbilical cable applications. Available as integral or secondary clamps, these modules can be customized to fit any size or configuration of umbilical cable.
Underwater Robotic ROV Float
Solid buoyancy materials play a vital role in the design of ROV floats. Its main function is to provide buoyancy so that the robot can move and operate stably underwater. Solid buoyancy materials offer greater stability and reliability than traditional foamed buoyancy materials.
Subsea Spherical Buoys
Subsea Spherical Buoys are resistant to deep sea water corrosion and have good weather resistance. Water absorption rate ≤1%, providing stable buoyancy under large water pressure to ensure safe work. It can be machine processed according to custom demand.
Underwater Buoyancy Modules
Modular floats are the most versatile method for offshore applications, they come in a variety of standard sizes and can be customized for the required buoyancy as well as the depth of application. This product provides an easy way to meet buoyancy requirements.
Large ROV Floats Modules
The large underwater robotic float is an important piece of equipment for seabed work. It is capable of performing lots of tasks, such as subsea cable laying, seabed mining, and seabed exploration, thus improving the efficiency of maritime exploration and seabed operations.
Custom Solid Buoyant Material
Such a solid buoyant material is also called hollow glass beads. It is characterized by high strength and low water absorption, and plays a crucial role in the design of ROV floats and AUV buoys, which enable robots to move and operate stably underwater.
