Cocobuoyancy’s products mainly focus on ROV/AUV floats, umbilical cord/cable floats, riser floats, navigation buoys, platform floats, etc., and can also be customized according to customer requirements.
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.
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 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.
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.
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.
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.
