We provide the highest quality flotation for offshore, research, commercial. Made with syntactic foam, these floats are the most reliable and cost-effective choice for ROV, AUV, and tow body flotation. Whether you are outfitting a new vehicle or tooling package, or require customized add-on buoyancy, you will get a superior product and quick turnaround.
We provide a comprehensive range of resilient foam buoys products with advance solid buoyancy material production and polymer engineering.
Our offshore buoyancy buoys generally consist of a closed-cell foam core encapsulated with tough, resistant polyurethane outer skin, combined with high-quality steelwork. We can make subsurface mooring buoys, cable floats, pipeline floaters, ROV buoyancy modules, special shape buoys, and other syntactic foam products. The out skin can be made by polyethylene shell and polyurethane elastomer.
Subsea Buoyancy Solution
The subsea buoyancy material is mainly used underwater. Based on its characteristics of low density and high pressure resistance, it mainly provides the required buoyancy for underwater operation equipment. Spray coating or protective layer treatment can be applied to the surface as required. Often manufactured and processed into floats, buoys and other counterweight products. It can also be directly machined into product parts.
It can not only meet the mechanical requirements of the product structure, but also greatly reduce the product weight and other functions. The application of this material realizes the functions that are difficult for metal structural parts to realize. At present, it has been used in underwater deep submersibles, underwater robots, etc., and can be used safely at depths of several thousand meters underwater.
