Marine Subsea Buoyancy
General
This subsea buoyancy material products are used for oceanographic, offshore oil and gas, survey, ROV & AUV.
We have various buoyancy material used for subsea up to 7000m. Different application buoyancy products are manufactured from advanced subsea buoyancy material. We can make subsurface mooring buoys, cable floats, pipeline floaters, ROV buoyancy module, special shape buoys, and other syntactic foam products. The surface can be made by polyethylene shell and polyurethane elastomer.
