Subsea Buoyancy
Evergreen can make buoyancy material used for subsea up to 7000m. Product of different opplications buoyancys are manufactured upon our advance subsea buoyancy material. We can make subsurface mooring buoys , cable float, pipeline buoys, ROV buoyancy module , special buoys, and other synmatic foam products.
Our high-performance subsea buoyancy material and synmatic foam have the following performance.
