Chain Support Buoys
General surface chain support buoys are extensively used in single-point mooring (SPM) systems. The chain support buoys include cylindrical buoys, chain-through buoys, and pick-up buoys.
General surface chain support buoys are constructed by resilient closed cell polyethylene /EVA foam around the inner central steelwork, covered by polyurethane (PU) outer kin. The resilient closed cell polyethylene/EVA foam core guarantees self-fendering and unsinkable even in case of damage. And self-colored polyurethane elastomer skin is resistant to abrasion and ultra violet rays degradation. For extreme service environment, the polyurethane elastomer skin can be reinforced by nylon to protective coating has higher tear strength, making the buoy long lasting and virtually maintenance free.
Step 1: Make Steel Structures
Step 2: Make Foam Core
Step 3: Polyurethane Coating
Step 4: Install End Fitting
