HVG OFFSHORE EQUIPMENT 0155: Mini Wave Buoy

Mini wave buoy is designed with a radar reflector. Its hull is made from glass fiber reinforced plastics and has Photoluminescence coating, which makes the buoy face less accident collision and easy to be found.

Advantages of Mini Wave Buoy

1. Safety Design: Inner of the buoy is filled with floating foam; though face severe collision accident, it won’t be soaked or sunk.
2. FRP Anti-aging Material: can be long-term used at sea; won’t be rusty; not easy to maintain luster and other aspects better than other materials.
3. Can be newly designed at the foundation of the original products according to customer’s special requirements
