Mooring Buoys Maintenance 


Koh Tao is renowned for world-class diving, and over 50 spectacular dive sites surround the island. To support our thriving diving economy and prevent damage to the coral reefs and marine ecosystem, mooring buoys are frequently installed and maintained. The use of dedicated mooring buoys protects divers and prevents damage caused by boats dropping anchors over the reef. 


By conducting regular mooring buoy maintenance at dive sites around the island, the health of the coral reef can be maximized, and the safety of divers exploring our amazing underwater world can be ensured. 


Mooring lines need constant inspections and maintenance. No matter how well designed they are, all will eventually break. On Koh Tao, we are fortunate to have the support and expertise of the Department of Marine and Coastal Resources (DMCR) to help us in our efforts. 

Join our mooring buoy maintenance team for the day! You’ll be introduced to mooring buoy systems and learn more about their effectiveness, bases for placement, and assist our team with their essential mooring buoy maintenance and replacement tasks.
