The entire application of a mooring buoy works in such a way that the buoy is floating while the ships are moored to a very firm support without using the anchor system of halting a ship. In some parts of the world, mooring buoys are also used to moor boats and ships away from areas where coral reefs thrive.
Ships using mooring buoys to protect coral reefs do so because when the traditional types of anchors are used, they tend to dig and uproot the coral that lie deeply under the water surface. This would cause a huge loss to the marine ecosystem. By using a mooring buoy, two purposes are served – the ships are moored appropriately and the loss to the marine life-forms is prevented. Such mooring buoys in coral reef areas are located mainly in Australia, Asia and also in some parts of the United States.
