Working Principle  

The principle of a Marine scupper is to use gravity to allow water to flow out of the ship by controlling the ship's drainage valves. The scupper is designed to facilitate the natural concentration and outflow of water to ensure the safety and stability of the ship. However, in the actual situation, it is also necessary to pay attention to the impact of external factors such as wind and waves on the scupper, and take appropriate measures in time to ensure the safety of the ship.
