Breakwater Building Process
Breakwater is an installation that protects the port by preventing large sea waves from hitting the port, enabling ships to load and unload cargo to and from the ship even when the sea outside the port is rough.
Caissons, huge concrete boxes that weigh 3,000 tons and are 20m high each, are lined up to make a breakwater. The caissons are made on the ship called a "floating dock"
Pile up stones on the seabed to make the base for caissons.
Pull the caisson by the ship to the designated location.
Sink the caisson by filling it with water and pour sand in it to make it heavy so that it would not move. Close the caisson with a concrete lid.
Finally, put blocks that absorb the force of wave to complete.
