Abstract

Floating pontoons are the new advance method and technology in construction industry. Land issue is very common issue in various countries. Constructing on waters and in the waters is the only option to overcome the land issue. Also, the construction of the bridges and other water-based structures also can be constructed by using pontoons. Pontoons are being used in the construction since ancient time Including temporary bridges and small shelters. It’s also used by the military for the emergency time. In this study the details of the pontoons prepared from concrete, which are used in the water-based construction is discussed. Pontoons are basically exposed to three main forces i.e. water current forces, wave forces and wind forces. This study focused on the stability of the pontoons under application of the forces and helps to understand the nature of the pontoon construction with floating breakwater. Floating breakwater are used to reduce the wave intensity of the wave and reducing the intensity of the wave force. In this study the behavior of the pontoon in relative depth of waters. And observe the results of the waves and water currents on each level of the pontoon depth. The waves are stronger and produce high effect on the surface than the bottom layers of the same waters. The same wave has lowered magnitude and wave height at the bottom levels of the waters compare to the surface of the waters. Mooring system is provided from the bottom topography of the sea bed or land. By using strong cables. These cables are connected strongly between pontoon and fixed support
