Civil: Off shore platforms

Off shore platforms

          Off shore platforms are self contained platforms with adequate facilities for drilling,  

          derrick, drilling mud electric power, pumping equipment for the offshore construction these 

          are artificial facilities above the elevation of off shore platforms              

          Off shore platforms can be classified as              

          Fixed Off shore platforms                

          Bottom supported structures           

          Compliant platforms and floating platforms                

          Construction principles of offshore platforms              

          Selection of operational criteria                 

          Selection of environment                 

          Environmental factors            

          like Storming wind                 

          velocity Storming         

          wave height         

          Tidal conditions            

          Before analysis and design of foundation it is necessary to determine the soil characters of     

          the sea shore. Capacities of the available crains will influence the operational activities of         

          platform constructions.          

          The fixed platforms can be classified into           

          Jacket or template structures           

          Gravity structures
