Method for estimating soft clay type seabed embedment by pipeline movement

The advanced procedure has been proposed to estimate higher accuracy of embedment of pipes that are installed on soft clay seabed. Numerical simulation has been adopted to investigate dynamic seabed embedment and two steps, i.e., static and dynamic analysis, were performed. In total, four empirical...

The advanced procedure has been proposed to estimate higher accuracy of embedment of pipes that are installed on soft clay seabed. Numerical simulation has been adopted to investigate dynamic seabed embedment and two steps, i.e., static and dynamic analysis, were performed. In total, four empirical curves were developed to estimate dynamic embedment including dynamic phenomena, i.e., behavior of vessel, environmental condition, and behavior of nonlinear soil.
