Numerical investigation of the influence of the driving frequency during pile installation of tubular piles

Numerical investigation of the influence of the driving frequency during pile installation of tubular piles: Offshore and nearshore structures are predominantly founded by the use of open-ended profiles. The installation of open-ended profiles into the subsoil is usually done using the impact pile driving technique. To make the installation process more efficient, especially when considering the penetration velocity of the pile and the noise level, a new pile driving method was developed by IHC IQIP, formerly known as IHC Hydrohammer B.V. The influence of the standard driving method in comparison to the new driving technique is investigated in this contribution. This is done using the Finite Element Method (FEM) including a two-phase model for fully saturated soil.
