.... Then the monitoring data obtained during vibro driving were used adjust the soil model used for the initial simulation and to derive the pile capacity. Next the monitoring data for the Beginning of Restrike and the End of Impact Driving were used to assess the capacity yet again. The results as well as the soil...

... Abstract As vibratory driving is increasingly used to install offshore foundations, especially for offshore windfarms, an accurate soil model is key to reliable pile driving predictions and thus to improved project planning and execution. During the pile driving, the soil properties, and thus...

Use of an appropriate soil model is essential for accurate determination of the fatigue damage. The American Petroleum Institute...
