Abstract: The invention relates to a method of installing a foundation element, in particular a (mono)pile, in a ground formation by means of a driver, comprising driving the foundation element into the ground formation by means of blows delivered by the driver to the foundation element, estimating or measuring stress waves that are generated by the blows and reflected from the tip of the foundation element, and, if a reflected stress wave is a tensile stress wave, reducing the blow energy.

Abstract: A method of and system for installing a foundation element, in particular a (mono)pile, in a hard underwater ground formation uses a driver. The method comprises the steps of placing a foundation element on the underwater ground formation, placing a screen for reducing noise input from the driver, driving the foundation element into the ground formation by means of the driver while the screen is positioned about the foundation element, and attenuating noise transfer from the underwater ground formation to the outer wall of the screen during at least part of the driving.
