A bollard setting and installation system for efficiently installing a bollard wall without any restrictions relating to proximity to water or flood plains. The bollard setting and installation system generally includes a setting frame which is positioned on a ground surface. A plurality of bollards is positioned on the setting frame in a desired spacing and orientation to form a bollard wall. A vehicle having a vehicle arm connected to a lifting frame is positioned such that the bollards are secured to the lifting frame by clamps in the desired spacing and orientation. The vehicle may then move the lifting frame to position the lower ends of the bollards in an opening in the ground surface. Concrete may be poured to encapsulate the lower ends of the bollards. The lifting frame may then be removed, with the bollard wall being free-standing in the ground surface.

A system for controlling a motion compensated pile guide for a floating vessel comprises a pile guide for guiding a monopile in its longitudinal direction during driving the monopile into a seabed, an actuator for moving the pile guide in horizontal direction with respect to a vessel to which the pile guide is mounted, a control unit for controlling the actuator, which control unit is configured for compensating motion of the vessel to which the pile guide is mounted so as to maintain the horizontal position of the pile guide during driving a monopile into a seabed, a first sensor for determining an inclination angle of a monopile with respect to the vertical during driving the monopile into a seabed, and a second sensor for determining magnitude and direction of an actual force of a monopile onto the pile guide during driving the monopile into a seabed. The control unit is configured to determine a desired force of the pile guide onto the monopile for minimizing the inclination angle when determined by the first sensor, and to control the actuator for moving the pile guide opposite to the direction of the actual force when the desired force is larger than the actual force and in the same direction as the actual force when the actual force is larger than the desired force.
