Abstract
A heave tolerant pile guiding device for guiding a pile including a cylindrical section and above said cylindrical section a tapered section that narrows in upward direction. The device includes a frame to be mounted to a vessel having a hull subject to sea-state induced motion during installation of a pile. At least one pair of first and second pile engaging devices is arranged on the frame diametrically opposed relative to a center axis. Each pile engaging device comprises a pile engaging member and a hydraulic cylinder to move the member radially relative to the center axis. A hydraulic system includes a position control circuit and a sphincter control circuit. The sphincter control circuit is configured to operate the pair of first and second hydraulic cylinders in particular when the pile engaging members engage on the tapered section of the pile. The sphincter control circuit is a rotary flow divider.
