A pile driving system comprises a lifting element attached or attachable to a hoisting cable of a crane, a pile driver which is mounted to the lifting element and movable with respect to the lifting element in a pile driving direction and a brake for braking a movement of the pile driver with respect to the lifting element. The brake comprises cooperating sliding members at the lifting element and the pile driver, which sliding members are pressed against each other in a direction extending transversely to their mutual sliding direction.

Pile driving system

A template for installing piles underwater includes a template frame and pile guides having parallel pile guide centerlines and being fixed to the template frame. Each pile guide has a pile guide frame that surrounds a passageway configured for passing a pile therethrough. Each pile guide frame includes upper and lower ends. Each pile guide includes a spacer fixed to the pile guide frame and protruding into the passageway. The spacer has a pile contact surface for guiding a pile. The pile contact surface encloses an imaginary cylinder including a centerline which coincides with the pile guide centerline. In a circumferential direction about the pile guide centerline, the location of the pile contact surface shifts with respect to the corresponding pile guide frame in a direction from the lower end to the upper end thereof as seen in a direction from the template center to the pile guide centerline.
