A method of installing foundation elements, in particular (mono)piles having a diameter of five meters or more, in an underwater ground formation includes lowering a leader from a surface vessel with at least the tip of the leader into the water, and lowering a foundation element and/or a noise mitigation screen along the leader.

Method of and system for installing foundation elements in an underwater ground formation

A marine J-lay pipelaying system for use on a vessel for laying an offshore pipeline has a J-lay tower, a pipe connecting station, wherein said pipe section is connected to the previously launched pipeline, and J-lay tower bearing means which allow for the pivoting of the J-lay tower with respect to the vessel. The J-lay tower has a free-pivotal mode wherein the J-lay tower is freely pivotable with respect to the vessel so that the J-lay tower has an orientation independent from sea-state induced vessel motions. A pipe section loader is moveable between a loading position, wherein a new pipe section is received, and a erected position, wherein the new pipe section is aligned with the J-lay tower; The pipe section loader is provided with an automatic synchronizing system which&#x2014;when the pipe section loader is moved from its loading position to its erected position&#x2014;causes a synchronised pivotal motion of the pipe section loader with respect to the J-lay tower in its free-pivotal mode&#x2014;at the latest as the pipe section loader reaches its erected position&#x2014;, so that the new pipe section is aligned with the J-lay tower is in its free-pivotal mode.
