Problems solved by technology

Separating the grippers leaves the foundation member unsupported, which represents a risk, especially when encountering strong currents or when constructing large foundation members such as monopiles with a diameter of 4 meters or more and a length of 50 meters or more

Embodiment Construction

[0021] figure 1 An embodiment of a system 1 according to the invention for installing a monopile 2 in an underwater formation 3 , such as the sea bottom, is shown. In this example, the monopile 2 has a circular cross-section and is five (5) meters in diameter, which will serve as the foundation for the wind turbine after installation is complete.

[0022] The system 1 comprises: a hydraulic pile driver 4 (eg IHC Hydraulic Hammer S-1800), which is connected to a power unit on a surface vessel such as a jack-up barge (not shown); The pile driver sleeve 5 for firmly installing the pile driver on the monopile; and the anvil (covered by the pile driver sleeve and unable to see) for transferring the impact energy of the pile driver 4 to the monopile.

[0023] The system further comprises a sound insulating sleeve 6, for example of steel, which is placed around the foundation member and on the submerged formation to reduce the noise input from the pile driver into the surrounding wa...

Abstract

The invention relates to a method for installing a foundation element, in particular a (single) pile (2), in an underwater ground (3) using a pile driver (4), the method comprising the steps of placing the foundation element (2) in on the submerged formation (3) and hold the base member (2) in place with a gripper (10) mounted on the surface vessel; place around the base member (2) for lowering the load from the pile driver ( 4) the sleeve (6) of the noise input; separate the holder (10); lower the sleeve (6) onto the submerged formation (3); and, place the pile driver (4) on the foundation member (2 ) on top of it. Said sleeve (6) is fixed at least laterally by means of guides (11) installed on the surface vessel, at least when the holder (10) is separated.

Description

technical field [0001] The present invention relates to a method for installing foundation elements, in particular (mono)piles, in underwater formations with a pile driver, eg a hydraulic pile driver. The method includes the steps of placing a base member on a submerged formation and securing the base member in place with a gripper mounted on a surface vessel. An acoustic sleeve for reducing noise input from the pile driver into the surrounding water is placed around the foundation member and lowered onto the subsea formation. The pile driver is then placed on top of the foundation elements and rammed into the foundation elements to the proper depth. Background technique [0002] As explained in European Patent Publication 1 989 358, offshore ramming work is performed underwater to create foundations for eg drilling platforms and wind turbines. For wind turbines, large monopiles, larger than four meters in diameter, are rammed into the seafloor. This ramming results in a ...
