Embodiment Construction

[0027] 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 bed, is shown. In this example, the monopile 2 has a circular cross-section and a diameter of five meters, and is intended to be used as a foundation for a wind turbine after installation.

[0028] System 1 includes: hydraulic pile driver 4 ( figure 2 shown in ), such as an IHC hydraulic hammer S-1800, which is connected to a power unit on a surface vessel such as a ship or a jack-up barge (not shown); mounted on the monopile; and an anvil (hidden from view by the pile driver shield) for transferring the impact energy of the pile driver 4 to the monopile.

[0029] The system also includes a noise reduction shield 6, eg made of steel, placed around the foundation member to reduce the input of noise from the pile driver into the surrounding water. In this example, the shield comprises an inner wall and an outer wall, ie the shield i...

Abstract

The invention relates to a method and a noise abatement system (1) for installing foundation elements, in particular (mono)piles (2), comprising a shield (6), in which foundation elements, in particular (mono)piles ( 2) During ramming into the submerged formation (3), a shield is placed around the base member (2) to reduce the noise input into the surrounding water, such as a river or ocean, caused by ramming. The method and system (1) comprise a further shield (7, 9) arranged around the (first) shield (6).

Description

technical field [0001] The invention relates to a method for installing a foundation element, in particular a (single) pile, in an underwater formation by means of a pile driver, comprising the steps of placing the foundation element on the underwater formation, for example directly on the bed of a river or sea Either on a scour or rock formation; placing a shield to reduce noise input from the pile driver into the surrounding water; and ramming the foundation member into the formation by the pile driver while positioning the shield around the foundation member. The invention also relates to a noise abatement system comprising a shield placed around a base member. Background technique [0002] As described in WO 2007 / 096132, offshore ramming operations are carried out under water to create foundations eg for drilling platforms and wind turbines. For wind turbines, large monopiles, over four meters in diameter, are rammed into the seabed. This ramming results in a considera...
