DEVICE AND METHOD OF DRIVING MONOPILE USING SUCTION PILE AT SHALLOW WATER DEPTH

摘要

The present invention relates to a device and a method for driving a monopile using a suction pile at a shallow water depth. The device for driving a monopile using a suction pile at a shallow water depth comprises: a jacket structure having a through hole which a monopile which is a pile to be driven penetrates and which is formed on a deck at an upper end, wherein the jacket structure also has multiple hydraulic linkages for connection with the monopile; and multiple suction piles driven into a seabed ground and having one or more drains/inlets to be connected to a suction pump at the sealed upper end, wherein the jacket structure is fixed by being erect to the multiple suction piles. The jacket structure drives the long monopile into the seabed ground by connection and separation with the monopile to be driven. The device for driving a monopile using a suction pile at a shallow water depth can smoothly install the long monopile at the shallow water depth in case a long pile is exposed above the seawater surface when the long pile is driven into the seabed ground or in case a water depth of a sea where the suction pile to be driven is installed is shallower than the height of the suction pile.;COPYRIGHT KIPO 2016
