Abstract

The invention relates to the technical field of offshore hoisting, in particular to a bottom ship fixing system and method. The bottom-supported ship fixing system comprises a mounting frame, a fixing pile and a wedge block. Wherein the mounting frame is fixed to the side face of the bottom-supported ship, and a mounting opening extending in the vertical direction is formed in the mounting frame; the fixing pile movably penetrates through the mounting opening to be inserted into a seabed to be fixed, and the top of the fixing pile extends out of an upper deck of the bottom-supported ship; and the wedge block is detachably inserted into a gap between the mounting frame and the fixed pile. When the bottom-supported ship sits on the seabed, the bottom-supported ship fixing system is used, the fixing piles penetrate through the mounting ports from top to bottom and are inserted into the seabed to be fixed, then the wedge blocks are inserted into the gaps between the mounting frames and the fixing piles, and therefore shaking of the bottom-supported ship can be effectively reduced through the fixing piles, and the construction environment required by fan hoisting is met; the defect that in the prior art, a bottom-supported ship is prone to shaking due to the influence of marine environment loads is overcome.

Description

technical field [0001] The invention relates to the technical field of offshore hoisting, in particular to a bottom ship fixing system and a fixing method. Background technique [0002] During the hoisting process of the offshore wind turbine, in order to meet the requirements of the docking accuracy of the hoisted objects such as the nacelle and blades, the crane is not allowed to shake, and a "static-to-static" construction environment is required. For this reason, the following two hoisting designs are often used: one is a jack-up platform with pile legs. During construction, the pile legs are inserted into the seabed, and the hull and crane of the hoisting ship are lifted above the sea surface to avoid waves, etc. The impact of marine environmental loads; the other is a semi-submersible bottom-mounted boat, the hull of the bottom-mounted boat sits directly on the seabed, partially exposed to the sea surface to install cranes, and resists the marine environment through th...
