Embodiment Construction

[0034] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] Please combine Figure 2 to Figure 6 As shown, the installation method of a split jacket foundation on an offshore converter station provided by the present invention divides the jacket foundation into jacket A piece 1 and jacket B piece 2, and prefabricates on jacket B piece 2 Four beef legs4. During offshore construction, install four temporary platforms 3 in the sea area in advance according to the design position at the four corners of the jacket B piece 2, and then use the temporary platform 3 as the measurement base point to install the jacket A piece 1 with a large floating crane , to complete piling, grouting and other work.

[0036] After the installation of jacket A piece 1 is completed, the actual theoretical installation position of jacket B piece 2 is calculated by taking jacket A piece 1 as the measureme...

Abstract

The invention discloses an installation method of a split type jacket foundation on an offshore converter station. The jacket foundation is divided into a jacket piece A and a jacket piece B, whereina plurality of brackets are prefabricated on the jacket piece B, a plurality of temporary platforms are installed in a sea area where the jacket piece B is installed in advance, and the jacket piece Ais installed with the temporary platforms as measurement base points; the theoretical installation position of the jacket piece B is calculated with the jacket piece A as a measurement base point; the jacket piece B is hoisted to the positions of the temporary platforms, the brackets on the jacket piece B are correspondingly placed on the temporary platforms respectively, and the relative positions between the jacket piece A and the jacket piece B are measured with the jacket piece A as a measurement base point; and the brackets are fixed to the temporary platforms corresponding to the brackets respectively, the jacket piece B is installed, after installation is completed, the brackets and the temporary platforms are detached, and the installation work of the jacket foundation is completed. On the premise that the two jacket foundations are independently installed, the relative position precision can meet the design requirement.

Description

technical field [0001] The invention relates to the foundation construction technology of large-scale equipment in offshore wind farms, and more specifically, relates to a method for installing a split jacket foundation on an offshore converter station. Background technique [0002] Offshore converter stations are necessary equipment for the development of offshore wind farms to a certain stage. There have been no actual cases of the construction and installation of large-scale offshore converter stations in China. An offshore converter station is usually divided into an upper main structure and a lower jacket foundation structure. The lower jacket is the basic structure of an offshore converter station and needs to be positioned and installed offshore. Since the weight of the upper main structure of the offshore converter station is close to or exceeds 20,000 tons, and the overall size is relatively large, the method of float-over installation of a large semi-submersible sh...
