CONSTRUCTION METHOD FOR SPAR PLATFORM CYLINDRICAL DECK AND UPPER FACILITIES, AND SPAR PLATFORM
Document Type and Number:
WIPO Patent Application WO/2019/141242
Kind Code:
A1
Abstract:
A construction method for a spar platform cylindrical deck and upper facilities, and a spar platform. The construction method is as follows: prefabricating upper facilities (2) in modules one by one, after prefabrication of the modules is completed, lifting the modules to a predetermined position of the uppermost deck the a cylindrical body (1), and then connecting the modules to each other and forming a module combination bottom deck at the bottom. Modules in the module combination are modules which have complete structures and can independently be lifted, or are multiple segmented modules formed by segmenting the module combination; during construction of the cylindrical body (1), a skylight opening is reserved on the uppermost deck of the cylindrical body (1) where the upper facilities (2) are mounted, and the module combination bottom deck is able to be placed in the skylight opening; a field closure gap is formed between the skylight opening and the module combination bottom deck; and the field closure gap is filled by means of a field closure connecting structure, so that the module combination bottom deck and the uppermost deck of the cylindrical body (1) together form an integral platform combination deck. The structural design and the construction method of the entire platform are optimized, steel materials are saved, platform construction costs are reduced, construction is facilitated, and the production operations are safe.
