The invention pertains to construction of production facilities and can be used as a part of construction of production complexes intended for hydrocarbon processing, storage, and offloading of the processed products (including, but not limited to, natural gas liquefaction plants, ammonia plants, hydrogen plants, as well as power plants) on gravity-based structures (GBS). Topside modules are fabricated at a production site. A gravity-based structure (GBS), which can stay afloat during transportation by water, is used as a foundation for the modules installation. Modules fabrication includes the following stages: At Stage I, components are fabricated; at Stage II, nodes are fabricated from the components; at Stage III, sub-assemblies are fabricated from the nodes; at Stage IV, assemblies are shotblasted and painted; and at Stage V, modules are assembled from the assemblies. Then modules transportation, movement to their seats on the GBS and their integration include the following Stages. At Stage VI, the modules are moved to an area near the dock with the help of self-propelled vehicles. At Stage VII, each module is moved onto guides of a lifting system installed in a dry dock. At Stage VIII, each module is lifted until lifting system guides are connected with guides of the GBS top slab. At Stage IX, each module is moved to its seat on the GBS, installed on the GBS and integrated with other modules and the GBS. The invention allows establishing a GBS production complex which can withstand ice impact in ice conditions, fully fabricate the production complex at a specialized production site with dry dock(s), provides better maneuverability during movement of individual topside modules at the fabrication yard and eliminate the need for special bridge structures to move topside modules on the GBS.
