(57) The invention pertains to fabrication of gravitybased structures (GBS) and can be used as part of development of various kinds of near-shore and offshore production (including natural gas liquefaction, ammonia, methanol, hydrogen production, and power generation), transportation, transshipment, and storage facilities. The GBS production method is as follows: a reinforcement cage is assembled for a rectangular base slab, formwork is installed and the base slab is then concreted. As separate sections of the base slab are concreted, reinforcement cages for inner and outer walls are assembled and concreted by slipforming. As separate wall sections are
