METHOD FOR FIXED MARINE PLATFORM ASSEMBLAGE AND MOUNTING Russian patent published in 2006 - IPC E02B17/00 

FIELD: marine oil production hydraulic structure building, particularly marine platform assemblage.

SUBSTANCE: method involves forming assembly units, namely support unit, load-bearing deck and block units of upper structure, at subassembly site; docking floating vehicle to subassembly site; serially installing assembling units on stockpile carts; moving assembly units from subassembly site to floating vehicle with the use of above stockpile carts; transporting thereof to assemblage site and performing successive mounting thereof with the use of crane-and-mounting ships. The successive mounting operation involves installing support unit on previously prepared ground; installing piles in corresponding bell-shaped guiders of the support unit; driving the piles and cementing thereof to create pile foundation; arranging load-bearing deck on struts and installation guiding bars having different heights and previously formed on support unit, wherein the load-bearing deck has seats for struts and bars receiving and connection thereof is carried out by successive alignment of above bars and seats.

EFFECT: increased efficiency of building equipment and floating vehicle usage; reduced building time, decreased number of operations to be performed at sea, reduced labor inputs and decreased costs of marine fixed platform building.
