The invention discloses a 300000-ton floating production and storage wheel bow cargo hold side block remote total set process. The 300000-ton floating production and storage wheel bow cargo hold sideblock remote total set process includes the processes of remote factory total set, land transportation, and marine transportation; the remote factory total set process includes the total set processesof a bow cargo hold larboard block and a bow cargo hold starboard block; the land transportation process adopts two 1000-ton hydraulic flat cars, one flat car is inserted into a first door frame fromthe stern end of the bow cargo hold larboard block to below a fourth door frame and jacks the bow cargo hold larboard block up, and the other one flat car is inserted into the first door frame from the stern end of the bow cargo hold starboard block to below the fourth door frame and jacks the bow cargo hold starboard block up; and the marine transportation process adopts a 5000-ton lighter usedfor transporting the bow cargo hold larboard block and the bow cargo hold starboard block. The 300000-ton floating production and storage wheel bow cargo hold side block remote total set process can effectively alleviate the current situation of shortage of the site resources of a factory platform, the lighter transportation efficiency is improved, and the transportation cost is lowered.
