Shaft, rudder system mounting process of ten-thousand-ton grade special multipurpose vessel

The invention discloses a mounting process for shaft and rudder systems of a 10,000-ton class special multipurpose vessel, which comprises the following steps: a. before the vessel is launched, a center line of the shaft system and a center line of the rudder system are determined; b. a stern tube is positioned and poured with epoxy, the vessel is launched after a waterproof close board is arranged; and c. a screw shaft, a propeller, a tiller and a rudder blade are arranged. Through adopting the way, the mounting process for shaft and rudder systems of the 10,000-ton class special multipurpose vessel overcomes the inconvenience that the screw shaft, the propeller, the tiller and the rudder blade of the vessel are all placed on a slipway for installation before the vessel is launched in the prior art, and makes the vessel launch after the shaft line and the ruder line are determined and checked, thereby saving time for preparing the screw shaft, the propeller, the tiller and the rudder blade of the vessel, sho
