Problems solved by technology
However, after the second docking pier, the horizontal state of the ship may change. If the rudder and propeller device is installed according to the original cable data and positioning reference, the accuracy requirements cannot be guaranteed, and the inspection will not pass.
The accuracy requirements for the second docking pier of the ship are relatively high, which makes it more difficult to install power equipment on the ship and prolongs the installation period

The invention discloses a method for installing a rudder-propeller device for a second-docking ship. After the rudder-propeller device is hoisted into the surrounding shaft, the installation of the connecting flange is corrected according to the height difference H between the reference point D and the central point O and the height change value ΔD position, and fixedly connect the connecting flange with the surrounding well casing after adjustment. The accuracy of the deflection angle of the rudder-propeller device can be ensured by correcting the rudder-propeller device after the second docking pier, thereby greatly reducing the difficulty of installing the rudder-propeller device for ships on the second docking pier.
Description
technical field [0001] The invention relates to the technical field of ship building, in particular to a method for installing a rudder propeller device for a ship in secondary docking. Background technique [0002] The dock is a working platform for repairing and building ships in a shipyard, and a place for repairing and building ships. It is a site facility for repairing and building ships that has been manually processed in the shipyard. The construction and overhaul of ships are usually carried out in the dock. Therefore, the use of the dock must be carried out in strict accordance with the dock construction batches. Any delay in the docking time of any ship will seriously affect the production plan of the entire dock. In the process of building a ship, it often happens that the power equipment cannot arrive at the dock as scheduled, which prolongs the occupancy period of the dock, affects the use of the dock, and makes the production efficiency of the shipyard low. ...
