Abstract

The invention discloses a repairing and changing method of a full rotation steering oar device. The repairing and changing method includes: demounting a drive assembly which and the full rotation steering oar device are arranged together; sealing a gap on an input shaft of the full rotation steering oar device; arranging cables on the full rotation steering oar device; demounting the full rotationsteering oar from a ship enclosure well, and hoisting the full rotation steering oar device out of water through the cables; performing repairing and changing on the full rotation steering oar device; sealing the gap on the input shaft of the full rotation steering oar device; hoisting the full rotation steering oar device into water through the cables, and mounting the full rotation ship steering oar device onto the ship closed well; demounting the seal on the input shaft of the full rotation steering oar device; and mounting the drive assembly and the full rotation steering oar together. The repairing and changing method can effectively prevent huge economic loss due to the damaged full rotation steering oar device during ship dockage, can shorten the maintenance period, can reduce themaintenance cost, and can improve the maintainability of the device.

Description

technical field [0001] The invention relates to the technical field of ship propulsion, in particular to a method for repairing a full-turn rudder-propeller device. Background technique [0002] The full-turn rudder propeller is an underwater propulsion device that can provide thrust in a range of 360°, which can make the ship have good maneuverability and dynamic positioning performance, and is widely used in various marine ships and offshore engineering platforms. [0003] When a ship is operating at sea, if the full-turn rudder and propeller device fails, it is usually necessary to dock the ship for maintenance. However, due to the long maintenance cycle of the ship docking, it will cause the ship to be idle for a long time, causing huge economic losses. Especially for offshore platforms such as drilling ships and offshore engineering platforms equipped with multiple sets of full-turn rudder-propeller devices, if one of the full-turn rudder-propeller devices fails, the sh...
