Water adding method in vessel transfer

Abstract

The invention belongs to the technical field of vessels, and discloses a water adding method in vessel transfer. The water adding method comprises the following steps of under the premise that ballast water is not loaded by a vessel bow, transferring a vessel to a semi-submersible ship; moving the semi-submersible ship to a deep pit, and driving the vessel to sequentially submerge for at least two immersion depth until the semi-submersible ship is submerged to be separated from the vessel; when the vessel is submerged to every immersion depth, enabling the ballast water of which the water quantity is corresponding to the immersion depth to be loaded to a ballast tank of the vessel bow by a submersible pump of the semi-submersible ship; and after the semi-submersible ship is submerged to be separated from the vessel, dragging the vessel out of the semi-submersible ship. According to the water adding method disclosed by the invention, when the semi-submersible ship cannot realize the transfer of a vessel filled with the ballast water, in a manner that the vessel of which the ballast water is not loaded is directly transferred to the semi-submersible ship, when the semi-submersible ship drives the vessel to submerge to a certain depth, the buoyance of water is utilized to share the gravity of the vessel, and then the ballast water is loaded in the ballast tank of the vessel bow, until the semi-submersible ship is submerged to be separated from the vessel, so that changing a semi-submersible ship of which the size is small is not needed, and vessel sewerage can be realized.

Description

technical field [0001] The invention relates to the technical field related to ships, in particular to a method for adding water in ship transfer. Background technique [0002] Semi-submersible ships, also known as semi-submersible mother ships, are ultra-long, overweight but inseparable superstructures that are specialized in transporting large offshore oil drilling platforms, large ships, submarines, gantry cranes, and prefabricated bridge components. Special marine vessel for large equipment. [0003] When the semi-submersible barge is working, it will be like a submarine. By adjusting the ballast water volume of the hull, it can smoothly submerge a hull deck the size of a football field into the water at a depth of 10 to 30 meters, and only the ship building is exposed. The loaded cargo (such as yachts, submarines, barges, drilling platforms, etc.) can be towed above the submerged cargo deck. [0004] At present, in the process of flat shipbuilding and launching, in or...
