Embodiment 1

[0040] Such as Figure 2~6 Among them, a semi-submersible LNG reloading ship, the cross-section of the hull is a frame structure, the middle of the frame structure forms a space for the ship to enter, and a lifting device is provided on the top of the hull. During use, make the hull part of the frame structure be located below the water level line 7, the ship sails into the space of the frame structure, and utilize the lifting device to load and unload the LNG tank container 4. In this way, a stable semi-permanent and stable platform on water can be obtained, which can conveniently supply fuel for LNG fuel ships, and LNG tank container carriers can also easily load and unload LNG tank containers.

[0041] The preferred solution is as Figure 4 , 5Among them, at the bottom of the hull, a plurality of ballast water tanks 109 form the bottom of the frame structure, the top of the ballast water tanks 109 is the buoyancy tank deck 115, and a pump room 110 is also arranged near th...

Embodiment 2

[0052] Such as Figure 1~12 Among them, a marine LNG loading application method adopting the above-mentioned semi-submersible LNG reloading ship, a plurality of semi-submersible LNG reloading ships 1 are arranged along the river, so that the pontoon deck 115 of the semi-submersible LNG reloading ship 1 Below the water level line 7, the ship or container ship that adopts the LNG tank container 4 as fuel enters the frame-shaped structural space of the semi-submersible LNG transshipment ship 1, and utilizes the lift on the top of the semi-submersible LNG transshipment ship 1. Heavy equipment, replacing the LNG tank container 4 for the LNG fuel ship, or loading and unloading the LNG tank container 4 from the container ship. This solution overcomes the difficulties in the approval of shore facilities and the inconvenience of berthing ships on the water, especially the inconvenience of berthing large container ships with deep draft.

[0053] The preferred solution is as Figure 7~...

Abstract

The invention provides a semi-submersible LNG replacement shipment and a marine LNG shipment application method. The cross section of the ship hull is of a frame structure, the middle of the frame structure forms a space for accommodating the ship to sail in, and a lifting device is arranged at the top of the ship hull. A plurality of semi-submersible LNG replacement ships are arranged along the river, so that the floating tank deck of the semi-submersible LNG replacement ship is located below the water level, the LNG tanker or container ship using LNG tanker as fuel enters the frame structurespace of the semi-submersible LNG replacement ship and replaces the LNG tanker for the LNG fuel tanker or loads and unloads the LNG tanker from the container ship by using the lifting device at the top of the semi-submersible LNG replacement ship. By adopting a semi-submersible frame structure, a water-stable semi-permanent operating platform is obtained at a lower cost, which facilitates the replacement of LNG tank containers for ships using LNG tank containers as fuel, or the docking of container ships carrying LNG tank containers for loading and unloading LNG tank containers.

Description

technical field [0001] The invention relates to the application field of LNG energy loading, in particular to a semi-submersible LNG reloading ship and a marine LNG loading application method. Background technique [0002] LNG is the abbreviation of Liquefied Natural Gas (LNG). The main component is methane. It is recognized as the cleanest fossil energy on earth. Colorless, odorless, non-toxic and non-corrosive. There are many ships in my country's inland rivers, and the potential for water transportation is huge. The fuel storage method adopted by the LNG fuel-powered ship in the prior art is a fixed storage tank, because the fixed storage tank depends on the shore filling station or the shore filling pontoon to fill it, for example, it is recorded in the Chinese patent document CN106428445A A kind of mobile tanker, which adopts the fueling method for fuel application. The construction of bunkering stations faces difficulties in site selection, huge investment, and long...
