Embodiment 1

[0038] An application method for marine LNG loading, in which a plurality of anchorage-type LNG tank container replacement ships 1 are arranged along a river, and a portal lifting device is provided on the anchorage-type LNG tank container replacement ship 1 for moving from At least one side of the LNG tank container 4 is hoisted onto the ship; preferably, an anchored LNG tank container reloading ship 1 is provided at least every 200 kilometers.

[0039] There are also multiple self-propelled LNG tank container reloading ships 2, and the self-propelled LNG tank container reloading ship 2 is equipped with a sky rail lifting device for hoisting the LNG tank container 4 from at least one end to the A ship using LNG tank containers as fuel containers. like Figure 12 As shown in , the LNG fuel-powered ship does not use fuel in the way of bunkering, but uses the fuel in the way of LNG tank container 4 overall replacement, which greatly improves the efficiency and safety of fuel us...

Embodiment 2

[0050] like Figure 2~4 Among them, a self-propelled LNG tank container reloading ship 2 used in the above-mentioned marine LNG application method, a sky rail 21 along the length direction of the hull is fixed on the hull, and one end of the sky rail 21 is provided with a sky rail end The head extension 22, the horizontal plane projection of the sky rail end extension 22 extends beyond the end of the hull;

[0051] The sky rail 21 is provided with a longitudinal traveling cart 23 walking along the sky rail 21, the longitudinal traveling cart 23 is provided with a transverse traveling trolley 24, and the transverse traveling trolley 24 is provided with a hoisting device.

[0052] In the preferred scheme, a plurality of LNG tank container compartments 5 are arranged at the stern of the ship, and the LNG tank container 4 is arranged in the LNG tank container compartment 5, and the LNG tank container 4 passes through the pipeline system and the internal combustion engine of the po...

Abstract

A marine LNG shipment application method and self-propelled LNG tank container replacement ship are provided. A plurality of anchorage LNG tank container replacement ships are arranged along rivers, and a gantry lifting device is arranged on that anchorage LNG tank container replacement ships for hoisting the LNG tank container onto the ship from at least one side. A plurality of self-propelled LNG tank container changers are also provided, and a self-propelled LNG tank container changer cabin is provided with a sky-orbiting lifting device for lifting the LNG tank container from an anchorage LNG tank container changer to a ship using the LNG tank container as a fuel container. The present invention can solve the fuel supply problem of an LNG ship at a lower cost. The LNG fuel supply is conveniently realized by replacing LNG tank containers. According to the total mileage of the Yangtze River trunk line from Shanghai to Shanghai is 2583 km, only 13 anchorage type LNG tank containers areneeded to replace the loading vessels in this section of the Yangtze River trunk line to solve the problem of LNG filling on the Yangtze River trunk line.

Description

technical field [0001] The invention relates to the application field of LNG energy shipment, in particular to an application method for marine LNG shipment and a self-propelled LNG tank container replacement ship. 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, hug...
