[0025] Referring to Figures 1 and 2, in some embodiments, a clean fuel container ship may include a hull structure. This hull structure may be capable of navigating in water.

[0026] The hull structure can be used to transport containers as well as other cargo. The hull structure includes: the hull and the main deck 1, which is located on the hull and can be understood as the ship's shell. The upper surface of the main deck 1 is relatively flat, forming a large cargo platform that can be used to load containers. The cargo platform formed by the upper surface of the main deck 1 is usually open.

[0027] In some embodiments, the interior of the hull of the ship is provided with a cargo hold 2. The top opening of the cargo hold 2 forms a hatch, which is formed by the top edge of the sidewall and is located on the main deck 1.

[0028] In some embodiments, a cover 8 is provided at the hatch of the cargo hold 2. The cover 8 can be placed on the top of the cargo hold 2 to prevent debris from entering the cargo hold 2 through the top opening.

[0029] In some embodiments, the cargo hold 2 is located below the main deck 1. An installation space 21 is formed inside the cargo hold 2. The installation space 21 can be used to install a fuel storage tank 3. The fuel storage tank 3 can be used to store LNG and fuel oil. It should be noted that the fuel storage tank 3 can also store other fuels.

[0030] Specifically, the cargo hold 2 has a storage compartment 22 within its installation space 21. The storage compartment 22 forms a storage space 23. A fuel tank 3 is installed within the storage space 23. The inlet 31 of the fuel tank 3 extends out of the storage space 23, allowing fuel to be added to the fuel tank 3 from outside the storage space 23.

[0031] In some embodiments, the accommodating space 23 is provided with an anti-sway device, which is used to connect with the fuel storage tank 3 to prevent the fuel storage tank 3 from shaking and improve the stability of the fuel storage tank 3 installation.

[0032] In some embodiments, the clean fuel container ship also includes an installation platform 4. The installation platform 4 is located within the cargo hold 2. The installation platform 4 may be located above the storage compartment 22 and below the main deck 1.

[0033] In some embodiments, a refueling station 41 is provided on the installation platform 4. The refueling station 41 can be located above the storage compartment 22 and below the main deck 1. This allows the refueling station 41 to not occupy space on the main deck 1, and the refueling station 41 will not protrude from the main deck 1, thus ensuring that container loading on the main deck 1 is not affected, making container loading on the main deck 1 more compact, increasing the container loading capacity on the main deck 1, and without affecting the layout of the walkways on the main deck 1.

[0034] In some embodiments, the distance between the installation platform 4 and the main deck 1 is greater than the height of the refueling station 41. As a result, the refueling station 41 can be fully accommodated on the installation platform 4 without protruding from the main deck 1, thereby allowing the refueling station 41 to not occupy space on the main deck 1, so that container loading on the main deck 1 is not affected, making container loading on the main deck 1 more compact and increasing the container loading capacity on the main deck 1.

[0035] In some embodiments, the top of the fuel storage tank 3 may be provided with a liquid inlet 31, which can extend into the mounting platform 4 and communicate with the refueling station 41. Thus, fuel can be added to the fuel storage tank 3 through the refueling station 41, thereby achieving fuel refueling.

[0036] In some embodiments, the installation platform 4 may also include an electrical equipment room 42, a fuel tank connection station 43, an auxiliary equipment room 44, and a fuel preparation room 45. The refueling station 41, electrical equipment room 42, fuel tank connection station 43, auxiliary equipment room 44, and fuel preparation room 45 are interconnected. The inlet 31 of the fuel storage tank 3 can extend into the fuel tank connection station 43. The electrical equipment room 42 provides power to ensure the normal operation of all equipment. The fuel tank connection station 43 connects the fuel storage tank 3 to external pipelines. The auxiliary equipment room 44 ensures a stable fuel supply. The fuel preparation room 45 performs fuel vaporization and safety pretreatment.

[0037] In some embodiments, the refueling station 41, electrical equipment room 42, auxiliary equipment room 44, fuel tank connection 43 and fuel preparation room 45 can be arranged sequentially along the width of the ship's hull so that fuel enters the fuel storage tank 3 sequentially from the refueling station 41, electrical equipment room 42, auxiliary equipment room 44 and fuel tank connection 43.

[0038] In some embodiments, by placing the refueling station 41, electrical equipment room 42, fuel tank connection 43, auxiliary equipment room 44 and fuel preparation room 45 on the installation platform 4, the pipeline between the refueling station 41 and the fuel storage tank 3 is shortened, thereby reducing pipeline costs.

[0039] In some embodiments, the auxiliary equipment room 44 and the fuel tank connector 43 are connected by an airlock. Specifically, the air pressure and airflow direction between the auxiliary equipment room 44 and the fuel tank connector 43 are controlled by a fan or vacuum pump, thereby preventing direct connection between the auxiliary equipment room 44 and the fuel tank connector 43 and avoiding gas leakage, pollution or dangerous diffusion.

[0040] In some embodiments, a refueling port 5 is provided on the side wall of the cargo hold 2. The refueling port 5 is located on the side wall of the cargo hold 2 along the width direction of the hull. The height of the refueling port 5 is lower than the height of the refueling station 41. The refueling port 5 and the refueling station 41 are connected by a refueling pipe. Thus, fuel can be injected into the fuel storage tank 3 from the refueling port 5 through the refueling station 41.

[0041] In some embodiments, two refueling stations 41 may be provided. The two refueling stations 41 may be respectively located on both sides of the cargo hold 2. The two refueling stations 41 may be located on opposite sides in the width direction of the ship's hull. One refueling station 41, the electrical equipment room 42, the auxiliary equipment room 44, the fuel tank connection 43, the fuel preparation room 45, and the other refueling station 41 may be arranged sequentially in connection along the width direction of the ship's hull.

[0042] In some embodiments, two refueling ports 5 may be provided. The two refueling ports 5 are located on the side walls of the cargo hold 2 along the width direction of the ship's hull. The two refueling ports 5 may be arranged opposite to two refueling stations 41, thereby allowing the user to inject fuel into the fuel storage tank 3 through the two refueling ports 5.

[0043] In some embodiments, the hull is provided with lashing bridges 6, specifically on the main deck 1 of the hull. The lashing bridges 6 are used to secure containers, ensuring that the containers are firmly fixed to the main deck 1 and preventing them from tipping over during the voyage.

[0044] In some embodiments, vent pipes are provided on the refueling station 41, electrical equipment room 42, fuel tank connection 43, auxiliary equipment room 44, and fuel preparation room 45, respectively. Multiple vent pipes are located below the lashing bridge 6, thereby making the hull structure more compact, saving more space and improving the utilization rate of hull space. At the same time, because this location is far from other electrical equipment, the need for these electrical devices to meet explosion-proof requirements can be avoided.

[0045] In some embodiments, a sub-deck walkway 7 is formed between the main deck 1 and the filling port 5, and the sub-deck walkway 7 is located on one side of the filling station 41. The filling port 5 is arranged between the sub-deck walkway 7 and the installation space 21. The sub-deck walkway 7 can communicate with the main deck 1, thereby making the sub-deck walkway 7 more coherently connected to the main deck 1 by ensuring that the filling station 41 does not protrude from the main deck 1.

[0046] In some embodiments, the refueling station 41 and the under-deck walkway 7 are connected by an airlock. Specifically, the air pressure and airflow direction between the refueling station 41 and the under-deck walkway 7 are controlled by a blower or vacuum pump to prevent direct communication between the refueling station 41 and the under-deck walkway 7, thereby avoiding dangerous gas leakage, pollution, or dangerous diffusion.

[0047] In some embodiments, a ballast tank 24 is provided between the inner wall of the cargo hold 2 and the accommodating compartment. The refueling port 5 is located between the under-deck walkway 7 and the ballast tank 24, and the refueling port 5 is separated from the fuel storage tank 3 and the accommodating space 23 by the longitudinal bulkhead of the cargo hold 2.

[0048] In some embodiments, safety detection devices such as a temperature sensor, a liquid collection tray, and a gas leak sensor are respectively installed between the filling port 5 and the filling station 41. The temperature sensor can monitor the liquid temperature inside the filling port 5 or the filling pipeline and the surrounding ambient temperature in real time, thereby ensuring that the system operates within a safe temperature range. The liquid collection tray is used to collect fuel that is accidentally leaked during the filling process, facilitating subsequent recovery or treatment and preventing leaked fuel from flowing into the ground or drainage system. The gas leak sensor is used to detect the concentration of gaseous fuel around the filling port 5, thereby monitoring the concentration level and preventing installation accidents.

[0049] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows:

[0050] This invention provides a clean fuel container ship, which includes a main deck 1, a cargo hold 2, and an installation platform 4. The cargo hold 2 is located below the main deck 1 and contains a storage space 23 for accommodating fuel storage tanks 3. The installation platform 4 is located above the storage space 22 and below the main deck 1. A refueling station 41 is provided on the installation platform 4, and the inlet 31 of the fuel storage tanks 3 extends into the installation platform 4 and communicates with the refueling station 41. Therefore, by arranging the refueling station 41 on the installation platform 4, the refueling station 41 does not occupy space on the main deck 1, and the refueling station 41 does not protrude from the main deck 1, thus ensuring that container loading on the main deck 1 is not affected, making container loading on the main deck 1 more compact, increasing the container capacity on the main deck 1, and without affecting the layout of the walkways on the main deck 1.
