Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] The terms "first," "second," and so on, in the specification and claims of this utility model and the accompanying drawings are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product, or end comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed therein, or may optionally include other steps or elements inherent to such process, method, product, or end.

[0023] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] This utility model discloses a specific implementation of a new type of fuel supply ship, please see Figures 1 to 2As shown, the fuel supply ship includes a hull 1, within which is located a cargo tank group located in the middle of the hull 1. The cargo tank group comprises a plurality of independent cargo tank bodies 21 arranged in a matrix. A first ballast tank group 31 is provided between the cargo tank group and the outer plating of the hull 1. It should be noted that the cargo tank group adopts a double-bottom double-hull structure, with the double bottom tanks and side tanks forming the first ballast tank group 31. The first ballast tank group 31 comprises a plurality of first ballast tank bodies arranged side by side along the cargo tank group.

[0025] Optionally, the cargo tank group includes ten cargo tank bodies 21 arranged in a rectangular pattern of two rows and five columns. In other embodiments, the number of cargo tank bodies 21 can be six, ten, or twelve, depending on actual needs. In addition to the multiple cargo tank bodies 21, the cargo tank group also includes two slop tanks 22, symmetrically arranged side by side and located at the front end of the cargo tank group. It should be noted that each cargo tank body 21 can be loaded with the same oil product or different oil products, including but not limited to heavy oil, diesel, gasoline, methanol, and biodiesel, depending on operational needs. This improves the suitability of the fuel supply ship and addresses the previous issue of poor suitability. Furthermore, each cargo tank body 21 can be equipped with an inert gas protection system, a fixed tank cleaning system, a liquid level monitoring and alarm system, and an independent closed venting system to ensure the safety and operational stability of each cargo tank body 21.

[0026] In order to save energy and reduce emissions, a methanol fuel tank is provided at the rear end of the cargo tank group, a cargo oil pump compartment 5 is provided at the rear end of the methanol fuel tank, and an engine room is provided at the rear end of the cargo oil pump compartment 5. The engine room is equipped with a main generator set 81 and a mooring generator set 82. The main generator set 81 mainly supplies power to all electrical equipment on the ship, while the mooring generator set 82 can supply power to electrical equipment on board while the ship is moored. The main generator set 81 is equipped with four main generators, and the mooring generator set 82 is equipped with a mooring generator. The four main generators can operate independently or in parallel, and power all electrical equipment on the ship is supplied through a fully automatic intelligent power distribution system. In conjunction with the fully automatic intelligent power distribution system, it can be decided to start one or more main generators according to the real-time power load on the ship, so that each generator set can always operate in a relatively ideal load range, minimizing fuel consumption.

[0027] In addition, the hull 1 is equipped with an intelligent power station, which includes batteries and three solar photovoltaic panels 300 installed on the stern awning of the hull 1. The batteries can power all electrical devices on board. In this embodiment, the batteries can be lithium-ion batteries. Specifically, a set of lithium-ion batteries is provided as the batteries for the energy storage station. The batteries are electrically connected to the main generator set 81 and the mooring generator set 82, respectively, so that the main generator set 81, the mooring generator 82, and the solar photovoltaic panels 300 can charge the batteries. The energy storage station can store excess power from the main generator set 81 and the mooring generator set 82, as well as energy converted by the solar photovoltaic panels 300, to provide daily electricity for the crew while moored, thereby further reducing energy consumption.

[0028] In this embodiment, diesel tanks 51 are located on both the left and right sides of the cargo oil pump room 5. Each diesel tank 51 is connected to the main generator set 81 and the mooring generator set 82 via pipelines. Both the main generator set 81 and the mooring generator set 82 are connected to the methanol fuel tank via pipelines. Using methanol and diesel dual-fuel as the primary fuel for a fuel supply ship significantly reduces energy consumption and emissions, offering flexible equipment configuration and low upgrade and modification costs. The ship is equipped with both diesel and methanol fuel storage tanks. Both the main generator set 81 and the mooring generator set 82 can be powered by either diesel generators or diesel-methanol dual-fuel generators. Given that diesel-methanol dual-fuel generators are not yet widely available, it is feasible to initially deploy diesel generator sets and then upgrade to dual-fuel generator sets once diesel-methanol dual-fuel generator technology matures. Furthermore, the ship's fully automatic intelligent power distribution system allows for quick and easy access to renewable energy sources and grid-connected operation. In the future, when battery technology advances to a certain level, the ship can be upgraded to electrification, achieving the goal of net zero emissions.

[0029] In this embodiment, the cargo pump compartment 5 is equipped with a first cargo pump 61, a second cargo pump 62, a third cargo pump 63, and a fourth cargo pump 64. The first cargo pump 61 and the second cargo pump 62 are connected in parallel, and the third cargo pump 63 and the fourth cargo pump 64 are connected in parallel. The second cargo pump 62 is connected to each cargo tank body 21 via a pipeline, and the fourth cargo pump 64 is connected to each cargo tank body 21 via a pipeline. In addition, the engine compartment is also equipped with a first permanent magnet variable frequency motor 71 for driving the first cargo pump 61, a second permanent magnet variable frequency motor 72 for driving the second cargo pump 62, a third permanent magnet variable frequency motor 73 for driving the third cargo pump 63, and a fourth permanent magnet variable frequency motor 74 for driving the fourth cargo pump 64. The first permanent magnet variable frequency motor 71, the second permanent magnet variable frequency motor 72, the third permanent magnet variable frequency motor 73, and the fourth permanent magnet variable frequency motor 74 are all electrically connected to the main generator set 81.

[0030] Each pair of cargo pumps forms a group, forming two completely independent cargo oil pipeline systems. Each pipeline system consists of two cargo oil pumps and their associated pipelines, valves, and monitoring instruments. By installing the two cargo oil pumps in parallel and acting as backup for each other, they can operate independently or collaboratively to pump oil from any cargo tank to other ships, thereby improving the convenience and reliability of the fuel supply ship's operations. In addition, the failure of a single cargo oil pump will not affect the operation of the other cargo oil pumps. The two cargo oil pipeline systems can carry out replenishment operations simultaneously, significantly improving work efficiency. All cargo oil pumps are driven by permanent magnet variable frequency motors, and starting and stopping can be operated with simple button operations on the cargo control console, which is very convenient and reliable.

[0031] Optionally, a stripping pump is further provided in the cargo oil pump compartment 5, which is connected to each cargo oil tank body 21 through a pipeline. The cargo stripping pump and the corresponding stripping pipeline designed in conjunction can be used to suck a small amount of residual cargo from each cargo oil tank and cargo oil piping system.

[0032] In this embodiment, the rear end of the engine room is equipped with a second ballast tank group 32, which includes at least one second ballast tank body. The forward end of the cargo tank group is equipped with a thruster tank 100, and the forward end of the thruster tank 100 is equipped with a forepeak tank 200. Specifically, the thruster tank is equipped with a thruster device 101, which is electrically connected to the main generator set 81 and is primarily used to assist the ship in berthing and leaving the dock.

[0033] Furthermore, an azimuth propeller 9 is provided on each of the port and starboard sides of the bottom of the engine room. A fifth permanent magnet variable frequency motor 75 and a sixth permanent magnet variable frequency motor 76 are also provided on the port and starboard sides of the bottom of the engine room for driving the azimuth propeller 9. The fifth permanent magnet variable frequency motor 75 and the sixth permanent magnet variable frequency motor 76 are both electrically connected to the main generator set 81. The azimuth propeller 9 is used to control the navigation, steering, and retreat of the ship. Specifically, the number of azimuth propellers 9 can be two or one. When two azimuth propellers 9 are configured on the ship, combined with the coordinated control of the bow thruster, the ship can easily achieve a 360-degree rotation in place.

[0034] The new fuel supply ship of this embodiment has a reasonable overall layout, convenient, fast, safe and reliable operation, and by providing multiple cargo oil tank bodies 21, it can simultaneously load a variety of different fuels, including but not limited to heavy oil, diesel, gasoline, methanol and biodiesel, etc., which solves the problem of poor applicability in the past and has higher applicability.

[0035] Finally, it should be noted that the new fuel supply ship disclosed in the embodiment of the present invention is only a preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to replace some of the technical features therein with equivalents.
