Description

Technical Field

[0001] This application relates to the technical field of medium and large bulk carrier design, and particularly to a general arrangement of a bow-island type dual-fuel bulk carrier. Background Art

[0002] Most of the medium and large bulk carriers currently under design, construction and operation adopt an arrangement where the main engine room is located at the stern of the ship and the superstructure is also located at the stern of the ship. This design is also known as a tail-engine and tail-island type bulk carrier. With the increasingly strict requirements of the International Maritime Organization (IMO) for ship decarbonization, the application of alternative fuels (such as LNG, ammonia, methanol, etc., where LNG refers to liquefied natural gas, and its full name is Liquefied Natural Gas) in bulk carriers is gradually increasing. In the design of conventional dual-fuel bulk carriers, fuel storage tanks are usually arranged on the deck above the engine room, on both sides or at the rear of the superstructure.

[0003] In the above arrangement, the fuel storage tanks are close to the cabins where the crew lives. Although the arrangement of the fuel storage tanks has undergone a series of safety analyses and corresponding safeguard measures have been taken, fuels such as LNG, ammonia, and methanol still pose risks such as leakage and deflagration. This not only reduces the safety of the crew's living environment but also has an adverse impact on its comfort. In addition, many current dual-fuel bulk carriers are equipped with energy-saving devices such as wind turbine rotors. Due to the height and angle problems of these energy-saving devices, the visibility of the tail-island type bulk carrier is restricted to a certain extent. However, no perfect solution to these problems has been found yet. Summary of the Invention

[0004] In view of this, the main purpose of this application is to provide a general arrangement of a bow-island type dual-fuel bulk carrier, which is beneficial to solving the problems of crew safety threats and restricted driving visibility existing in the current tail-island type bulk carriers.

[0005] This application provides a general arrangement of a bow-island type dual-fuel bulk carrier, which includes:

[0006] A superstructure, which is configured at the bow of the ship;

[0007] A cargo hold area passage, which runs through the cargo hold area and is arranged on both sides of the cargo hold opening along the length direction of the ship to connect the superstructure, the cargo hold area and the aft working area;

[0008] A drainage device, which is arranged inside the cargo hold area passage;

[0009] An outfitting platform, which is arranged on the deck between two adjacent cargo hold openings, and the height of the outfitting platform is the same as the height of the top of the hatch coaming of the cargo hold opening;

[0010] The forecastle deck is arranged in the form of being high in the middle and low on both sides between the front wall of the superstructure and the outer plate of the ship's bow;

[0011] Two fuel storage tanks are symmetrically distributed at the ship's tail configuration;

[0012] The stern working area is arranged at the middle position on the side where the two fuel storage tanks face the ship's bow.

[0013] As above, the living quarters of the crew, that is, the superstructure, are arranged at the ship's bow, and the two fuel storage tanks are still on the upper deck of the engine room working area at the ship's tail, thus solving the problems of the field of vision of the ship's cab, the potential safety hazards and comfort caused by being too close to the fuel storage tanks. And two deck passages, namely the cargo hold area passages, are arranged between the superstructure at the ship's bow and the stern working area, located on both sides of the cargo hold opening, to solve the problems of passage and escape at the ship's bow and stern in bad weather. A drainage device is arranged inside the cargo hold area passages, which can effectively drain accumulated water and reduce the risk of goods being damaged by moisture. The deck between the cargo hold openings adopts a double deck, and an outfitting platform is arranged on the deck between adjacent two cargo hold openings and its height is equal to the top of the hatch coaming of the cargo hold opening, which is conducive to the smooth progress of cargo handling operations, improves work efficiency, and also makes reasonable use of the ship's space. The hatch coaming and the cargo hold area passages form a longitudinally continuous structure of the hull girder, increasing the longitudinal strength of the entire hull girder; A forecastle deck is arranged between the height above the first floor of the front wall of the superstructure at the bow and the outer plate of the ship's bow as a wave baffle. The forecastle deck adopts the form of being high in the middle and low on both sides to prevent water accumulation, so as to ensure the safety of outdoor personnel in the superstructure at the bow. This general arrangement solves the potential safety hazards brought by the proximity of the superstructure and the fuel storage tanks, separates the living quarters and the working area of the crew, greatly improves the safety and comfort of the crew's living environment, and completely solves the problem of limited field of vision of the ship's cab.

[0014] Optionally, the height of the side of the forecastle deck facing the superstructure is greater than or equal to the height of the first floor of the superstructure.

[0015] As above, the side of the forecastle deck facing the superstructure adopts a heightened design, and the forecastle deck can better prevent seawater from surging onto the deck from the front and entering the superstructure, and can more effectively resist the impact of waves and protect the superstructure from direct damage.

[0016] Optionally, the height of the cargo hold area passage is 2000mm and the width of the cargo hold area passage is 800mm.

[0017] As above, designing the dimensions of the cargo hold area passage that meet safety standards can not only facilitate the daily inspection and maintenance work of the crew, but also improve the safety of the crew's work.

[0018] Optionally, nine cargo hatches are arranged side by side along the length direction of the ship's hull, and the cargo hatch cover above the sixth cargo hatch in the order from the bow to the stern is set as the landing platform.

[0019] As above, setting the landing platform for the flight device on the cargo hatch cover at a specific position improves the flexibility and convenience of the operation.

[0020] Optionally, two outfitting platforms are respectively arranged in the deck areas at the gaps between the second, third, and fourth cargo hatches in the order from the bow to the stern.

[0021] As above, arranging the outfitting platforms in the deck areas between specific cargo hatches not only increases the flexibility of using the deck area but also provides a safer operating environment for the staff.

[0022] Optionally, another two outfitting platforms are respectively arranged in the deck areas at the gaps between the seventh, eighth, and ninth cargo hatches in the order from the bow to the stern.

[0023] As above, the outfitting platforms can also provide a temporary storage area for the equipment.

[0024] Optionally, wind-assisted rotors are alternately assembled on the left and right sides of the plurality of outfitting platforms.

[0025] As above, when the wind-assisted rotors are not in use, they can be laid down on the outfitting platforms, and at this time, the outfitting platforms can be used as a temporary storage area for the wind-assisted rotors.

[0026] Optionally, the wind-assisted rotors are assembled at the port side positions of the first and third outfitting platforms in the order from the bow to the stern; the wind-assisted rotors are assembled at the starboard side positions of the second and fourth outfitting platforms in the order from the bow to the stern.

[0027] As above, assembling the wind-assisted rotors alternately at the port and starboard side positions of the outfitting platforms can not only maintain the lateral balance of the ship but also enable the ship to make more effective use of wind resources under different sailing conditions.

[0028] Optionally, a building is provided in the stern working area for the working areas of the fuel preparation room, toilet, and garbage station.

[0029] As above, concentrating functional areas such as the fuel preparation room, toilet, and garbage station in a building on the stern of the ship helps to achieve centralized management of resources and services, and also improves the working environment and enhances the functionality and adaptability of the ship.

[0030] Optionally, support saddles are provided at the bottom ends of the two fuel storage tanks, and the support saddles are arranged on the deck; a chimney is arranged at the middle position between the two fuel storage tanks for discharging the exhaust gas of the main engine room.

[0031] As described above, the support saddles provide stable support for the fuel storage tanks and protect the fuel storage tanks themselves from damage; a chimney is arranged at the middle position between the two fuel storage tanks, and the chimney is connected to the main engine room, effectively utilizing the hull space and simplifying the connection and maintenance work of the exhaust gas discharge system.

[0041] Explanation of Ship Terminology

[0042] Superstructure refers to an enclosed building on the upper deck of a ship that extends from one side to the other or whose sidewalls are recessed from the outer plate by no more than 4% of the ship's width, namely the forecastle, bridge and poop. If not strictly distinguished, various enclosed buildings above the upper deck can be collectively referred to as the superstructure, and sometimes it also generally refers to the deck buildings including the deckhouse. The superstructure can be used to arrange various cabins, battle positions and various devices, etc. For example, the bridge is set at the top of the superstructure in the middle or at the aft of the ship, which is conducive to expanding the field of vision of the crew; passenger cabins and crew's living cabins can be set in the superstructure, and the forecastle can also reduce the waves hitting the deck.

[0043] Fore island refers to an island-type superstructure at the front of a ship, which is usually used to install radar, communication equipment and other navigation equipment.

[0044] Bow refers to the front end or the front part of a ship, which itself means "ship's head" or "the bow of the ship".

[0045] The stern refers to the rear end or the tail part of a ship, which itself means "the stern of the ship" or "the tail part of the ship".

[0046] The aft-engine and aft-island type bulk carrier is a specific type of ship design. Its main characteristics are that the main engine and the engine room are located at the stern, and the superstructure (usually called the "aft island") is also close to the stern.

[0077] Optionally, wind-assisted rotors 7 are alternately assembled on the left and right sides of multiple outfitting platforms 4.

[0078] Specifically, when the wind-assisted rotors 7 are not in use, the wind-assisted rotors 7 can be laid down on the outfitting platform 4, and the outfitting platform 4 can be used as a temporary storage site for the wind-assisted rotors 7 at this time.

[0079] Optionally, wind-assisted rotors 7 are assembled at the port side positions of the first and third outfitting platforms in the order from the bow to the stern of the ship; wind-assisted rotors 7 are assembled at the starboard side positions of the second and fourth outfitting platforms in the order from the bow to the stern of the ship.

[0080] Specifically, the wind-assisted rotors 7 are alternately assembled at the port side and starboard side positions of the outfitting platform 4, which can not only maintain the lateral balance of the ship but also enable the ship to make more effective use of wind resources under different sailing conditions.

[0081] In a specific embodiment of the present application, on the upper deck at the bow of the ship, a superstructure 1 is provided. The superstructure 1 is designed with a total of six floors. The ship's cab is located at the top floor of the superstructure 1. The view of the ship's cab is wide and there will be no problem of limited vision. Exit channels are respectively arranged on both sides at the end of the superstructure 1 facing the stern. A forecastle cover 5 is arranged between the height above the first floor of the front wall of the superstructure 1 and the outer plate of the ship's bow. The forecastle cover 5 serves as a wave baffle to prevent the deck from being flooded by waves. The forecastle cover 5 adopts a form with a higher middle and lower sides to prevent water accumulation, so as to ensure the safety of outdoor personnel in the area of the superstructure 1. An anchor and an anchor chain connected to the anchor are arranged on the outer plate at the lower front side of the forecastle cover 5, and they are symmetrically arranged on both sides of the bow.

[0082] The middle part of the ship is the cargo hold area, with 9 cargo hatches arranged in sequence from the bow to the stern, and the cargo hatches are named as the first cargo hatch, the second cargo hatch, the third cargo hatch, the fourth cargo hatch, the fifth cargo hatch, the sixth cargo hatch, the seventh cargo hatch, the eighth cargo hatch and the ninth cargo hatch in sequence from the bow to the stern; cargo hatch cover guide rails are arranged on both sides of each cargo hatch, and the length of the cargo hatch cover guide rails extends along the width direction of the hull. When the cargo hatch cover is opened, it can be opened to both sides in the width direction of the hull according to the cargo hatch cover guide rails; an outfitting platform 4 is arranged on the deck area between the second cargo hatch and the third cargo hatch, which can be called the first outfitting platform, and a wind-assisted thruster rotor 7 is arranged at the port side of the first outfitting platform, and the wind-assisted thruster rotor 7 includes a rotor outer cylinder at its upper end and a rotor base at its lower end, and the wind-assisted thruster rotor 7 falls on the first outfitting platform when it is laid down.
