Description

Technical Field

[0001] The present application relates to the technical field of polar ship construction, and in particular to a polar ship engine room layout method and a ship. Background Art

[0002] The polar region has important scientific research value and rich resources. In addition, polar routes shorten the distance by 40% compared with traditional Asia-Europe and Asia-America routes, greatly shortening the distance and saving transportation costs. The polar regions have become a strategic space that countries around the world must compete for in the future development. The development of the polar regions has gradually become an important project for world development. Therefore, the development of ships suitable for polar navigation (referred to as "polar ships") is of great significance.

[0003] Compared to ordinary ships, polar ships require special systems, equipment, and structural designs to cope with the polar navigation environment due to the unique sea ice and low temperature environment in the polar region. Therefore, polar ships are equipped with more equipment and more complex systems. The engine room area is also the concentrated area of ship equipment. In polar ship design, due to the smaller size of polar ships, the equipment and systems inside the engine room are more numerous and complex. If the cabins and equipment in the engine room are arranged according to the conventional method of first designing the hull structure and then arranging the equipment on the hull structure, the equipment will often be arranged in a complex manner, resulting in a scattered layout of the engine room piping and low space utilization in the engine room. It is difficult to arrange the equipment in the engine room of polar ships in a reasonable manner, and it is impossible to meet the layout requirements of polar ships. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0041] The engine room is the central area of a ship's equipment. Conventional ship engine room layouts typically determine the hull structure first, then arrange the equipment and compartments based on this structure. However, polar vessels are relatively small, and to cope with the unique polar navigation environment, their engine rooms contain more equipment and complex systems. Conventional engine room layouts are no longer sufficient to meet the equipment and system requirements of polar vessels. Furthermore, polar vessels differ from traditional ships in that their hulls are exceptionally strong.

[0042] Based on the above situation, in order to achieve a more reasonable equipment layout, more efficient space utilization, and more intensive piping layout in the engine room, while also meeting the equipment and system requirements of polar ships, the inventors, taking into account the characteristics of polar ships, have proposed an engine room layout method and a polar ship suitable for polar ships. The invention is elaborated and described in detail below.

[0043] In the first aspect, the present application provides a method for arranging a polar ship engine room, see Figure 1-Figure 7 , including the following steps:

[0044] The cabin area is designed based on the input of the main dimensions, line shape and spatial scope of the cabin. That is, the design input required for cabin layout is first clarified, including the overall design, such as the main dimensions, line shape, cabin spatial scope, etc. Based on the design input, the required area of the cabin is designed.

[0045] Obtain the specifications and layout requirements for the equipment and compartments to be arranged in the engine room area. The equipment includes the main engine 210, auxiliary engine 320, fuel boiler 220, exhaust gas boiler 230, cooling unit, main air compressor, central cooler, and main engine remote control panel. The compartments include the central control room 310, electrician's storage room 330, starter box room 340, and multiple oil tanks. The multiple oil tanks include the main engine cylinder oil storage tank 110, fuel oil service tank 120, fuel oil settling tank 130, lubricating oil storage tank 140, lubricating oil settling tank 150, diesel service tank 160, fuel oil storage tank 170, and domestic sewage tank 180. Layout requirements include shipowner requirements, regulatory requirements, and construction requirements.

[0046] According to the specifications and layout requirements of the equipment and compartments, the engine room area is divided into the oil tank area 100, the main engine area 200, and the engine room control area 300 in the bow and stern direction of the hull. The main engine cylinder oil storage tank 110, the fuel daily tank 120, the fuel settling tank 130, the lubricating oil storage tank 140, the lubricating oil settling tank 150, the diesel daily tank 160, the fuel storage tank 170, and the domestic sewage tank 180 are centrally arranged in the oil tank area 100. The main engine 210, the fuel boiler 220, the exhaust gas boiler 230, the cooling unit, the main air compressor, the central cooler, and the main engine remote control panel are centrally arranged in the main engine area 200. The control room 310, the auxiliary engine 320, the electrician's storage room 330, and the starting box room 340 are centrally arranged in the engine room control area 300.

[0047] After the equipment and cabins are arranged in the engine room area, the hull structure is separately designed for the oil tank area 100, the main engine area 200, and the engine room control area 300. The hull structure includes a hull platform and longitudinals. The designed hull structure is then arranged in the oil tank area 100, the main engine area 200, and the engine room control area 300. The various areas are connected by stepped connections so that the hull structure in each area, and the relationship between the hull structure and the equipment and / or cabins, all meet the preset construction standards. The hull structure design includes arranging the hull platform, arranging the longitudinals, and determining the specifications such as material and plate thickness. The structural design should meet the requirements of the specifications. The hull platform includes the inner bottom 10, the floor 20, the second platform 30, the first platform 40, the upper deck 50, the poop deck 60, and the helicopter platform deck 70.

[0048] During the above implementation process, according to the characteristics of each cabin and equipment, and due to the high strength of the hull shell of polar ships, this application breaks the conventional idea of engine room layout and attempts to first select a suitable location in the engine room to arrange the equipment and cabins. After the equipment and cabins are arranged, the hull structure design is carried out, so that the equipment layout in the engine room of the polar ship is more reasonable, the space utilization is more sufficient, and the pipeline layout is more intensive, while at the same time being able to meet the equipment and system requirements of polar ships.

[0049] In one embodiment, in order to effectively reduce the layout of the pipelines, reduce the layout of the isolation cabin 400, and improve the utilization efficiency of the space in the cabin, see Figure 2 , the main engine cylinder oil storage tank, fuel daily tank, fuel sedimentation tank, lubricating oil storage tank, lubricating oil sedimentation tank, diesel daily tank and fuel storage tank are centrally arranged in the oil tank area including:

[0050] According to the specifications and layout requirements of oil tanks and cofferdams, the oil tank area is staggered to divide into multiple layout spaces that are adapted to the volume of the oil tanks, including spaces with irregular shapes;

[0051] The main engine cylinder oil storage tank 110, the fuel daily tank 120, the fuel sedimentation tank 130, the lubricating oil storage tank 140, the lubricating oil sedimentation tank 150, the diesel daily tank 160 and the fuel storage tank 170 are arranged one by one in the appropriate layout space.

[0052] Specifically, the layout of the oil tank area in the engine room area includes: along the up and down directions of the hull, in accordance with the arrangement order of the main engine cylinder oil storage tank 110, the diesel daily tank 160, the fuel daily tank 120, the fuel sedimentation tank 130 and the fuel storage tank 170, a plurality of adaptive layout spaces are divided in the oil tank area from top to bottom; two layout spaces adapted to the lubricating oil storage tank 140 and the lubricating oil sedimentation tank 150 are divided in the area close to the fuel sedimentation tank 130; the two layout spaces adapted to the fuel daily tank 120 and the fuel sedimentation tank 130 are both set to be L-shaped, and the layout space adapted to the diesel daily tank 160 is divided within the area enclosed by the L-shaped fuel daily tank 120.

[0053] In the above implementation process, the oil tanks are centrally arranged by finding a suitable location in the engine room that meets the total tank capacity of multiple oil tanks, then dividing the space of each oil tank according to the tank capacity requirements and regulatory requirements, and finally carrying out structural design and verification. This achieves full utilization of the engine room area and reduces the layout of isolated empty tanks and pipelines.

[0054] In one embodiment, centrally arranging the host machine 210, the fuel oil boiler 220, the exhaust gas boiler 230, the cooling unit, the main air compressor, the central cooler, and the host machine remote control panel in the host machine area 200 includes:

[0055] The main engine 210 is placed on the lower level, with the oil-fired boiler 220, exhaust gas boiler 230, cooling unit, main air compressor, central cooler, and main engine remote control panel arranged around it. The oil-fired boiler 220 and exhaust gas boiler 230 are placed on the upper level, with the exhaust gas boiler 230 located on the upper level, close to the exhaust port of the main engine 210. By arranging the boilers on the upper level and the exhaust gas boiler on the upper level, close to the exhaust port of the main engine within the designed engine room area, platforms can be set up according to the height of the boilers during hull structural design and verification. This significantly reduces piping distance and space occupation, improves air circulation efficiency, and enhances space utilization within the engine room.

[0056] In one embodiment, centrally arranging the control room 310, auxiliary engine 320, electrician storage room 330, and starter box room 340 in the cabin control area 300 includes:

[0057] The control room 310 and auxiliary generators 320 are arranged on two levels within the engine room control area 300. The electrical storage room 330 and starter box room 340 are then located around the auxiliary generators 320. By first arranging the control room 310 and auxiliary generators 320 within the engine room and surrounding them with the associated compartments, the structural design is then performed. Separate two-level platforms are then provided for the control room and generators, and finally, the structural verification is performed. This results in a more rational and centralized layout of equipment and compartments, while also reducing the length of piping and circuits.

[0058] Specifically, see Figure 2-Figure 7 The designed hull structure is arranged in the oil tank area 100, the main engine area 200 and the engine room control area 300, including:

[0059] See also Figure 2-Figure 3 The designed hull structure is arranged in the oil tank area 100, including arranging a floor 20 between the fuel oil settling tank 130 and the fuel oil storage tank 170, and the floor 20 is located at the bottom of the lubricating oil storage tank 140, arranging a second platform 30 between the fuel oil daily tank 120 and the fuel oil settling tank 130, arranging a first platform 40 between the fuel oil daily tank 120 and the diesel daily tank 160, and arranging longitudinal bones between multiple arrangement spaces.

[0060] See also Figure 4-Figure 5 The designed hull structure is arranged within the main engine area 200, including the inner bottom 10, second platform 30, first platform 40, and upper deck 50 arranged around the main engine 210, and the helicopter platform deck 70 arranged above the main engine 210. The inner bottom 10, second platform 30, first platform 40, and upper deck 50 are all fixed to the hull shell at one end and suspended near the main engine 210 at the other end. The oil boiler 220 is arranged on the first platform 40, and the exhaust gas boiler 230 is arranged above the helicopter platform deck 70.

[0061] See also Figure 6-Figure 7 The designed hull structure is arranged in the engine room control area 300, including arranging an upper deck 50 between the control room 310 and the auxiliary engine 320, arranging a first platform 40 around the auxiliary engine 320, one end of the first platform 40 is fixed on the hull shell, and the other end is suspended in the hull, the pipeline of the auxiliary engine 320 extends upward from the upper deck 50, and arranging a second platform 30 at the bottom of the auxiliary engine 320 and the electrician storage room 330; longitudinal bones are arranged at the periphery of the auxiliary engine 320, the electrician storage room 330 and the starting box room 340.

[0062] During the above implementation process, the hull structure is designed and arranged for each area (oil tank area, main engine area and engine room control area) according to the structural characteristics and layout requirements of different areas. The hull platforms in each area may not be on the same horizontal plane, and can be designed separately according to the equipment and cabins in each area. In this way, while meeting the equipment and system requirements of polar ships, the equipment layout in the engine room can be more reasonable, the space utilization can be more sufficient, and the pipeline layout can be more intensive.

[0063] In one embodiment, ensuring that the hull structure in each area, and the relationship between the hull structure and equipment and / or cabins meet the preset construction standards includes:

[0064] The overall structure of the engine room is checked. If the check result does not meet the preset construction standards, the layout of the equipment and cabins is adjusted, including strengthening the openings of the equipment's air ducts and stairways between areas, or interactively coordinating the equipment, cabins and hull structures until the preset construction standards are met. Specifically, there is an interactive coordination process between the cabin structure design check process and the equipment and cabin layout process. If the structural check is difficult to meet the requirements, the layout of the equipment cabin can be adjusted, and the opening positions of the air ducts, stairways, etc. and the equipment positions can be strengthened. If it is difficult to meet the structural check requirements or construction requirements, coordination and adjustments can also be made, and ultimately a design state that meets all requirements should be achieved. The overall structure of the engine room is checked using standard calculations, finite element strength calculations, vibration calculations and fatigue calculations to meet relevant requirements such as finite element strength calculation requirements, vibration calculation requirements, and fatigue calculation requirements.

[0065] In a second aspect, the present application further provides a ship, comprising an engine room, which is arranged according to the polar ship engine room arrangement method as described in any one of the implementation schemes in the first aspect.

[0066] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
