Description

Technical Field

[0001] The invention belongs to the technical field of ship equipment installation, and in particular relates to a method for equipment to enter a gas equipment room. Background Art

[0002] In the prior art, there are a large number of equipment in the gas equipment room of a 110,000-ton dual-fuel crude oil / finished oil tanker. Due to the large size of the equipment, it is usually required to be hoisted in the dock stage. If hoisting in the air is not possible, a temporary process hole is usually opened to hoist the equipment into the cabin.

[0003] Since there are many equipments and different equipment suppliers, and aerial lifting is required, it is easy for the late arrival of equipment to affect the upper-level section lifting node, thereby affecting the ship's undocking node.

[0004] When the equipment cannot be hoisted in the air, a temporary process hole needs to be opened to enter the cabin. Since the equipment is large, many profiles need to be disconnected when opening the temporary process hole, which can easily cause the wall panel to deform. At the same time, the workload of opening and sealing the temporary process hole is huge. At the same time, it is difficult to enter the equipment through the temporary process hole because the size of the temporary process hole needs to be controlled. Summary of the invention

[0005] The present invention provides a method for entering a gas equipment room into a gas equipment room, comprising the following steps:

[0006] S1: Select the crane ship specifications based on the weight of the second-layer section, the weight of the equipment and the height of the ship;

[0007] S2: crane vessel auxiliary hook lifting equipment;

[0008] S3: The crane's main hook lifts the second-layer section;

[0009] S4: Lift the equipment to the equipment installation position on the first-floor main section;

[0010] S5: Lift the second-layer segment onto the first-layer segment;

[0011] S6: Weld the second layer section and the first layer section.

[0012] Further: In S1, the crane vessel is fixed to one side of the ship, and the crane vessel is a floating crane vessel.

[0013] Further: In S1, the floating crane is fixed by four anchors at four corners.

[0014] Further: In S2, the elevation angle of the steel frame of the crane vessel is adjusted.

[0015] Further: In S3, the main hook of the crane vessel lifts the second-layer section and lifts it vertically to a safe distance from the deck of the ship.

[0016] Further: In S3, the lower corner of the second-layer total section is made higher than the top of the LNG tank.

[0017] Further: in S4, the equipment is installed after being hoisted to the equipment installation position on the first-floor main section.

[0018] Further: in said S5, the second-layer total section is hoisted to the top of the first-layer total section, and the main hook is vertically moved until the second-layer total section is hoisted onto the first-layer total section.

[0019] Further: In S5, a plurality of code plates are welded and fixed.

[0020] Further: In S5, a single side surface in the transverse direction of the connection between the second layer section and the first layer section is welded and fixed by at least two code plates, and a single side surface in the longitudinal direction of the connection between the second layer section and the first layer section is welded and fixed by at least two code plates.

[0021] The beneficial effects brought by the present invention are as follows:

[0022] It can be seen from the above scheme that the present invention provides a method for equipment entry into a gas equipment room. Through the method for equipment entry into a gas equipment room, the node impact caused by the equipment delivery time problem is reduced, and the strength impact and workload caused by opening a temporary process hole are reduced.

[0033] like Figures 1 to 8 As shown, the present invention provides a method for entering a gas equipment room into a cabin, and the method for entering a gas equipment room into a cabin comprises the following steps:

[0034] S1: Select the specifications of the crane vessel 5 according to the weight of the second-layer section 1, the weight of the equipment 9 and the height of the vessel 4;

[0035] S2: crane vessel 5 auxiliary hook 7 hoists equipment 9;

[0038] S5: hoist the second-layer segment 1 onto the first-layer segment 2;

[0039] S6: Welding the second layer segment 1 and the first layer segment 2.

[0040] It can be seen from the above scheme that the embodiment of the present invention provides a method for equipment entry into a gas equipment room. Through the method for equipment entry into a gas equipment room, the node impact caused by the time of equipment 9 arrival is reduced, and the strength impact and workload caused by opening a temporary process hole are reduced.

[0041] Furthermore, in S1, the crane vessel 5 is fixed to one side of the ship 4, and the crane vessel 5 is a floating crane vessel.

[0042] like Figure 6 As shown, the floating crane is fixed by four anchors 6 at four corners.

[0043] Further: in said S2, the elevation angle of the steel frame of the crane vessel 5 is adjusted.

[0044] Further: In S3, the main hook 8 of the crane vessel 5 lifts the second-layer segment 1 and lifts it vertically to a safe distance from the deck surface of the ship 4.

[0045] Further: In S3, the lower corner of the second-layer total section 1 is made higher than the top of the LNG tank.

[0046] Further: in S4, the equipment 9 is installed after being hoisted to the equipment 9 installation position on the first-layer main section 2.

[0047] Further: in S5, the second-layer total section 1 is hoisted to the top of the first-layer total section 2, and the vertical main hook 8 is raised until the second-layer total section 1 is hoisted onto the first-layer total section 2.

[0048] Further: In S5, a plurality of code plates 3 are welded and fixed.

[0049] Further: in S5, a single side surface in the transverse direction of the connection between the second layer section 1 and the first layer section 2 is welded and fixed by at least two code plates 3, and a single side surface in the longitudinal direction of the connection between the second layer section 1 and the first layer section 2 is welded and fixed by at least two code plates 3.

[0050] like Figures 1 to 8 As shown, the present invention provides a method for entering a gas equipment room, which is explained below with a specific embodiment:

[0051] The specifications of the crane vessel 5 are selected by calculating the weight of the second-layer section 1, the weight of the equipment 9 that needs to be put into the cabin, and the height of the vessel 4.

[0052] Use a suitable crane ship 5, and before the operation, adjust the crane ship 5 as follows: Figure 6 As shown, it is fixed to one side of the ship 4. The crane ship 5 is fixed to one side of the ship 4, and the crane ship 5 is a floating crane ship. The floating crane ship is fixed by four anchors 6 at four corners.

[0053] By adjusting the steel frame elevation angle of the crane ship 5, first use the auxiliary hook 7 of the crane ship 5 to lift the equipment 9, then use the main hook 8 of the crane ship 5 to lift the second-layer block 1, and vertically lift it to a safe distance from the deck surface of the ship 4. Make the lower corner of the second-layer block 1 higher than the top of the LNG tank. Use the anchor winch of the crane ship 5 to adjust the position of the crane ship 5, and install the equipment 9 after lifting it to the equipment 9 installation position on the first-layer block 2.

[0054] After the equipment 9 in the gas equipment room is installed, the second-layer total section 1 is hoisted to the top of the first-layer total section 2 , and the vertical main hook 8 is used until the second-layer total section 1 is hoisted onto the first-layer total section 2 .

[0055] Welding the welds of the second-floor section 1 and the first-floor section 2 of the gas equipment room.

[0056] Before the ship 4 is undocking, the second layer section 1 and the first layer section 2 of the gas equipment room are welded and fixed by welding through a plurality of yard plates 3 .

[0057] The present invention provides a method for bringing equipment into a gas equipment room, which fully utilizes the period of the dock stage to carry out the equipment 9 bringing operation into the gas equipment room, thereby improving the construction efficiency and achieving the purpose of reducing costs and increasing efficiency.

[0058] The present invention provides a method for loading equipment into a gas equipment room, which mainly solves the problem that the equipment 9 of the gas equipment room of a 110,000-ton dual-fuel crude oil / product oil ship cannot be hoisted in the dock stage due to late delivery, and needs to be loaded into the cabin at the dock stage. By hoisting the equipment 9 into the cabin by using a crane ship 5 at the dock stage, the node impact caused by the time problem of the equipment 9 delivery is reduced, and the strength impact and workload caused by opening a temporary process hole are reduced.

[0059] Reduce the node impact caused by the arrival time of equipment 9, reduce the workload of opening temporary process holes for equipment 9 to enter the cabin, reduce the construction difficulty, improve construction efficiency, and shorten the dock cycle.

[0060] The workload of opening temporary process holes is avoided, and the difficulty of entering equipment 9 through the temporary process holes is reduced, while the work quality and efficiency of employees are improved, which provides a basis for the entry of equipment 9 into the gas equipment room during the dock stage of subsequent new ships.

[0061] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
