Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a method for mounting an oil collecting tank in a manifold area of ​​an oil tanker. Background Art

[0002] At present, after the oil collecting tank is installed on the hull, various iron outfittings need to be installed on the oil collecting tank. The installation of iron outfittings will cause damage to the paint on the surface of the oil collecting tank. Since the paint requirements of the oil collecting tank are usually high, in order to reduce the paint re-coating caused by the assembly of iron outfittings, the oil collecting tank is generally only primed in the workshop before it is installed. After the empty ship test of the ship is completed, the oil collecting tank together with the iron outfittings above will be hoisted off the ship as a whole and transferred to the sand room for sand washing and painting. After the painting is completed, it will be hoisted back on board for installation. This process causes the oil collecting tank to be repeatedly installed, low work efficiency, and waste of a lot of manpower and material resources. Summary of the invention

[0003] The purpose of the present invention is to provide a method for loading oil collecting tanks in a tanker manifold area, which avoids repeated loading of oil collecting tanks, significantly improves work efficiency, and can save a lot of manpower and material resources in view of the shortcomings of the prior art.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the method for loading the oil collecting tank in the manifold area of ​​an oil tanker of the present invention is:

[0005] A method for loading an oil collecting tank in a manifold area of ​​an oil tanker comprises the following steps:

[0006] S1. Making the oil collecting tank unit module: The oil collecting tank unit module includes the oil collecting tank body, and the oil collecting tank body is equipped with a handrail, an inclined ladder ear plate, a lifting ear, a pipe bracket, a discharge pipe, a lamp holder, and a wire rope handrail column;

[0007] S2, spraying: send the oil collecting tank unit module completed in S1 to the sand room for sand washing and painting to achieve the finished paint state;

[0008] S3, equipped with:

[0009] S31, using the lifting lugs to lift the oil collecting tank unit module to the vicinity of the installation location;

[0010] S32, positioning the oil collecting tank unit module according to the design drawing;

[0011] S33, after the positioning is completed, welding and assembly of the oil collecting tank body foot begins;

[0012] S34. Wrap and protect the assembled oil collecting tank unit module.

[0013] Preferably, step S32 also includes checking whether the base of the oil sump body is aligned with the reinforcement ribs on the back of the deck. If there is any misalignment, the position of the reinforcement ribs on the back of the deck is adjusted to make it correspond one-to-one with the base of the oil sump body.

[0014] Preferably, in step S2, only the shop primer is applied to the section 30-50 mm from the bottom of the oil collecting tank body foot.

[0015] Preferably, in step S34, a three-proof cloth is used to wrap and protect the oil collection tank unit module.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] First, install the railings, inclined ladder ears, lifting ears, pipe brackets, discharge pipes, lamp holders, and wire rope railing columns on the oil sump body to form an oil sump unit module. The entire module is sandblasted and painted, and finally the module is mounted on the hull at one time without disassembly for secondary loading, which saves a lot of manpower and material resources and significantly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a flow chart of the method for loading oil collecting tanks in the manifold area of ​​an oil tanker according to the present invention.

[0019] Figure 2 It is a structural schematic diagram of the oil sump unit module.

[0020] Among them, 1 is the oil collecting tank body, 2 is the handrail, 3 is the inclined ladder ear plate, 4 is the lifting ear, 5 is the pipe bracket, 6 is the discharge pipe, 7 is the lamp holder, and 8 is the wire rope handrail column. DETAILED DESCRIPTION

[0021] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0022] like Figure 1-2 As shown, a method for loading an oil collecting tank in a manifold area of ​​an oil tanker comprises the following steps:

[0023] S1. Make the oil collecting tank unit module: The oil collecting tank unit module includes an oil collecting tank body 1. According to the design drawing, a handrail 2, an inclined ladder ear plate 3, a lifting ear 4, a pipe bracket 5, a discharge pipe 6, a lamp holder 7, and a wire rope handrail column 8 are installed at the corresponding position of the oil collecting tank body;

[0024] S2, spraying: send the oil collecting tank unit module completed in S1 to the sand room for sandblasting and painting, and achieve the finished paint state; in order to reduce impurities and ensure welding quality, only the 40mm section from the bottom of the oil collecting tank body foot is painted with workshop primer as a welding reserve;

[0025] S3, equipped with:

[0026] S31, using the lifting lugs to lift the oil collecting tank unit module to the vicinity of the installation location;

[0027] S32. Position the oil collecting tank unit module according to the design drawings. During positioning, check whether the oil collecting tank body foot is aligned with the deck back reinforcement rib. If there is any misalignment, adjust the position of the deck back reinforcement rib to make it correspond to the oil collecting tank body foot one by one.

[0028] S33, after the positioning is completed, welding and assembly of the oil collecting tank body foot begins;

[0029] S34. Wrap the assembled oil collecting tank unit module with three-proof cloth for protection to prevent large-scale rusting due to deck construction and other reasons in the later stage.

[0030] The present invention completes the assembly of the oil collecting tank body and the iron outfitting before the oil collecting tank body is mounted on the hull, thereby forming an oil collecting tank unit module, that is, completing the sandblasting, painting and mounting on the hull in a modular form, thereby avoiding the process of dismantling the oil collecting tank body after the empty ship test of the ship, and then mounting it again after painting, thereby saving a lot of manpower and material resources, significantly improving work efficiency, and shortening the shipbuilding cycle.
