Embodiment Construction

[0022] The present invention will be further described below in conjunction with specific embodiments, but the protection scope of the present invention should not be limited by this.

[0023] Let's take a 76000t bulk carrier as an example to illustrate the manufacturing method of the segmented pre-installation of the steering gear base, including the following steps:

[0024] ① When determining the section division, the steering gear compartment deck section is to be divided into full-breadth independent sections;

[0025] ② During the production design, draw the mast layout and reinforcement drawing of the normal upper mast of the deck section (AG21 section) of the steering gear cabin;

[0026] ③ 11 sets of steering gear bases and steering gear oil storage tank bases on the deck of the steering gear cabin, rudder bearing dry oil station bases, 75KW mooring winch pumping station bases, anchor winch 400L fuel supply tank bases and related equipment bases, etc. 11 pieces The b...

Abstract

The invention discloses a ship manufacturing method for pre-mounting a steering engine base in a segmentation step. The ship manufacturing method comprises the following steps of: carrying out segmentation on a deck of a steering engine room; drawing a gantry arrangement and reinforcement picture of an upper gantry of the deck of the steering engine room at a positive segmentation state; incorporating the gantry arrangement and reinforcement picture with a segmental fitting-out tray management list so as to ensure that the pre-mounting of the steering engine base is completed in a segmental manufacturing step, and the requirement on installation precision can be met; and conveying the deck of the steering engine room in a segmental manner to a next process in a positive state of the upper gantry. The steering engine base is welded before being coated in a segmental manner, so that the segmental fitting-out integrality can be improved. Therefore, the damage area of a coating layer of a ship stern ballast cabin is reduced, the risk of sand wash on the entire ship stern ballast cabin can be effectively reduced, a coating construction period is shortened, and a PSPC (Performance Standard for Protective Coatings) can be met.

Description

technical field [0001] The invention relates to the field of ship block building, in particular to a ship manufacturing method in which steering gear bases are preassembled in block stages. Background technique [0002] The 76,000t bulk carrier currently under contract must meet the requirements of the coating protection standard (PSPC), and the steering gear base in the area of ​​the 76,000t stern ballast tank was installed at the berth / dock stage in the past, which will cause the deck of the steering gear cabin to be reversed. Large areas of paint damage in the ballast tank area, paint repairs at the berth / dock stage not only increase the workload of dock repairs, but also affect the painting effect, and the construction environment is also poor. In addition, once the ballast tank paint damage area exceeds 2% , will cause sand washing and paint repair of the entire stern ballast tank, which will have a serious impact on the construction period and construction cost of the ...
