Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] The 50,000-ton semi-submersible ship master diesel generator set entry process of the present invention includes the following steps:

[0033] 1) Select the entry position, combine the equipment delivery schedule of the main diesel generator and the segment loading plan, and enter from the segment closing port;

[0034] 2) Determination of the way of entering the cabin ， With the help of tooling, the main diesel generator is pulled in horizontally from the segmental closing port by sliding into the cabin;

[0035] 3) Prepare the entry conditions of the main diesel generator set, according to the basic parameters of the main diesel generator, the size of the segmental closing opening, the size of the engine room and the actual construction environment on site, combined with the obstacles on the hoisting and entry lines of the hull structure Temporaril...

Abstract

The invention discloses a cabin entry process for a main diesel generating set of a 50,000-ton semi-submerged ship. The cabin entry process comprises the following steps of: 1) selecting a cabin entry position and entering from a sectional folding port; 2) determining a cabin entry mode and horizontally pulling in by using a tool; 3) preparing for a cabin entry condition of the main diesel generating set; 4) preparing for cabin entry of the main diesel generating set, and arranging a rail, wherein two strips of sectional transverse H-shaped steel are arranged on the two sides of the rail; 5) lifting the main diesel generating set by using a gantry crane; 6) connecting a hoist, slowly pulling the main diesel generating set into a cabin by using the hoist, and checking a folding condition of a host pedestal and the rail at any time to prevent paint on a base of the main diesel generating set from being scratched; and 7) dragging the main diesel generating set out of the rail when completely reaching a preset mounting position. By the cabin entry process, the disassembly work of a cabin structure and pipe outfitting can be reduced, safe and high-efficiency cabin entry and completeness of the structure and the outfitting are guaranteed, and the workload is reduced.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a process for entering a cabin of a 50,000-ton semi-submersible main diesel generator set. Background technique [0002] The 50,000t semi-submersible ship is equipped with double propellers, double rudders and double bow thrusters. It is an electric propulsion ship powered by 4 diesel generator sets, and the weight of each main diesel generator is 71.85 tons; the maximum external dimension: length 10200mm, height 4080mm, width 2690mm. Therefore, as an important production node, the entry of the main diesel generator will have a significant impact on the entire production schedule. In order to improve the efficiency and safety of the main diesel generator entry and ensure the progress of shipbuilding, it is necessary to study the entry process And analyze the construction plan to solve the practical problem of safely and quickly sliding the generator into the engine room. T...
