The characteristics of each specialty of ship design in the three stages of detailed design, establishment and shipyard

2. Production design stage:

The production design stage is the stage to solve what method to adopt and what process to build the ship. It serves the production and construction of the shipyard. A good production design can save a lot of materials and labor costs for the shipyard.

In this stage:

1) Overall:

This major does not participate in this stage and has no workload.

2) Structure production design:

The workload of this major is the largest, focusing on the grasp of the site process, section division, lifting and closing, but in general, it is also according to the detailed drawing (the detailed design stage has been qualitative, quantitative, shaping and positioning design, but there is no three-dimensional model) to establish a three-dimensional model, and then produce the site construction drawings, which are also regular and easy to master.

3) Outfitting production design:

The workload of the production design stage of this major is ranked after the Marine engineering major, focusing on meeting the requirements of PSPC, but in general, it is also according to the detailed drawings (the detailed design stage has carried out qualitative, quantitative, shaping, positioning design, but there is no three-dimensional model) to establish a three-dimensional model, and then into the site construction drawings, the ship type is different, the difference is also large, the need to be careful.

4) Turbine production design:

The workload of this major is ranked after the structure, and it is also the most difficult and technical one in the production design stage, because the system drawings of the detailed design stage (only qualitative and quantitative design of the pipe system (only material and specifications, but no length), but not the setting and positioning design. Even if the equipment is only the approximate position) at this stage need to be lofted according to the actual size, the placement of equipment, the layout of piping, the use of all piping accessories, are considered in this stage, a lot of work in the turbine design is concentrated in the production design stage, so the need for more manpower.

5) Electrical production design:

The professional workload after the outfitting, its nature is the same as the turbine production design, detailed stage of the system drawings (only qualitative and quantitative cable (only material and specifications, but no length) design, without setting, positioning design, even if the equipment is only about the location) in this stage need to be lofted according to the actual size, equipment placement, equipment layout, equipment layout, design, design, design and design. The layout of cables and the use of all electrical accessories are considered at this stage, and a great deal of work in electrical design is concentrated in this stage of production design.

Iii. Shipyard stage:

The shipyard construction stage is the stage to solve the problem of how to build the ship. The production schedule management and safety management of the shipyard are particularly important. This stage includes the purchase of steel plates, profiles and equipment of the ship.

In this stage:

1) Overall:

This major has some workload in the completion stage, and it needs to do tilt test. Then it needs to calculate the stability of completion and load according to the weight center of gravity measured by the test, and submit it again for approval.

2) Structure:

This specialty requires the control of drawing quality, feedback of problems, procurement of steel plates and profiles, etc.

3) Outfitting:

This major needs to control the quality of drawings, feedback on problems, equipment procurement, etc. The more equipment, the greater the workload.

4) Turbine:

This major requires the control of drawing quality, problem feedback, equipment procurement, etc. The more equipment, the more workload, so the shipyard (on-site) engineers are basically the most people.

5) Electrical:

This major needs to control the quality of drawings, feedback on problems, equipment procurement, etc. The more equipment, the greater the workload.
