Abstract

The invention discloses an assembly process visualization method suitable for large-scale marine oil and gas core module equipment. The assembly process visualization method comprises the following steps: step 1, representing an assembly information model of the equipment by adopting a hierarchical model; step 2, carrying out assembly sequence planning on the assembly body; 3, assembly path planning is conducted on the parts in a man-machine interaction mode; and 4, completing ergonomic simulation, and outputting a visual file. According to the method, the digital equipment assembly working mode is achieved, the whole assembly process is more accurate, the assembly cost is greatly reduced, the efficiency of field workers is improved through an adopted assembly process visualization system,errors and injuries of operators during assembly are prevented, the overall safety coefficient is improved, and the construction requirements of technicians are reduced.

During the entire offshore equipment assembly process, the process document is the main basis for on-site assembly personnel, so its visualization method and degree will greatly affect the efficiency and quality of equipment assembly

[0003] At present, many domestic industries have realized digital design and analysis technology solutions with 3D technology as the core, but the assembly process design and implementation process of large-scale offshore oil and gas core module equipment still adopts the tradition of 2D process design, expression and physical verification. Means, this traditional assembly process visualization method uses a two-dimensional view of the product combined with text descriptions to guide workers in assembly operations, which requires workers to spend a lot of time and energy on interpreting and digesting two-dimensional drawings before assembly. Operation, and this workload is quite large for the assembly of complex products. Workers are slow to master the assembly sequence of new products, and mistakes in installation and operation will occur.

In the digital development process of offshore engineering manufacturing, it is still in a relatively lagging state, so there are many technical coordination problems in the assembly process of offshore oil and gas core module equipment. The process design optimization cycle is long, the amount of rework and repair caused by design changes is large, and the number of scrapped parts is large, which seriously affects the progress and quality of offshore oil and gas module equipment development. It has always been a technical bottleneck that plagues the development of large-scale offshore oil and gas core modules.
