Off-shore plant means all kinds of business including equipment and facilities for excavating, drilling, and producing marine resources such as oil and gas buried in the sea. It can be divided into drilling type and production type according to the use, and can be divided into fixed type and floating type according to the installation method. Offshore plants have been mainly carried out by large shipyards at home and abroad, and due to the recent global downturn in the offshore plant industry, interest in localizing offshore plant facilities and strengthening competitiveness of domestic companies differentiated in design and production technology is growing.

However, the market for offshore equipment products is already dominated by global advanced companies, and even in the basic and production design fields, the Plant Design Management System (PDMS) developed by AVEVA Marine is exclusively used in the overall plant layout design and review. is being used as For this reason, it is difficult to overcome the barriers to entry into the global market after developing and localizing program products necessary for offshore plant structure design.

In order to strengthen the competitiveness of small and medium-sized enterprises (SMEs) that support detailed and production design of offshore plants, it is necessary to make efforts to secure independent technology to improve design efficiency and minimize design time. The conventionally used PDMS is a dedicated 3D CAD program for plants used in the overall range from basic to production design of offshore plants. Although the conventional PDMS is the most commonly used program in the design process of offshore plants, the sequential design process is complicated, cumbersome, and repetitive when applied to complex design practices in each field, such as structure, battlefield, captain, captain, and design. There is a problem that the efficiency of the work decreases because there are many
