Automation and Control Systems Technology in Korean Shipbuilding Industry: The State of the Art and the Future Perspectives

Abstract Owing to the steep rising of marine cargo transportation with the growth of global economy and the increasing demands for replacing overage vessels, the shipbuilding industry meets historic boom days with record-breaking order backlog. To fortify the leading position in the market with improved productivity and high quality, Korean ship construction companies vigorously pursue researches on shipbuilding automation and ship automation technologies. This talk introduces the recent issues and efforts on automation and control system technology in Korean shipbuilding industry.

Systematic study on the hull form design and resistance prediction of displacement-type super-high-speed ships

Systematic theoretical and experimental studies were carried out to establish methods for hull form design, optimum dimension selection, and resistance estimation for displacement-type super-high-speed ships. In this study, a theoretical hull form design method for displacement-type super-high-speed ships was first developed using the minimum resistance theory and a sectionally varying hull form equation. Using an established hull form design method, a series of 60 hull forms were prepared with systematic variations of the most important design variables, and model tests were conducted for these ship models. Finally, regression analyses were performed for the results of the model tests. The study was very successful, and the prepared computer programs are now being actively used as efficient tools for the design of the displacement-type super-high-speed ships.
