Recently, the fourth industrial revolution has resulted in a paradigm shift to the development of information and communication technology and smart technology, which has extended to the shipbuilding industry worldwide. The Korean shipbuilding industry employs a high level of smart application technology, smart production technology, and smart ship platforms, which have been extended to all areas in the value chain, resulting in relatively high added value. The project "The Smart K-Yard" was conceived to achieve growth in the productivity of Korean small and mediumsized shipyards. This project is necessary to eliminate elements of waste and minimize the work force, thereby reducing the production lead-time and enhancing the quality of intelligent and smart shipbuilding production system. The project uses automation technology and simulation-based test bed for the shipbuilding processes. It has five work packages: 1) intelligent shipbuilding production design platform, 2) shipbuilding process automation technology, 3) shipyard operational efficiency improvement technology, 4) simulation-based virtual production platform, and 5) Smart K-yard supporting and training center using digital twin and cyber-physical system to improve and maintain the level of skills. In this paper, the development of unmanned vessels control system as part of future ships in South Korea is introduced. The system is divided into the hull, propulsion system, steering system, control system, and power system. The main controller for the engine, waterjet, and power has been developed. Moreover, the reliability and usefulness of the systems were verified using test beds and water tank testing. We plan to continue the development of advanced technology for unmanned vessel, including determining the appropriate safety improvement method to be implemented in the event of damage caused by abnormal condition and operator's negligence during operation and maintenance of equipment as an unmanned vessel is equipped with more communication related devices and electronic equipment than a manned vessel. Technological cooperation for future ships focusing on industrial internet of things (lloT) sensor technology, robotic system, and unmanned vessels is increasingly necessary among different countries. As such, we highlighted the need to increase information technology cooperation between research institutes, universities, and relevant companies in Finland in response to the fourth industrial revolution of shipbuilding industry.
