KRISO Takes on Intelligent Navigation of Autonomous Navigation Ships

▶ From intelligent route determination to digital twin bridge/engine monitoring

▶ Technology application expected for the demonstration of an autonomous ship planned for launch at the end of 2021

▶ System advancement through the establishment of the Autonomous Ship Performance Demonstration Center in June 2022



The Korea Research Institute of Ships and Ocean Engineering(KRISO, President Booki Kim) is accelerating the research and development of autonomous ships.


Autonomous ships are next generation high-value-added ships that replace the decision-making of the crew with intelligent and autonomous systems through the convergence of artificial intelligence(AI), Internet of Things(IoT), big data, and sensors. Recently, development of autonomous ships has been competitively pursued worldwide, along with the 4th Industrial Revolution.


In Korea, the Korea Autonomous Surface Ship Project was initiated in 2020 led by the Ministry of Trade, Industry and Energy and the Ministry of Oceans and Fisheries. Within the project, KRISO is responsible for research on autonomous navigation system development, situational awareness system development, establishment of the foundations for performance demonstration, and international standardization.


As a part of the autonomous navigation system development research, KRISO conducted testing on the “intelligent route decision-making” algorithm and system as a part of autonomous navigation system development. “Intelligent route decision-making” is a core technology of the autonomous navigation ship that encompasses the research and development of the autonomous navigation algorithm and system including the economic navigation module, safety navigation module, and intelligent route determination module.


The economic navigation module automatically sets the optimal economic route and the safety navigation module enables the avoidance of potential collision risks on the navigation route and responds to violations of navigation regulations by other ships. Also, the intelligent route determination module can be used to substitute the judgment of the ship operator.


In order to verify the performance of the safety navigation algorithm and system stability of the autonomous navigation ship, KRISO conducted testing including the real-time generation and operation of safe routes in encountering situations of various ocean conditions, such as waves and 2m model ships, in the KRISO ocean engineering basin.


The autonomous navigation ship algorithm and system in development by KRISO differentiates themselves through detailed technologies and test environments.


Going beyond the limited situation of encountering a single ship (COLREG* regulation applied), the technology to create and follow safe navigation routes is incorporated even when encountering 3 or more ships simultaneously.

Additionally, by verifying the performance of the core algorithm and system in the ocean engineering basin, which can reproduce actual ocean environments including waves, wind, and tides, the reliability of the advanced route decision-making technology for active/intelligent determination of navigation routes depending on the situation can be further improved.


Along with the algorithm and system performance testing, KRISO developed a digital twin bridge/engine monitoring system that can remotely monitor the test situation and performance demonstration of the autonomous navigation ship.


The digital twin bridge/engine monitoring system is a system that can check the demonstration process of the ship by monitoring the various data throughout the demonstration process of the autonomous navigation ship on the ground in real-time.


This system is planned for final establishment in the autonomous navigation ship performance demonstration center at Goneuljigu in Ulsan in June 2022. The role of the system is highly anticipated as it allows for remote monitoring as well as remote operation of the autonomous navigation ship at sea.


KRISO President Booki Kim said, “Development of the intelligent route decision-making algorithm and system, which are key technologies of the autonomous navigation ship, is progressing smoothly, and these technologies are planned for application to the autonomous navigation test ship that will be launched at the end of this year for demonstration at sea.”
