Abstract

The International Maritime Organization is establishing international agreements on maritime safety and security to prepare for the introduction of autonomous ships. In Korea, the industry is focusing on autonomous navigation system technology development, and to reduce accidents involving coastal ships, research on autonomous ship technology application plans for coastal ships is in progress. Interest in autonomously operated ships is increasing worldwide, and maritime demonstrations for verification of developed technologies are being pursued. In this study, a basic investigation was conducted on the design of a demonstration ship and an onshore platform (remote support center) using digital twin technology for application to coastal ships. To apply digital twin technology, an 8-m small battery-powered electric propulsion ship was selected as the target. The basic design of the twin-integrated platform was developed. The ship navigation and operation data were stored on a server system, and remote-control commands of the electric propulsion ship was achieved through communication between the ship and the onshore platform. Ship performance management, operation and operation optimization, and predictive control are possible using this digital twin technology. This safe and economical digital twin technology is applicable to ships responding to crisis scenarios.

국제해사기구(IMO, International Maritime Organization)를 중심으로 자율운항선박 도입을 대비한 해사안전 및 보안관련 국제 협약을 제정하고 있다. 국내에서도 선급 및 산업체를 중심으로 자율운항시스템 기술개발에 착수하고 있으며 연안선박에서 발생하는 사고를 줄이기 위해 연안선박을 대상으로 하는 자율운항선박 기술적용 방안 연구가 진행되고 있다. 국내외적으로 자율운항선박에 대한 관심이 크게 증가하고 있으며 실제 개발된 기술의 검증을 위한 해상실증이 본격적으로 추진되고 있다. 본 연구에서는 연안선박에 적용하기 위한 디지털트윈 기술 관련 실증선박과 육상 플랫폼(원격지원센터)의 설계를 위한 기초연구를 진행하였다. 디지털트윈 기술을 선박에 적용하기 위해 8m 소형 배터리 전기추진선박을 대상으로 선정하였으며, 선박과 육상 플랫폼 간 통신을 통해 선박 항해 및 운전 데이터가 서버시스템에 저장되고 전기추진선박의 원격제어 명령이 가능한 디지털트윈 통합 플랫폼의 기본 설계를 진행하였다. 이러한 디지털트윈 기술을 적용한 선박 성능관리, 운항 및 운영 최적화, 예지제어 등이 가능할 것으로 판단되며, 위기상황에 대응이 가능한 안전하고 경제성 있는 디지털트윈 기술의 선박적용이 가능할 것이라 사료된다.
