Abstract

Recently, the offshore plant has been revived by rise in oil prices and energy consumption. Due to the external environmental impact, the ballast system is essential for an offshore plant. The ballast system for the existing offshore plant, consist of pump 6EA and Ballast tank 4EA, is performed by the tilt control. However, this system is vulnerable to a failure due to the fact that a lot of equipment needs to be installed within the system. In this paper, a new concept of ballast system and the control algorithm based on IT is proposed. Simulator has been created to test the proposed system and algorithm, and as a result, it has proven that it is controlled stably.

최근 유가 상승과 에너지 소비 확대로 인하여 해양 플랜트가 재조명되고 있다. 이러한 해양 플랜트는 외부 환경에 많은 영향을 받기 때문에 발라스트 시스템을 이용한 자세 제어가 필수적이다. 기존 해양 플랜트의 발라스트 시스템은 펌프 6개와 발라스트 탱크 4개를 이용하여 자세 제어를 수행하였다. 그러나 이러한 시스템은 많은 장비가 설치되어야 함으로 고장에 취약하다. 본 논문에서는 새로운 발라스트 시스템과 그에 따른 IT 기반의 제어 알고리즘을 제안한다. 제안한 시스템과 알고리즘은 시뮬레이터를 제작하여 실험을 진행하였으며, 그 결과 시뮬레이터가 안정적으로 제어됨을 확인하였다.
