The present invention relates to a hook-up installation procedure analysis system and, more specifically, to a hook-up installation procedure analysis system which can analyze irregular work performance by performing numerical analysis by calculating an external force including a tugboat, tidal current, and wind and then including the calculated external force in an external force term of the equation of motion in an external force analysis step. To this end, the hook-up installation procedure analysis system includes: a frequency domain analysis step of receiving an external force transfer function, a tidal wave damping coefficient, and additional mass in accordance with frequency to calculate a time series of a wave exciting force, a memory effect function, and additional mass at an infinite frequency; an external force analysis step of calculating an external force including a tugboat, tidal current, and wind; and an external consideration analysis step of performing numerical analysis by including the external force calculated in the external force analysis step in an external force term of the equation of motion. 본 발명은 후크-업(Hook up) 설치 절차 해석 시스템에 관한 것이다. 보다 상세하게는, 외력해석단계에서 바람, 조류 및 예인선을 포함한 외력을 계산한 후 계산된 외력을 운동방정식의 외력항에 포함하여 수치해석을 수행하여 불규칙한 작업 수행에 대해 해석가능한 후크-업(Hook up) 설치 절차 해석 시스템에 관한 것이다. 이를 위해 본 발명은 주파수에 따른 부가질량, 조파감쇠계수, 외력전달함수를 입력받아 무한대 주파수에서의 부가질량, 메모리영향함수, 파랑강제력의 시계열을 계산하는 주파수영역해석단계; 바람, 조류 및 예인선를 포함한 외력을 계산하는 외력해석단계; 외력해석단계에서 계산된 외력을 운동방정식의 외력항에 포함하여 수치해석하는 외력고려해석단계를 포함하는 후크-업(Hook up) 설치 절차 해석 시스템을 제공한다.
