ROV 진•회수 장치의 설계 및 동 역학 해석

Abstract

This paper is for development of ROV LARS(ROV Launching and Recovery System), based on the same as the actual product. A Lebus groove drum and an angle level winding type winch were designed for stable winding of umbilical cable up to 3000m below sea level. One of the most important features of ROV LARS is to control ROV to work with Umbilical cable stably even in rough sea conditions. It is characterized by controlling the amount of ROV heaving by wave using real-time wave data transmitted from MRU. The dynamic analysis was to verify the structural stability of the ROV LARS acting in the sea state 5 and the stability of the hydraulic system. Through the production and dynamic analysis of the ROV, it is recognized that the ROV can operate stably at 3000M underwater.
