- Abstract
- This study collected work data during installation of offshore structure using two crane barges considering the complex ocean environment. During the installation of the pipe as two scenarios, the ocean environment, the motion of the crane and the installation structure were measured. Buoy gathered wave, wind and current in the sea near the crane barge. The MRU(Motion Reference Unit) measured the heave, roll and pitch motion of the barge. The IMU(Inertia Measure Unit) measured roll, pitch, and yaw motion of the installation structure. In addition, video camera collected the rotation of the backstay, the rotation of the boom, and the length of the wire rope for check the scenario. The motion of the installation structure and the tension of the wire rope can be used for verification in the dynamic analysis software. ？ 2020 by the International Society of Offshore and Polar Engineers (ISOPE).
