Ship Simulation Module Robot Arm
The large hydraulic robotic arm for ship simulation is a 5 degree-of-freedom (DOF) robotic system developed to simulate a Ship-to-Ship LNG bunkering transfer system package for testing purposes on land. This system utilizes liquid nitrogen (LN2) as the test fluid, enabling thorough performance and safety testing and analysis of LNG bunkering transfer system equipment.
This robotic arm can simulate the relative motion between two ships in offshore environments under wave conditions of up to 2 meters, utilizing 5 degrees of freedom(DOF). Its dynamic motion range spans 6.4m × 6.4m × 4m in the X, Y, and Z directions, and it precisely replicates ship movements with forces of 10 kN, 10 kN, and 40 kN. To ensure accurate motion simulation, advanced robotic technologies such as real-time multi-axis coordinated control, inverse kinematics algorithms, and vibration-suppressing hydraulic control are employed. It is installed outdoors at Gyeongnam Technopark, designed to enable stable testing under various external environmental conditions, such as sea fog, temperature variations, humidity, and dust. Additionally, the system is capable of simulating LNG-powered ships of various sizes and includes a rigid structural design that accurately replicates drift and fluctuation phenomena caused by currents and waves.
This large hydraulic robotic arm can simulate the movement of large vessels affected by waves in port environments, providing an optimal testing environment for verifying the performance and safety of the bunkering system. This validation system is expected to significantly enhance the efficiency and safety of marine bunkering operations.
