  7. Abstract:
  8. One of the most significant challenges and issues that port engineers and coastal specialists face in the field of improving port performance is the design and development of hardware systems to enhance the efficiency of loading and unloading operations of ships. These systems need to be designed in a way that reduces the duration of loading and unloading operations of ships and improves the efficiency of cranes. One efficient technology in this field is the Automatic Mooring Systems, which are connected to the hull of berthed ships and use hydraulic cylinders to generate control forces. On the other hand, as evident in today's world, artificial intelligence is recognized as a vital and key knowledge used in various industries and fields. Among the main goals of this project, alongside the initial and conceptual design of an automated mooring system, is the integration of artificial intelligence with this system to predict forces acting on the moored ship and neutralize it for stabilizing the moored vessel. For this prediction, a combination of satellite data from the operational area and machine learning models has been utilized. To create a comprehensive data list and develop a mechanism for predicting forces entering the floating structure and applying stabilizing forces to the ship, satellite data, including information such as wind speed, wave height, and wave period in the operational area of Bandar Abbas, is collected. Subsequently, aiming to create a comprehensive data list of 36 different maritime conditions on 10 types of floating structures with varying weights and lengths, 360 simulations are performed in Ansys Aqua software for extracting forces acting on the floating structures. Furthermore, using machine learning methods, various machine learning models have been trained based on the created data list. The performance of these models will be compared, and the best model will be selected. In the next step, the conceptual design of the mooring mechanism in SolidWorks software will be addressed, and the kinematic and dynamic equations related to it will be extracted in Matlab software. The movement of the mechanism will be examined using Simulink by applying various inputs to the mechanism joints through simulation
