“…Ship mooring manipulation simulation should achieve engineering demonstration and navigation safety assessment, and be competent for training and teaching proposed by International Convention on Standards of Training, Certification and Watch keeping for Seafarers (STCW). The researches on ship mooring system can be divided into three categories: (1) Accuracy and scientificity of the mooring system [1]. (2) Maneuverability under various conditions [2].…”

The Position-Based Dynamics (PBD) method considers the rope as a series of particles in rope simulation. This paper introduces the PBD method and simulates mooring line in ship mooring simulation training system with four constraints, which are distance constraint, bending constraint, Long Range Attachment (LRA) constraint and pin constraint. In this paper, the LRA constraint method is applied to solve the overstretch problem of mooring line simulation caused by distance constraint and bending constraint. A pin constraint which combines two particles into one is put forward to achieve the connection effect between cable and the eye splice as well as the interaction between anchor and chain. Moreover, the method of Continuous Collision Detection (CCD) constraint is proposed to realize the collision detection between mooring lines and other objects. Compared with Newton's method, our adopted method is more efficient and robustness. Since it has sufficient visual plausibility and can realize real-time visualization, the simulation system developed by PBD method has a good training effect for crew.INDEX TERMS Ship mooring maneuvering, mooring lines, position-based dynamics, constrained dynamics, system simulation.

The good performance of the port activities in terminals is mainly conditioned by the dynamic response of the moored ship system at a berth. An adequate definition of the highly multivariate processes involved in the response of a moored ship at a berth is crucial for an appropriate characterization of port operability. The availability of an efficient forecast system of the movements of moored ships is essential for the planning, performance, and safety of the development of port operations. In this paper, an inference model to predict moored ship motions, based on a semi-supervised Machine Learning methodology, is presented. A comparison with different supervised and unsupervised Machine Learning techniques, as well as with existing Deep Learning-based models for predicting moored ship motions, has been performed. The highest performance of the semi-supervised Machine Learning-based model has been obtained. Additionally, the influence of infragravity wave parameters introduced as predictor variables in the model has been analyzed and compared with the typical ocean waves, wind, and sea level as predictor variables. The prediction model has been developed and validated with an available dataset of measured data from field campaigns in the Outer Port of Punta Langosteira (A Coruña, Spain).
