Simulation of Mooring Line Operation in Ship Mooring

In order to simulate the process of ship mooring more accurately, catenary equations are used to model mooring lines. Use different catenary models to simulate different phases of ship mooring operation. Establish a basic elastic catenary equation of mooring line by using the micro mechanical equilibriums theory. Then, a double-catenary model of heaving line and cable with a point load, imitating the effect of an eye splice, is developed based on existing catenary models in the literature. By calculating the mooring line tension, analyze whether the tension exceeds the safety load. The simulator is verified through simulations. A set of case studies is used to verify the effectiveness and practicability of the model. Integrate and realize the three-dimensional visualization of mooring line operation in ship mooring operation. The established model can guide mooring operation of ships. © 2021, The Institution of Engineers (India).
