【Abstract】 An equation is introduced in this paper to describe the shape of the mooring line which is lead from a fair leader to a bollard. The tension of the line is then calculated in accordance with the locations of the fair leader and the bollard, considering the transformation of the line due to the tension. The relationship between ship movement and the tensile force is still analyzed in the case of different length of the mooring line. The numerical results show that longer, better elasticity and heavier mooring lines take higher efficiency to fasten the ship: being good for absorbing the kinetic energy of the ship and moderating the impact on the line, opposite to the shorter,worse elasticity and lighter ones.更多还原
