Prediction of load on mooring ropes of a container ship due to the forces induced by a passing bulk carrier [PDF]

, 2003
The hydrodynamic surge and sway forces and yaw moment on a moored ship induced by a anothership moving near and parallel to it are estimated. The results are compared with the values obtained byexperiments carried out in the Towing tank for manoeuvres in
