Abstract
An experimental model was constructed to simulate the forces
affecting upon ships inside the navigation locks under a relatively new method
of filling and emptying process laid in the chamber floor. The tests were
carried out for three different positions of the ship affixture inside the lock
chamber with respect to the filling system. In each position, both the
longitudinal and the lateral forces affecting upon the ship were measured by
using advanced electromagnetic system of pressure transducers connected
with a data logger and personal computer for the two cases of the ship
orientation. In the first case of orientation, the bow faced the openings of the
filling system, while for the second one the stern of the ship faced the filling
system. The study illustrated that the longitudinal forces on the ship were
much more greater than the lateral ones. It was found also that the forces
affected upon the ship in case of filling process was much more greater than
that in the emptying one. The analysis of the results showed that the critical :
position of the ship affixture inside the lock chamber occurred when the ship
was closed to the filling system. Also, the stern of the ship was more critical
than that of the bow when facing the openings of the filling system.
