There is a number of ports where approach or inside navigation channels are located close to the quay walls. In difficult hydrometeorological conditions appropriate speed of ship is needed to keep proper ship’s steering while passing through channel. The ships that pass near the quay walls with high speed create high interaction forces on moored ships and negatively interact on their mooring equipment and quay walls. Ports should ensure relevant maintenance and reliability of quay walls and ships’ mooring equipment. That is why investigation of the ships interaction forces during ship passing near the ships moored to quay walls is very important to find limitations of the passing ship speed depending on passing ship’s parameters, distances ...
