A Study about the interactions of vessels running parallely in proximity to one another and safe conducting of them in restricted waterways
Chun-Ki Lee
Abstract
When a vessel passes near a channel boundary, the boundary creates forces and moments acting on the vessel. With the same reason passing of two vessels closely gives same effects to each other. The principal difference between the above two cases is that the channel boundary is long and constant shape compαred to those of vessels. The interaction forces and moments between two vessels could be assumed to be functions of the longitudinal distance χ₀, transverse distance y₀ and speeds of the two vessels. Passage of two vessel close to another is important operationally from the viewpoint of replenishment at sea, avoidance of collisions and passage of two vessels in restricted channels. The authors studied the interactions between two vessels running closely and calculated safe conducting distances according to separated distances and speeds of the two vessels.
Key Words: Safe conducting distance;Interaction forces between two vessels;Separated distance between two vessels;Ship’s speed
