Study on the Method for Calculating Ship Squat in the Restricted Channel

摘要

Safety is essential for the great ship which are sailing in the restricted channel,by estimating the squat and the Under Keel Clearance (UKC) correctly. This paperconducted the study on the method for calculating the squat in restricted channel.While the ship is sailing in the restrictive channel, the squat is affected by shipboundary layer. In this paper, hydrodynamic theory and flat boundary layer theorywere applied to put forward the approximate formula to calculate ship boundary layer.Considering the impact of ship boundary layer, the method of squat calculating wasput forward. Finally, the method was verified by real ship data.
