Скачать или смотреть Calculate the Fresh Water Allowance (FWA) & Dock Water Allowance (DWA) 2 ll Calculate Final Draft

Correction to the last part of the video. The DWA is 0.109m, not 0.136m. Subtract 0.109m to the initial draft to find the final draft.

This video shows how to calculate the fresh water and dock water allowance and determine the final draft due to the change in the water density.

Fresh Water Allowance (FWA) is the number of millimeters in which the ship's mean draft changes when she passes from salt water to fresh water or from fresh water to salt water when she is loaded to its summer displacement.

Dock Water Allowance (DWA) is defined as the number of millimeters in which the ship's mean draft changes when she sails from salt water to dock water or when sailing from dock water to salt water when she is loaded to its summer displacement.
