Calculate the Fresh Water Allowance (FWA) & Dock Water Allowance (DWA) 2 ll Calculate Final Draft
Рет қаралды 2,301
Күн бұрынCorrection 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.

Excuse me Mr. , Correctly if I'm wrong, your DWA in your second example, I think it's wrong, it's 0.109 to calculate the Arrival Draft

Yes, you are right. Thank you. The DWA should be 0.109 m not 0.136, subtract 0.109 m to the initial draft, the final draft is 10.631 m. I forgot to edit the text after I copied it from the previous example. Thank you.

Should have subtracted 0.109 from 10.740 for the 2nd example but thanks I got the concept
