Question From Readers #18: Fresh Water Allowance And Dock Water Allowance Formula

Fresh Water Allowance And Dock Water allowance Formula

A vessel has a mean draft  of 25'-00", her displacement is 10000 tons and the TPI is 42. Find the increase of draft in a water density 1010 kgs/m³.

Given:

 Displacement = 10, 000 tons
Water density = 1010 kgs/m³
                TPI = 42

Solution:

We are going to use two formulas to solve this problem.

1.    Fresh Water Allowance = Displacement
                                              40 x TPI
                                          = 10000   tons
                                              40 x 42 tons per inches immersion
                                          = 5.95 inches

2.                              DWA = FWA x (1025 - New Density)
                                                              25
                                          = 5.95" x (1025-1010)
                                                       25
                                          = 3.57" is our final answer
