Ship’s Girder Deflection

Which are the main data input?

At the top of the main Ship’s Girder Deflection screen, if “Given Draft Mark Readings” tab is selected,
input of the Draft Aft, Amid and Fwd at both Port and Starboard Side at Mark Readings, shall be inserted
at the respective fields.

Next, if thermal deflection needs to be determined, you may input data for Air Temperature and
Seawater Temperature for Thermal Deflection Calculations, in order to find the total Deflection at
Midship and eventually the total DWT Gain/Loss.

Otherwise, you may select the tab “Given Draft Amid and Deflection”, if deflection at Midship can be
already determined from existing instruments onboard. In that case the Draft Amid (Loading
Instrument) and Deflection at Midship shall be inserted at the respective fields.
Also, Sagging or Hogging Condition shall be defined.

Likewise, if thermal deflection needs to be determined, you may follow the above steps as being
described in “Given Draft Mark Readings” steps.

How the results are illustrated?

The calculated Deflection and the Deadweight Gain or Loss are displayed in the Table Results for both
Options. 

At the bottom of the Table results screen, the Thermal Deflection at Midship and the total Deadweight
Gain or Loss are illustrated.
