Cara Menghitung Draft Surfey

Cara Menghitung Draft Surfey

Fore  = Draft Depan Kanan+Kiri : 2
After = Draft Belakang Kanan+Kiri : 2

Mid Ship Port +Stbd = Draft Tengah Kiri+Kanan : 2

Mean of Mean = (F+A) + (Mid Ship Port + Mid Ship Stbd)
                                 2                                  2

Quarter of Mean = (Mid Ship Port + Stbd) + Mean of Mean
                                                2

App Disp = Lihat Hidrostatic Table Kapal, Hasil dari Draft Rata2 Mid Ship Port / Stbd
                    badingkan dengan Displacement.

LCF = Banding dengan LCF
TPC = Banding dengan TPC
LBP = LBP kapal ( lihat di Ship Particulair)
MTC I  = Quarter of Mean + 0,5
MTC II = Quarter of Mean - 0,5

dMTC = Hasil Draft MTC I lihat MTC-nya
                Hasil Draft MTC II lihat MTC-nya

Trim = After - Fore

Trim Corr I = Trim x (+/-) LCF x TPC x 100
                                            LBP

Trim Corr II = Trim x dMTC x 50
                                    LBP

Disp Corr = App Disp +/- Trim Correction

Density Corr = 1,025 - 1,020 x Disp Corr
                                 1,025

Cord Disp (A/B) = Disp Corr - Density Corr

Bungker       =                                         (A-a) =

Fresh Water =                                         (B-b) = .................................. -

Ballast          = ................ +                      Calculated of Cargo Loaded

Total Consumables  (a/b)

Catatan :

                  Density Air Laut       = 1,020

                  Density Air Tawar     = 1,025
