1. Massa
bahan bakar(HFO) :
Waktu pelayaran =
Massa bahan bakar = F.c x waktu tempuh x BHP x 10-6 x 0.95 ( satuan ton)

Untuk diameter pipa pengisian pada Bunker
direncanakan 2 x dari pipa
service harian, yaitu = 45x 2 = 90 mm
Perhitungan Tebal Pelat Pipa :
S = So + c + b
So =
So =
= 0,18 mm
Jadi :
S = So + c + b
= 0,18 + 3 + 0
=
3,18 mm diambil 5 mm

hitung fuel consumptionnya gimana yaa
