Drawing Calculations

1. Principal DimensionTipe Kapal : Oil Carrier

Panjang (Lpp) : 172 meter

Panjang (Lwl) : 177,16 meter

Panjang (Ldisp) : 174,58 meter

Lebar

(B) : 30 meter

Cb : 0,77

Tinggi geladak (H) : 17,42 meter

Sarat air (T) : 11,22 meter

Kecepatan dinas (Vs) : 14,4 knot

2. First Calculation ( Propeller fitting & stern tube )Determine height of D:

D = 0,69 x T

= 0,69 x 11,22

= 7,7418 meter

Determine height of a :

D = 0,33 x T

= 0,33 x 11,22

= 3,7026 meter

Determine Height of D:

D = 0,12 x T

= 0,12 x 11,22

= 1,346 meter

Determine Height of b :

D = 0,35 x T

= 0,35 x 11,22

= 3,9270 meter

3. Determine The Ship Boundary AreaDetermine the height value x for main deck

x = 2,8 ( Lpp/3 +10)

= 2,8 ( 172/3 + 10)

= 188,533 mm

Determine the height value y for main deck

y = 11,1 ( Lpp/3+10 )

= 11,1 ( 172/3 + 10 )

= 747,4 mm

Determine the height value z for main deck

z = 25,0 ( Lpp/3+10 )= 25,0 ( 172/3 + 10 )

= 1683,333 mm

Determine the height value a for main deck

a = 5,6 ( Lpp/3+10 )

= 5,6 ( 172/3 + 10 )

= 377,067 mm

Determine the height value b for main deck

a = 22,2 ( Lpp/3+10 )

= 22,2 ( 172/3 + 10 )

= 1494,8 mm

Determine the height value c for main deck

a = 50 ( Lpp/3+10 )

= 50 ( 172/3 + 10 )

= 3366,667 mm

Determine the height value a for main deck

a = 5,6 ( Lpp/3+10 )

= 5,6 ( 172/3 + 10 )= 377,067 mm

Determine the postion for addition of deck value

Part of divided length = Lpp/6

= 172/6

= 28,667 mm

Determine the frame spacing for the shipao = L/500 + 0,48 [meter]

= (171,85/500) + 0,48

= 0,82 m

4. Determine the L rules (BKI)

Determine the L rules for the ship

96% Lwl = 96% x Lwl

= 96% x177,16

= 170,1 m

97% Lwl = 97% x Lwl

= 97% x177,16

= 171,85 m

Because the Lpp value is lower comparing to the L minimal as BKI regulation, so the

best L based on BKI is 171,85 m

5. Determine the Lc valueDetermine the Lc value for the ship

Hc = 0,85 x H= 0,85 x 17,42

= 14,807 m

Lc1 = 96 % Lwl (Hc)

= 96% x 180,011

= 172,81 m

Lc2 = 173,1731 m

After comparing between Lc1 value with Lc2, so Lc2 is used that is 173,173 m

6. Determine The Ship Bulkhead distanceDetermine the collision Bulkhead distance from FP

= 0,0636 . Lc

= 0,0636 x 173,1731

= 11, 02 m

Determine the Machinery space Bulkhead distance from AP

= 18,27% x Lpp

= 18,27% x 172

= 31,42 m

7. Calculation of Volume displacement & Cb

h = LWL / 20

h = 8,858 m

Volume Displacement

= 1/3 x h x 1= 47134,229 m

Coefficient Block (Cb) = Volume Displacement / (Ldisp x B x T)

= 0,80
