MODEL PA 6B L,V

POWER 5600 KW

No.Of.CYLINDER 16 V

POWER PER CYLINDER 350 KW

RPM 900 ( 350)

LENGTH 9.854 Mts.

BREATH 2.0 X 2.21 Mts.

HEIGHT 3.561 Mts.

WEIGHT 65 Mton.

BORE 280 mm

STROKE 330 mm

Specific Fuel Oil Consumption (SFOC)

g/kWh 171 159 171 159

Lubricating and Cylinder Oil Consumption

Lubricating oil 4 - 5 kg/cyl. 24 h

Cylinder oil 0.7 - 1.5 g/kWh

Auxiliary Engine:

2880 = k 2/3 V3

= k 71522 2/3 15.23

EP*= k 2/3 V3

= k 22867.34 2/3 183

EP*= 2236 kw

Auxiliary power: 2 wartsila 6L20 + 1 wartsila 4L20

= 2 790 + 1 670

= 2250 kw

Weight and displacement

Steel weight

So the average steel weight is about 3742.7 tonnes

Outfitting weight

Wo*= Wo L* B* / L B

Machinery weight

Wm = {MCR*/MCR}

Light ship weight = Ws+Wo+Wm=3742.7 + 795 + 772.2 =5309.9

Estimation of fuel, water consumption and ballast weight

In a return trip the distance is 6480 nautical mile

Time to be taken is 360 hours which is equal to 15 days at sea

And also assume that the in port time is 24 hour for 3 port and 9 hours for

maneourving.

Calculation about the tank sizeroute of the ship: 6480 n.m.
