Stability – I : Chapter 10

15. Vessel in same condition as in question 10, loads 1000t cargo in NO2 LH KG 4m ; 2000t cargo NO4 LH KG 5m . Find the final GM fluid, given that the final KM is 10.0m .

Solution:

Ship’s wt	KG	VM
10000t	8.954m	89540 tm
(+ ) 1000	4m	(+) 4000 tm
(+) 2000	5m	(+)10000 tm

Final W = 13000                                                          Final VM = 103540tm

We know that:
Final KG = (Final VM/ Final W)
Final KG = (103540 / 13000 )
= 7.964m

KM = 10m ( given)
Again, GM solid    = ( KM – KG)
= (10 – 7.964) m
= 2.036m

Now, FSC =( FSM/ W)
= (2087.4 /13000)
= 0.1605m

GM fluid = GM (solid) – FSC
= (2.036 – 0.1605)
= 1.875m.
