4. M.V HINDSHIP at a draft of F 5.38m, A 6.17m, GM
(Fluid) 0.83m FSC 0.092m
Discharges 430t from No.3 TD, Vcg 10.2m and loads
250t in No.5 LTD. 300t of fuel oil was received
equally distributed in No.2 DB tanks
Calculate her GM(Fluid).
A box shaped vessel 210 m long, 25m wide floats in
SW at a draft of 10m F KG 10Gm. An empty
mid ship compartment 30m x 25m has a W/T flat
10.Sm above the keel, find the GM?
5. A ship of 2000 tonnes displacement and KG 3.66m,
loads 1500 tonnes (KG 5.5 3500 tonnes (KG 4.60
and takes 1520 tonnes (KG 0.6 m). She discharges
2000 tonnes cargo (KG 2.44 and consumes
900 tonnes of bunkers (KG 0.40). Find the KG of the
vessel at the end of the voyage.
Explain the following x 4 12)

How to reduce grain heeling moments while
loading grain cargo?
6. A box shaped vessel 100 x 20 x 8 m floats in SW
upright at 5m draft. Find the new draft if the vessel
list 16 deg?
Will a homogeneous log 6m x 3m x 3m and relative
density 0.4 float in Fresh water with a side
perpendicular to the waterline. If not, what will be
the angle of Loll?
