Stability – I : Chapter 7

Case – 2

Ship’s weight	KG	VM
15000t	7.9m	118500tm
(+ )200t (loaded)	12m	+2400tm

Final W   =  15200                                                               Final VM = 120900 tm

We know that:-

Final KG =   (Final VM) / (Final W)
Final KG   =   (120900/15200)
=7.954m.

10. On a ship of 11000 t displacement KG7.2m a shore crane is used to shift a heavy-lift from the UD (KG 12m to the LH (KG 3m ) . Find the kg of the ship (a) during shifting is (b) after shifting .

Solution :

Case -1

Ship’s weight	KG	VM
11000t	7.2m	79200tm
(-)180t (while shifting)	12m	(-)2160tm

Final W =  10820t                                                            Final VM = 77040 tm

We know that:-

Final KG =   (Final VM) / (Final W)
Final KG   = 77040 / 10820
= 7.120m
