On a ship of W 5000t , GM 0.3m, 20t was shifted transversely by 5m. Find the list.
Solution:
W = 5000t, GM = 0.3m,
Weight shifted (w) = 20t & d= 5m
Listing moment = (20 x 5 )
= 100tm
We know that :
Tanθ = ( Listing Moment) /(W x GM)
= 100/(5000 x 0.3)
= 3.8 degree.

On a ship of W 8000t, GM 2.0m, If the following transverse shifting were done , find the list:
 200cargo shifted 4m to stbd
 100t cargo shifted 2 m to port
 100t cargo shifted 4m to port
 50t stores shifted 20m to stbd
Solution:
We can calculate Listing moment due to shifting of cargo
LM(1) = ( weight x distance )
= (200 x 4)
= 800 tm (S)
Again, LM (2) = (Weight x distance )
= (100 x 2)
= 200 tm (P)
LM(3) = ( weight x distance )
= (100 x 4)
= 400 tm (P)
LM(4) = ( weight x distance )
= (50 x 20)
= 1000 tm (S)
Final listing moment (LM) = LM(1) + LM(2) +LM(3)+ LM(4)
= 800(S) + 200(P) + 400(P) + 1000(S)
=1800(S) + 600(P)
So, final listing moments = (1800 – 600)
= 1200 tm (S)
Now, Tanθ = (Final LM )/(W x GM)
= (1200/(8000 x 2 )
= 4.29 degree (S)

If 200t cargo was shifted downwards by 10m and to starboard by 5m on a ship of W 10000t , KG 7.0m, KM 7.4m, find the list.
Solution :
Given :
Cargo shifted (w) = 200t,

We know that:
Final KG = (final VM)/ (Final W)
Final KG = (68000/10000)

Final GM= (KM – KG)
= (7.4 – 6.8)

Listing moment (LM) = (weight x distance )
= (200 x 5)
= 1000tm
tanθ = LM/(W x GM)
= 1000 /(10000 x 0.6)

A quantity of grain estimated to be 100t shifts transeversly by 12m and upwards by 1.5m, on a ship of W 12000t , GM 1.2m. Find the list caused.
Solution:
Grain shifted (w) = 100t,
Distance = 12m & transversely, d = 1.5( î)
W = 12000 t, GM = 1.2m
LM caused = (weight x distance)
= (100 x 12)
= 1200 tm
GG1 (î) = (distance x weight) /W
= (1.5 x 100) / 12000
= 0.0125 m
Final GM = (GM – GG1)
= (1.2 – 0.0125)m
= 1.1875m
Tanθ = LM /(W x GM )
= 1200/(12000 x 1.1875)
= 4 degree 8’.

Final GM = (KM –KG)
= (8.935 – 7.935)

A ship listed 8degree to port , displaces 12000t and has KM 7.54m and KG 6.8m . Find how many tonnes of SW ballast must be transfered from NO 2 port DB tank to NO2 stbd DB tank , to up right and vessel , if the tank centre are 10m apart .
Solution :
List = 8 degree (P) ,
Displacement (W) = 12000t,
KM = 7.54m &
KG = 6.8m
We know that:
GM = (KM – KG)
= (7.54 – 6.80)
= 0.74m
Again, listing moment (LM)= (W x GM x tanθ)
= (12000 x 0.74 x tan8^{0})
= 1248 tm
We know that ,
Listing moment (LM) = (W x D)
1248 tm = (W x 10m)
So, W = 124.8 t
Here to upright the vessel the lighting moment caused on particle must be same at stbd side. So we have to transfer 124.8t of sea water to the stbd side of DB tank to upright the vessel.

A ship displacing 4000t has GM 1.0m (KM 10.0 m and KG 9.0 m) and is listed 10 degree to port .If 16000t of cargo is now loaded on the centre line and the final GM is 1.0m KM 9.0m and KG 8.0m state weather the list would change .if yes , find the new list .
Solution :
Displacement (W) = 4000t,
GM = 1.0m (initial) ,
list = 10 degree (P)
W = 16000t, G
M = 1.0m (final)
We know that:
Listing moment (LM) = (W x GM tanθ)
= (4000 x 1 x tan 10^{0})
= 705.3 tm
According to question , 16000 t of cargo loaded
So Final W = (16000 + 4000)
= 20,000t
But, Initial GM = Final GM
Initial LM = Final LM
Again we know that :
Tanθ = (FLM/(W x GM )
= 705.3/(20000 x 1)
= 2 degree 1 minute ( P).
Hence we can say that,(Yes) list would change due to the loading of cargo.

A ship of W 10000t. GM 1.5m, is listed 5 degree to stbd . If cargo is shifted vertically until her final GM is 0.5m, state whether the list would change . if yes find the new list .
Solution :
Displacement (W) = 10000t,
GM = 1.5m,
list = 5 degree
Final GM = 0.5m
We know that :
Listing moment (LM)= (W x GM tanθ)
= (10000 x 1.5 x tan5^{0} )
= 1312.33 tm (S)
According to question, cargo shift vertically and now GM becomes 0.5 m
Hence, Due to change of GM , list must be change .
We know that:
Tanθ = LM / (W x GM)
= 1312.33/(10000 x 0.5)
= 14.7dgree stbd

Final GM = (KM – KG)
= (9.3 – 8.5)

A ship of 15000t displacement, KG 8.7m KM 9.5m is listed 10deg to port. The following cargo work was carried out:

 300t discharged, KG 4.0m, 4 port of CL.
Find the quantity of SW ballast that must be transferred transversely to bring the vessel up right , the tank centres the being 12m apart.
NOTE : Since vessel is required upright , it is not necessary to calculate the final KG or GM unless specifically asked).
Solution:
Displacement (W) = 15000t,
KG = 8.7m, KM = 9.5m & list = 10 degree (P)
Final W = (15000 + 500) – 300 = 15200 t
Initial LM = 15000 x 0.8 x tan 10 = 2115.9 tm (P)
We know that:
Listing moment caused
LM(1) = (500 x 5)
= 2500 tm (S)
LM (2) = (300 x 4)
= 1200 tm (S)
Total listing moment = (2500 + 1200) tm
= 3700 tm (S)
According to question and calculation done above ,
Initial listing moment = 1584.1 tm (S)
So, maintain vessel upright same LM must be created on (P) side.
Again, we know that LM = w x d
1584.1 tm = (w x 12)
= (1584.1/12)
= 132 t
Hence , 132t SW should transferred to (P) side to keel the vessel upright.

We know that :
Final KG = (Final VM) /(Final W)
= (118310/13250)
= 8.929 m
Again,
Initial LM = ( W x GM tanθ)
= (12250 x 0.8 x tan 6.5^{0})
= 1116.57 (S)
GM = ( KM – KG)
= (9.6 – 8.929)

We know that:
Final KG = (Final VM)/(Final W)
= (64000 – 10X)/(8000 –X)
Again, Final GM = (KM – Final KG)
= 8.6 – (64000 – 10X )/(8000 – X)
= 8.6 (8000 X ) – (64000 – 10X) /(8000 –X)
= (68800 – 8.6X – 64000 + 10X)/(8000 – X)
= (4800 + 1.4X)/(8000 – X)
We know that:
Tan θ = (Final LM)/ (Final W x Final GM)
= 8X / ((8000 – X ) x (4800 + 1.4X)/(8000 –X))
= 8X /(4800 + 1.4X)
8X = tan 3^{0} x (4800 + 1.4X)
= (251.56 + 0.073X)
(8X – 0 .073X) = 251.56
Hence, X = (251.56/7.927)
= 31.73t

A ship of W 16000t, KM 7.5m, KG 6.0m , TPC 25, is listed 3 degree to port .Her present mean draft is 8.6m and she is to finish loading at 8.8m mean draft . Space is available 5m 0f the centre line, on either side. State how much cargo must be stowed on either side to finish upright
Solution :
W = 16000t,
KM, 7.5m KG = 6.0m,
Initial GM = 1.5 m
TPC = 25,
List = 3 degree P
Present draft = 8.6m
Final draft = 8.8
Sinkage available = (8.8 – 8.6)m
= 0.2m
= 20cm
Now , Cargo to load = (Sinkage x TPC)
= (20 x 25)
= 500 t
We know that :
LM =(W x GM tanθ)
Again , Initial LM = (16000 X 1.5 X Tan 3^{0})
= 1257.78 tm
Let ‘X’ t 0f cargo will load on port side
Cargo to be load on stbd side = (500 – X) t
So, final LM caused due to loading of cargo would be
LM(1) = (Weight x distance)
= (X x 5)
= 5X (P)
LM(2) = (Weight x distance)
= (500 –X) x 5
= (2500 – 5X ) (S)
As per above calculation ,
Initial LM = 1257.78 ( P)
Hence to keep vessel upright ,
LM(S) = LM(P)
(2500 – 5X) = (1257.7 + 5X)
2500 – 5X – 5X = 1257.7
( 10X) = (1257.7 – 2500)
X = (1242.3/10)
= 124 .3 t
Hence cargo loaded is 124.23 t on port side
So, cargo loaded in stbd is (500 – 124.23)
= 375.7 t

We know that:
Final KG = (Final VM/Final W)
= (67200/10000)
= 6.72m
Now, Final GM = (KM – KG)
=(7.3 – 6.72)m
= 0.58m
Again, tanθ = Final LM/ (W x GM)
= 162.56 /(10000 x 0.58)

A ship of W 13000t, KM 8.75m, KG 8.0m, has the list of 6degree to starboard . A heavylift weighing 150t lying on the upper deck 9m above the keel and 5m stbd of the centre line , is to be discharge using the ship’s jumbo derrick whose head is 22m above the keel . Calculate
 The list as soon as the load is taken by the derrick.
 When the load the hanging over the port side of the ship with an outreach of 10m from the centre line .
 After discharging the heavylift.
Solution:
Given :
Displacement (W) = 13000t,
KM = 8.75m &
KG = 8.0m
Initial GM =0.75m
List = 6 degree stbd ,
w = 150t,
KG = 9m lying = 5m to stbd ofC
derrick = 22m

We know that:
Final KG = (Final VM/Final W)
= (105950/13,000)
Final KG = 8.15m
Again we can calculate
Final GM = (KM KG)
= (8.75 – 8.15)
= 0.6m
Now, Tan =FLM /(W x GM)
= 1024.76/(13000 x 0.6 )
= 7degree 48minute (S)
Case – 2
When the load is hanging over the portside of the ship with on outreach of 10m from CL.
In this case the GM will be same but listing moment will change.
Listing moment caused =( W x d)
= (150 x 15)
= 2250 tm (P)
Hence, Final LM = (2250 – 1024.76)
= 1225.24 P
Tanθ = 1225.24/(13000 x 0.6)
= 8.9 degree P

We know that:
Final KG = (Final VM/ final W)
Final KG = (102650/12850)
Final KG = 7.988m
Now,Final GM =( KM – KG)
=(8.75 – 7.988)
= 0.762m
We know that :
Tanθ = FLM/( W x GM)

A ship of 10000t displacement is floating in SW and has KM of 10.8m and KG of 9.0m .she is listing 10degre to stbd. she has two rectangular deep tanks, one on either side , each 12m long ,12m wide and 9m deep . The stbd tank is full of FW while the port one is empty . If FW is to be transferred from the stbd tank to the port one , find
 The quantity of FW to transfer to bring the ship upright.
 The list if one third of the original FW in the stbd tank is transferred to the port tank.
NOTE : Fluid GM should be used here.
Solution :
Displacement(W) = 10000t,
KM = 10.8m, KG = 9.0M & GM = 1.8M
List = 10 degree stbd
Volume of tank = (L x B x H)
= (12 x 12 x 9 )m^{3 }
Initial LM = (W x GM x tan 10^{0} )
= (10000 x 1.8 x tan 10^{0})
= 3173.88tm
Case 1
To bring the ship upright the stbd LM must be equal to port side LM.
LM = (Weight x Distance)
3173.88 tm = ( W x 12)
Hence W = (3173.88/ 12)
= 264.49 t
Case 2
Volume of the tank = (L x B x D)
= (12 x 12 x 9)
= 1296m^{3}
Now, Weight of FW on stbd tank = (Volume x Density)
= (1296 x 1)
= 1296 t.
Now, calculating 1/3 of mass of FW
= (1296 x 1/3)
= 432t.

A ship has W 10000 t, KM 7.8m , KG 7.075m, and is upright . NO3 port and stbd DB tanks are full of HFO RD 0.95. Each tank is rectangular , 15m long ,12 wide and 2m deep . calculate the list when HFO is consumed from NO3 stbd until the sounding is 1.2m.
Solution :
W = 10000t,
KM = 7.8 ,
KG = 7.075,
GM = 7.8 – 7.075 = 0.725m ,
LM = 0
RD 0f HFO = 0.95
We know that, L x B x D = 15 x 12 x 2
Volume of stbd tank = 15 x 12 x 2

Wt of consumed HFO = 15 x 12 x 0.8 x 0.95

LM = W x D = ? doubt why ‘d’ taken as (6m)
FSC = LB cub x di / 12W

A ship of 14000t displacement , KM 9.0m , KG 7.8m has a total FSM of 2100tm and is listed 8degre to port . How many tonnes must be shifted transversely by 10m to upright the ship?
Solution :
W = 14000t ,
KM = 9.0m KG = 7.8m ,
Initial GM = 9 – 7.8 = 1.2
FSM = 2100 tm thit = 8degp,

To upright the vessel we have to shift ballast from to which is to the same LM of on stbd
We know that
