Review Question For Chief Officers

Dear Candidates

Good Time

Kindly solve following question and present your answer in first session after new year holidays

A vessel of length 90 m has equally spaced half ordinates of the waterplane as follows, commencing from the after perpendicular 

Station                                       0                   1                  2                  3                  4                  5                  6

Ordinate (m)                        0.1               2.4                2.7               2.8                2.8               2.2               0.2

 

Find the

 

 

Find the Area of the Waterplane

----------------------

A vessel of length      300 m has half ordinates of waterplane as follows, commencing from the after perpendicular

Station                                         0             ½             1             2              3             4            5            5 ½          6

½ Ordinate (m)                          0.1          7.5           10            12          12.3        11.4          8           5.2          1.0

Find the area of the waterplane if there are appendages forward and aft with a total area of 2.8 m2 to be added to the main area

 

----------------------

A vessel of length 240 m has the ½ ordinates of water plane area shown, spaced at equal intervals; commencing from the AP

Station                0            1              2               3               4               5               6             7           8

1/2Ord (m)         0         12.0          14.5          15.0          15.0          14.0          12.0        8.0         3.5

 The vessel has a draft of 20 m and the block coefficient at this draught is 0.79 m. Calculate the TPC in salt water and the Fresh Water Allowance at this draft

 

-----------------------------

A vessel has the following dimensions: Length 120.0 m; block coefficient, 0.78; KB 3.2 m; ½ ordinates of the waterplane at the 6.0 m draft are

Station                           0            1              2               3               4             5            6

 1/2Ord (m)                 0         14.0          15.0          15.0          15.0         9.5         1.0

If the vessel is floating on an even keel at a draft of 6.0 m, calculate the vessel's KM

--------------------------------------------

 

An undivided double bottom tank with vertical sides of depth 1.5 m has ½ ordinates commencing at the after bulkhead as follows

Station                            0            1           2            3           4            5           6

  1/2Ord (m)                     6.0        6.0         5.9        5.7         5.4         4.9        4.3

The after bulkhead is 65 m forward of the after perpendicular. Find the volume of the tank, the distance of the centroid of the tank from the AP and the free surface moment-of the tank when it contains fresh water

-----------

A box shaped vessel has a length of 100 m, breadth of 10 m and draft of 4 m in water of density 1.010 tonnes/m3. Find

a)  Her present displacement

b) Her new draft if she loads 750 tonnes of cargo in this density of water

(c)  Her new draft if she  then proceeds to sea (density 1.025

(d)  Her new draft on arrival at a port where the water density is 1.005 tonnes/m3 (cargo still on board

e)  How much cargo has been discharged at that port if after discharging the draft is found to be 3.5 m
