30 MCQs #1 The KG of a vessel is found by dividing the displacement into the __________. #2 If the result of loading a vessel is an increase in the height of the center of gravity, there will always be an increase in the __________. #3 The important stability parameter, KG, is defined as the __________. #4 A vessel's KG is determined by __________. #5 A partially full tank causes a virtual rise in the height of the __________. #6 Which technique could be used to give a more comfortable roll to a stiff vessel? #7 What will NOT decrease the stability of a vessel? #8 A virtual rise in the center of gravity may be caused by __________. #9 In illustration D001SA below, which item represents the righting arm? #10 If the cause of a sudden severe list or trim is negative initial stability, counterflooding into empty tanks may __________. #11 A ship's forward draft is 22'-04" and its after draft is 24'-00". The draft amidships is 23'-04". This indicates a concentration of weight __________. #12 You are loading in a port subject to the winter load line mark and bound for a port subject to the tropical load line mark. You will enter the summer zone after steaming four days, and you will enter the tropical zone after a total of twelve days. You will consume 31 tons of fuel, water, and stores per day. The hydrometer reading at the loading pier is 1.000, and the average TPI is 46. What is the minimum freeboard required at the start of the voyage? Reference Table BL-0013 below. #13 In order to calculate the TPI of a vessel, for any given draft, it is necessary to divide the area of the waterplane by __________. #14 A vessel is limited to a maximum draft of 26'-03". The present drafts are: FWD 21'- 04", AFT 24'-06". How much more cargo can be loaded and where should it be located if a drag of 1 foot is desired? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book) #15 A vessel is limited to a maximum draft of 25'-11". The present drafts are: FWD 24'- 10", AFT 23'-02". How much more cargo can be loaded and where should it be located if a drag of 18 inches is desired? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book) #16 Your vessel's draft is 24'-06" forward and aft. The MT1 of your vessel is 1000 ft- tons. How many tons of cargo must be loaded in number 4 hold, which is 100 feet abaft the tipping center, if she is to have a 2 foot drag? #17 The SS AMERICAN MARINER arrived in port with drafts of: FWD 28'-04", AFT 29'- 10". Cargo was loaded and discharged as indicated in table ST-0102 below. Use sheet 2 in the white pages of the Stability Data Reference Book to determine the final drafts. #18 You have 38 containers of ships stores each measuring 6'L by 6'B by 5'H and weighing 0.6 ton each. Each container is stowed on deck. What is the maximum VCG permitted of the remaining cargo if you are carrying rig water and load to maximum capacity? See illustration D037DG below. #19 You have 50 containers of ships stores each measuring 6'L by 4'B by 3'H and weighing 0.4 ton each. Each container is stowed on deck. What is the maximum VCG permitted of the remaining cargo if you are carrying rig water and load to maximum capacity? See illustration D037DG below. #20 You have 6 containers of ship stores each measuring 8'L by 4'B by 6'H and weighing 0.5 ton each. Each container is stowed on deck. What is the maximum VCG permitted of the remaining cargo if you are carrying rig water and load to maximum capacity? See illustration D037DG below. #21 The SS AMERICAN MARINER is ready to bunker with drafts of FWD 13'-10", AFT 16'-04". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0187 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction. #22 The SS AMERICAN MARINER is ready to bunker with drafts of FWD 11'-01", AFT 15'-01". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0091 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction. #23 The SS AMERICAN MARINER is ready to bunker with drafts of FWD 18'-06", AFT 20'-06". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0099 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction. #24 The SS AMERICAN MARINER is ready to bunker with drafts of FWD 11'-01", AFT 15'-01". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0103 below.
