Q.2 A vessel of length 84m, displacement 3000t, TPC = 12t, KM = 4.5M, K.G. = 4.05m, MCTC = 80 mtm, CF 2m abaft of mid-ship at a draft of F 4m, A 4.5m is dry-docked. Calculate:i) The residual GM on taking blocks all over. ii) Her drafts F & A. Answer:
Q.2 A vessel of following particulars enters a SW dry dock. LBP = 140m, DF= 3.4m, DA = 5.8m, KG = 8.0, KM = 9.02, displacement = 8930t, TPC = 21.9t, LCF = 72.2m from AP, MCTC 162.5 tm. Find the virtual GM and draft F & A, when the level water has fallen one meter after stern has taken
Q.3 ‘M.V.Hindship’ displacement 8473 MT, KG: 8.84m, FSC: 0.146m, is to be Dry-docked. At the critical instant the GM (f) of the vessel is to be not less than 0.20m. Determine the maximum trim by stern with which she will enter Dry-dock if she is to take to the blocks first at the AP. Also state the arrival dry-dock drafts
Q.2 A ship of L = 200 m, W = 50000 T, MCTC = 250 T-m, KM 10 m, KG 5 m, TPC = 50 T, LCF 105 m, draft F 10.0 m, A 11.0 m, grounds lightly on an isolated rock in falling tide. At low water, the drafts are found to be F 9.5 m, A 11.0 m,
Q.2 A vessel of displacement 29000 t, LBP 185m, KM 11.50, KG 10.95. Draft Fwd 8.00m, Aft 9.38m, LCF 89.5m, MCTC 410 tm, TPC 29.5 t/cm. The depth of water in the dock is initially 10m. Find the effective GM and drafts Fwd and Aft after the water level has fallen by 1.35m. Answer: Q.3 M.V. Hindship, displacement 9348 T,
Q.3. M.V. Hindship displacement 12927 T, KG 7.850 m, FSM 1290 TM, is trimmed 0.70 m by the stern. She has to be dry-docked. Calculate:i) Virtual GM of the vessel when her keel takes the blocks all along the length of the vessel.ii) Drafts F and A when she sits overall on the blocks. Answer:
Q.1 M. V. Hindship displacing 9500 t and trimmed 0.80 m by stern is to be dry-docked for bottom inspection. KG = 7.92 m, FSM= 1600 tm. Calculate:a) The GM (F) of the vessel before entering the dry-dock.b) The virtual GM of the vessel when her heel taken blocks all along the length of the vessel. Answer:
Q.1) A v/l steering a westerly course observes Utklippan Lt. (55° 57’ N, 15° 41’E) at a bearing of 057°(T) and 8’ off. After running 16 miles by engines on her course Hano Lt. Gp fl 3 (56° 01’N, 14° 51’E) bore 328° (T) and after running another 8 by engines, it bore true north. Find: a) Vessel’s position at
Q.1) A vessel steering 084°C allowing for a current setting 234°T at 2.4knots observed Berry Head Lt. (50° 24’N 003° 29’W) bearing 348°C and Start Pt. Lt. (50° 13’N 003° 38’W) bearing 245°C. Find the vessel’s positions and estimate the relative bearing and distance off Bill of Portland Lt. (50° 30.8’N, 002° 27.4’W) on first sighting. Meteorological visibility is estimated
Q.1) At 1100 hours a vessel observes ‘Svartgrund’ buoy (55° 14.2’ N, 014° 15.2’E) 3 miles to NE with her engines under repairs. At 1300 hours the engines were started at a slow speed of 6 knots. Set course now to have ‘Hammerode’ Lt. Ho. (55° 17.9’ N, 014° 46.6’E) right ahead when 4 miles away. When will this light
