Q.1 A vessel of displacement 29,000 t, length 200m, Fwd draft 7m and Aft Draft 8.5m runs aground without any damage to her hull. Her MCTC 250 tm/cm and TPC 20 t/cm, LCF 105m, FSM 1000 tm, KM 8.5m, KG 7.8m. Tide then falls by 50 cm. The drafts then observed were to be Fwd 7.8m and Aft 7.5m. Calculate
Q.1 M.V. ‘Hindship’ displacement 16160 T, KG 7.850 m, FSM 2420 Tm to be dry docked. If on taking blocks overall the Residual GM (F) is to be 0.20m, determine maximum trim with which she will enter dry dock. Also state arrival drafts F & A. Answer:
Q.3 A vessel displacing 14000 tonnes enters dry-dock with a clearance of 0.50m over the blocks. Drafts while entering dry-dock are 5.35 forward, 6.77m aft, MCTC 120, TPC 22 tonne, LCF 4.00 m aft of mid-ships, length 150m, KG 6.25M, KM 6.40m. Assume the hydrostatic data to remain constant.Determine:a) The drop in water level required before the vessel takes the
Q.1 A ship of length 200m, Beam 32m, draft Fwd: 6.05m, Aft 6.75m is to be dry docked. CF = 3m aft of midship, MCTC 400 tm, KM = 8.45m, KG = 7.8m, TPC = 29t. Calculate her residual GM and drafts Fwd and Aft when the trim has reduced to 10 cms. Answer:
Q.2 A vessel of L = 150 m arrives dry-dock drawing 5.0 m forwards and 7.0 m aft. Her W = 12019 t, KG = 7.0 m, FSM = 800 tm, TPC = 22.47, MCTC = 174, LCB = 72.962 m, LCF = 72.476 m, KM = 8.438 m. If the declivity of the dock 20 cm per 100m, find
Q.2 A vessel of displacement 24000, LBP = 180, LCF = 20, TPC = 20, MCTC = 200 arrives in D.D. with drafts f = 8.20m, A=9.00m. Determine the residual GM when water level falls by 40cms after the stern touches the blocks. KG = 7.90m, KM = 8.30 m, FSM initial = 2000 Tm. Answer:
Q.2 A vessel of displacement 24000, LBP = 180, LCF = 94, TPC = 20, MCTC = 200 arrives in D.D. with drafts f =8.20m, A = 9.00m. Determine the residual GM when water level falls by 40 cms after the stern touches the blocks. KG = 7.90m, KM = 8.30m, FSM initial = 2000 Tm. Answer:
Q.2 A box-shaped vessel 150m long, 24m broad and 9m deep, has a mean draft in salt water of 6m and its trimmed 1m by the stern, KG 8.4m. State whether it is safe to drydock this vessel in this condition or not, and give reasons for your answer. Answer:
Q.2 A ship of L = 130 m, W = 5200 t, CF = 2m aft of midship MCTC = 140mt, KM = 6.5, K.G. = 6.0m, TPC = 20t, draft Fwd = 4.35m, Aft = 5.41m dry docked. Calculate her residual GM and the drafts F & A.i) When the trim reduced to 35 cms.ii) When the water level
Q.1 A vessel of length 141 mtrs, CoF = 2.6 mtrs, forward of midship, MCTC = 144, TPC = 19, KM = 7.7m, KG = 6.9m, w = 11300 T, at a dft F = 3.80m, A = 5.68m is floating in a dry dock where depth of water is 6.5m above the top of the blocks. Calculate vessels residual
