Q.1 M. V. Hindship sailed from port in condition No. 8 soon after departure she grounded on an isolated rock, without damage to her hull. The drafts then were observed to be F 5.90m, A 9.30m. Calculate the following:i) The upthrust provided by the rockii) The position with respect to AP, where the grounding occurred. Answer:
Q.1 M. V. Hindship sailed from port from drafts F 8.800 m and A 9.200 m resp. with KG 7.850 m and FSM 1950 TM. On her voyage she grounded on an isolated rock, without damage to her hull. The drafts then were observed to be F 8.300 m and A 9.300 m. Determinei) The position w.r.t. AP where the
Q.2 A ship of L = 140m, COF = 2m, FWD of M/Ship, KM = 6.1 m, KG = 5.5 m, MCTC = 130 tm, TPC = 16, W = 5700T, at Drafts F/4.15 m, A/4.85 m, grounds on a rock. 10 abaft her stem. The tide then falls by 0.80 m. Calculate her V GM then and her final
Q.1 A vessel floating at drafts forward 8.0 m aft 9.0 m, grounds at a point 25 m aft of forward perpendicular. Calculate the drafts and virtual GM of the ship when the tide has fallen by 75 cm. Given MCTC 300 tm, TPC 30 t, KG 7.5 m, KM 8.5 m, Length 165 m, LCF 80 m, forward of
Q.2 A vessel of L = 140 mt, W = 16000t, MCTC = 190, TPC = 24t, LCF = 72m, KM = 8.20m, KG = 7.20m, FSM = 1370mt, draft = Fwd = 6.68m, Aft = 8.84m grounds on an isolated rock, the draft then are fwd 5.88 and aft 9.28m. Calculate following:i) The up thrust provided by the rock.ii)
Q.2 A ship of L = 150m drawing 5.0m forward and 7.0m aft. Her W = 13,000 t, TPC = 23, LCF = 73.50 m runs aground at a point 20m aft of forward perpendicular. After grounding the drafts are found to be 4.6m forward and 7.0 aft. Find:(a) Rise in tide required for the vessel to refloat. (b) Upthrust
Q.2 A vessel of L 148 m, LCF 70 m, draft forward 8.00 m, draft aft 9.80 m, TPC 32, MCTC 264 lightly grounds on gently sloping seabed. Soundings taken in that instant showed forward depth as 8.00 m and aft depth as 10.9 m. Find the draft after tide falls by (a) 30 cm (b) 2.00 m Answer:
Q.2 A ship of L = 140m, W = 16000t, LCF=72m, MCTC=190tm, FSM=137tm, KM = 8.2m, KG = 7.2m TPC=24t, draft Fwd = 6.70m. Aft = 8.85m grounds lightly on an isolated rock. The drafts now are found to be fwd 5.90m and aft 9.30m. Calculate the virtual GM and the rise of tide required to refloat the vessel. Answer:
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:
