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
