A barge is completely wall-sided, 100 m long, 20 m maximum beam and it floats at a draught of 6 m in still water. The barge waterlines are parabolic and symmetrical about amidships with zero ordinates at the ends. The weight is evenly distributed along its length. If the vessel is 15 m deep, has a sectional second moment of area 30 m² and has a neutral axis 6 m from the keel, find the maximum hogging stress when balanced on an L/20 trochoid wave.

Answer rating: 100% (QA)

To find the maximum hogging stress on the barge we need to consider the bending moment caused by the L20 trochoid wave and the section modulus of the barge The section modulus of the barge is given by ... View the full answer
