Murray's Method - Hogging SWBM
Still-water bending moment in hogging using Murray's method - the old-school hand-calc for bulk-carrier and tanker midship SWBM.
Buoyancy moment
9,520MN·m
Weight moment
840MN·m
Still-water BM
-8,679,840kN·m
Formula, assumptions, and limits
Hogging is positive SWBM; sagging is negative. Compare against rule allowable and against wave bending moment via IACS UR S11.
