Shells Shipping saddles

The stresses in the vessel shell should be determined by standard Zick s analysis. The location of shipping saddles should be determined such that the bending at the midspan and saddles is not excessive. Also, the stresses due to bending at the horn of the saddle is critical. If this stress is exceeded, the saddle angle and width of saddle should be increased. Also, move the saddle closer to the head or a major stiffening element. 

For vessels that recjuire pivot bolsters, the shipping saddles shall be adecjuately braced by diagonal ten-sion/compression rods between the vessel and the saddle. The rods and clips attached to the vessel shell should be designed by the s essel fabricator to suit the specific recpiirements of the carrier.
