Figure B-3. Stresses due to an immediate stop of pipe suspension medium 

 (60CHon load). 



Stresses Due to Ship Motions. It is of great importance to investigate 

 the pipe and load dynamics and the maximum dynamic stress in the pipe 

 resulting in the motions of the suspension point. These factors can be 

 utilized in a design procedure for calculating dynamic stresses for a given 

 load at a given depth under varying conditions of sea surface oscillations.
