Abstract. Numerical experiments on mechanics of the curved tubing with the profile in the form of the catenary are carried out. It is found out that the constructed mathematical model adequately describes selected well-known phenomena observed in dynamics of marine risers. The paper also identifies limitations of the range of applicability of the mathematical model. The author predicts in theory the existence of warpings of cross-sections of tubings of the class under study, as well as the presence of tubing sections with finite wall deformations.
