Multiaxial Fatigue Analysis on Reeled Steel Tube Umbilical
Multiaxial fatigue analysis on reeled steel tube umbilical is proposed based on finite element analysis (FEA) results. Due to the complexity of the umbilical geometry, stresses and strains field becomes multiaxial, worsening the fatigue resistance. Reel-lay method, is one of the most efficient and c...
