abstract

Focusing on the integrity of umbilical cable components during the laying operation, particularly on hoses integrity, this paper assesses displacement fields on umbilical cable cross-sections by means of a special crushing test setup. Using a high resolution Digital Image Correlation system (DIC), experiments with two umbilical cables are carried out in a 250 kN mechanical tests rig. Besides measuring the components displacements, applied crushing forces and shoes displacements are acquired. The experimental samples are taken from two HCR-hoses umbilical cables, which have been cases of study of a finite element analysis methodology, recently proposed and presented in OMAE2015, [12]. Experimental analysis and a theoretical-experimental correlation are presented, for both umbilical cables.
