![]() Simulated tests have been carried out in simulated sea water, under conditions where the susceptibility is the highest, i.e. Hydrogen induced cracking (HIC) or hydrogen embrittlement (HE) of steel armour wires used in deep-water and ultra-deep-water has been evaluated. Įvaluation of Environmentally Assisted Cracking of Armour Wires in Flexible Pipes, Power Cables and UmbilicalsĮnvironmentally assisted cracking (EAC) of armour wires in flexible pipes, power cables and umbilicals is a major concern with the development of oil and gas fields and wind farms in harsh environments. The safe operating window for the installation is limited by whether induced motion of the installation vessel giving rise to dynamic tension and curvature at the touch-down-zone (TDZ). to a flow-line/sea floor installation or similar. ![]() Flexible pipes are mostly used to transport fluids between platforms/ships etc. Torsion instability of Flexible Pipes at the TDP - Torsjonsinstabilitet av fleksible rør med sjøbunnskontaktĭynamic flexible risers are a common term for cables, umbilicals and flexible pipes,that are freely or semi-freely suspended between two points (offshore). ![]()
