Parametric Study of SCFs in Unstiffened Gap Tubular KT-joints of Offshore Structures under OPB Moment Loading
In this paper, results extracted from a set of stress analyses performed on 46 FE models for unstiffened gap tubular KT-joints are presented and discussed. The main objective of the FE analyses, validated against experimental data, was to run a parametric investigation on the effects of geometrical characteristics of the joint on the values of the stress concentration factors (SCFs). The SCF is...
متن کاملExperimental and Numerical Investigation of Geometric SCFs in Internally Ring-Stiffened Tubular KT-Joints of Offshore Structures
Tubular KT-joints are quite common in offshore structural design and despite the crucial role of stress concentration factors (SCFs) in evaluating the fatigue performance of tubular joints. However, the SCF distribution in internally ring-stiffened KT-joints have not been investigated and no design equation is currently available to determine the SCFs for this type of joint. In the present pape...
متن کاملDegree of Bending in Axially Loaded Tubular KT-Joints of Offshore Structures: Parametric Study and Formulation
The fatigue life of tubular joints commonly found in offshore industry is not only dependent on the value of hot-spot stress (HSS), but is also significantly influenced by the through-thethickness stress distribution characterized by the degree of bending (DoB). The determination of DoB values in a tubular joint is essential for improving the accuracy of fatigue life estimation using the stress...

متن کاملOptimization of Cathodic Protection on Offshore Structures
Marine structures are one of the most important and susceptible facilities in Iran due to corrosion. The two methods of Cathodic Protection, namely, the cathodic protection with sacrificial anodes and cathodic protection using impressed current, are widely used for corrosion protection. According to the former, sacrificial anodes are installed at several points in the structure. Position of the...
