To investigate the effects of breathing cracks on dynamic characteristics, i.e., natural frequencies, vibration displacement, slope angle, and bending moment, a drilling riser, time-domain finite element method based fracture mechanics theory is developed. The correctness proposed verified, performance different characteristics for crack identification evaluated. First, influence open frequencies explored. maximum frequency shifts vs location water depth are studied. results small difference...
Deepwater subsea wellheads may be significantly threatened under extreme sea conditions and operations, especially when the seabed is composed of very soft clay properties. A numerical model a deepwater wellhead system established using classic ocean pipe element nonlinear spring ANSYS to examine behaviors in diverse soil. Nonlinear elements coded APDL language are used three types soils: soil, firm The dynamic quasi-static typical coupled decoupled models drilling riser particularly...
Deep-sea mining risers emerge as the most fragile and technologically demanding segment of entire operation system. It is essential to thoroughly investigate risers' dynamic responses fatigue distributions explain motion mechanism. This paper employs time-domain finite element method examine vibration behaviors a deep-sea riser across variety sea conditions. The accuracy developed model verified by different numerical methods results in literature. characteristics are correspondingly...
To analyze the dynamic response of a rigid M-shaped jumper subjected to combined internal and external flows, one-way coupled fluid–structure interaction process is applied. First, CFD simulations are conducted separately for fluid domains. The pressure histories on inner outer walls exported loaded into finite element model using inverse distance interpolation. Then, FEA performed determine response, followed by fatigue assessment based obtained stress data. displacement, acceleration,...
Abstract To prevent marine risers' resonance and eliminate potential threats, sufficient inherent dynamic characteristics such as natural frequency, modal displacement, slope, bending moment, shear are necessary to be calculated analyzed. However, most studies calculate the frequencies displacements directly rather than slopes forces. The additional calculations of forces likely result in issue complications, time-consuming, or even errors especially when boundaries at both ends solved by a...
