A two-dimensional finite-element computational method is presented for determining marine riser displacements and stresses due to self-weight, buoyancy, internal and external pressures, surface vessel motions and environmental forces arising from currents and waves. A dynamic analysis is performed in the...
The study focuses specifically on the effect of the inner flow to the global dynamics of the riser. This task is accomplished using time domain teachings and the Finite Element method is used as a powerful numerical method. Moreover the Euler-Bernoulli beam theory is used response to model ...

This paper proposes a numerical simulation method for the dynamic motion of a flexible riser pipe undergoing vortex-induced vibration (VIV). The method is based on a finite difference scheme for solving nonlinear structural dynamics of the pipe and wake oscillator model for quantifying vortex-induced...
Axial hydrodynamic loads on a riser system are often ignored in traditional analysis methods. To accurately analyze the axial dynamic response of risers, an improved axial dynamic analysis method of risers is proposed based on finite element method and data-driven models. Finite element method is ...
Riser analysisFinite Element MethodStructural AnalysisA comparison of 4 types of finite elements for vibration analysis of plane marine risers undergoing small displacements has been made. The elements were 3 elements without bending stiffness and having 2, 3 or 4 displacements, and a modified 2-...
Both the method of engineering and nonlinear finite element method have been used to the analysis and optimum design of the 30 in. marine riser with the screw thread. Two load steps have been used in the finite element analysis including the processes of both assembling and applying the load ...
A three-dimensional finite element analysis was performed to obtain a detail residual stress distribution of a ceramics/metal joint. A peak tensile stress occured near the interface in a ceramic side and showed a maximum value on edges. Several types of two-dimensional analyses, i. e. plane st...
A digital twin (DT) method is proposed to estimate the dynamic and structural behaviors of a Steel Lazy Wave Riser (SLWR) under environmental conditions. This method uses a 1D finite element (FE) riser model that can include various loads and boundary conditions measured from sensors. We selec...
