Finite element investigation on the tensile armor wire response of flexible pipe for axisymmetric loading conditions using an implicit solver
Composite flexible pipe is used in the offshore oil and gas industry for the transport of hydrocarbons, jumpers connecting subsea infrastructure, and risers with surface platforms and facilities. Although the material fabrication costs are high, there are technical advantages with respect to install...
