TL;DR: In this article, the reliability of pipelines with corrosion defects subjected to internal pressure using the first-order reliability method (FORM) is defined based on the results of a series of small-scale experiments and three-dimensional nonlinear finite element analysis of the burst pressure of intact and corroded pipelines.

TL;DR: In this paper, the effect of external corrosion defects was studied via a series of small-scale experiments and through a nonlinear numerical model based on the finite element method, which was used to determine the burst pressure as a function of material and geometric parameters of different pipes and defects.

TL;DR: A literature review on failure events experienced by the industry concerning pipelines, risers, and umbilical cables, describing their causes, consequences, and severity is presented in this article, where the main failure modes reported are due to mechanical damage, corrosion, construction defect, natural hazards and fatigue.

TL;DR: In this paper, a sequentially coupled thermo-mechanical finite element model that considers temperature-dependent material properties, high temperature effects and a moving volumetric heat source was used to investigate the effect of welding sequence on the residual stresses and distortions in T-joint welds.

TL;DR: In this paper, a methodology for the geometrical optimization of wave energy converters (WEC) based on statistical analysis methods and the hydrodynamics of the system in the frequency domain is presented.
