.... The assessment in both locations is performed for two structural models: an idealized stress spectrum for a generic fatigue hot-spot and a steel lazy wave riser (SLWR) connected to a floating production storage and offloading (FPSO). Fatigue life is estimated using the S–N curve approach. Results show...

...Elvis Jhoarsy Osorio Santander; Bianca de Carvalho Pinheiro; Carlos Magluta; Ney Roitman In the development of oil and gas fields, subsea pipes are used in various applications, like pipelines and risers. During operation, risers can be subjected to accidents, such as collisions with other risers...
