... Multi-layered flexible pipes have long been important components of PETROBRAS’ subsea production systems. Approximately 14,700 km of these pipes are in service throughout PETROBRAS’ assets in 2024, and more is planned to be laid down in the coming years. Flexible pipe design aims at complying...

... Abstract Failures in the annulus region of flexible pipes associated to corrosion related phenomena due to water ingress have posed significant challenges to the oil and gas industry, impacting reliability and operational safety of these equipment. Once the annulus flooding is one of the most...

...% of the failure incidents of flexible risers per industry reports ( MacLeod et al. 2023 ) and nearly all severe flexible pipe failures in the industry are related in some way to corrosion of the armor wires ( Muren et al. 2016 ). In order to assess the condition of armor wires suspected to be subjected...

... and corrosion. The project faced a number of challenges and unknowns regarding the decommissioning of a 20+ year-old subsea fields and floating facility, none more than the integrity of the FPSO and the flexible pipe system, particularly the dynamic risers. The riser system being terminated at the FPSO...

... Abstract The paper aims at presenting the extensive qualification approach adopted for the Hybrid Composite Flexible Pipe (HFP). The test results presented are mainly focused on the capacity of the PEEK-Carbon Fiber composite material and the pipe to resist to harsh environment, which combines...

... Abstract Flexible pipes tend to be complex structures, tailor-made, and require a significant amount of engineering in preparation for manufacturing and delivery. These features increase the cost and the time required between procurement and delivery, extending the project schedule...

... According to the Sureflex Report from 2023, the total length of flexible pipes ever supplied is reported as 18,580km. As of 2023, Petrobras had over 9,000 km of flexible pipes installed, over 5 000 km of these in Campos Basin. Most flexible pipes have been designed for a 20-30 year service life...

... Abstract The work presents an unprecedented standardization effort within the flexible pipe industry, that allows flexible pipe manufactures to still use their best design for each case while allowing the projects the flexibility to select pipes from a list of already qualified and ready...
