... focused on considering the effects of corrosion degradation in time. The fatigue limit state and the corrosion allowance of mooring chains are safety requirements that need to be verified continuously through mandatory regular inspections. The present work proposes a new efficient reliability-based method...

... Abstract Coal Tar coatings were extensively utilized from the 1960s to around 1990 to waterproof offshore oil facilities, such as pipelines, and shield them from corrosion. However, in the 2000s, Coal Tar was found to be linked with a significant release of polycyclic aromatic hydrocarbons...

... equipped with cameras offer a promising solution for efficient data collection. This research addresses the need for automated corrosion detection and classification in images captured by UAVs, revolutionizing asset maintenance practices. Despite advances in computer vision and deep learning...

... pressure was compared with experimental results from literature with an error of 3%. The numerical-experimental correlation validated the numerical model, which can be used with reliability and safety by industry. corrosion pipeline repair composite material Proceedings of the ASME 2024 43rd...

... their durability vital against extreme weather conditions. While direct monitoring of these lines would be preferable, it is often unpractical due to high costs and maintenance. This research presents a new method to evaluate the degradation of mooring lines. The study investigates fatigue and corrosion behavior...

... Abstract Well integrity management is essential for preventing well leakage and ensuring the optimal performance of oil and gas wells. Existing downhole monitoring tools are complex to install and unable to monitor the corrosion condition along the wellbore. These drawbacks limit the effective...

... Abstract Internal corrosion of steel pipelines before use, or temporarily taken out of use, and ‘parked’ on the seafloor for some time (months), suspended from operation or ‘abandoned’ for extensive period of time continues to be an issue for offshore operators and regulators...

... Abstract The present study investigates the effects of pitting corrosion and welding, both independently and combined, on the buckling and post-buckling behaviour of extruded aluminium panels. For this purpose, a finite element model of an aluminium panel made of AA6082-T6 extruded profiles...

... Abstract In this study, we focused on the corrosive wear, assuming that the frequent removal of rust layers by sea ice friction may accelerate corrosion. We performed simple experiments on repeated removal of rust layers on a metal material surface by an artificial method to simulate the rust...

... been reported in the literature. Most of these were related to fatigue and corrosion degradation in the top chain links, becoming a major concern. Since then, a great effort has been made to improve fatigue assessment methodologies of these elements and to model the effects that are not properly...

... levels and load ranges and provide a unique opportunity to study how the fatigue strength is influenced by mean load and degree of corrosion. Considerations have also been made to obtain consistency in the test results for tests with different number of links in the test sample. The main result from...

... Abstract Nickel Aluminium Bronze (NAB) continues to be used extensively in the marine industry and is most commonly seen in valves and propellers due to its strength and corrosion resistance. However, components used for marine applications often endure long exposure to air during storage...

... Abstract Pipelines are one of the most economical and safe means of transporting useful materials, and their design life depends on protection mechanisms present. Marine environments increase corrosion rates due to moisture, and elements like chloride which increase localized pitting rates...

... are related to fatigue damage in the chain links of the top or bottom segments. Material degradation due to corrosion effects plays an important role in this failure mechanism. Engineering practice usually recommends that a constant corrosion rate model is to be adopted in the design. Periodic inspections...

... Abstract We report on a multi-year investigation into mechanisms of fatigue, corrosion, and abrasion on floating offshore wind turbine (FOWT) mooring systems funded by the U.S. Bureau of Safety and Environmental Enforcement (BSEE). The project team examined the efficacy of standards-based...

Therefore, to ensure the operational safety, their design should consider the combined action of fatigue and corrosion phenomena...

... When risers are designed it is common for corrosion to be accounted for by including a corrosion allowance in the wall thickness [3]. However, when designing risers which are subject to fatigue loading from various sources, simply allowing extra thickness in the wall is inadequate to protect...
