Optimization of Cathodic Protection on Offshore Structures
Marine structures are one of the most important and susceptible facilities in Iran due to corrosion. The two methods of Cathodic Protection, namely, the cathodic protection with sacrificial anodes and cathodic protection using impressed current, are widely used for corrosion protection. According to the former, sacrificial anodes are installed at several points in the structure. Position of the...

متن کاملSafety of Offshore Structures
This lecture presents an overview of important developments regarding the safety management of offshore structures. The hazards and the means to control the associated risk are categorized from a technical-physical as well as human and organizational point of view using actual accidents and near misses as examples. Considerations of the risk associated with fatigue, corrosion and other degradin...
متن کاملExperimental Study on Strength and Ductility of Underwater Fillet Welds in Repairing Offshore Steel Structures
Underwater wet welding is one of the most common repair measures for corroded offshore steel structures. Few studies have been carried out systematically concerned with mechanical properties of such welds, thus current design provisions rely heavily on limited experimental data on welds made underwater and design properties for corresponding welds made in air. This paper presents a series of ex...
متن کاملUnderwater noise from offshore oil production vessels.
Underwater acoustic recordings of six Floating Production Storage and Offloading (FPSO) vessels moored off Western Australia are presented. Monopole source spectra were computed for use in environmental impact assessments of underwater noise. Given that operations on the FPSOs varied over the period of recording, and were sometimes unknown, the authors present a statistical approach to noise le...
