摘要

Oceans cover 70% of the Earth's surface and play a vital part in influencing the climate of the earth. Oceanography is essential for predicting and forecasting weather. Various ocean observation technologies and systems are available, including moored surface buoys, which are used to monitor weather. The surface buoy system consists of over 100 components that are deployed in coastal and deep seas to collect meteorological and ocean parameters. In this study, a failure analysis was performed on one of the mooring components known as the connecting ring, which was used for retrieval operations. Several tests are conducted in this study to determine the underlying cause of the failed connecting ring (FCR), including chemical analysis, stereo zoom microscope, energy-dispersive X-ray spectroscopy hardness, and microstructure analysis.
