Offshore riser damage-resistant design by state-of-the-art multidimensional reliability concept and generalized 4-parameter Weibull estimator

Energy transportation systems are becoming economically viable as marine and offshore technologies, including both renewable and hydrocarbon energy-generating sources, advance, thereby diversifying the energy mix. Marine risers, umbilicals, and other flexible pipelines are employed by deep-sea mining, offshore wind far...

Fading-Induced Phase-Fluctuation Reduction and SNR Enhancement in ϕ-OTDR Using Video Block-Matching 3-D Collaborative Processing

Coherent fading and random background noise are two major factors that degrade phase stability and weak-vibration detection in distributed acoustic sensing (DAS) systems. Coherent fading induces local amplitude fading and phase-demodulation instability, whereas random background noise obscures vibration responses and l...

Overcoming Label Scarcity in Distributed Acoustic Sensing via Masked Spectrogram Modeling

Distributed acoustic sensing (DAS) enables continuous monitoring of large-scale infrastructure, but the deployment of robust intelligent systems is severely hindered by the scarcity of expertly annotated data, cross-environmental domain shifts, and spatial biases caused by irregular physical fiber geometries. To addres...
