RISImproved In-Line Vortex-Induced Vibrations Prediction for Combined In-Line and Cross-Flow Vortex-Induced Vibrations Responses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Slender marine structures are subjected to ocean currents, which can cause vortex-induced vibrations (VIV). Accumulated damage due to VIV can shorten the fatigue life of marine structures, so it needs to be considered in ...
Prediction of Combined Inline and Crossflow Vortex-Induced Vibrations Response of Deepwater Risers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Deepwater risers are susceptible to vortex-induced vibrations (VIV) when subjected to currents. When responding at high modes, fatigue damage in the inline (IL) direction may become equally important as the crossflow (CF) ...
Wave Effects on Vortex-Induced Vibrations of a Top-Tensioned Riser
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Offshore drilling risers and many production risers are top-tensioned risers (TTRs), connecting the vessel and seabed via joints. External loads such as currents, waves, and vessel motions introduce cyclic loads and motions ...
Forced Vibration Tests for In-Line Vortex-Induced Vibration to Assess Partially Strake-Covered Pipeline Spans
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Helical strakes can suppress vortex-induced vibrations (VIVs) in pipelines spans and risers. Pure in-line (IL) VIV is more of a concern for pipelines than for risers. To make it possible to assess the effectiveness of ...
