RISAn Analytical Treatment of Buckling and Instability of Tensile Armors in Flexible Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper addresses aspects related to local buckling and instability of tensile armors in flexible pipes. Analytical models for evaluating the tensile armor buckling capacity in both transverse (radial and lateral) ...
Analyzing the Sensitivity of Wave Frequency Responses of Floating Vessels to Uncertain System Variables Utilizing Polynomial Chaos Expansion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: From a mathematical viewpoint, the frequency domain analysis of vessel motion responses due to wave actions is based on integration of system dynamics idealized in terms of response amplitude operators for six degrees-of-freedom ...
Simulating High-Mode Vortex-Induced Vibration of a Riser in Linearly Sheared Current Using an Empirical Time-Domain Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As the development of offshore oil and gas continues to move into deeper waters, the risers connecting the seabed infrastructure to the offshore platform are getting longer. This means that vortex-induced vibration (VIV) ...
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 ...
