RISScour Around Vertical Pile Foundations for Offshore Wind Turbines Due to Long Crested and Short Crested Nonlinear Random Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper provides a practical stochastic method by which the maximum equilibrium scour depth around vertical piles exposed to longcrested (2D) and shortcrested (3D) nonlinear random waves can be derived. The approach is ...
Damping Effect on the Wave Propagation in Carbon Steel Pipelines Under Fluid Hammer Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A sudden reduction of the fluid flow yields a pressure shock, which travels along the pipeline with a high-speed. Due to this transient loading, dynamic hoop stresses are developed that may cause catastrophic damages in ...
Numerical Simulations of Breaking Waves and Steep Waves Past a Vertical Cylinder at Different Keulegan–Carpenter Numbers
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: A three-dimensional (3D) numerical two-phase flow model based on solving unsteady Reynolds-averaged Navier–Stokes (URANS) equations has been used to simulate breaking waves and steep waves past a vertical cylinder on a ...
Numerical Study of a Single-Point Mooring Gravity Fish Cage With Different Deformation-Suppression Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compared with the multipoint mooring fish cage, the single-point mooring (SPM) fish cage can spread out the fish wastes and uneaten feeds in a larger area, and it can also prevent the local environment from being overwhelmed. ...
Numerical Investigations on Suspended Power Cable Configurations for Floating Offshore Wind Turbines in Deep Water Powering an FPSO
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Floating offshore wind turbines (FOWTs) are an opportunity for floating production storage and offloading units (FPSOs) to reduce emissions. To avoid long connecting power cables with long transmission distances between a ...
Power Performance and Response Analysis of a Semi-Submersible Wind Turbine Combined With Flap-Type and Torus Wave Energy Converters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An integrated offshore wind and wave energy system is an attractive concept in areas with abundant wind and wave energy resources. The sharing of supporting platform and facilities, e.g., mooring systems, offers significant ...
Modal Analysis of Wake Behind Stationary and Vibrating Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic mode decomposition (DMD) and proper orthogonal decomposition (POD) are used to analyze the coherent structures of turbulent flow around vibrating isolated and piggyback cylinders configurations subjected to a ...
Design Considerations of a Subsea Shuttle Tanker System for Liquid Carbon Dioxide Transportation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Subsea pipelines and umbilicals are used for the transportation of fluids and electrical power between subsea installations and floating production units (FPUs). The installation and maintenance of these systems can be ...
Numerical Simulations of Turbulent Flow Through an Orifice Plate in a Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Orifice flowmeters are widely used in industries to measure the flowrate in pipelines. The flowrate inside the pipe can be calculated using the relationship between the flow velocity and the pressure drop across the orifice ...
Prediction for Global Whipping Responses of a Large Cruise Ship Under Unprecedented Sea Conditions Using an LSTM-Based Encoder–Decoder Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Global whipping responses contribute to a significant increase in vertical bending moments (VBM), making their accurate prediction crucial for ship safety. In this study, a long short-term memory (LSTM)-based encoder–decoder ...
