Estimation of Hydrodynamic Forces on Cylinders Undergoing Flow-Induced Vibrations Based on Modal Analysis
(Peer reviewed; Journal article, 2022)The objective of the present study is estimating hydrodynamic forces acting on cylinders undergoing vortex-induced vibration (VIV) using dynamic mode decomposition (DMD). The cylinders are subjected to a uniform incoming ... -
Linear quadratic regulator optimal control of two-rotor wind turbine mounted on spar-type floating platform
(Peer reviewed; Journal article, 2022)Interest is steadily growing for multi-rotor wind turbine concepts. This type of wind turbine offers a practical solution for scaling issues of large wind turbine components and for the reduction of costs associated with ... -
Modal analysis of offshore monopile wind turbine: An analytical solution
(Peer reviewed; Journal article, 2022)An analytical solution of the dynamic response of offshore wind turbines under wave load with nonlinear Stokes’s wave theory and wave–structure and soil–foundation interactions is developed. Natural frequencies and the ... -
Numerical analysis of a vessel-shaped offshore fish farm
(Peer reviewed; Journal article, 2018)The aquaculture industry is aiming to move fish farms from nearshore areas to open seas because of many attractive advantages in the open water. However, one major challenge is to design the structure to withstand the ... -
Three-dimensional Large Eddy Simulations and Proper Orthogonal Decomposition Analysis of Flow around a Flexibly Supported Circular Cylinder
(Peer reviewed; Journal article, 2022)Three-dimensional (3D) numerical simulations of the flow around a cylinder undergoing vortex-induced vibration (VIV) at Re = 3900 (defined as Re = U infinity D/nu, where U-infinity is the inlet flow velocity, D is the ... -
Trajectory Envelope of a Subsea Shuttle Tanker Hovering in Stochastic Ocean Current - Model Development and Tuning
(Peer reviewed; Journal article, 2022)A subsea shuttle tanker (SST) concept for liquid carbon dioxide transportation was recently proposed to support studies evaluating the ultra-efficient underwater cargo submarine concept. One important topic is the position ... -
UiS Subsea-Freight Glider: A large buoyancy-driven autonomous cargo glider
(Peer reviewed; Journal article, 2022)This study presents the baseline design for the autonomous subsea vehicle capable of traveling at a lower speed of 1 m/s with an operating range of 400 km. Owing to UiS subsea-freight glider’s (USFG) exceedingly economical ...
