A Comparative Assessment of Simplified Models for Simulating Parametric Roll
(The American Society of Mechanical Engineers (ASME), 2017)The motion of a ship/offshore platform at sea is governed by a coupled set of nonlinear differential equations. In general, analytical solutions for such systems do not exist and recourse is taken to time-domain simulations ... -
A Comparative Overview of Marine Risers and Heat Exchanger Tube Banks
(The American Society of Mechanical Engineers (ASME), 1991)This is neither an original paper nor a review, but a comparative overview of two seemingly unrelated engineering fields. There are some similarities and strong dissimilarities between multipipe ... -
A Comparative Simulation Study of the Annual Maxima and the Peaks Over Threshold Methods
(The American Society of Mechanical Engineers (ASME), 2016)In order to assess their relative merits in the context of the determination of metocean extremes, the annual maxima (AM) and the peaks over threshold (POT) approaches are compared in terms of their accuracy in estimating ... -
A Comparative Study of Shutdown Procedures on the Dynamic Responses of Wind Turbines
(The American Society of Mechanical Engineers (ASME), 2015)The shutdown of wind turbines may induce excessive loads on the structures and is an important factor to consider in their design. For pitchregulated turbines, shutdown calls for blade pitching, and oneor twoblade shutdown ... -
A Comparative Study of Two Practical Methods for Estimating the Hydrodynamic Loads and Motions of a Semi-Submersible
