RISResponses of Articulated Loading Platform in Irregular Waves
Publisher: American Society of Civil Engineers
Abstract: The wave frequency and slowly varying responses of an articulated loading platform (ALP) in unidirectional irregular waves are investigated both in frequency and time domain. The first- and second-order wave diffraction/radiation ...
Second-Order Low-Frequency Wave Forces on a SPM Offloading Tanker in Shallow Water
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies the influence of three different calculation methods of the second-order low-frequency (LF) wave-force quadratic transfer functions (QTFs) for a single point mooring (SPM) tanker ...
Coupled Dynamic Analysis of a Moored Spar in Random Waves and Currents (Time-Domain Versus Frequency-Domain Analysis)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonlinear coupled responses of a moored spar in random waves with and without colinear currents are investigated in both time and frequency domains. The first and second-order wave forces, added ...
The Effects of Inner-Liquid Motion on LNG Vessel Responses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The coupling and interactions between ship motion and inner-tank sloshing are investigated by a potential-viscous hybrid method in the time domain. For the time-domain simulation of vessel motion, ...
Linear and Nonlinear Approach of Hydropneumatic Tensioner Modeling for Spar Global Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with a numerical model of top tension risers with hydropneumatic tensioner for Spar application in the Gulf of Mexico environment. The nonlinearity of the stiffness and the ...
Flexible Membrane Wave Barrier. II: Floating/Submerged Buoy-Membrane System
