Zhi, Yuanzhe (2018-04-16)An extended least square method for reflection analysis that separates long-crested or short-crested wave fields into the incident and reflected components from the measured wave surface elevations and from other wave ...
-
Young, Dustin Ray (2010-07-14)Dredge cutting forces produced by the movement of the cutterhead through the sediment have been measured with the laboratory dredge carriage located at the Haynes Coastal Engineering Laboratory. The sediment bed that was ...

Ryu, Sangsoo (Texas A&M University, 2005-02-17)To reduce large motion responses of moored platforms in a harsh environment in deep waters, a thruster-assisted position mooring system can be applied. By applying the system, global dynamic responses can be improved in ...
-
Kang, Heonyong (2014-09-05)Two main topics of offshore technologies, hydroelasticity and dynamic positioning system, are investigated in the present research. For the larger dimension of offshore structures in harsher operating environments, ...
-
Lee, Chi Hun (2011-08-08)Salinity is a major determinant of where and how water resources are used worldwide. Natural salt pollution severely constrains the beneficial use of large amounts of water in Texas and neighboring states. High salinity ...

Choi, Hae-Jin (Texas A&M University, 2007-04-25)A comprehensive experimental study was conducted to produce benchmark wave kinematics data for five different regular waves and the maxima of four different irregular wave trains. Two of the irregular waves generated are ...
-
Yu, Kai (2009-05-15)An interface-preserving level set method is incorporated into the Reynolds- Averaged Navier-Stokes (RANS) numerical method for the time-domain simulation of green water effects. This generalized method can be used to ...
-
Bae, Yoon Hyeok (2010-01-16)Tie-down systems are used to fasten drilling rigs to the deck of offshore structures during harsh environmental conditions such as hurricanes. During Hurricane Ivan (2004) and Katrina (2005), a number of offshore structures ...
-
Park, Junyoung (2009-05-15)Theory and simulation results have demonstrated that four, variable speed flywheels could potentially provide the energy storage and attitude control functions of existing batteries and control moment gyros (CMGs) on a ...
-
Wang, Hao (2020-06-22)Nonlinear effects become more important in predicting the motions of a wave energy structure (WES), which is subject to large (relative to its dimensions) motion amplitudes. To model the WES more accurately, a time-domain ...
