Shin, Dongil (2020-10-29)This dissertation presents a novel approach for modeling and analyzing a geared rotor-bearing system including nonlinear forces in the gear set and the supporting fluid film journal bearings. Co-existing, steady-state, ...
-
Penugonda, Mourya (2018-06-08)This study is to compare and validate two models for random wave transformation with experimental data. Both models are based on frequency domain KdV equation. First model is a modified version of KdV equation which was ...
-
Kang, Heonyong (2011-08-08)As a comparative study, the global performance of two cases for a floating harbor system are researched by numerical analysis and compared with results from experiments: one is a two-body case such that a floating quay is ...
-
Yang, Chan K. (2010-07-14)Nonlinear coupling problems between the multiple bodies or between the mooring/riser and the offshore platform are incorporated in the CHARM3D-MultiBody, a fully coupled time domain analysis program for multiple bodies ...
-
Jang, Hakun (2018-11-14)One of the greatest challenges of developing the arctic regions is the harsh environmental conditions caused by the presence of ice. When offshore structures interact with ice, significant structural motion is induced by ...
-
Min, Hyunseong (2018-04-27)Hywind, the world’s first operational Floating Offshore Wind Turbine (FOWT), is constrained by a delta mooring system to improve the yaw station-keeping capacity. In this study, a mooring line-simulation code in COUPLE-FAST ...
-
Kim, Gyeongbo 1978- (2012-09-19)Tsunamis are one of the most catastrophic natural events impacting coastal regions often generated by undersea earthquakes. Nevertheless, in enclosed basins, i.e., fjords, reservoirs and lakes, subaerial or submarine ...
-
Peng, Cheng (2015-03-03)Floating offshore wind turbine (FOWT) attracts more and more attention for harnessing wind power over the surface of relatively deep ocean water, where steady and strong wind occurs. Although it has been shown that the ...
-
Lu, Hang (2012-10-19)With the increasing developments of exploiting oil and natural gas in deep water and harnessing renewable (wave and wind) energy in the sea, mooring lines and risers are widely deployed to position the related floating ...
-
Felix Gonzalez, Ivan (2015-03-03)Due to size limitations of wave basins worldwide it is necessary to employ statically equivalent truncated mooring and riser systems to test floating systems to be deployed in deep and ultra-deep waters. A procedure for ...
-
Cho, Yong Suk (2015-07-31)Numerical modeling of a particular Floating Liquefied Natural Gas (FLNG) facility, targeting on Prelude FLNG, was done to find an appropriate design of the FLNG including downtime in the specific field conditions. Hull/mooring ...
-
Tavassoli, Armin (2016-11-30)This Record of Study presents the author’s experience in the capacity of riser lead and technical advisor working on multiple engineering and management project assignments by Cuneiform Offshore Consulting (Cuneiform). ...
-
Kim, Hansung (2020-03-19)The Digital Twin (DT) is cited as one of the key concepts associated with Industry 4.0 waves. In fact, the concept of DT is not new and has lasted for over 10 years. In recent years, the clarity of improved technologies ...
-
Somayajula, Abhilash Sharma (2017-04-24)Traditionally ships are designed to be symmetric about their centerline which makes head seas a very safe heading for roll motion stability. However, in the recent years several incidents of large amplitude roll motion in ...
-
Bandas, John (2012-07-16)A system of ordinary differential equations (ODE) is constructed for an air cushion vehicle (ACV). The system is simplified to an equation for the balance of the vertical forces and the equation for the adiabatic compression ...
-
Semi-Active Magneto-Rheological Damper and Applications in Tension Leg Platform / Semi-Submersible Kang, Hooi Siang (2015-12-14)A reliable and cost-effective way to protect the hydrocarbon production modules in harsher environments has been crucial to the success of offshore oil and gas projects. Nevertheless, the excessive tension variations in ...
-
Jamnongpipatkul, Arada (2012-02-14)In this research the stochastic nonlinear dynamic behaviors and probability density function of ship rolling are studied by nonlinear dynamic method and probability theory. The probability density function of rolling ...
-
Kim, Kyung Sung (2014-05-07)The coupling and interactions between ship motions and inner-liquid tank sloshing have been investigated by a coupled program between ship motion and sloshing analysis programs. For the sloshing program, Moving Particle ...
