Comparative Study of the Path Integration Method and the Stochastic Averaging Method for Nonlinear Roll Motion in Random Beam Seas
(Journal article; Peer reviewed, 2017)In this work, the path integration method and the energy-based stochastic averaging method are introduced in order to study the stochastic responses of ship roll motion in random beam seas. Based on the Markov property of ... -
Fatigue Damage Comparison of Mechanical Components in a Land-based and a Spar Floating Wind Turbine
(Journal article; Peer reviewed, 2015)This paper investigates the fatigue damage of the gears and bearings in a land-based and a spar-type floating wind turbine. The reference 5 MW NOWITECH gearbox is used on a land-based and a floating spar wind turbine. ... -
Long-term stochastic extreme response analysis of floating bridges
(Journal article; Peer reviewed, 2017)For the assessment of extreme responses needed in design of marine structures, a full long-term analysis is recognized as the most accurate approach. However, due to the very large number of structural response analyses ... -
On model-based system approach for health monitoring of drivetrains in floating wind turbines
(Journal article; Peer reviewed, 2017)This paper deals with the health monitoring of a wind turbine drivetrain in a system perspective. A 5-MW reference drivetrain installed on a spar type floating wind turbine is selected. Degradation and damage in the main ... -
Vortex-induced vibrations of a vertical riser with time-varying tension
(Journal article; Peer reviewed, 2017)Numerical simulations of a vertical tensioned riser in a sheared flow are performed, where the riser top end oscillates sinusoidally in the vertical direction. The oscillating top-end motion causes tension variations and ...
