Computational Fluid Dynamics Reproduction of Nonlinear Loads on a Vertical Column during Extreme Irregular Wave Events
(Journal article; Peer reviewed, 2018-07-12)Recently, a method for numerical reproduction of measured irregular wave events has been developed. The measured motion of the wave maker flaps defines the wave kinematics at the boundary of the numerical simulation in ... -
Distributed Co-Simulation of Maritime Systems and Operations
(ASME digital collection;OMAE-17-1037, Journal article; Peer reviewed, 2018-05)Here, we present the concept of an open virtual prototyping framework (VPF) for maritime systems and operations that enables its users to develop reusable component or subsystem models, and combine them in full-system ... -
Evaluation of Nonlinear Material Behavior for Offshore Structures Subjected to Accidental Actions
(ASME digital collection;OMAE-17-1044, Journal article; Peer reviewed, 2018-01-09)Evaluation of the nonlinear structural response of any structure is a challenging task; a range of input parameters are needed, most of which have significant statistical variabil- ity and the evaluations require a high ... -
Hydrodynamic Coupling of Viscous and Nonviscous Numerical Wave Solutions Within the Open-Source Hydrodynamics Framework REEF3D
(Journal article; Peer reviewed, 2022)A comprehensive understanding of the marine environment in the offshore area requires phase-resolved wave information. For far-field wave propagation, computational efficiency is crucial, as large spatial and temporal ... -
Hydrodynamic loads on net panels with different solidities
(Journal article; Peer reviewed, 2021)Drag forces on nets represent the largest contribution to hydrodynamic loads on traditional fish farms, and will have a large impact on total loads on new designs utilizing netting as containment method. Precise methods ... -
Load Coefficients and Dimensions of Raschel Knitted Netting Materials in Fish Farms
(Journal article; Peer reviewed, 2022)New types of fish farms are often larger and structurally more complex than conventional fish farming structures, and associated challenges concerning safety and costs increase correspondingly. Thus, increased precision ... -
Lumped, constrained cable modeling with explicit state-space formulation using an elastic version of Baumgarte stabilization
(Peer reviewed; Journal article, 2021)This paper presents a modeling approach for efficient simulation of slender structures, such as wires, cables and ropes. Lumped structural elements are connected using constraints. These are solved explicitly, using an ... -
On the significance of the higher-order stress in riser vortex-induced vibrations responses
(Journal article; Peer reviewed, 2019-02)Vortex-induced vibrations (VIV) can lead to fast accumulation of fatigue damage and increased drag loads for slender marine structures. VIV responses mainly occur at the vortex shedding frequency, while higher harmonics ... -
Real-Time Parameter Estimation of a Nonlinear Vessel Steering Model Using a Support Vector Machine
(Journal article; Peer reviewed, 2019-06-19)The least-square support vector machine (LS-SVM) is used to estimate the dynamic parameters of a nonlinear marine vessel steering model in real-time. First, maneuvering tests are carried out based on a scaled free-running ... -
REEF3D Wave Generation Interface for Commercial Computational Fluid Dynamics Codes
(Peer reviewed; Journal article, 2021)In recent years, computational fluid dynamics (CFD) developments have shown a trend to combine Reynolds-averaged Navier–Stokes (RANS) CFD simulation with other methods such as wave theories or velocity potential-based ... -
Representation of 3-h Offshore Short-Crested Wave Field in the Fully Nonlinear Potential Flow Model REEF3D::FNPF
(Journal article; Peer reviewed, 2022)Stochastic wave properties are crucial for the design of offshore structures. Short-crested seas are commonly seen at the sites of offshore structures, especially during storm events. A long time duration is required in ...
