3D numerical modelling of scour around a jacket structure with dynamic free surface capturing
(Peer reviewed; Journal article, 2020)This paper presents a numerical investigation of local scour with dynamic free surface capturing around a jacket structure. The hydrodynamics and resulting scour are calculated using the open-source CFD model REEF3D. The ... -
A macro-element pile foundation model for integrated analyses of monopilebased offshore wind turbines
(Journal article; Peer reviewed, 2018)The design of OWTs relies on integrated load analyses tools that simulate the response of the entire OWT (including the rotor-nacelle assembly, support structure and foundation) under combined aerodynamic and hydrodynamic ... -
Analysis of railway vehicle-track interaction performance in submerged floating tunnel subjected to wave excitations
(Journal article; Peer reviewed, 2024)Submerged Floating Tunnels (SFTs) are an innovative and appealing solution for the water crossing of railways over wide and deep waterbodies where it is challenging or even impractical to construct conventional bottom-founded ... -
Breaking Wave Interaction with a Vertical Cylinder and the Effect of Breaker Location
(Journal article; Peer reviewed, 2016)The open-source CFD model REEF3D is used to simulate plunging breaking wave forces on a vertical cylinder. The numerical results are compared with data from the experiments carried out at the Large Wave Channel, Hannover, ... -
CFD Investigations of Wave Interaction with a Pair of Large Tandem Cylinders
(Journal article; Peer reviewed, 2015)Wave forces and the flow field around cylinders placed in a periodic wave field are investigated with a numerical model using the Reynolds-averaged Navier–Stokes equations. The numerical model is validated by simulating ... -
Discussion of assumptions behind rule-based ice loads due to crushing
(Journal article; Peer reviewed, 2016)Forecasts and trends indicate an increase in marine operations in polar waters. The design of new ships for severe polar conditions is usually solved via theoretical considerations that are combined with previous experience ... -
Experimental and Numerical Investigation of Sloshing under Roll Excitation at Shallow Liquid Depths
(Journal article; Peer reviewed, 2017)This paper investigates sloshing at shallow-liquid depths in a rectangular container by using experimental and numerical methods. A motion platform is used to perform a prescribed periodic rotational motion to excite the ... -

Modelling of soil-structure-interaction for flexible caissons for offshore wind turbines
(Journal article; Peer reviewed, 2018)Published foundation models and procedures for calculation of caisson foundation response typically assume a rigid caisson in deformable soil. However, recent published measurement data from a prototype suction bucket ... -
Modelling the flow around and wake behind net panels using large eddy simulations
(Peer reviewed; Journal article, 2021)The fluid flow through a fixed net panel is investigated using large eddy simulations. Computational meshing strategies suitable for smooth and fabric twines are proposed. Numerical validations are conducted by comparing ... -
Numerical Investigations of the Hydrodynamics of an Oscillating Water Column Device
(Journal article; Peer reviewed, 2015)An oscillating water column (OWC) device is a renewable energy device that is used to extract ocean wave energy through the action of waves on a partially submerged chamber consisting of an air and a water column. The ... -
Properties of breaking irregular waves over slopes
(Peer reviewed; Journal article, 2020)The present study numerically investigates the breaking and spectral characteristics and geometric properties of breaking irregular waves over slopes for different incident waves. The growth of wave non-linearity and wave ... -
Reduction of the wave propagation error of a sigma grid based numerical tank using a vertical spacing based on the constant truncation error
(Peer reviewed; Journal article, 2021)Numerical wave models that solve the Laplace equation for the velocity potential with a -grid in the vertical direction have been proven to be flexible and efficient. However, it is observed that the dispersion relation ... -
Uncertainty assessments of structural loading due to frst year ice based on the ISO standard by using Monte-Carlo simulation
(Peer reviewed; Journal article, 2020)Sea ice is the major source of loading for structural design in cold regions. The intrinsic properties of sea ice are generally associated with high degrees of uncertainty due to ice growth taking place during different ...
