Research Projects

PARTRES

Particle Resolving Fluid-Sediment Interaction

ERC Consolidator Grant (CoG2021)

ongoing

In order to represent sediment transport processes in a more realistic way, the goal of the project is to build a particle-centric sediment transport model. The important processes of sediment transport, soil deformation, motion of large elements during extreme hydrodynamic events (EHE) are captured through an interdisciplinary and holistic approach in order to better understand and identify EHE related damages at coasts and rivers. All relevant physics will be integrated in the numerical framework REEF3D and the multi-scale aspect will be achieved through hydrodynamic coupling.

B-WAVESs

Bottom Fixed Offshore Wind Turbines in Extreme Waves

NFR KPN

Industry partners: Equinor, COWI, DNV Aker Solutions

Research partners: SINTEF Ocean, Norwegian Meteorological Institute

ongoing

Extreme wave loads represent one of the main design load conditions for the design of offshore wind turbines. Such may both trigger significant structural dynamics and overloading. As part of the project, breaking waves for nonlinear wave kinematics are captured with the efficient potential flow model REEF3D::FNPF. Near-field hydrodynamics and slamming loads are predicted with REEF3D::CFD.

IPIRIS

Improving Performance in Real Sea

NFR KPN

Industry partners: Kongsberg Maritime, Havyard Design & Solutions, Vard Design

Research partners: SINTEF Ocean

ongoing

Develop an algorithm within REEF3D for the accurate simulation of ship motions in severe waves to evaluate the added resistance problem in realistic sea states. 

SurfWave

Coastal Wave Modelling in the World Surfing Reserve of Ericeira

EEA Iceland Lichtenstein Norway grants

Industry partners: blueOasis

ongoing

This Portugal-Norway collaboration project works on delivering detailed wave information using REEF3D. With crucial importance to the local community in relationship to surfing, tourism, offshore wind and fishing activities, while maintaining the environmental goals of the World Surf Reserve, a better understanding of the coastal wave processes will be gained.
