4. Can dual pulsed scanning Doppler wind lidars measure turbulence coherence?

Prof. Etienne Cheynet (University of Bergen)

Paper Contribution

This study presents one of the first validations of horizontal turbulence co-coherence estimated using dual synchronised long-range pulsed Doppler wind lidars, with sonic anemometers as reference. The experiment was conducted in March 2020, where two WindCube 100S lidars operated in fixed line-of-sight mode with parallel beams directed towards two 3D sonic anemometers mounted on 10 m-high...

108. Dynamic response of a 15-MW floating wind turbine on semi-submersible, spar, and tension-leg platforms under varying atmospheric stability conditions

Lennart Vogt (University of Stavanger)

Paper Contribution

The dynamic response of a 15-MW floating wind turbine supported by semi-submersible, spar, and tension-leg platforms is investigated through a series of aero-hydro-servo-elastic simulations. The turbine is subjected to turbulent inflow and irregular waves across a range of mean wind speeds and atmospheric stability conditions. Wind field and wave characteristics are derived from observations...

82. Experimental Evaluation of Bridge Deck Aerodynamic Coefficients in a Short Open-Section Wind Tunnel

Mr Carl Oscar Høimark Meyer-Johansen (PhD Student)

Paper Contribution

Accurate determination of cross-sectional aerodynamic forces - lift, drag, and pitching moment - is fundamental to evaluating the stability and wind-induced response of long-span suspension bridges.

This paper assesses the suitability of a short open-section wind tunnel facility for prediction of the aerodynamic force coefficients of the streamlined box girder of the Lysefjord Bridge. The...

5. Field measurement of the wind Flow Downstream of a Parabolic Trough Solar Collector Array

Mr Yuanchen Wan (University of Bergen)

Paper Contribution

This study investigates how atmospheric turbulence is modified within and downstream
of a parabolic trough solar collector array using full-scale field measurements from
Nevada Solar One (USA). The measurement setup included one mast outside the array and
three masts downstream of the first three collector rows. Each mast carried three 3D
sonic anemometers at 3.5 m, 5 m, and 7 m above...

15. HAZID and Qualitative Risk Analysis (QRA) of Gangway-Based Personnel Transfers to Offshore Wind Turbine Structures

Ove Tobias Gudmestad (University of Stavanger, Norway)

Paper Contribution

The safe transfer of personnel to offshore wind structures in order to carry out maintenance activities remains a critical operation, especially in regions with severe environmental conditions, such as the Southern North Sea. Several methods exist for accessing OWTs; gangway-based Walk-to-Work (W2W) systems are widely used. However, crew transfer operations pose various challenges and severe...

83. Influence of wall treatment on flow around a cantilevered ellipsoid

Dr Knut Erik Teigen Giljarhus (University of Stavanger)

Plenary Contribution

This study investigates high-Reynolds-number flow around a cantilevered ellipsoid using steady Reynolds-averaged Navier–Stokes simulations. The focus is on how near-wall mesh resolution and wall-function treatment affect the predicted flow. Unlike sharp-edged bluff bodies, for which separation is largely fixed by geometric discontinuities, the separation location on a smoothly curved body...
