OC6 Phase IV: Validation of CFD Models for Stiesdal TetraSpar Floating Offshore Wind Platform

Wind Energy, Volume 28, Issue 1, January 2025.
ABSTRACT With only a few floating offshore wind turbine (FOWT) farms deployed anywhere in the world, FOWT technology is still in its infancy, building on a modicum of real‐world experience to advance the nascent industry. To support further development, engineers rely heavily on modeling tools to accurately portray the behavior of these complex systems

Control‐Oriented Modelling and Adaptive Parameter Estimation for Hybrid Wind‐Wave Energy Systems

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Different with the traditional hybrid wind‐wave energy system models that are established by using the boundary element method (BEM), devoting to understanding the hydrodynamic responses and performance analysis. This paper proposes a control‐oriented model of the hybrid wind‐wave energy system with the coupled aero‐hydro‐mooring dynamics. The obtained

Component‐Based Modeling of Steel–Concrete Composite Endplate Connections Under Fire Conditions

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
In fire scenarios, the performance of connections in composite structures differs significantly from that in noncomposite steel structures. To accurately simulate the high‐temperature behavior of composite endplate connections, a component‐based model has been developed and integrated into the Vulcan software.

Development of Transition Structures between Overhead Rigid Conductor Line and Catenary-Type Contact Line

Quarterly Report of RTRI, 2008
In order to adopt rigid conductor lines in tunnels of small sections, it is necessary to install a transition structure just outside the tunnel to allow a smooth pantograph shift between the catenary-type contact line and the rigid conductor line. However, the present transition structure is complicated, has inferior current collection characteristics ...
