2. 1. Mooring dynamics for wave energy applications

   Author : Johannes Palm; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hp adaptivity; Wave energy; Coupled simulations; CFD; Discontinuous Galerkin methods; OpenFOAM; Mooring dynamics; Snap loads; RANS;

   Abstract : This work aims to increase the modelling accuracy of two important problems for the wave energy industry. One concerns the mooring dynamics in the presence of snap loads (shock waves in cable tension). The other is related to nonlinear effects in the resonance region of moored wave energy converters (WECs). READ MORE

4. 2. Dynamics and Extreme Value Problems for Moored Floating Platforms

   Author : Yungang Liu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quasi-static; frequency-domain; extreme value; convolution; floating platform; low-frequency; time-domain; mooring cable; wave-frequency;

   Abstract : This research deals with the dynamic response analyses and extreme value problems of moored floating platforms. It can be divided into three major subjects: first, the analysis of single cables and cable induced mooring damping; second, the dynamic analysis of the moored platforms, with special emphasis on the damping mechanisms and generation of the low-frequency excitation force time series; and third, the extreme wave-frequency responses and the combination of the low-frequency and wave-frequency extreme responses.

5. 3. Developing Computational Methods for Moored Floating Wave Energy Devices

   Author : Johannes Palm; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave Power; RANS simulations; Discontinuous Galerkin; Mooring Dynamics;

   Abstract : Floating point absorbers are a common class of wave-power devices typically designed to move with large amplitude in energetic waves. This stands in sharp contrast to traditional marine design, where the wave-excited motions of the structure are preferably kept to a minimum. READ MORE

6. 4. Analysis of Power Performance and Mooring Fatigue Damage for Wave Energy Parks

   Abstract : Wave energy has been recognized as a promising alternative to traditional energy sources due to its cleanliness and sustainability. To harness this energy, wave energy converters (WECs) are utilized. READ MORE

7. 5. Extreme wave conditions and the impact on wave energy converters

   Author : Eirini Katsidoniotaki; Malin Göteman; Vincent Neary; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extreme waves; wave energy converters; CFD; OpenFOAM; environmental contours; focused waves; breaking waves;

   Abstract : The amount of energy enclosed in ocean waves has been classified as one of the most promising renewable energy sources. Nowadays, different wave energy conversion (WEC) systems are being investigated, but only a few concepts have been operated in a sea environment. READ MORE
