Radial Consolidation of Pore Pressure Induced by Pile Driving
Bergset, Knut-Helge (Master thesis, 2015)Pile installation is recognized to significantly disturb the surrounding clay and cause changes in total and effective stresses around the pile. In this thesis, a numerical model is used to simulate pile installation and ... -
Radial consolidation of pore pressure induced by pile installation
Olaussen, Anne Mestvedt (Master thesis, 2016)The soil surrounding a driven pile is subjected to varying degrees of soil disturbance during the installation, and experiences a complex combination of loading, unloading and reloading in the course of the life cycle of ... -
Rate effects increasing lateral capacity of monopiles
Wahl, M.M.; Hamre, L.; Eiksund, Gudmund Reidar; Tjelta, Tor-Inge; Suzuki, Pauline; Rose, M. (Chapter, 2023)Lateral soil resistance is a key driver for the design of offshore wind monopile foundations but current practice does not explicitly consider the effects of loading rate. This study investigates the effect of loading rate ... -

(Journal article; Peer reviewed, 2018)The cost of offshore wind energy production has to be reduced continuously to improve its competitiveness compared to other energy sources. To contribute to this goal, a 4- year research project REDWIN – REDucing cost of ... -
Reliability Analysis of Monopile Foundations for Offshore Wind Turbines
Depina, Ivan (Doctoral thesis at NTNU;2016:171, Doctoral thesis, 2016)Initiated by the increasing energy demands and instabilities in oil and gas prices there is an ongoing transition from the conventional to the renewable energy sources across Europe. The goal is to satisfy 20% of the energy ... -
Reliability analysis with Metamodel Line Sampling
Depina, Ivan; Le, Thi Minh Hue; Fenton, Gordon A.; Eiksund, Gudmund Reidar (Journal article; Peer reviewed, 2016)This paper presents an approach for reliability analysis of engineering structures, referred to as Metamodel Line Sampling (MLS). The approach utilizes a metamodel of the performance function, within the framework of the ... -
Reliability-based Design of a Monopile Foundation for Offshore Wind Turbines based on CPT Data.
Overgård, Ida Elise (Master thesis, 2015)A reliability-based design optimization (RBDO) of a monopile foundation for offshore wind turbines is conducted to optimize monopile design criteria by explicitly accounting for the effects of uncertainties. The RBDO in ... -
Reliability-based design optimization with Cross-Entropy method
Ghidey, Hiruy (Master thesis, 2015)Implementation of the Cross-entropy (CE) method to solve reliability-based design optimization (RBDO) problems was investigated. The emphasis of this implementation method was to solve independently both the reliability ... -
Response of Laterally Loaded Monopiles
