Effects of Wind-Wave Misalignment on a Wind Turbine Blade Mating Process: Impact Velocities, Blade Root Damages and Structural Safety Assessment
Verma, Amrit Shankar; Jiang, Zhiyu; Ren, Zhengru; Gao, Zhen; Vedvik, Nils Petter (Peer reviewed; Journal article, 2020)Most wind turbine blades are assembled piece-by-piece onto the hub of a monopile-type offshore wind turbine using jack-up crane vessels. Despite the stable foundation of the lifting cranes, the mating process exhibits ... -
Elastic Properties of Flexure Patterns - Characterization, Classification and Development of Design Principles by Parametric Finite Element Analyses
Østmo, Oddvin Agnalt (Master thesis, 2018)A flexure pattern increases the ability of a plate to undergo large elastic deformations. It is characterized as a 2D mechanical metamaterial that consist of flexures configured in a pattern that increase the compliance ... -
Experimental and numerical investigation of filled thermoset polymers as mechanical interface in fine tolerance applications
Tronvoll, Sigmund Arntsønn (Master thesis, 2015)As a part of reducing costly processes in production of marine thrusters, casting and machining of large steel parts is proposed to be replaced by welding of smaller elements. This does however require a procedure for ... -
Experimental verification of the elastic response in a numeric model of a composite propeller blade with bend twist deformation
Rokvam, Sondre Østli; Vedvik, Nils Petter; Mark, Lukas; Rømcke, Eivind; Ølnes, Jon; Savio, Luca; Echtermeyer, Andreas (Journal article; Peer reviewed, 2021) -
Explicit Structural Response-Based Methodology for Assessment of Operational Limits for Single Blade Installation for Offshore Wind Turbines
Verma, Amrit Shankar; Zhao, Yuna; Gao, Zhen; Vedvik, Nils Petter (LNCE;volume 23, Chapter, 2019)The growing requirements of large-sized offshore wind turbines require heavier components to be lifted to large heights using installation vessels. This imposes a substantial risk of impact to the lifted components especially ... -
Hydrodynamic Design Principles and Structural Verification of a Hydrofoil Concept for Kiteboarding
Sjøwall, Kristoffer (Master thesis, 2022)Bruken av hydrofoiler i kiteboarding har de siste ˚arene blitt stadig mer populært og vil for første gang bli inkludert i de olympiske leker i 2024. Siden oppstarten har den primære utviklingsinnsatsen vært˚a optimalisere ... -
Impact assessment of a wind turbine blade root during an offshore mating process
Verma, Amrit Shankar; Jiang, Zhiyu; Vedvik, Nils Petter; Gao, Zhen; Ren, Zhengru (Journal article; Peer reviewed, 2019)Single-blade installation is a popular method for installing blades on bottom-fixed offshore wind turbines. A jack-up crane vessel is often employed, and individual blades with their roots equipped with mechanical joints ... -
Integration Tools for Design and Process Control of Filament Winding
Skjærholt, Inger (Master thesis, 2012)Filament winding is a fabrication method for composite material structures, in which fibres are wound around a rotating mandrel. It is a versatile and dexterous process especially well-suited for creating and optimizing ... -
