Response-Based Assessment of Operational Limits for Mating Blades on Monopile-Type Offshore Wind Turbines
Verma, Amrit Shankar; Jiang, Zhiyu; Ren, Zhengru; Gao, Zhen; Vedvik, Nils Petter (Journal article; Peer reviewed, 2019)Installation of wind-turbine blades on monopile-type offshore wind turbines is a demanding task. Typically, a jack-up crane vessel is used, and blades are individually lifted from the vessel deck and docked with the ... -
Sea state estimation based on vessel motion responses: Improved smoothness and robustness using Bezier surface and L1 optimization
Ren, Zhengru; Han, Xu; Verma, Amrit Shankar; Dirdal, Johann Alexander; Skjetne, Roger (Peer reviewed; Journal article, 2021)Floating structures oscillate in waves, where these wave-induced motions may be critical for various marine operations. An important consideration is thereby given to the sea states at the planning and operating stages for ... -
Structural Safety Assessment of Marine Operations From a Long-Term Perspective: A Case Study of Offshore Wind Turbine Blade Installation
Verma, Amrit Shankar; Gao, Zhen; Jiang, Zhiyu; Ren, Zhengru; Vedvik, Nils Petter (Chapter, 2019)A marine operation is a complex non-routine activity of limited duration carried out in offshore environment. Due to safety reasons, these operations are normally performed within specific sea state limits, which are derived ...
