... Abstract The U.S. plans to install 30GW of offshore wind by 2030. However, the lack of Jones-Act compliant installation vessels means that alternative installation strategies will have to be used in the near to mid-term. One such strategy is to use Jones-Act classed barges or purpose built...

... solution of grid upgrades, energy storage, and advanced power electronics will be needed to account for this issue, the exact scope of the problem is not well defined. By analyzing the Eastern Interconnection (EIC) as though it were powered entirely by new 15 MW offshore wind by 2050, we can place...

... the Atlantic Continental Shelf associated with offshore wind farm developments. Due to its friable nature, glauconite affects the geotechnical properties of the sediments in which it forms. Geotechnical laboratory tests performed on glauconite sand samples reveal a wide range in particle size gradation...

... Unit (ESDU) models. These comparisons are used to understand the applicability of the wind models to offshore hurricane conditions and assess the design principles of offshore structures. offshore wind wind profile hurricanes turbulence intensity LIDAR Proceedings of the ASME 2022 41st...

... Abstract With the recent surge in development of offshore wind in the Baltic Sea, Bohai Sea and other ice-prone regions, a need has arisen for new basin tests to qualify the interaction between offshore wind turbines and sea ice. To this end, a series of model tests was performed at the Aalto...

... Abstract The selection of a feasible support structure for the site-specific environmental conditions helps in reducing the capital cost of the offshore wind turbines. As the study location falls under shallow water depth, the bottom fixed structures such as monopile, tripile and jacket have...

... Abstract The paper elaborates on the bearing mechanics of suction caissons serving as the foundation system of offshore wind turbines (OWTs) supported on jacket structures. As axial loading governs foundation design in this configuration, the study proceeds to a numerical investigation...

... Abstract Ocean renewable energy has a central role to play in decarbonizing the global energy system. The emergence of new technologies such as floating wind farms will significantly increase offshore wind deployment by providing access to large areas of the seabed that are not suitable...

... Abstract As of now, only a small number of offshore foundations, related to offshore wind energy, were decommissioned in Europe. With a diameter up to nine meter, an embedment of about 40 meter and a set up effect over 25 years, the necessary force to pull the pile out of the seabed can...

... Abstract Offshore wind structures are being designed for seismically active areas. Load calculations can be performed in an integrated way or using a superelement approach. This study aims to demonstrate that these two approaches can give equivalent results when earthquake excitations...

... Abstract The complete decommissioning of an offshore wind farm can be considered as a highly complex and hazardous approach. An unknown number of variables and unforeseen circumstances are involved in the decommissioning process. On the one hand the decommissioning of the top structure...

... Abstract Renewable Energies become more and more important in industries and society all over the world. In Germany, offshore wind farms generated 49 % of the renewable energies in 2018. Monopiles are the preferred system for the foundation of offshore wind turbines in water depths up to 40 m...

... Abstract Subsea export power transmission cables for offshore wind farms are being installed more extensively year-on-year due to the increasing demands for power output from renewable sources. With the increasing number of installations, the number of cable failures during installation has...

... Abstract Support structure fatigue is a key component in determining the structural lifetime of an offshore wind turbine (OWT). As the currently installed assets age, turbine operators are exploring options for lifetime extension to potentially increase the long-term financial return. Strain...

... be restricted by practical considerations, and installation might be conducted more based on engineering judgement rather than analysis. This leads to the question of how important the optimal sensor placement is, and if fewer sensors suffice to extract the modal parameters. In this work, an offshore wind...

... Abstract Offshore wind technology is at the forefront of exploiting renewable energy at sea. The latest innovations in the field comprise floating wind turbines deployed in deep waters that are capable of intercepting the stronger, less turbulent winds farther away from the landmass. Despite...

... Abstract The focus of the Offshore Code Comparison Collaboration, Continuation, with Correlation and unCertainity (OC6) project, which operates under the International Energy Agency Wind Task 30, is to refine the accuracy of engineering tools used to design offshore wind turbines. In support...
