In [4], it has been shown that energy ships deployed far-offshore in the North Atlantic Ocean may achieve capacity factors over 80% using weather-routing. The present paper complements this research by investigating the capacity factors of energy ships harvesting wind power in the near-shore. This paper also compares energy production by energy ships with stationary floating wind turbines deployed near-shore. Two case studies are considered: St. Pierre et Miquelon and Ile de Sein.The methodology is as follows. The design of the energy ship considered in this study is presented. It was developed using an in-house Velocity, and Power Performance Program (VPPP) developed at LHEEA [2]. The velocity and power production polar plots of the ship were used as input to a modified version of the weather-routing software QtVlm. This software was then used for capacity factor optimization using 10m altitude wind data analysis which was extracted from the ERA-Interim dataset provided by the European Centre for Medium-Range Weather Forecasts (ECMWF). Three years (2015, 2016, and 2017) data for January (winter) and July (summer) are considered.The capacity factor optimization is currently on-going. Results will be presented and discussed in the paper. Results will include detailed power performance results and route traces for both wind power conversion systems (energy ship and floating offshore wind turbine).&nbsp;References[1]&nbsp; J. Kim, C.

ASME 2021 International Offshore Wind Technical Conference (IOWTC2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
