Today, most of the shallow water sites are already occupied, and the industry is looking to install turbines at the deep water sites (water depth &gt; 50m). However, an OWT support structure designed with the conventional concepts becomes massive and expensive in deeper waters. In contrast, floating OWTs are more expansive than the bottom supported ones, and considered suitable for a water depth of 60 m or more. A novel support structure concept termed a \u2018bottom supported tension leg tower\u2019 (BSTLT) has been proposed recently and the possibility of using bottom supported structures in deeper waters is shown. In this paper, an extension of the BSTLT concept has been achieved using inclined tethers with a monopile. The preliminary technical feasibility including the sensitivity of the natural frequencies and dynamic analyses considering the in-place operating and the extreme design conditions has been studied for 50 m water depth. The results show that the proposed concept can be utilized to make the monopile based support structures more cost-efficient for the water depth stated above. <\/jats:p>","DOI":"10.1680\/jmaen.2021.001","type":"journal-article","created":{"date-parts":[[2021,8,13]],"date-time":"2021-08-13T07:32:55Z","timestamp":1628839975000},"page":"124-133","source":"Crossref","is-referenced-by-count":7,"title":["Bottom-supported tension leg towers with inclined tethers for offshore wind turbines"],"prefix":"10.1680","volume":"174","author":[{"given":"Mohammed","family":"Ishtiyak","sequence":"first","affiliation":[{"name":"Research Scholar, Department of Ocean Engineering and Naval Architecture, Indian Institute of Technology Kharagpur, Kharagpur, India (corresponding author: )"}]},{"given":"Arunjyoti","family":"Sarkar","sequence":"additional","affiliation":[{"name":"Assistant Professor, Department of Ocean Engineering and Naval Architecture, Indian Institute of Technology Kharagpur, Kharagpur, India"}]},{"given":"Tiago","family":"Fazeres-Ferradosa","sequence":"additional","affiliation":[{"name":"R&D sub-unit responsible, Faculty of Engineering of the University of Porto, Department of Civil Engineering, Hydraulics, Water Resources and Environmental Division, CIIMAR \u2013 Interdisciplinary Centre of Marine and Environmental Research, Marine Energy Research Group, Porto, Portugal"}]},{"given":"Paulo","family":"Rosa-Santos","sequence":"additional","affiliation":[{"name":"Associate professor, Faculty of Engineering of the University of Porto, Department of Civil Engineering, Hydraulics, Water Resources and Environmental Division, CIIMAR \u2013 Interdisciplinary Centre of Marine and Environmental Research, Marine Energy Research Group, Porto, Portugal"}]},{"given":"Francisco","family":"Taveira-Pinto","sequence":"additional","affiliation":[{"name":"Professor, Faculty of Engineering of the University of Porto, Department of Civil Engineering, Hydraulics, Water Resources and Environmental Division, CIIMAR \u2013 Interdisciplinary Centre of Marine and Environmental Research, Marine Energy Research Group, Porto, Portugal"}]}],"member":"140","reference":[{"key":"b1","doi-asserted-by":"publisher","DOI":"10.1016\/j.marstruc.2017.10.002"},{"volume-title":"Ansys Mechanical APDL Structural Analysis Guide","year":"2013","author":"Ansys Inc.","key":"b2"},{"volume-title":"Hydrodynamics of Offshore Structures","year":"1978","author":"Chakrabarti SK","key":"b5"},{"key":"b6","doi-asserted-by":"publisher","DOI":"10.1016\/j.jweia.2013.03.003"},{"volume-title":"Proceedings of European Offshore Wind Conference and Exhibition, Berlin, Germany","year":"2007","author":"de Vries WE","key":"b8"},{"volume-title":"World's Largest Offshore Wind Farm Fully Up and Running","year":"2020","author":"Durakovic A","key":"b11"},{"key":"b12","doi-asserted-by":"publisher","DOI":"10.1680\/jmaen.2017.26"},{"key":"b13","doi-asserted-by":"publisher","DOI":"10.1016\/j.coastaleng.2020.103671"},{"issue":"1","key":"b15","first-page":"1","volume":"12","author":"Johannessen K","year":"2002","journal-title":"International Journal of Offshore and Polar Engineering"},{"volume-title":"FAST User's Guide","year":"2005","author":"Jonkman JM","key":"b16"},{"key":"b17","doi-asserted-by":"crossref","unstructured":"Jonkman J, Butterfield S, Musial W and Scott G (2009) Definition of a 5-MW Reference Wind Turbine for Offshore Development.
