The 12th International Workshop on Ship and Marine Hydrodynamics 28 August to 1 September 2023 Aalto University, Espoo, Finland Editors Eur.Ing. Dr. Spyros Hirdaris CEng FRINA, FSNAME Aalto University, Finland AND Professor Decheng Wan Shanghai Jiao Tong University, China The 12th International Workshop on Ship and Marine Hydrodynamics (IWSH 2023) was held from the 28th of August to the 1st of September 2023 at Aalto University, Finland. Aalto University was established in 2010 as a merger the Helsinki University of Technology (HUT), the Helsinki School of Economics and the University of Art and Design of Helsinki. Marine and Arctic Technology has been solid part of the well cherished traditions of HUT dating back to the 19th century.IWSH inaugurated by Prof. Zaojian Zou of Wuhan University of Technology in 1999. Early national events were organised by Wuhan University of Technology (2001,2003), Shanghai Jiao Tong University (2005), Jiangshu University of Science and Technology (2007) and Harbin Engineering University (2009).In 2011 Professor Decheng Wan organised the first international version of the workshop at Shanghai Jiao Tong University. Since then, the event has been organised by Seoul National University - South Korea (2013), the University of Strathclyde - UK (2015), the National Taiwan Ocean University (2017) and Hamburg University of Technology - Germany (2019). The 2021 edition of IWSH did not take place because of the COVID-19 pandemic. The “all-inclusive” nature of the 12th sequel of the workshop held in 2023 included scientific and social activities, fostering opportunities for networking.The workshop focused on publications of relevance to ship dynamics, hydrodynamics, wave mechanics, sea loads and responses, fluid structure interactions, ship resistance and propulsion, etc. Notably, emerging multiphysics methods with application on both ships and ocean engineering including renewable energies were evident. Six keynotes were delivered by Dr. Nuno Fonseca of SINTEF (Norway), Dr. Sime Malenica of Bureau Veritas (BV, France), Alessandro Iafrati of Istituto di iNgegneria del Mare (INM, Italy), Dr. Michel Visonneau of Centre National de la Recherche Scientifique (CNRS, France), Professor Stefano Brizzolara of Virginia Technological Institute and State University (USA) and Professor Yonghwan Kim of Seoul National University (South Korea), were invited to foster top level discussion on relevant subjects. As part of the workshop proceedings the main event sponsor, SINTEF Ocean (Norway) hosted a special session of their International Collaboration Network in Marine Technology.The oral technical program was organized in parallel sessions. In these proceedings, the papers are organized by major themes. The themes are: (1) Ship dynamics, (2) Wave mechanics, (3) Fluid Structure Interactions, (4) Ship motions and sea loads, (5) Ocean Engineering, (6) Ship resistance, (7) Marine propulsion.The workshop confirmed that the complexity of the subject as related to conventional and emerging technologies attracts a great deal of interest of relevance to engineering science and technological innovation. The field of ship and marine hydrodynamics remains more than relevant for the safety and sustainability of the ship and ocean engineering sectors.
