The UK has an outstanding record of research in Wave Structure Interaction (WSI) and good reason to maintain this status, particularly in the light of its leading position in the development of modern offshore renewable energy (ORE) technologies. However, the challenges facing the WSI community in developing the necessary complex, multi-physics, multi-component suit of Computational Fluid Dynamics (CFD) software are significant and represent a goal that can only be achieved through a collaborative code development environment. In response, a Collaborative Computing Project (CCP) has been established to serve the UK research community in the area of WSI. The project, which has been active for 4 years, brings together computational scientists, CFD specialists and experimentalists with the shared objective of developinga Numerical Wave Tank (NWT) facility that complements existing and future UK experimental laboratory facilities and supports leading-edge research in marine, coastal and offshore engineering. The overarching aims of the CCP-WSI Project are to develop and maintain a robust and efficient computational WSI modelling tool, build the community of researchers and developers around WSI and provide a focus for software development and code rationalization. The combined CCP-WSI and SIG-WSI network is a growing international group of over 115 researchers, spanning academia and industry in 5 continents. The group has identified a number of key WSI challenges/priorities and has co-created a roadmap for WSI code development through industry focus group workshops with 75 attendees. The CCP-WSI has advanced understanding of the applicability and reliability of WSI through a set of internationally recognised Blind Test series’ involving 50 participants. The CCP-WSI Blind Test activities have been presented in dedicated sessions at 3 international conferences with 25 papers published in 3 special issue journals. Over 80 journal publications have been generated by the CCP WSI team and over 20 presentations have been given at national and international conferences. A number of pilot projects with industry, outreach activities with school children and public audiences have also been delivered. Training has been provided to the community with 76 attendees, including training in software engineering, specific code development, the use of the CCP-WSI Code Repository and specific WSI developments and a week-long Hackathon for intense collaborative code development. The CCP-WSI Code Repository and clearing house provides a platform for co-creation and sharing of open-source WSI code for community use, and is maintained by the CCP-WSI Organisation on Github with over 45 users and more than 300 commits. The CCP-WSI Data Repository supports a growing database of benchmarking test cases for community use and validation practices.
