On 9 and 10 May 2022, at the Institute of Hydro-Engineering of the Polish Academy of Sciences, a meeting of members of an international consortium implementing the project entitled "Numerical modeling of liquefaction around marine structures" (acronym NuLIMAS) was held. The project is funded under the ERA-NET MarTERA 2019 program and will be implemented from 1 September 2020 to 31 August 2023. The aim of the work is to experimentally recognize and theoretically describe the phenomena occurring immediately before, during and after the liquefaction of soil. The project consortium consist of the following institutions:

• Technische Universität Braunschweig,
• Großmann Ingenieur Consult (GICON),
• WIKKI Gesellschaft für numerische Kontinuumsmechanik mbH R&D,
• BM SUMER Consultancy & Research R&D,
• PROJMORS Biuro Projektów Budownictwa Morskiego sp. z o.o.,
• IBW PAN.

On the first day of the meeting, representatives of project partners discussed the current state of the design work. They also had the opportunity to get acquainted with the research equipment used at the IBW PAN and took part in experiments carried out in the Geotechnical Laboratory, Wave Flume and Hydraulic Laboratory.

During the second day of the meeting, a technical trip was organized to the site of the investment related to the Vistula Spit Channel. The members of the consortium got acquainted with the technological solutions used during the implementation of this key hydrotechnical investment. They also had the opportunity to talk to representatives of NDI and a designer from PROJMORS, who answered questions related to the solutions used in the area of the lock, shipping channel, breakwaters and artificial island. The last part of the trip was a cruise to an artificial island built on the Vistula Lagoon.

We hope that during the two days of the project meeting we were able to combine elements of theoretical, experimental and field research in the field of hydrotechnics. Our guests’ opinions about the meeting can be found at:
