Crystal Bach is a luxury Rhine-class river cruise ship built for Crystal River Cruises at the MV Werften shipyard in Wismar, Germany, and delivered in 2017 as the first vessel of the Rhine-class series designed for premium river cruising in Europe.

Within this project, Prime Baltic Associaties carried out insulation works together with installation of catering areas and piping systems, including welding and plumbing works supporting the vessel’s onboard service and engineering infrastructure.
