Assembly personnel in one-of-a-kind shipbuilding dedicate only a small proportion of their on-site time to value-adding activities, with non-productive tasks consuming up to 78% of their working hours. Considerable effort is expended on material procurement, information retrieval, and preparation of work sites. In addition, evolving customer requirements and internal planning deviations lead to frequent design changes in the production phase, resulting in substantial rework and elevated scrap rates. This is particularly evident for pipes, fittings, and related accessories, which are integral to numerous onboard systems throughout the vessel. Coordinating their delivery through traditional sequential scheduling results in redundant handling due to time-consuming retrieval processes for pre-manufactured parts by suppliers, and complex on-site material provision by shipyard logistics. A promising approach to overcome these challenges is to schedule frequent, small-batch deliveries in line with construction progress. While synchronizing supplier production and delivery with the assembly progress has proven to be an effective solution in automotive serial production, its application in one-of-a-kind shipbuilding is severely limited by the poor availability and accessibility of up-to-date information. To bridge this gap, this paper examines the picking and packing of installation-ready units by suppliers through the systematic use of prototype digital assistance systems integrated with a consistent database. Ultimately, this approach aims to significantly enhance the productivity of shipyard assembly workers and accelerate overall ship delivery schedules.
