The subject of this research are administrative processes related to a ship’s arrival to seaports, typically attributed to elevated levels of cost of labour required to complete the related administrative tasks. In the previous phases of the research, an average expected cost of the administrative labour cost in traditional seaport clusters in Croatia was identified and quantified on an hourly basis. This research continues in its aim by using the results of the previous research as a starting point, and proposes a reengineered simulation model of the administrative process. The main hypothesis is that the usage of such a new model will result in a measurable decrease of the required labour cost. The main hypothesis is confirmed by simulations and calculations of the labour cost reduction
