Financial Modelling and Port Dredging Analysis

The purpose of this study is to analyse the financial aspects of dredging for ports and harbours that need to maintain ship accessibility. The volume of sediment produced is usually significant in size and in expenses to manage. This paper develops a financial modelling and analysis for the management of maritime sediments using a financial model. This model can be used as a decision-making support tool by shareholders in ports, consulting companies and observers. To achieve this, a decision support tool has been developed and almost every available data has been used from a wide range of different countries. This model analyses a wide range of dredging production processes until the final usage. Required inputs include sediment characteristics, logistics data, financial scale of dredging in national level and direct expenses. This paper explains the potential of the decision support tool for financially evaluating a wide variety of dredging management options, as well as providing valuable information for the optimal management, and provides a comparison between traditional options and potentially useful scenarios.
