Methodology of creating a work schedule for dredging a port area

Since there is a tendency that new build vessels are increasing in size, dredging has become an important part of the development and maintenance strategy for ports serving the largest ships. The increase in the technical depth of vessels drives additional development of the entire port. However, the effectiveness of this type of project depends heavily on unrestricted traffic and uninterrupted operation of the terminal. This paper presents a modelling of various type of dredging activities in ports based on an existing work schedule. A tool used to queue work activities with a vacation was used in this effort. The methodology of creating a dredging time schedule in the port area depended mainly on disentangling interference caused by the ship traffic and dredgers trying to work at the same time.
