The basic principle of the Port activity application is that port actors share their estimated and actual times regarding certain states in the port call process as a minimum set of data. The information sharing is to support collaborative decision making and improving information exchange between port actors, hinterland operators and ships. A large number of phone calls and emails between port actors will be reduced to a minimum with Port activity application system adding to time savings in the movement of goods. The exchange of information will avoid bottlenecks that occur in the information flow today.
