The phenomenon of international seaport administration is the subject of this book. As a Ph.D.-student at the Delft University of Technology (period 1993 - 1997) I had the opportunity to develop and exercise my hobby on a full time base. The result was a Ph.D.-dissertation which was defended in December 1997. Unfortunately, these research results were published in Dutch while the majority of the interviewees and employees in the world of international seaport administration are English speaking people. Both for the reason of high international relevance of the results I felt the necessity to get this Ph.D.-research translated and published in English. With the excellent help of my promotor Prof.dr. W.G.M. Salet I found Prof.dr. H. van der Wusten prepared to cover this study on international seaport administration in the Kluwer GeoJournal Library series. I thank Mr. Van der Wusten for giving me this opportunity. But also due to the outstanding help of my current employer 'Zeeland Seaports Authority' the funding for the translation became very quickly possible. I thank the Managing Director of Zeeland Seaports Authority, Mr. J.M.H.G. Philippen, and the Commercial Director, Capt. J. Verkiel, for their interest and wonderful help in getting this study translated. And of course my sincere thanks go to Katy Owen who actually made this dream come true.
