The study is to give suggestions on future developments of the Eemshaven. The port locates on the north coastline of the Netherlands, opened in 1973 as an indutrial port. It is in the charge of Groningen Seaports in the municipality of Eemsmond. By rail, road and inland waterways, the port connects to the rest of the Netherlands, Germany and other west European countries directly or indirectly. Now most port activities happen in the west part, most of which are shipping and warehousing related. The east part will soon be occupied by four power plants, namely Energy Valley. The construction of Energy Valley is considered as the most important development in the coming five years. The port has been through a rough time. Many nice ideas failed for all kinds of reasons. The developments in the past show that the activities will not be successful in the Eemshaven unless certain scale is reached. The connections with local industries and the help of the governments make the activities more likely to be successful, while enterpreneurship is another important factor. Compared to the neighbor ports, the Eemshaven has very low throughput. Hinterland connections, port facilties and especially the relation with local industries are not as good as the neighbor ports. Porter’s Diamond Model shows the Northern Netherlands is not a competitive region, compared to the nearby areas. Many trational strong sectors are no longer dominant. That means the region cannot give many supports for local seaports. The positive factors of the Eemshaven include space and energy supply, competitive price, easy acess to gas pipelines and cables. Lack of hinterland support is a serious problem of the Eemshaven. Besides, underdeveloped labor market, living circumstances, limited logistics facilities and shipping routes, lack of comprehensive development approach are negative factors of the Eemshaven as well. The Wadden Sea protected area is always one of the concerns, which gives limitations of the potential activities in the Eemshaven. Two scenarios are set for different situations. The first scenario focuses on a future 5-10 years, no port expansion is expected. The suggestions are developing energy related industries and improve landside accessbitlies. The scenario foresees a big expansion of the port, in the coming 20-30 years. The industries more than energy are expected to form a cluster in the port area. Upgrading the scope onto a regional level, having integrated plans and measures to avoid port competitions are suggested in this scenario. Energy consuming industries, fuel related activities, environment protection, clean energy and their related industries are chosen for scenario 1. Food industries and oterh agriculture related industries, chemical industries, materials, recycling, energy related industries , shipping and warehousing are considered as the suitable sectors for the port industry cluster in the second scenario. Eleven experts give their comments on the study. Most of the experts react positively to the study. Half of them think scenario 1 is more likely to be the future for the Eemshaven, which would be done in 10 years without expansion. The others do believe the aggressive scenario may partly happen. According to the experts, the most promising sectors are renewable energy and bio-based industries. Recycling can be very interesting as well. Shipping activities are considered to be the most difficult one to develop. To set the renewable energy, bio-based indstries and other energy related industries as a main development line, and to look for other opportunites out of this line but may have very positive economic impacts is a further remark on the study, after the consultation of the experts.
