ENThe necessity to get over water obstacles, growing cargo flows in the world; profitableness of high sea transport and other factors more and more are raise the importance of the ports. The port, as a logistic knot, play in the entire transport system the role of a joining chain. It joins maritime transport with the road and railway transport. The integration of Lithuania transport to European network and interstate corridors' crossing Lithuanian territory are investigated questions in this article. There's discussed condition of world shipping and tendencies towards the development. Also mentioned growth of fleet, increase movement of containers and general cargo flow and decrease of shipping tariffs. So all these questions raises the necessity of effective port administration, while planning rational technological operations in a port terminal and strive to decrease the expenditures of load and administration. First of all it's necessary to improve technologies and administration systems of information, while striving for better administration of growing movement of cargo flows. The scheme ofport terminal data movement system, which could greatly raise the effectiveness of port work, is shown in the article. The loads' dynamic of East Baltic ports also is investigated in the article. Lots of attention is given to the port characteristic, structure, infrastructure, and aspects of expansion of Klaipeda for the port position among other ports. There are described port users and the movement questions of trans-shipped cargo flow (1997-2000).The attention is given to the largest seaport cargo company of Klaipeda "Klasco" and other smaller cargo companies' activity. Common competitive growth aspects of ports' and port of Klaipeda are been discussed. The volume of load during 1998-2000 in ports of East Baltic is presented: Klaipeda, Latvia, Estonia, Kaliningrad, and St. Petersburg. There's a presumption that container conveyance through East Baltic countries is perspective and the intensity of trans-shipped containers and other flows should increase. While making canals of information and communication among the ports of all the East Baltic countries and of separate ports the attention is turned to perspective of developing unified information systems.
