As the development of ship building technologies, ships have been becoming larger and larger. a result, existing ports waterways can not meet requirements safe navigation, berthing unberthing operations large ships. In order to ensure for ships, wharf need be rebuilt, also it is necessary check whether rebuilt navigation needs. this paper, handling simulator used simulate pier. This paper estab...

This paper is an empirical attempt verifying the interplay between political change, fleet nationality, and the evolution of shipping networks. North Korea offers a good example of a socialist maritime country that experienced much contrasted geopolitical contexts during the last two decades. A database of vessel movements between North Korean ports and other ports is analyzed. Main results sho...

Ports can be defined as the main centers of maritime transportation and trade, which provide continuity international trade well loading unloading services to ships. As a result globalizing world, importance ports has continued increase day by because made faster more efficiently. The fact that are located at such critical point, increasing transaction volume, development environmentally sensit...

This paper presents a new application of the Decoupling Control to automatically control large ships in harbour areas. A multi-term non-linear mathematical model is adopted to express ships’ manoeuvring motions. The method for designing the automatic control system is briefly described. Computer simulation results for a Very Large Crude Carriage (VLCC) on a simple berthing manoeuvre are given t...

On-Orbit Servicing (OOS) is not only an option for the repair and the upgrade of space assets that suffer from technical failures but might also be a promising business case, e.g. extending the lifetime of geostationary communication satellites. Another example of robotic service operations would be the servicing of low-earth orbit satellites. Currently, this expertise is being developed at GSO...
