When it is applied in maritime supervision, such as maritime patrol, sea cruise, investigation and emergency response, maritime search and rescue, navigation channel measurement, monitoring and inspection of the oil and sewage spills from ships at sea, it can effectively expand the uses of monitoring sea areas, reduce the phenomenon of illegal use of sea, which can improve modernization construction in maritime supervision. According to the UAV （unmanned aerial vehicle） development and application, this paper explores the advantages of the UAV application in maritime adminstration, as well as the characteristics of maritime adminstration, put forward some countermeasures and suggestions of UAV applied in maritime adminstration.展开更多

The high voltage power supply (10 kV/50 Hz/2 000 kVA) for the quay cranes is used for the power input of the system, after frequency and voltage converting (450 V/60 Hz), then putting out and supplying to vessel. This system is flexible with positive effect on energy-saving and emission reduction; besides, there's no requirement of civil reconstruction to container terminals, which is suitable for the busy ports in China.展开更多
