Increased maritime shipping activity by larger ships is elevating the risk for maritime accidents and environmental impacts. Starting in 2004, these risks are being ameliorated by Automatic Identification System (AIS) technology. Similar to airplane transponders, AIS transmits a vessel's name, type, position, size, course, destination and speed several times a minute. This information is received,...
The main purpose to push the development towards autonomous maritime operations in shipping and offshore installations, is to increase the performance of maritime activities; by social benefits for staff or other related personal groups; by economic benefits when the ability to increase the cargo or effectuate better space allocation; by environmental benefits that's allow the ship operations to be...
It's midnight on the North Atlantic, where a massive container ship receives the latest weather report. There's a nasty storm brewing ahead. Quietly, the ship changes course and speed, to skirt the worst of it and ensure an on-time arrival at its destination. The ship's owners and the harbormaster at its next port of call are advised of the revised route. And as it nears shore, the giant ship must...
We live in an ever-changing environment where there is a vital need for persistent monitoring of human activities; whether it is for security, safety, economic or environmental purposes. Our oceans are no exception and may even be the region of our globe that is most at risk. Unbeknownst to many, there is limited visibility and awareness of maritime activity beyond 40-50 nautical miles from our coastline...
With number of ships increasing, the scale of ships being increasingly larger and anchorage ground being increasingly crowd, the accidents of dragging anchor occur more frequently in recent years. In order to improve the security of mooring ship and realize the intelligent monitoring of mooring ship, this paper reviewed the application of all kinds of navigation instruments used in the field of mooring...
Emergency Position Indicating Radio Beacons (EPIRBs), as an interface — offering services of Cospas-Sarsat worldwide plays an essential role in Search and Rescue mission. Regrettably, EPIRBs have a high rate of false activations which may cause — unnecessary expense of Search and Rescue activities. In this paper, — while analyzing the false alert rate and the cost on it, an approach towards improving...
Maritime patrol and environmental monitoring tasks, and so on, had attracted the attention of the maritime authorities by USV which instead of some traditional vessels by men control. According to the requirements of the development of the USV and its experimental inconvenience, setting up model ship experiment platform in the service of USV experiments demand, making model ship as its carrier, and...
Due to the importance of the marine resources, the limited sea routes are valuable for the marine transportation. With sensors deployed under the sea, the data of flow velocity are obtained via wireless communications. Based on the real historical data collected from Qinhuangdao port, which is one of the most important ports in the North China, the rules is attempted to be revealed with the data mining...
To increase competitiveness, reduce environmental impact, improve accessibility and enhance safety and preparedness in the Baltic region, the EU launched MONALISA project which is an e-Navigation solution to achieve intelligent sea route in the Baltic Sea. At first, this paper introduces the MONALISA project. Then it summarizes innovative idea and technology in MONALISA. In the end, based on the present...
Maritime communications are still strongly carried out by conventional means of terrestrial links via radio using MF to VHF bands, mainly after the introduction of systematization of digital selective callings. However, a large number of the communication procedures still rely on manual intervention, thus reducing their effectiveness and giving origin to errors such as false distress callings. The...
Grid is one of the most important information technologies in recently years, and its theory has been applied in a variety of industries. Based on grid management, the synergic mode has been established on the three levels (management, operation and support) of the maritime administration combined with three periods (before, in progress and after) of the marine accidents in China's coastal waters...
This paper describes a AIS-based model to assist the design of Ships' routeing system which provide useful insights about complex maritime transportation routes. The AIS analysis model mainly focuses on the transit traffic in the Channel. The AIS provides a method to analyze the vessel traffic density, meeting times and speed conditions in the Channels. An architecture of traffic stress model and...
The general scheme of monitoring point placement for health monitoring of dredger is presented based on analytic hierarchy process (AHP) in this paper, according to highly complexity and relevancy of power machinery of dredger. First, hierarchical structure model is established according to AHP. Secondly, evaluation factors based on failure modes, effects, and criticality analysis (FMECA) are analyzed...
There are many of distress vessels in marine to wait for succor. Marine search and rescue (SAR) is an important social responsibility and it is very urgent to improve marine SAR ability by peacetime training. However, conventional real ship practical training on the sea is expensive and the training circumstance differs from of real SAR circumstance which is very adverse. This paper brings forward...
In this paper, there are presented and discussed the issues regarding the perfection of the information services of the maritime navigation. Although the today developmentpsilas level of information and communications technology (ICT) allow to solve almost every hardware and software issue of information systems, nevertheless there exist very many issues of the maritime navigation information services...
In this paper the concept of providing safety and security in the Tricity sea harbors, in the context of the EURO 2012 was presented. Different aspect of monitoring and protection, including mechanical and sensor barriers (acoustic, magnetic, thermal, visual, optical (laser), mechanical etc.) was discussed. Moreover the underwater security systems, data collecting systems and data interfaces for communication...
