Maritime management encompasses the employment and manipulation of human resources, financial resources, technological resources and natural resources that relate to the sea, maritime navigation, shipping, port development and coastal protection. It contributes to the economic growth, price stability, transportation of cargoes and passengers, and business activities of shipping organizations. The efficient management of resources, operations and activities relies on a modern marine information system (MIS) whose information is provided by geomatics engineers and IT professionals, among others. This paper first introduces the role of the geomatics engineer as geodesist, engineering surveyor, land boundary surveyor, cartographer, hydrographer, photogrammetrist and geographic information system (GIS) engineer since all these fields are related to maritime trade, supply chains and development of ports and airports. It then describes the principal components of a web-based MIS and the important role of geomatics engineers in surveying data. This includes collecting data from electronic nautical charts (ENC) and raster nautical charts (RNC), by applying high resolution light detection and ranging (LIDAR), satellite platform sensors and GIS. 相似文献

The International Maritime Organization (IMO) has encouraged its member countries to introduce Formal Safety Assessment (FSA) for ship operations since the end of the last century. FSA can be used through certain formal assessing steps to generate effective recommendations and cautions to control marine risks and improve the safety of ships. On the basis of the brief introduction of FSA, this paper describes the ideas of applying FSA to the prevention of human error in ship operations. It especially discusses the investigation and analysis of the information and data using navigation simulators and puts forward some suggestions for the introduction and development of the FSA research work for safer ship operations. 相似文献

Innovations in information technology, satellite navigation and hydrography are making it technically possible for commercial ships, run by very small crews, to be navigated in the world's seas and oceans with positional accuracies measured in tens of metres. If shipping lines do make the necessary investment in technological hardware, training, operational readjustments and data acquisition, and are also allowed to exploit the full potential of GPS, it will not be surprising if they then expect the ports to provide levels of information that allow the ships to exploit their new capabilities right up to the berth. Ports wishing to hold or improve their perceived service quality in the competitive port league will need to consider whether, and how, they can meet the shipping lines' requirements.
The introduction of strict product liability law adds a new dimension to the assessment of commercial risk in the various technological possibilities available to the ports. The possible costs involved in cases where third party data processors, software producers and electronic chart hardware manufacturers all stand between the port's data output and the user's perception and use of it, in a completely ephemeral form on a screen, need to be considered carefully. Simpler forms of data transmission, such as via traffic advice broadcast or by pilots in person may be seen as the more prudent choice in the five to ten year horizon. 相似文献

船舶航行实验是船舶完工以后,验收时按规定进行交船试验的重要部分。传统的试验方法是通过GPS定位、人工测量和记录,再进行分析,耗费许多人力、物力。本试验方法是在GPS定位技术、电子海图技术、计算机处理技术基础上设计的新型试验系统。在航行试验时由GPS获取实时的位置信息,将位置信息显示到电子海图上,另外由数据库存储试验数据,试验结束时由计算机自动处理得出试验结果并可打印。使用情况表明该系统可以准确、方便地完成航行试验,试验结束后还可以离线分析,为未来的船舶设计积累相关的资料。 相似文献

In 2016, the world shipping fleet grew by 3.5%. Even if the annual growth rate remains at its lowest since 2013, the global situation is still in overcapacity (UNCTAD 2016). Ninety percent of global trade, by volume, is done by sea. Monitoring this fleet helps with vessel navigation, informing to help avoid critical situations such as collisions, accidents leading to oil pollution, grounding, or ships in distress, but also because traffic management in congested areas is essential. For system wide management, in regions such as MPAs (marine protected areas), conservation is the key factor, and movements can be monitored and analyzed in order to determine illegal or suspicious activities, or in order to limit and/or divert traffic, to mitigate the risks to species subject to protection. It is among these efforts that the automatic identification system (AIS) can play a key role. Since 2004, this VHF transceiver-based reporting system, imposed by the International Maritime Organization (IMO), has shifted from a traditional vessel identification device to a tool used in a wide variety of applications. The most common uses are safety and security; these issues are quite visible in the media and may touch more people on a global scale (e.g., piracy, oil spills). Over the years, AIS has become, especially with the emergence of the satellite-based capture of the signal in 2011, a widely used tool for developing applications such as fisheries monitoring, marine conservation, air pollution forecasting and modeling, ballast water monitoring, invasive species transport, and many more. In this paper, we propose to review the peer-reviewed publications related to the uses and applications of the AIS. 相似文献
