Maritime Navigation

Enhancements in shipboard automation offer the prospect of crew size reductions for navigation tasks. This work was concerned with comparing the structure of navigation tasks using paper charts with the same tasks accomplished using an electronic chart display information system (ECDIS). Voyage planning with paper charts is based on drawing specific voyage segments, measuring distances between waypoints, and annotating the chart with voyage specific information. These tasks change substantially with electronic charts, particularly in terms of how the task is accomplished. Similarly, the manual activities of track keeping are reduced, but the need for a continuous record maintains the use of the paper chart. For both navigation tasks, there is less ability to visualize geographic features continuously with electronic charts because of the keyhole effect created by a CRT display. It is concluded that the design of automated navigation aids should be based not only on the informational aspects of task performance, but also the functional means by which navigators carry out their tasks with conventional technologies such as paper charts.

Taking Action

In this paper, authors suggest an improvement in the electronic chart display and information system handling. Electronic nautical charts provide significant benefits to maritime navigation as a real time navigation system and all updates are important. This paper analyses the electronic chart use experiences on board ships. A questionnaire and survey were used so as to ascertain and corroborate the existing problems with corrections and maintenance of electronic charts on ships, and reliability of the systems was calculated. The survey results have shown that ship’s officers had serious problems with ECDIS systems which were difficult to solve during ship’s operation. A survey was done which showed that a significant percentage of the surveyed bridge officers and captains had problems with ECDIS system operation, such as operation stoppage due to different reasons. They did not always report failures of these systems while having continued to operate ECDIS. The reliability of those systems was also calculated and it resulted 0.916 or 91.6%. Compared to results of previous similar researches done by other scientists, the results of this research show an improvement in the ECDIS handling. It was concluded that a proper action was needed toward finding the solution to the future chart corrections procedure through remote monitoring and maintenance. The study results emphasized that taking action was necessary in the interest of safety protection on ships, with particular attention to be paid to better safety of navigation, of life, and of potential environmental pollution due to this type of information system failures. The results obtained by this study represent a good starting point for future researches in the field.

New System

The AN/SSN-6 Navigation Sensor System Interface (NAVSSI) Project is a new system being designed with two primary objectives; to serve as the central distribution computer for navigation data to shipboard combat/weapon systems and to serve as the electronic chart display and information system (ECDIS). The NAVSSI will operate the digital nautical chart (DNC) database being developed by the Defense Mapping Agency (DMA). Our goal is for the digital nautical chart to replace the paper chart as a legal means of ownship navigation plotting. This paper will introduce the project and will primarily explore the use of digital nautical charts for ownship navigation with NAVSSI.

Selection Of

Today's methods of plotting courses and selecting sailing routes and turn points in maritime navigation are still largely based on subjective assessment of the master or the officer in charge. This results in a great variety of course distribution and, accordingly, in various ship movements. Modern electronic aids, in particular ECDIS (Electronic Chart Display and Information System) can significantly facilitate maritime voyage planning, course plotting, selection of turning points, etc. In addition to displaying electronic charts, the specific feature of these systems is that they facilitate route planning, supervision of ship movements, data recording, database search, alarm setting, etc. However, these systems do not yet provide automatic selection of courses on user's request in a standardised form. Therefore, in most cases, the routes and turn points are selected empirically or because they have been previously defined and used. This paper shows the drawbacks of the existing methods of selecting routes and plotting courses in maritime navigation and gives recommendations how to improve them.

Abstract—The need for information system development in a company is a basic requirement that must be met by each company in order to run its business processes properly. This is the basic key in a company in order to provide maximum results to find as many profits or profits. Application development or requirements in the application also provide speed for employees to carry out their activities to work properly and optimally. The development of the era requires that companies must be productive and have innovations so that the business wheel of the company can run well. This is based on the development of technology that is so fast that it requires special expertise in its application. This research is expected to be able to help some problems that exist in a company. Where its application can make it easier for employees to carry out their respective duties and roles in order to maximize their potential. For companies, the application of this application can accommodate the company's business wheels so that they can be properly and correctly documented .   Keywords : Systems, Information, Applications
