Great Sense

There is a great sense of movement and progress in navigation today. The excitement lies in the ability to do things which were not possible with traditional media or at best were difficult and time-consuming to achieve. So this paper is not about the desirability nor the timescale of the ECDIS (Electronic Chart and Display Information System) replacing paper charts for primary navigation. It is about the flexibility and creative power opened up by new technology.

Electronic Chart

Electronic Chart  Display And Information System (ECDIS) adalah suatu alat navigasi berupa peta elektronik sesuai persyaratan peta terbaru konvensi SOLAS 1974 V/20 yang dapat diintegrasikan dengan ala-alat navigasi lainnya sehingga diperoleh posisi dan informasi navigasi lain untuk para mualim melakukan perencanaan pelayaran serta monitoring rute pelayaran. Tujuan dari penelitian ini adalah untuk meningkatkan pengetahuan para Mualim dalam penggunaan ECDIS agar mencapai keselamatan dalam berlayar. Metode yang digunakan dalam penelitian ini adalah metode kualitatif yang mendeskripsikan melalui kata-kata dan bahasa dalam menjelaskan masalah atau fenomena yang  diteliti. Untuk menjabarkan masalah digunakan jenis penelitian deskriptif yaitu dengan mendeskripsikan suatu gejala, peristiwa dan kejadian yang terjadi. Pengumpulan data dilakukan melalui wawancara, dan observasi dalam melakukan penelitian, studi pustaka dan studi dokumentasi. Hasil penelitian ini menunjukkan bahwa para mualim belum maksimal dalam penggunaan ECDIS sehingga diperlukan peningkatan pemahaman dan pengetahuan dalam menggunakan ECDIS agar keselamatan bisa diutamakan saat berlayar.

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.

In this paper, equations are established to solve problems of Rhumb Line Sailing (RLS) on an oblate spheroid. Solutions are provided for both the inverse problem and the direct problem, thereby providing a complete solution to RLS. Development of these solutions was achieved in part by means of computer based symbolic algebra. The inverse solution described attains a high degree of accuracy for distance and azimuth. The direct solution has been obtained from a solution for latitude in terms of distance derived with the introduction of an inverse series expansion of meridian arc-length via the rectifying latitude. Also, a series to determine latitude at any longitude has been derived via the conformal latitude. This was achieved through application of Hermite's Interpolation Scheme or the Lagrange Inversion Theorem. Numerical examples show that the algorithms are very accurate and that the differences between original data and recovered data after applying the inverse or direct solution of RLS to recover the data calculated by the direct or inverse solution are very small. It reveals that the algorithms provided here are suitable for programming implementation and can be applied in the areas of maritime routing and cartographical computation in Graphical Information System (GIS) and Electronic Chart Display and Information System (ECDIS) environments.

Automatic route design will help to develop electronic chart intelligence, hence to improve safety, economy and reliability of the route. In the paper rasterizing charts are used to expressed the navigation environment of the ship and the modified A* algorithm is used to compute the near optimum trajectory of a ship in given environment based on electronic chart dispiay and information system (ECDIS). By tracing Safety contours, computing obstacle areas and taking into account certain boundaries of the manoeuvring region, the problem of avoiding collisions at sea was reduced to optimization task with static constrains. Simulation using MATLAB is conducted to verify the proposed ship path planning method. The good results show the promise of this method for ship at sea.

Test Scenarios

Electronic Chart Display and Information Systems (ECDIS) technology has recently emerged as a promising aid to maritime navigational safety and operational efficiency. ECDIS is likely to have multiple effects on the tasks bridge personnel must perform. However, careful consideration must be given to safety in adopting this new technology. A shiphandling simulator-based evaluation of some human factors aspects of the use of ECDIS is presented. The issues discussed include the effect on navigational safety and workload as a result of introducing ECDIS to the bridge, and the mariner's preference for and use of chart information and navigational data. Experienced mariners each made multiple port arrivals and departures as the lone watchstander on the bridge: navigating a planned route, responding to harbor traffic, and managing the preparations for arrival or departure. During “baseline” transits, conventional methods were available to the mariner. During the test scenarios, one of two prototype ECDIS systems was also added to the bridge. Under certain conditions, ECDIS reduced the mariner's workload for navigation. In addition, ECDIS showed a potential to increase safety as measured by a smaller cross-track distance from the planned route and by a larger proportion of time available to devote to collision avoidance and “look out”.

With rapid development of the geographic information system technique, the electronic chart has come into being and is more and more mature. The electronic chart can provide the accurate and detailed information about the ocean environment, including the depth of water, situation of the seabed, distance from the shore, position, orientation and velocity of the ship, and other useful information. This paper first gives some introduction about the electronic chart. After analyzing the characteristics of the electronic chart, the application of the electronic chart in ocean navigation is provided. Finally the existing problem of the electronic chart and its future development trend are also discussed.
