The paper presents the processing of EGNOS integrity data received either directly from the satellite network or the Sisnet internet relay. Relationship between the individual frames in EGNOS messages has been described. Usefulness of these data was indicated by the three examples. In the first example data form EGNOS was used to compare integrity parameters and the calculated position error. In further examples the simulated position with error and calculated integrity parameters were implemented together. The results were presented in two ways: with use of dedicated program which presents only ship contours (the one not covering GNSS uncertainty and the one covering this uncertainty called Marine Vessel Protection Area) and as a layer in existing ECDIS.

The basic idea of this paper is to motivate teachers/instructors of maritime schools and colleges to create interesting and engaging screencasts for teaching students (future seafarers) ECDIS basis, by using new contemporary media and didactical solutions. Camtasia Studio has been proposed as suitable applied software for doing so. It is a multi-media, user-friendly environment, providing the customers with the variety of possibilities for editing PowerPoint presentations with the introduction of audio, video and different animations, in order to make teaching/learning content more interesting and to point out the most important issues. It allows computer screen video capturing, and adding of audio and numerous animated effects to it, as well as augmenting video recordings into the Camtasia project(s). Even though the proposed software tool possesses a broad palette of advanced features for recording and editing “lively” and edifying recordings, within this paper only brief descriptions of “reviving” classical PowerPoint presentations, taking the screen captures over Transas demo ECDIS software, and their editing is presented. Several examples of instructional recordings concerning ECDIS operational basis, and possibility of students’ self-evaluation have been given, too.

The current discussion on the future of electronic navigation is focusing on the expansion of ECDIS by integrating additional data streams, like AIS or real-time tide information. While this are important aspects, which will be touched on in the paper, it is important to note that the ENC data layer is the necessary data layer to enable advanced data display. The current focus on ENC production has a limited view on coverage within scale bands and on datum code. While this allows concentrated efforts to produce the necessary country coverage to meet the timeframe of the IMO ECDIS mandate, future mariners will require a more solid basis of chart data for their electronic naviga-tion needs. The IMO e-Navigation discussion and the discussions in related the IALA e-Navigation Commit-tee are starting to join efforts with the new IHO S-100 and S-101 standards as well as the developing S-10X series of standards. The Hydrographic community needs to take that in account when preparing for the future of electronic navigation to increase safety of navigation in a rapidly changing environment with larger ships and more traffic in areas with specific navigational challenges. The paper will focus on the following topics: – The ENC data layer as the basis of electronic navigation, – Closing gaps and overlaps in ENC coverage by adjusting cell boundaries, – Moving from a cell based data structure to a seamless database structure, – Integration of Scale-Independent and Scale-Dependent objects, – Adaption of harmonized and flexible data models – an S-10X outlook, – Enabling integration of advanced data streams – an e-NAV outlook.

Implementation of the Marine Electronic Highway (MEH) project in Straits of Malacca and Singapore will complement the efforts taken by Malaysia, Indonesia and Singapore as littoral states in enhancing safety of navigation and the prevention and control of marine pollution in the Straits. The Project Steering Committee meetings of the MEH indicate that, the progress in the implementation of its activities is in the midst of many challenging conditions. The efforts is a testament that the littoral states are working together to ensure the implementation of this project is running smoothly since the donor agencies, user States and the maritime industry have great expectations on its success. The MEH project consists of four important components such as Hydrographic Survey and Electronic Navigational Charts (ENCs) production, Environment Marine Information Overlays, Baseline Survey and Information Technology Structure. This paper will address the current status of the implementation of the four key components highlighting the development of ENCs as a vital tool to sustain the safety of navigation along the straits. The discussion in this paper is based on some preliminary survey findings and from reports of the Project Steering Committee meetings.

This paper presents the results from a recent study on the coverage of Electronic Navigational Charts (ENC). Global traffic datahas been evaluated in relation to the coverage of ENC and eleven specific ship routes, representative for global merchant shipping, have been analyzed in further detail. Overall, the ENC coverage was found to be extensive, with 82 – 94% coverage for SOLAS ships, and 28 – 100% coverage along selected routes. Furthermore, it has been demonstrated how the coverage of ENCs could be taken into account when assessing the effect of ECDIS for safer ship navigation and associated cost effectiveness.

E-navigation is, at the moment, a catchall phrase for a concept of bringing existing and new technology together to improve safety of navigation, commercial efficiency and security. The challenge for the industry working through the IMO will be to produce a unified strategy for this integration and then (and only then) to develop specific systems to meet the needs. This is no small feat! Chart data and systems need to be brought to an agreeable standard; position fixing systems need to be of high integrity; and communication systems need to be establishing that meet the needs of e-navigation with agreed technology, protocols and payment plans. This all needs to be achieved with an acceptable cost/benefit balance.

Production of ENCs is based on the theory of multiscale data management (usage bands) and multiple representation of ENC data, controlled by scale minimum (SCAMIN) attributes. This paper presents a solution to the problem of multiscale data management and multiple representation as a part of ENC data production for archipelagic sea areas, using the east coast of the Middle Adriatic Sea area as a typical example. This study is based on a long-standing experience in the production of paper charts and recently ENC production for eastern coast of the Adriatic Sea, which is believed to be the second largest archipelagic area in the Mediterranean. A new method of using SCAMIN attributes for archipelagic seas was proposed, based on Canadian method. Also, a new usage band scale range, compilation scale (twice the chart scale) for all navigational purposes and method of using SCAMIN attributes for archipelagic seas are proposed.

ECDIS as a real-time navigation system integrating variety of charts and navigation-related information that replaces the usage of paper chart. Nowadays, ECDIS usage is getting more recognized as being used for both navigation and collision avoidance tasks. In this consideration, Turkish ship management companies are at the right cornerstone to take a decision for the substitution of paper chart with ECDIS. Cost factor has a significant role during the selection process and it needs to be optimized with cost-benefit ratios of each alternative. This study originally tends to describe decision making process with alternative solutions that could be applied to ship’s bridge operations. By utilizing multi-criteria decision making model, it is aimed to facilitate the selection of two alternatives with “Analytic Hierarchy Process (AHP)”. Consequently quantifying the influence of related factors to the selection of two alternatives for Turkish management companies, a hierarchical analysis framework is developed and applied by AHP method.

An Electronic Chart Display and Information System (ECDIS) is a highly advanced and powerful navigational aid, specifically designed for enhancing safety at sea. With the growing adoption of ECDIS (ECS) there is an increasing number of Officers who need to be trained in its use. Given the flexibility of the labor market, it is highly likely that Officers may arrive onboard a ship without experience or training. To adequately train responsible personnel, Transas has developed specialized ECDIS Operator Training Equipment. In the papers Jochen Rudolph focuses on the requirements set out by existing IMO regulations for ECDIS operators and outlines the distinctive features of the ECDIS Operator Training.
