This paper describes on the evaluation and management of work process in suction hopper dredger and grab bucket dredger as an application of a PC-based ECDIS system. The dynamic tracking of dredging bucket and the data logging of grab dredging information were performed by using the grab dredging vessel "Kunwoong G-18". The position and route tracking of the dredger moving toward the ocean dumping site of dredged material was performed by using the hopper dredging vessel "Samyang-7". The evaluation of wok process in the dredging field, for grab dredger, was continuously carried out on January to May, 2006, in Incheon Hang and for hopper dredger, on July to December, 2003, in Busan Hang, Korea. The dredging information, such as dredger's position, heading, dredging depth and route track which was individually time stamped during the dredging operation, was automatically processed in real-time on the ECDIS and displayed simultaneously on the S-57 ENC chart. From these results, we conclude that the ECDIS system can be applied as a tool in order to manage the work process during the dredging operation, and also in order to generate the factual record of the dredging activities that is sufficient for dredging inspector to accurately evaluate the contract performance even in the absence of a full-time onboard inspector.

There are Marine equipment, electronic chart display and information system(ECDIS) which can make a voyage using sounding machine in vessel. ECDIS current systems do not have a unified protocol between devices installed in the sea. But protocols between devices are not unified in this system. When the devices installed on the sea are replaced, communication environment should be changed. It is costly to dismantle and withdraw them so they are used without change. Due to these problems, a system being sold in the market consists of ENC system and another system receiving data seperately. In this paper, to solve these problems, it is designed to integrate and support various protocols within a system using data transmission and receiving function and streaming so that ENC can be seen via mobile as well.

Nowadays, as IT industry is being developed, many studies are in progress in the areas of user interface (UI) and user experience (UX) and interest in the icons related to these areas are rising accordingly. IT developments have also influenced the vessel sector promoting the development of navigation equipment and systems utilizing IT. However, due to complicated functions of navigation equipment and systems, concerns have been noted about the increased cognitive burden on officers, along with the need for researches on reducing such burden. This study, therefore, was conducted focusing on the design of icons that will reduce cognitive burden on officers when using a typical navigation equipment such as ECDIS(Electric Chart Display and Information System). Based on a survey conducted with experts who have rich experiences in navigation and are currently teaching ECDIS in universities, the present study identified the functions of ECDIS, for which icons should be designed. Accordingly, suitable icons for ECDIS were designed and their effects were evaluated. It is expected that the results of this study will be used as basic data for the design of icons for other navigation equipment in the future.

ECDIS(Electronic Chart Display and Information System 전자해도정보시스템)와 같이 진보된 IT 기술을 적용한 항해장비는 단순히 항해의 목적으로 사용하는 것 이상으로, 해양환경의 보호와 감시에 응용하는 등의 방법으로 그 활용범위를 직접적이고 적극적으로 확대할 수 있다. 종이해도와 달리, ECDIS는 '시간'이라는 4차원적 요소를 도입함으로써 동적시스템(Dynamic System)으로 전환이 용이하다. 이것은 조석, 조류, 바람과 파도와 같은 시간변수(Time Variables) 데이터를 적용함으로써 가능하다. 이 시간변수들을 어군이동위치, 계절변화에 따른 해저지형, ballast water의 취수를 위한 청수지역 등과 함께 활용을 한다면, green ECDIS를 활용한 green navigation은 현실화가 가능하다. 이에 따라 해상종사자의 환경인식은 뚜렷하게 그리고 유용하게 증가할 것이다. 본 논문에서는 green ECDIS의 개념과 모형의 설계 그리고 프로토타입의 개발을 제안하고자 한다.

IT 발전과 함께 디스플레이가 탑재된 제품들을 주변에서 쉽게 찾아볼 수 있다. 제품의 디스플레이는 현재 상태 및 위험도 등 다양한 정보를 시각적으로 사용자에게 제공하는 중요한 역할을 하고 있다. 이로 인하여 시각적으로 사용자에게 좀 더 직관적이고 효율적으로 정보를 제공하는 방법에 대하여 많은 연구들이 진행되고 있으며, GUI 분야의 관심도 높아지고 있다. 항해분야에서 디스플레이가 포함된 항해장비는 RADAR, ECDIS, ODD 등 다양한 종류가 존재하며, 그 중에서 ECDIS가 가장 많은 시각적인 정보를 제공하고 있다. 이처럼 ECDIS는 항해사들에게 시각적으로 다양한 정보를 제공하는 중요한 장비로써 본 연구에서는 기존의 ECDIS의 요구사항을 조사하며, HCD를 고려하여 개선된 ECDIS 장비의 작업 수행도를 평가하였다.

On the advent of digital era, ECDIS has emerged as a new navigation aid that should result in significant benefits to safe navigation. More than simply a graphics display, ECDIS is a new concept navigation system capable of providing integrated information of geographical and texual data. As an official vector data for ECDIS, ENC consists of spatial and feature data to describe objects in form of points, lines and areas. IHO published International Standards for ENC, such as S-52(Specification for Chart Content and Display Aspects of ECDIS) and S-57(IHO Transfer Standard for Digital Hydrographic Data). This paper deals with the implementation of an ENC representation system which meets S-52 presentation specification and S-57 transfer standards by analyzing S-57 data structures and converting them to an appropriate internal data structures and representing them onto screen adopting S-52 presentation specification.

IMO adopt the revision of SOLAS convention on requirement systems for ECDIS and considered an ECDIS as the major system for E-Navigation strategy on marine transportation safety and marine environment protection. ENC(Electronic Navigational Chart) as base map of ECDIS is considered as a principal information infrastructure that is essential for navigation tasks. Though ECDIS has many advantages, it's almost impossible for the mariner to recognize the displayed information because of intense display of objects so called the clutter. In this paper, the current status and international standards on SCAMIN((Minimum Scale) attribute have been investigated. Also improvement of SCAMIN attribute of ENCs and grouping method for the sounding values was proposed.

The main reason of marine casualties is the human error in respect of ship's operation. The human error of officers in charge of a navigational watch is related to their abilities to handle of navigational equipment. Navigational devices play a key role to help officers decide what to do for safe navigation. Thus, the abilities to handle of navigational equipment mean not only operation of devices but also entire understanding of the system such as interpretation of information obtained from devices, appropriate use of information considering navigational circumstance. Qualification of seafarers is in accordance with STCW and detailed training courses for their qualification are provided by IMO model course series. Recently, ships engaged on international voyages shall be fitted with an ECDIS not later than the first survey on or after 1 July 2018. As increasing use of ECDIS on ships, marine casualties related to ECDIS are on the rise. The primary causes of the accidents are lacking understanding of ECDIS system, wrong presentation of information on display, wrong safety setting by seafarers who use ECDIS, using small-scale chart and missing charts update. As a result of these primary causes, some problems like wrong route planning and use of limited or omitted information occur. It could be happening by inappropriate seafarers' training which is not sufficient to support improving abilities of officers to handle navigational equipment. For efficient training, it is need to develop training courses. Applying full mission simulation system to seafarers' training courses with case studies and best practices which are well-constructed scenarios based on true marine casualties can increase the effect of training. To use the simulation system, it is possible that seafarers are trained under condition that closely resemble real situation. It should be considered that IMO model course be revised depending on the level of seafarers also. It could be helpful for increasing seafarers' abilities of equipment operation in place of accumulation of experience spending much time. In the short term, effort of training courses improvement for seafarers is needed and long term, it should be tried to provide stable system and services relate to ECDIS.
