  • After full implementation of the GMDSS on February 1, 1999, non GMDSS equipped vessels may experience difficulty in establishing communications with vessels complying with the GMDSS. These difficulties are associated with the differences between the automated equipment required in the GMDSSand the non-automated equipment typicaly carried on small vessels. The purpose of this paper is to describe the IMO activities on the application of the GMDSS to non-SOLAS Convention ships both from a radiocommunication and a SAR point of view, and the national GMDSS implementation programme for non-SOLAS vessels. There are no differentiation between SOLAS ships and non-SOLAS vessels complying with the GMDSS, but they have to comply with the GMDSS according to the trading area A1, A2, A3 and A4. Canadian commercial vessels not subjects to SOLAS , will be required to comply with the GMDSS. Carriage requirements are being developed in consultation with the marine industry. The vessels not subject to SOLAS will not be required to carry GMDSS equipment, however, it is recommeded they fit for the GMDSS as applicable to their area of operation in many countries. Some recommednations are made to implement the GMDSS for non-SOLAS vessels in Korea.

  • An international study on Class B AIS for Non-SOLAS vessels is in progress through IMO and IEC. The IEC issued CDV(Committee Draft for Vote) on March 3, 2005, as IEC 62287, which includes operational and performance requirements, methods of test and required test results about Class B AIS. In this paper, we proposed the method of making Class B AIS properly onboard. This research deals with the problems of introducing Class B AIS which is properly applicable on small fishing vessels as well as domestic Non-SOLAS vessels. Moreover, several technical considerations were suggested to develop a national technical standards for Class B AIS.

  • It is clearly understood that e-navigation is beneficial to prevent collision and grounding of ships. The purpose of this study is to define and present a future ship operation system under the e-navigation environment in order to provide clear direction for the design of Korean e-navigation system. The future ship operation system consists of shipboard navigational system, shore supporting system and maritime communication system. To achieve the objectives of this study, the ship operation system was discussed separately into SOLAS ships and non-SOLAS ships in this study. In SOLAS ships, mariners become a system manager, choosing system presets, interpreting system output, and monitoring vessel response. In small ships and fishing vessels, mariners may enjoy their navigation by using the automatic tracking of ship's position on the portable electronic chart display. The improved bridge design, integrated and harmonized navigational system and single window reporting will reduce significantly the administrative and physical workload of mariners. Mariners can concentrate their attention more on navigational duty under the e-navigation environment. To build an effective Korean e-navigation system, the essential navigational functions and e-navigation services for small ships and fishing vessels must be identified and developed taking into account user needs.

  • The goals of the Global Maritime Distress and Safety System (GMDSS) that initiated by the IMO and supported by IALA, IHO, ITU, IEC and manufacturers are to provide more effective and efficient emergency and safety communications and disseminate Maritime Safety Information (MSI) to all ships on the world's oceans regardless of location or atmospheric conditions. Much of the GMDSS is built on technologies more than 20 years old; some work well; others do not. While GMDSS requirements apply only to SOLAS vessels, there are many other vessels on the water. So some considerations are necessary for non-SOLAS vessels including fishing ships, leisure boats and small boats. This paper describes the analysis of IMO, ITU and IEC meeting results held on recently. Also it gives the trends of the international marine radio standards and its technologies.

  • The INMARSAT is able to long range maritime communications that can not use for expensive charge in non-SOLAS ship. Therefore, international discussion for the question that replacements use of MF/HF band for maritime distress and safety communications in maritime. HF data communications system may be effectively utilized for SOLAS ships as well as for the existing non-SOLAS vessels including the fishing boats, which navigate A2 and A3 sea areas. The HF data communications may have various functions such as e-mail services, broadcasting services of up-to-date information related to marine safety, position reporting services, polling services etc. However, the present HF e-mail communications protocols have a problem of increasing calling redundancy as the number of channels in operation increases. This paper new protocol and communication sequence proposed in this submission establishes a proper radio link automatically and adaptively by taking channel traffic into account.

  • Based on the trend, there have been numerous researches analysing the ship collision risk. However, in this scope, the navigational conditions and external environment are ignored or incompletely considered in training or/and real situation. It has been identified as a significant limitation in the navigational collision risk assessment. Therefore, a novel algorithm of the ship navigational collision risk solving system has been proposed based on basic collision risk and vulnerabilities of marine accidents. The vulnerability can increase the possibility of marine collision accidents. The factors of vulnerabilities including bad weather, tidal currents, accidents prone area, traffic congestion, operator fatigue and fishing boat operating area are involved in the fuzzy reasoning engines to evaluate the navigational conditions and environment. Fuzzy logic is employed to reason basic collision risk using Distance to Closest Point of Approach (DCPA) and Time of Closest Point of Approach (TCPA) and the degree of vulnerability in the specific coastal waterways. Analytical Hierarchy Process (AHP) method is used to obtain the integration of vulnerabilities. In this paper, vulnerability factors have been proposed to improve the collision risk assessment especially for non-SOLAS ships such as coastal operating ships and fishing vessels in practice. Simulation is implemented to validate the practicability of the designed navigational collision risk solving system.

  • Electronic Navigational Charts(ENCs) are a database for the use of supporting the safety of navigation in marie voyage embedded within the navigational information in the Electronic Chart Display & Information System(ECDIS). Recently IMO made a decision on the mandatory equipment resolution of ECDIS for the international SOLAS vessels until 2018. With this regulation intention together the spontaneous uses from the wide range of marine applications are accelerating the increasing demand for ENCs at both of the navigational purpose and the non-navigational purpose. But there seems to be not enough guidelines or systematic approach for the service of the non navigational purpose. This paper deals with ENCs distribution issues. We present a integrated solution for the ENCs service of both user domains and also demonstrate the implemented results.
