The current status and future issues in human evacuation from ships

The International Maritime Organization (IMO) developed guidelines in May 1999 for the evacuation analysis of Ro-Ro passenger ships to prevent loss of life in maritime accidents. However, IMO considered these guidelines only as an interim measure and allocated 3 years for their improvement and further development as very limited experience and data were available. In this paper, the requirements of the IMO and current research regarding ship evacuation are reviewed. In addition, applicable evacuation models are presented as well as several experimental methods of obtaining the data of human behavior in regard to listing and the dynamic effect of waves on a ship are evaluated. Recommendations on further issues are discussed at the end.

Employment of wireless sensor networks for full-scale ship application

In this study, basic experiments regarding the wireless sensor network were conducted on a 3,000-ton-class training ship as the first step in applying the ubiquitous technology to a real ship. Various application fields of the technology in terms of the provision of safety and convenience on a ship would be extracted through these experiments. To efficiently adopt the ubiquitous technology for ship application, it is necessary to identify the state-of-the-art ubiquitous technology and to prepare countermeasures against the harsh environment of a ship. Especially, the characteristics of the wireless sensor network were investigated at the test bed ashore as well as on a real ship to figure out the complementary items before full-scale ship application.

Experimental Tests on the Wireless Sensor Network and the Power-line Communication in a Real Ship and Laboratory

Abstract Basic performances of wireless sensor network (WSN) and power line communication (PLC) confirmed in the test bed ashore are investigated in the 3000-ton class training ship of Korea Maritime University. The ubiquitous technologies can be considered for the provision of safety and convenience in a ship. We employed WSN and PLC, as the ubiquitous technologies, at the two areas within the training s hip to estimate the realization of the ubiquitous environments in a ship. The experiments show rather good results in terms of data transfer rate. However, more detailed studies concerning the connection between WSN and PLC, noises induced to power line and fading ef fects are required to improve the quality and the stability of the communication for the ubiquitous environments. ※Keywords: Ship(선박), Wireless senor network(무선센서통신망), Zigbee(지그비), Power line communication(전력선 통신), Ubiquitous(유비쿼터스) 1. 서 론 언제 어디서나 필요한 정보를 얻어 필요한 서비 접수일: 2007년 12월 3일, 승인일: 2008년 5월 6일 †교신저자: ppaik@moeri.re.kr, 019-358-0255

A Study on USN Technologies for Ships

This paper describes the ubiquitous computing technologies for ship, which is produced and assembled by many steel blocks. It particularly describes the testing of a 2.4 GHz wireless communications platform, especially zigbee, on a number of intelligent devices, with the blocks disturbing the wireless communication. The power line communication that is established in a ship already is also experimented for some data transfer. At last, the RFID technology is applied at the test bed that is composed of three steel containers. In this paper, we implemented some USN technologies in the test bed simulating a ship environment and investigated the basic characteristics of ubiquitous computing technologies. Possible applications of such ubiquitous computing technologies to ships are also introduced here in.

Application of ubiquitous technology to ship environment

Many new technologies from different area are employed in enhancing the safety of ships. This paper proposes using recent ubiquitous technology in order to enhance ship safety. Ubiquitous technology can also provide valuable addition to the ships service as well as high quality of life to crews and passengers. In this paper, Zigbee communication performance in ship environment is tested in resembling environment and under ship operation condition. Based on the performance of Zigbee communication, a sensor network configuration using Zigbee and PLC (Power Line Communication) is proposed and tested during ship operation. Two application of ubiquitous technology to ship is introduced as well.

A Study on the Damage Safety Assessment in Ship Design Stage

AbstractRecently ship safety regulations are being reinforced to improve maritime safety and to prevent maritime pollution by International Maritime Organizati on. It means that the regulation is becoming more proactive rather than reactive. In the mean time, design philosophy is also moving from rule based design to performance and simulatio n based design. In this paper, a study on practical application of the damage safety assessment system is carried out. The damage stability and the survivability of a cargo ship that was designed based on current regulation is investigated using performance based design tools in order to improve the safety of the design and verify the performance of the developed damage safety assessment system. To do this, damage scenarios is established and the characteristics and geometry the cargo ship is modeled. A new design alternativ e is proposed with small change in the internal arrangement based on safety evaluation r esults of the current design. ※Keywords: Damage(손상), Survivability(생존성), Safety assessment(안전성평가), Ship design(선박설계)

RFID Based Management System for Spare Parts in a Real Ship

Abstract In this paper, RFID (Radio Frequency Identification) based management system is introduced to control effectively logistic supply items and mac hinery spare parts in a ship. To apply an RFID system under very harsh environment in a ship which is a steel-structured small area with lots of compartment, we measured reading distances and angles in open space, in an steel compartment, and an real ship separately in order to investigate the reliability between various tags and RFID. ※Keywords: Ubiquitous sensor network(유비쿼터스 센서 통신망), Ship(선박), RFID(무선주파수 인식기술), Tag(태그), Reader(리더), Spare part(예비 부품) 1. 서론 현재 선박에서는 각 장비 및 예비품을 관리하기 위해 선원들이 주기적으로 점검하고 그 결과를 수기로 적은 후에 컴퓨터에 정보를 입력하여 육상의 통합망에서 관리하고 있다. 그러나 이러한 작업은 많은 시간과 노력이 필요하고, 부족한 물품을 준비하는데 응답시간이 상대적으로 늦기 때문에 선박의 운항에 차질을 주거나 심각한 경우 큰 위험 접수일: 2008년 6월 25일, 승인일: 2009년 2월 2일 † 교신저자: scho@moeri.re.kr, 042-868-7670 을 초래할 수 있다. 또한 선박의 갑판이나 기관실 등에서 사용되는 장비들은 예비 부품을 적절한 시기에 교체해 주어야 한다. 이를 위해 Kim et al.(2004)은 선박에서도 편리하고 안전한 항해를 위해 승무원, 승객, 물품과 화물을 위한 각종 정보들을 관리할 필요성을 제기하였고, Lee et al.(2005)은 파랑 정보, 선박의 침로, 선속, 굽힘 모멘트, 선수 가속도 값 감시 등을 통하여 내항성 감시에 대한 방법을 제시하여 궁극적으로 운항 선박의 운동 안전성 및 효율성을 높이고자 하였다. 또한 Cho et al.(2007)은 선박의 운항이 아닌 승무원의 편의성과 작업의 효율성을 위
