A Study on Improving Discrimination of Towing line of Tug-barge for Night sailing
Kim, Se-Won ; Jeong, Woo-Lee ;
Journal of Navigation and Port Research, volume 34, issue 5, 2010, Pages 305~309
DOI : 10.5394/KINPR.2010.34.5.305
This paper is provided to improve the discrimination of the towing line for tug-barge at the night sailing. As tugboat industry develops, marine accidents by tugboats are increasing. The main cause of accidents by tugboats is operators' negligence, and that portion is over 70 percent in total marine casualties by tugboats. The biggest cause of negligence is the passing through the towing line at night time. This paper suggests the ways to hinder operators' transit and improve discrimination of towing line(s) at night time.

Mobile Harbor(MH) is a new paradigm for maritime transport system introduced in Korea, the target of which is to carry out ship-to-ship cargo operation rapidly and effectively even under a condition of sea state 3. A MH ship is moored alongside a large container vessel anchored at the defined anchorage and also equipped with gantry cranes for handling containers. The MH study concerned includes rapid container handling system, optimum design for floating structure, hybrid berthing & cargo operation system, design for cargo handling crane, etc. This paper is to deal with a conceptual design of a stabilized mooring system and mooring equipment under a condition of ship-to-ship mooring. In this connection, we suggest a positioning control winch system in order to control heave motions of the MH ship which is to add constant brakepower and stabilized function to an auto-tension winch and mooring equipment used currently in large container ships.

For the purpose of technological analysis in the marine accidents and their prevention, IMO have made it obligatory to load VDR which is similar to the black box in aircraft. However, in case of body sinkage, capsizing, stranding and plunging which are almost 10% of marine accidents, it is difficult to take out the necessary data from the VDR in order to analyze the cause of them. Therefore, this paper apply the navigation dangerousness evaluation technology to the VDR to improve its performance. And we suggest that the vertical acceleration which is one of the factors for evaluating seakeeping performance of a ship is to be added in the existing VDR record data recommended by IMO.

The free surface influenced the wake behind a circular cylinder and its effects were investigated experimentally in a circulating water channel with the variation of water depth. Instantaneous velocity fields were measured in this paper. The measured results has been compared with each other to investigate the flow characteristics of the circular cylinder's 2-dimensional section at
using 2-frame grey level cross correlation PIV method. The flow around the circular cylinder with free surface affected the wake structure. Especially, in case of d=1.0D, the boundary layer was measured in the whole area. The separation point and boundary layer of the circular cylinder could be controlled by the water depth.

As the marine transportation has increased, the safe maneuvering system has been required. SOLAS obligated regulations for carrying AIS(Automatic Identification System) onboard. This system provides navigational information including identification, classification, position, a ship's course and voyage status from own vessel to ground and other vessels. Being utilized in the most development of application service for safe maneuvering, they are to be managed systematic. In this paper, we introduce a database system to manage the voyage status and navigational information of AIS message. It is classified by static or dynamic. An electronic navigational chart display system is implemented to verify the design.

Cheonan, Republic of Korea Navy patrol ship sank had happened by an unknown incident in the vicinity of Baekryeongdo southwest 1.6km(1 mile) sea at 21:45 on March 26, 2010. In terms of coastal researcher's point of view, it is meaningful to provide the sea condition of basic data necessary for search and rescue, more detailed predictions and inference data through the numerical simulations. Thus, in this study, we investigated the weather, wave, tide, tidal current, bottom soil conditions, and suspended sediment are investigated at the coast of Baekryeong-Daechung islands. And based on these data, the characteristics of sea conditions were analyzed. The tidal period at the time of incident corresponds between neap tide to mean tide. Until April 3-4 after March 26, the date of incident, the strongest velocity was progressed towards the spring tide. Thus, it was considered to be difficult to search and rescue operations. Also, because the ebb tide was in progress during 21:00 to 22:00, mass transport seems to be prevailed to the southeast. In particular, as the sudden turbulence due to the irregular topography existed was anticipated, we had carried out particle tracking experiment. From this experiment, depending on the situation of flow, the initial movement of the particles were directed to the southeast but it turned out moving towards the offshore based on the long term prediction. Through this result, it is considered that the scope of the search operation should be expanded towards the open sea.

As a port city, Qingdao had been developed through the 4 stages during the first half of the 20th century. First stage is German Occupation period. In this period, the old downtown of Qingdao was formed and the existing architectural characteristics of Qingdao had been established. Second stage is the First Japanese Occupation period. Japanese transformed Qingdao into Japanese city and expanded city area to north and east. Third stage is Northern Warlords and the National Government period. In this period, Qingdao had been developed as an international city of world trade and vacation. Forth stage is the Second Japanese Occupation period. Japanese tried to change Qingdao as a military base for the invasion of the northern China.

When the numerical analysis is carried out, it is necessary to set proper elements as a feature of analysis domains for more accurate simulations. In this study, Distinct Element Method(DEM) is applied, only considering repulsive force and tensile force except for frictional force and resisting force of particle. When the filled particles with initial Quad-tree type is relocated by DEM, a blank space existing among the particles can be minimized because the shape of particle is circular. Finally, it is the effective feature that the centroidal disposion of the particles is similar to an equilateral triangle. Triangular mesh are formed by using the Delaunay triangular technique on these relocated particles, the quality of triangular mesh is more improved by carrying out Laplace interpolations. The compared result of Aspect Ratio before and after the Laplace interpolation is shown that although the quality of triangular mesh made by DEM is good, the later triangular mesh are higher quality than the formers. In this study, although the developed technique takes a longer calculational time than the previous technique to generate triangular mesh, it is considered that the applicable possibility is very high in the generation of finite element mesh about wave analysis and various numerical simulation to need a complex or reappearance of exact topography.

Recently, it becomes important for container ports to gain competitiveness through service differentiation strategies. These strategies require an objective evaluation on consumer needs. For that reason, this study aims at developing the scale and measurement methods for service quality. Container shipping companies calling at Busan are targeted for the empirical analyses. The measurement items are presented for the services that they are provided from entry into a port to departure from a port. Exploratory factor analysis and validity analysis are done to derive a service quality scale from entry to departure. The result of regression analysis implies that the service quality scale is useful to increase customer satisfaction and to establish managerial strategies.

The Currently, most cargos of container transshipment between Busan Port and New Port are transported over land, and the rest is transported by barge. This study estimated firstly the traffic between those ports through simulations in order to analyze the feasibility of container transshipment by barge. It forecasted annual profitability using determinants to affect on the barge business by the traffic, and then, discussed the feasibility. This study supposed the flexible scenarios with 50%, 60%, 80%, or 100% transshipment and the 25 monthly barge service numbers between two ports, and measured the influences of different factors according to the above various scenarios. And then the sales were evaluated by the different traffics and freights scenarios provided the business would be actually operated. Finally, Net incomes were simulated to analyze the feasibility of different scenarios by various traffics and freights. The net income should be positive to get the feasibility. To achieve this, the minimum traffic should be secured and the lowest freight per TEU should be determined. While all countries of the world is controlling CO2 emissions and emphasizes the green logistics, this study contributed to solve at the same time the problems about the pollution and the efficiency of transportation by reviewing positively the feasibility of barge transportation as an alternative to transportation overland.
