포항종합제철(浦項綜合製鐵)은 제품출하시(製品出荷時) 해송비(海送比)를 약(約) 80% 정도(程度)로 잡고 있으며, 현재(現在) 하루 평균(平均) 약(約) 3,000ton가량의 제품(製品)이 출하(出荷)되고 있다. 따라서 강재품(鋼材品) 수송(輸送)에 push-barge system을 적용(適用)했을 경우에 각(各) 주요예상소비지(主要豫想消費地)의 1일(日) 예상소비량(豫想消費量)을 장래의 시설확장(施設擴張)을 고려(考慮)하여 1,000ton/day에서 4,000ton/day까지 가정하였고 속도(速度)는 연안화물선(沿岸貨物船)의 예(例)를 따라 7knots에서 13knots까지에 걸쳐 조사(調査)하였다. 회항시(廻航時) 화물(貨物)은 일단 없는 것으로 가정하였으며 몇가지 생각될 수 있는 것은 schedule중(中)에서 "1 tugboats: 3 barges", "2 tugboats: 4 barges", "3 tugboats: 5 barges"의 3가지만을 대상(對象)으로 하였다. 조사(調査)한 결과(結果) 소비량(消費量) 1,000ton/day인 경우에 포항-울산(浦項-蔚山) : 1,000 DWT barge, 8 knots, 1 tugboat: 3 barges 포항-부산(浦項-釜山) : 1,550 DWT barge, 8 knots, 1 tugboat : 3 barges 포항-인천(浦項-仁川) : 2,690 DWT barge, 9 knots, 2 tugboats : 4 barges 등이 최적(最適)인 것으로 나타났다. 또 자항화물선(自航貨物船)과 비교(比較)하면 같은 크기의 자항화물선(自航貨物船) $2.5{\sim}3.0$척(隻)에 해당(該當)하는 효율(效率)을 가진다. 이 결과(結果)로 미루어 보건대 push-barge system은 앞으로 연구개발(硏究開發)의 충분(充分)한 가치(價値)가 있는 것으로 생각된다.

Construction of the Kyung-Inn Canal between Inchon and Han River water way of 18 kilometer length is considered recently. The canal may reduce traffic congestions between Seoul and Inchon, remarkably. Since the type of transportation system of the canal will be barge system, an analysis on the canal barge characteristics is carried out in this paper. The merits and demerits of various canal barge transportation systems are studied, respectively. Also, several barge connecting systems are studied and the corresponding characteristics are analyzed and compared. Optimal barge system is selected based on the simple modeling of the several barge systems and the relevant evaluations. Primitive design issue of the barge transportation system of the canal is also presented.

This paper is a part of the development on the safe navigation model of tugs and barges in Korea waters. desk-top tug-barge simulator is to train the crew of tugs and barges, especially tugs' crew. It is connected with steering and engine telegraph console and winch control console, and can describe three types of operation mode for a tug-barge working unit, towing mode, side by side and push mode. It can also record and assess each simulation run. The evaluation module can confirm the result of a finished simulation run and help trainees to find and correct their faults, and it is composed of result evaluation and process evaluation.

Because of the rapid growing traffic volumes of cargo, especially between Seoul and Inchon, and lack of investment into transport infrastructure in the past, in Kyong-in area have suffered from the serious traffic congestion in the public-road and the express-way network, But the further expansion of the traffic volume in near future is difficult due to burden of the higher expansion of the traffic volume in near future is difficult due to burden of the higher construction cost. Although the traffic congestion on the Kyung-in railway, is not very serious comparing with the road sector, the shortage of capacity on some main lines becomes emerged as a problem as railway traffic has increased. Unlike these two modes, the water transport, which has been paid relatively less attention for commodity transport in Kyong-in area, has not any constaint in this respect. Han river has been used as a water transport route in Chosun Dynasty which is called Cho-wun. This paper therefore aims to propose the availability of Han river as the alternative water transportation mode, in order to decrease the congestion between Seoul-Inchon by considering the construction of Kyong-in artificial water channel in near future. In this paper, we investigate the availability of Nanji-do as the physical distribution depot connecting with the circulation express way in the national capital distribution depot connecting with the circulation express way in the national capital. We also estimate the traffic volume by using the push-barge carrier (300DWT) in the same channel through the simulation under some assumptions such as ship's turnaround time, speed, etc.
