좁은 수로에 관한 국제해상충돌방지규칙상의 서술은 모든 구체적 상황을 포괄하여 명시하지 않으므로, 실제 항법 적용상 다툼이 발생할 수 있다. 예컨대, 좁은 수로를 항행하고 있는 선박과 수로에 진입하려는 선박이 서로 횡단하는 상황에서 좁은 수로의 항법이 적용될 것인지에 대한 의문이 발생한다. 2015년 발생했던 The “Alexandria 1” and “Ever Smart” Case에 대한 영국법원의 판결은, 이 문제의 보편적인 해결 방안, 즉 좁은 수로상에 있는 선박에게는 좁은 수로의 항법만이 적용되어야 마땅하다는 결론을 제시하였다는 점에서 큰 의의가 있다. 다른 한편, 2017년 발생했던 “한림페리9호·민호호 충돌사건”에 대한 대전 고등법원의 판단은 외관상 영국법원과 크게 다르지 않지만 논증구조는 판이하며, 향후의 지침이 되는 판결을 내리지 못한 것으로 보인다. 본 논문에서는 상기 판결들에서 좁은 수로 인근에서 발생한 선박 간 횡단 상태에 있어 좁은 수로의 항법 적용을 정당화하는 과정이 어떻게 달랐는지 법적 논증이론의 관점에서 검토한다. 한국법원과 영국법원은 유사한 결론에 도달하 였지만, 한국법원은 논증상 합리적인 근거를 제시하지 못하였다는 점에서 정당화 맥락의 부족함이 지적된다. 이러한 논의의 목적은 특수한 상황에서 어떤 항법 적용이 옳은지를 밝히는 것이 아니라, 판결의 바람직한 근거 제시 방향에 대해 제언함에 있다.

「국제해상충돌방지규칙」과 이의 국내입법인「해사안전법」은 좁은 수로에서의 항법과 관련하여 넓은 바다에서 적용되는 일반항법과는 다른 지리적 특수성을 이유로 특별항법을 규정하고 있다. 이러한 특별항법은 일반항법의 경우에 인정되는 피항의무, 유지의무와는 다른 통항금지의무를 규정하고 있다. 한편, 좁은 수로에 대한 횡단의 경우에는 소형선박, 어선 등에게 부여된 ‘다른 선박의 통항을 방해하여서는 아니 된다’는 통항방해금지의무와 다르게 ‘다른 선박의 통항을 방해하는 경우에는 횡단하여서는 아니 된다’고 규정하고 있는바, 제정목적과 법문에 충실한 해석에 의하면 이를 통항방해금지의무와 다른 횡단 금지의무로 보아야 하는 것이 상당할 것이다. 따라서 그와 같이 해석하여야 하는 이유 내지 근거, 달리 본다면 어떤 의무와 책임을 부담시켜야 하는지를 살펴보고, 이에 상응하여 상대선박은 어떤 의무와 책임을 부담하는지에 대하여 검토하고, 마지막으로 합리적인 좁은 수로 항법에 대한 조문이 되기 위하여 향후 추가 연구를 통해 보완하여야 할 부분이 있음을 제시하였다.

Recently, as the coastal trading is being increased rapidly, risk of collision being increased especially in the coastal route near around the port of Wando. In this paper, with the reference to various literatures and papers on collision avoidance rules, the navigational rules and regulations for the coastal area-especially for the narrow channel-are construed and introduced in brief. Also, 3 collision cases near around the port of Wando and statistical data during 5 years(1996 to 2000) are studied. The results of this study are as follows; 1. It is strongly recommended to separate the route of east-bound and west-bound in this area due to removing the risk of collision between the vessels in reciprocal way. 2. The owner of the fleet should lead that the master should con the vessel by himself when passing this area. 3. For the introduction of the Coastal VTS, it is required to investigate the capability to cooperate with military radar sites which based on all over the coast.

The assesment of the safety of ship's transit in a curved narrow channl consists of the maneuvering safety determined by the chance of running aground, the maneuvering difficulty determined by shop's workload, and shiphandler's subjective evaluation. In this study to examine the correlation between shiphandler's subjectice evaluation and the maneuvering risk, the real-time and full-mission shiphandling simulator in the Korean Marine Training & Research Institutes(KMTRI) was utilized. In the conning bridge of the shiphandling simulator, 50 experienced masters conducted masters conducted the modeled vessel of 60,000 deadweight tonnage along the designed channel under 3 different envrinmental conditions. The findings were as follows: (1) The frequencies of stress levels, work difficulties, vessel controllability and overall workload of shiphandlers are similar irrespective of environmental conditions and they are able to be represented as shiphandler's subjective evaluation. (2) It is possible to assess and analyze theoretically the correlation between the shiphandler's subjective ecaluation and maneuvering risk each environmental cindition by quantifying the data obtioned from the tests. The results are as follows: ① As the degree of maneuvering risk increases, the shiphandler's subjective evaluation increases sharply near the curvature area of the desgined channel. ② In the area of the curvature of the designed channel, maneuvering risk increases sharply with the danger of running aground under the environmental condition of current and wind comung from the stem.

대법원은 2004추65(2005년 9월 28일 선고)에서 "좁은 수로 항법은 좁은 수로에서의 선박의 충돌을 효과적으로 예방하기 위하여 선박의 종류나 기상 상황 등에 관계없이 적용되는 특별항법으로서 조종제한선이라고 하여 적용이 배제되지 아니하므로, 좁은 수로에서는 상대 선박으로부터 진로 우선권을 양보 받았다는 등 다른 특별한 사정이 없는 한, 조종제한선이라고 하여 좁은 수로 항법을 지키는 선박에 대한 진로 우선권이 보장되는 것은 아니다"고 판결 하고 있다. 이것은 선박 사이의 책무 규정과 좁은 수로 항법 해석에 혼란을 야기할 여지가 있다. 따라서 이 논문은 좁은 수로 항법과 선박 사이의 책무 규정에 관하여 올바른 해석론적 방향을 제시하고자 대법원 판례를 중심으로 좁은 수로에서의 조종제한선의 항법상 지위에 관하여 논하고자 한다.

하천은 지역마다 독특한 하도특성을 지니고 있다. 우리나라는 전 국토의 70 %가 산지로 구성되어 있으며, 이 가운데 노년기에 지형도 적지 않다. 이를 가로 지르는 우리나라 하천에서 특이한 하도형태의 모습을 보이는 구간이 곳곳에 산재하고 있다. 그 대표적인 모습이 충적하도와 침식하도가 연속해 발생하는 과정에서 나타나는 하천 협소부이다. 하천 협소부란 하천지형학에서 일반적으로 쓰이고 있는 용어이며, 하도수리학에서는 지배유량에 종속되는 일정하폭의 범위를 크게

Nowadays LNG has been beginning to take the place of petroleum as fuel all over the world and VLCC of LNG will take the same sea routes that had been used by VLCC tankers of petroleum in the last part of the 20th century. The transportation of LNG by a VLCC include more dangerous nature of sea peril than that of petroleum. We already know the dimensions of a disaster a LNG tanker could bring about in the case of the LNG tanker, Yuyo-Maru No. 10 in the Tokyo Bay of Japan in 1974. From the point of safety when we construct a LNG base or LNG pier in the base, the appropriate government authority and constructing company had better take sea pilots or some ships handling experts to participate in a prior consultation of the design of the project. A G/T 100,000 ton LNG base and pier were completed in November of 1996 in Inchon harbour in Korea and VLCC of LNG of G/T 100,000 ton class have been entering into the base ever since. This study was started and completed In comply with the requisition of the Sea Pilot Association of Inchon harbour in advance of the opening of the LNG base. As the entrance and exit channels leading to Inchon harbour were constructed in the years of 1930s, it was one of the most pressing works for Inchon sea pilots in 1996 to certify the method of safe passing maneuvering of a G/T 100,000 ton of LNG tanker through the Pudo narrow channel prior to commencing actual piloting of the VLCC of LNG. The authors made some mathematical models computing maneuvering of a vessel changing her course with her control surface through a narrow channel and computed maneuvering of a G/T 100,000 ton of LNG tanker and also made maneuvering simulations of the vessel by a desk-top simulator. The results of computations and simulations are well coincided with each other in qualitative aspects to assure safe passing of the VLCC of LNG.

When designing new marine traffic routes, it is desirable that the congestion due to traffic volume is evaluated by theoretical traffic capacity or by traffic simulation. Most of these techniques are applied to single server which is not considered channel width. Over-taking or paralle sailing of two or more vessels is allowalbe in Dover, Uraga, Gaduk-sudo, etc under their traffic capacity. In this paper, the Bumper Model is introduced to multiple severs in narrow channel and applied to Uraga Channel in Japan. The minimum width of Uraga Channel is 1, 400 m and its design traffic capacity is evaluated 19.26 ~ 19.52% of the basic traffic capacity. The traffic capacity on Gaduk Channel according to Busan New Port Development in 2011 will be estimated 3.59 % of maximum density and equal to 18.6% of that on Uraga Channel in 1992. The channel width Gaduk-sudo is designed 1, 600~2, 460 m and evaluated safe enough.

It was possible to assess and analyze theoretically the correlation between the shiphandler's subjective evaluation and maneuvering difficulty under each environmental condition by quantifying the data obtained from the tests. The results are as follows: ① As the degree of maneuvering difficulty increases, the shiphandler's subjective evaluation increases in the designed channel under the designed environmental condition. ② In the straight area, not the bend of the designed channel, maneuvering difficulty increases sharply under the environmental condition of current and wind coming from the stern.
