This article aims at suggesting a practicla auide to navigation under restricted visibility by a study of an English court. This case os a good example of setting out safe speed. close-quarters situation, safe passing distance as the above factors are not enumerated in Collision Regulations.

This research does by purpose that present safe navigation plan for ships during doing dredging construction with dredger crossing waterway of Gadeok. Dredging operations need to build sunken tunnel that cross the bottom of the sea under waterway of Gadeok for access road construction between Busan- Geoje. Accordingly, dredger must cross and dredge waterway of Gadeok fatally. There is possibility of marine accident of collision for latent danger situation of ships to navigate waterway of Gadeok relatively. Therefore, safe navigation plan of ship is groped in reply and its countermeasure is presented.

There is possibility of marine accident of collision for latent danger situation of ships to navigate waterway of Gadeok relatively. Therefore, safe navigation plan of ship is groped in reply and its countermeasure is presented. Firstly, navigating traffic in daytime was forecasted less than 20% of its maximum capacity through estimating the traffic volume and traffic congestion The proposal was presented to execute dredging operations in three-step and to establish temporary waterway after reviewing waterway design principles. The role of VTS center was emphasized in the new Busan Port, lastly.

Port industry has achieved a remarkable growth with a help from increase in container shipment and above all, transshipment that reflects international competitive power of Port industry amounts to 36% of the national harbor shipment. Therefore, this study speculates the impact of Port industry on national economy using the inter-industry relation table. As it considers the reason why international competitive power in Port facilities decreased as absence of investment, it is to present an effective investment plan for Port industry. Though Port industry as one of main national key industries play an important role in production of national economy, it has been evaluated as having relatively less importance. And when Port industry is managed independently, relying on foreign countries without improvement, price increase due to improper agreement of foreign enterprises and problems relating to securing safe transportational vehicles will have tremendous impact on national economy. And they should try to create added-value and support re-export of the exported and imported shipment through their processing and packaging by making Port zones bonded area. production of national economy, it has been evaluated as having relatively less importance.

AGV is very proper equipment for Port Automation. AGV must have Obstacle Detection System(ODS) for port automation. Obstacle Detection System must have some functions. It must be able to classify some specified object from background data. And it must be able to track classified objects. Finally, ODS must determine its next action for safe cruise whether it must do emergency stop or it must speed down or it must change its track. For these functions, ODS can have many different structures. In this paper, we will propose one structure among some possible ones. Our ODS has been being developed using proposed structure since last year. In this paper, we will introduce our system which is under construction.

This paper is to investigate the minimum safe distance between T/S Hanbada and a group of vessels participating in the event hosted by M broadcasting station who asked T/S Hanbada to keep a distance from $100m{\sim}500m$. The minimum safe distance was assessed by using ES Model which evaluates quantitatively the difficulty of shiphandling, and the simulation of marine traffic flow. As a result the minimum safe distance of T/S Hanbada moving at a speed of 2 knots turns out about 260m and is compared with the actual value.

In the Sailing Rules of International Regulation for Preventing Collisions at Sea, 1972, any definite distance between two vessels approaching each other is not referred for adequate maneuvering to avoid collision. At sea the officer in charge of bridge duty is required to guess safe distance before he takes maneuvering actions needed to avoid collision. Papers on safe distances calculated on the base of the motiional characteristics of ships for collision avoiding actions are very few. In this paper, the minimum safe approaching distances necessary for actions to be taken to avoid collision are calculated in numerical numbers definitely by mathematic formula based on the maneuvering indices got from experiments of actual ships. On the assumption that two vessels same in size and conditions are approaching each other, the author calculated the minimum safe approaching distance as 4.5 times, sufficient safe approaching one as 9.0 times the length of the ship involved in head-on situation and 5.0 times, 10 times respectively the length of the ship in each case mentioned above in crossing situation.
