The development of international trade after World War II has led to a substantial increase in sea traffic, A wide variety of cargoes that are combustible, toxic or chemically reactive are carried by ships built according to certain Codes. Despite the international effort to ensure safety at sea, the standards for the design, construction, alteration,repair, maintenance and manning of many ships are not stringent and comprehensive. Furthermore, the inspection and enforcement of the international rules are usually left to the flag State. As a result of the non-adherenceto the international standards and the lack of an affective inspection, traffic in certain areas creates hazards to life, property and the marine environment. As these matters are of national concern, some shore-based stations began to control the movement of ships in certain areas. In the past these stations used to provide routeing Information to vessels on the high seas. Although their role was modest, their services proved to be valuable and masters frequently relied on their information.

The introduction of the traffic separation schemes gave the shore stations an opportunity to expand their role. They started to monitor the movement of the ships while passing through the scheme in order to detect any infringements. It also became necessary for them to give advice to avoid any accident. In fact, the role of these stations went far beyond an information service and developed to a kind of surveillance system. In recent years, certain incidents caused damage on a large scale and casualty statistics showed that most of the accidents occurred in narrow channels, waterways and within the areas of the ports. Even without waiting for a major incident, the possibility of an explosion or a gas carrier with massive destruction to port installations cannot be ruled out. On the other hand, some of the shore-based stations are provided with modern equipment which can give an early warning of a possible danger and assist in a smoother flow of traffic. By making use of these modern machines and controlling the movement of gas carriers and other vessels carrying dangerous goods, many accidents could be prevented.

However, the idea of traffic control is marked with an air of mystery and confusion and this paper attempts to clarify:
(I) the limits of the port and the various zones
(II) the control system
(III) the liability for controlling the movement of gas carriers.
