Pre-implementation Tasks

The Largest Scale of the Coast Station Development Projects that have ever been implemented

The Republic of Indonesia (hereinafter “Indonesia”) is an archipelagic country which consists of more than 13,000 islands and its main means of traffic has been sea transportation since the old days. The Strait of Malacca and the Strait of Singapore that represent the surrounding sea areas have grown as the trunk arteries of international shipping which more than 90,000 ships per year are coming and going through. About 14,000 ships of Japanese flag are sailing though those straits, which are the important routes to support the Japanese trade.
However, marine accidents are increasing as the number of ships sailing in these straits is increasing. The demand for ship-to-shore communications has also been increasing. For safety of marine navigation, the radio communication system to cover all the waters of Indonesia is indispensable.

In 1983, JICA formulated the Master Plan of the Indonesian Coast Radio Stations and started the project of introducing the coast radio stations (shore base stations for ship-to-shore communications) in the entire country of Indonesia in order to allow a ship sailing in any water area in Indonesia to communicate with the shore side.

Japan Radio Company (JRC) participated in the five large-scale coast radio station projects for the period of 23 years including the first project in 1986, the second and the third and other additional projects, and supplied the coast radio station systems to Indonesia. Since then, the JRC systems have been operated in Indonesia. However, some of the system components have been superannuated. Further, the adoption of the GMDSS has been advocated by IMO. For these reasons, the forth project of the largest scale ever was started to develop 47 coast radio stations in the entire country of Indonesia and JRC participated in this project again.

≪Problems to Solve for the Project≫
It is mandatory to develop the ship-to-shore radio communication system to cover all the waters of Indonesia as the measure for safety of ships sailing in the Indonesian sea areas that have grown to be the trunk arteries of international shipping.
Increase in sea accidents as the marine traffic is growing.
Increase in the demand for communications between ships and shore.
Installation of the communications network to cover all the waters of Indonesia

JRC has delivered not only the coast radio stations to Indonesia, but also the Vessel Traffic System (sea/port surveillance system) to the Strait of Malacca in which the traffic of ships is particularly high in the waters of Indonesia. The JRC systems contribute to the comprehensive safety and security of all the ships navigating in the waters of Indonesia.

≪Summary of the 4th Project≫
Delivery and installation of the GMDSS-based communications equipment
Expansion and rehabilitation of the systems that had been delivered in the past, renewal of all the small-scale local coast stations, and introduction of the Automatic Identification System (AIS).

Introduction of GMDSS as recommended by IMO in 1992

Implementation Issues and Resolution Procedures

Introduction of the “GMDSS” as the international standard for safety of marine navigation

What is the GMDSS (Global Maritime Distress Safety System)?

The GMDSS is the international standard system to provide the distress, emergency and safety communications for the purpose of securing the safety of life at sea. It was recommended by IMO in 1992 as the new communications system to replace the conventional Morse code radio communications system. By introduction of the GMDSS, the international standard for the safety of marine navigation was established and the installation of the GMDSS was promoted in many countries. If any ship accident occurs, it is only necessary for the operator to push the “Distress” button to emit the distress signals of all specified frequencies.

Effects of Introduction of the GMDSS

The coast radio stations and the ships are watching the DSC (Digital Selective Calling) at all times to receive the distress signals from a ship in distress in the surrounding sea area and make prompt response to the accident. The introduction of the GMDSS allows the communications coverage to be drastically expanded so that the coastal radio stations in their neighboring areas can receive the distress signals promptly from the ship in distress in any water area of Indonesia. Therefore, the GMDSS can make great contribution to the search and rescue activity in Indonesia.

Post-implementation Effects

Interview with Ir. Bambang, Director for navigation, Directorate General of Sea Transportation (DGST)

Looking back at the coastal radio station projects for 30 years, Ir. Bambang , Director of Navigation said: “The systems and equipment installed in the 1st to 4th projects, which were implemented together with Japan Radio Company (JRC), are highly reliable and have won a very high evaluation.” In the large-scale projects that were developed in the entire country of Indonesia, each station has been rehabilitated in turn until the operations of all the coast stations have been established over the many years to contribute to the comprehensive safety and security of vessels navigating in the waters of Indonesia. About the change after the development of the coast radio stations, Bambang Director General talked about the improved quality of communications in the search and rescue activity: “The GMDSS delivered by JRC had been operated for the vessel management already before the 4th Project. The stations in Jakarta, Surabaya and other sites had been provided with the GMDSS equipment to secure the ship-to-shore communications necessary for the search and rescue activity in any water of Indonesia.”
For the future, he added: “In the 4th project, the expansion and rehabilitation of each station was implemented, and we think it necessary to continuously upgrade the stations in future.” His enthusiasm for the further system buildup is impressed.
