휴대형 도선 지원 시스템 개발에 관한 연구

Abstract

The size of the ships involved in international trade has increased dramatically over the years, but many ports have been unable to match the increase, largely because of the huge costs involved in overcoming topographical constraints. The result is that the operating clearances have become progressively more restrictive. However, even where major capital works are cost-prohibitive, new technology can help by providing a plan view of the vessel's position at all times, allowing the pilot to manoeuvre more precisely than would otherwise be possible.

Although ships have become more automated, pilots must still rely on their own resources for critical information during pilotage. The pilot brings local knowledge and ship-handling expertise, but often has to cope with not only be unfamiliar but is also potentially unreliable. Under pressure, the system can break down sometimes with catastrophic results.

In most situations, support for the confirming the position and predicted movement of the ship is done primarily by eyes. Ships which are ECDIS-fitted can provide a real-time position display but the quality of the chart is often uncertain and its scale not always appropriate for harbour work, and few ports have proper ENC charts available.

For these reasons, we proposed the PDSS(Portable Docking Support System) that seeks to develop a technology demonstrator portable pilot equipment for the first time in Korea that can receive data from a shorebased system, such as track and environmental data, and thus, together with its stored data, and, at sea, other vessel's AIS, display a comprehensive traffic image. The equipment will meet the user's needs, be stand alone and function autonomously. With a variety of communications interfaces, the equipment will also be capable of transmitting back to a VTS centre data required for traffic and port management. The effect will be to improve both navigational safety, reduce voice radio communications and provide a beneficial impact on the efficiency of traffic flow.
