Docking system based on laser measurements: Port of Koper case study

Abstract

Smart systems are utilized in ports to provide safe handling of container carriers. A docking system, enabling very precise measurement of distance from vessel to quay aims to provide safe berthing. Such a system, supported by piloting functions (navigational chart and others) provides independent and reliable navigational information, reducing the amount of time spent on the procedure and eliminating uncertainties that could otherwise lead to accidents or incidents-at the very least delays. The increase in container throughput at Koper was made possible by extensive dredging activities and a pier extension. These activities have lengthened the container terminal so that it is now possible to berth a large mother vessel. To assure safe navigation through the narrow and bending channel, a laser-ranging system has been implemented. When a large container vessel is positioning alongside a quay where inadequate fenders are in place and Ship-to-shore (STS) cranes are close to the approaching ship, special care is required and parameters such as precise vessel position, transversal speed, and vessel-approaching angle are of great importance. To provide the information in real time, a laser docking system has been developed and integrated with metocean data. This paper will present the layout of the system and the first results related to the observed docking of large container vessels calling at the Port of Koper.
