Maritime Traffic on Approach to Port of Split and Assessment of Collision and Grounding Risk

Abstract

The Port of Split is the largest Croatian passenger port and its access fairways, characterized by a very high likelihood of accidents, especially of collisions and groundings, the busiest in the Croatian part of the Adriatic. This paper analyzes the main access fairways to the Split City Port, as well as those leading to the Kaštela Bay and the North Port of Split. Small vessel maritime traffic is also analyzed, although it is neither continuous, nor follows any established main routes. The AIS vessel movement data served as the basic source of data for larger vessels, and arrival/departure reports of port authorities for other maritime traffic. Main access fairways, maritime traffic concentration and structure, as well as assessment of collision and grounding risk are defined in keeping with the obtained data.

Influence Of Hydro-Meteorological Elements On The Ship Manoeuvring In The City Port Of Split

“…Manoeuvring in limiting conditions, or above them, is extremely precarious, especially bearing in mind the fact that these are all passenger or ro-ro passenger ships, i.e., ships with a large number of people and vehicles, and that manoeuvring itself is performed in the immediate vicinity of coastal pedestrian zones and generally in the vicinity of valuable infrastructure. Marine accident statistics show that one of the most frequent types of accidents are groundings due to the failure of one of the ship`s systems or to the loss of control as a result of adverse weather conditions, and they happen on average every two to three years (Lušić et al 2016). There have not been any accidents with major consequences in the recent history, which does not mean that the level of safe manoeuvring within the port is on a satisfactory level considering there are no formally defined limiting conditions.…”

Every Vessel Counts: Neural Network Based Maritime Traffic Counting System

“…However, relying solely on AIS and VTS to monitor vessels has limitations. Not all vessels are required to have AIS on board, resulting in incomplete data [ 1 ], and it can be difficult for VTS to accurately identify and track vessels in crowded or complex port environments. This problem is particularly relevant in Mediterranean passenger ports such as the Port of Split, where maritime traffic is diverse and consists of a large number of vessels that are not covered by traditional vessel monitoring systems [ 2 ].…”

“…As described in [ 2 ], due to the port structure, traffic ranges from smaller boats of all types, such as sailboats and speedboats to passenger ferries and large cruise ships. Traditional traffic monitoring systems have proven inadequate for monitoring and counting this variety of vessels, resulting in an incomplete or inaccurate traffic analysis [ 1 ]. The ability to accurately count vessels provide valuable data for scientific research, such as maritime traffic density analysis [ 22 ], collision probability modeling [ 23 ], or environmental monitoring [ 24 ].…”
