Abstract

Abstract The paper analyses the performance of an Automatic Vessel Identification System on Medium Frequency (AVISOMEF), which works with the Grid Method (GM) on high density maritime European routes using real data and uniformly distributed data. Compared to other systems, AVISOMEF is a novelty, as it is not a satellite system, nor is it limited by a given coverage distance, in contrast to the Automatic Identification System (AIS), though in exceptional circumstances it leans towards it. To perform the analysis, special simulation software was developed. Moreover, a number of maritime routes along with their traffic density data were selected for the study. For each route, two simulations were performed, the first of which based on the uniform traffic distribution along the route, while the second one made use of real AIS data positioning of vessels sailing on the selected routes. The obtained results for both simulations made the basis for formulating conclusions regarding the capacity of selected routes to support AVISOMEF.

Highlights

The work described in the paper was preceded by several earlier research stages: Firstly, in our past publications [1], [2], [3], [4], [5] we described the proposal of a new Automatic Identification System for Medium Wave Vessels (AVISOMEF)
They are named as A and B, following the path previously explained for the Traffic Control Centre (TCC)
The first TCC is located further north, and from there, following the set direction, the second is in the English Channel, third in Brest, fourth in Finisterre, fifth in Lisbon, sixth in Cadiz, seventh in Sardinia, eighth in Sicily, and the final ninth TCC is in the south of Greece

Summary

Introduction

The work described in the paper was preceded by several earlier research stages: Firstly, in our past publications [1], [2], [3], [4], [5] we described the proposal of a new Automatic Identification System for Medium Wave Vessels (AVISOMEF). A brief synthesis of this system is given in this paper. The objective of this work is was to perform a stress test of AVISOMEF and obtain reliable results concerning its operability. To complete this objective, first we implemented the system to study an extensive, international route with adequate traffic density. First we implemented the system to study an extensive, international route with adequate traffic density It was, as shown, the route that surrounds Europe
