Overview & Objectives

Maritime Volumetric Navigation System - ARIADNA


The goal of the project ARIADNA is to design a new concept and build a new series of navigation support systems which facilitate:

Æoptimisation of the use of maritime and inland infrastructures,
Æsafe navigation in dense traffic situations in ports, rivers, channels, lock and port access areas,
Æimprovement of traffic separation schemes,
Æimproved risk control, including grounding,
Æefficient and environmentally-friendly operations.

ARIADNA based products can be also useful to avoid human error in navigation. The new system provides warning and manoeuvring support for collision avoidance, as well as risk and warning assessment to vessel and navigation control systems in different maritime scenarios such as channels, port access areas, narrow inland waterways and congested areas.

ARIADNA system aims at the implementation of the Volumetric Navigation System (VNS) for maritime and inland navigation according to the following preconditions:

ÆThe system combines data on navigation, position and vessel characteristics with time information about relative positions in regard to vessels and infrastructures  that are located in its surroundings.
ÆThrough the usage of VNS, all vessels share information in order to be part of a collaborative navigation network.



The overall objective of ARIADNA project is to optimise the use of maritime and river infrastructures in order to manage increased traffic density and, at the same time, improve safety at congested maritime and inland areas with the support of the last ICT navigation aids.

In the framework of the project, specific objectives are also defined:

ÆDemonstrate and support feasibility to reduce the traffic separation by at least 20% on high density traffic regulated areas as based on a realistic risk assessment considering HNS carried or not, and oceanographic and weather conditions.

ÆDemonstrate and support feasibility to increase infrastructures use and passage density capability by 20% on regulated areas based on a realistic risk assessment on infrastructure constraints and navigation conditions.

ÆProvide a navigation support tool to reduce human error and hence increasing safety in an increasing navigation density scenario and reducing collision, grounding and wake effect accidents by 20%.

ÆReduce waiting time and manoeuvring in ports, inland waterways and infrastructures accesses by 10% (with inherent reduction of energy and production of CO2).
