A Volumetric Navigation System (VNS) started with great interest in new traffic navigation solutions considering certain scenarios in which all the vehicles share information in order to be part of a collaborative navigation network. In those scenarios, 3D volume dimensions are used to define the position of an associated volumetric envelope in time. In the maritime navigation the volume of the ship is the envelope of the ship after a given time.

Horizontal dimensions of this ships envelope will consider his current speed and also from his extreme stopping and manoeuvring capabilities from the given speed and load, and correction for the drift due to local measured wind and mapped currents. The vertical dimension in navigation at sea is the water distance below the keel at fore and the aft of the ship and the sea bottom as given by carthography and tide. The display may overlap the Electronic Chart Display and Information System (ECDIS) screen.VNS is a human error avoiding tool for collision avoidance, manouevring and navigation in low separation traffic lines and channels, crossings, port traffic, congested shallow waters.

The system key points are:
- Every vessel may be represented by a safety volume envelope which geometry will depend on its real shape, navigation and dynamical parameters and the surrounding environment;
- The position and course and heading of a vessel may be accurately calculated in real time from its position, speed and drift by GPS and GNSS technologies. Combining position, course, drift and volume, each vessel may be considered as a geo-referenced geometrical volume;
- In an scenario with different ship sizes and tonnage and speeds each vessel or boat generates his own volume that is transmitted to the other vessels in the area. The shore, docks river or channel sides and shallow water obstacles generate a warning when the volume of the vessel approaches at different levels of risk.

PROJECT GOALS:

The goal of the project ARIADNA is to design a new concept and build a new series of navigation support systems which facilitate:
- optimisation of the use of maritime and inland infrastructures,
- safe navigation in dense traffic situations in ports, rivers, channels, lock and port access areas,
- improvement of traffic separation schemes,
- improved risk control, including grounding,
- efficient and environmentally-friendly operations.
ARIADNA project reached his goals following a work package methodology, every one of them with clear objectives:

WP1 "State of the Art and User Requirements" which main objectives have been:
• To have a clear idea of the state of the art as regard current situation of navigation systems, related projects and programs as well as policies as regards navigation activities.
• To define the necessary requirements for the ARIADNA system, both from the functional and technical point view.

WP2 "System Engineering" governed the total technical effort to get the system requirements from the final users (customers) needs and to transform those requirements into a feasible system solution

WP3 "System Implementation" carry carried out the complete design and development cycle of an ARIADNA prototype with the previously designed architecture comprising each subsystem of ARIADNA system. Furthermore it was developed prototypes of one Local Control Station and two User Terminals as ARIADNA subsystems

WP4 "System Validation" had as objective to test and validate the ARIADNA system performance by means of a field test in a real-life environment under normal operations conditions. The validation exercises were executed in the Austrian Danube and in the Gibraltars strait and Algeciras Bay port (Spain).

WP5 "Implementation" assessed and facilitated the implementation of ARIADNA results on products and services, assessing economic potential, anticipating possible gaps, and facilitating administrative and customer acceptance.

All these work packages have been suppported by WP0 Management and WP6 Dissemination and Exploitation of the results.
The inland waterway and the maritime field tests, were necessary to demonstrate the performance of the ARIADNA system and provide navigation support to skippers to reduce the risk of collisions.

The system showed very clearly that potential collisions such as collisions with bridges, port infrastructure, and other vessels can be avoided due to the additional information, which the boat master receives. After the first trial, some parameters where adjusted, such as the risk factor, which was not available during inland waterway test. The captain of the vessel can change the risk factor depending on the situation between low risk, moderate risk, and high risk. Furthermore, the maximum prediction interval of the future position can be set according to the needs of the application.

The location for the maritime test was chosen very well since the port of Algeciras is located in a geo-strategic area of the Gibraltar Street, one of the most frequented navigable waterways in the world.

This demonstration validated the performance of the ARIADNA system in a port environment. The focus lied on providing navigation support to ship officers for port approach, port entrance and the navigation inside the port and in the TSS. The goal was to improve safety of navigation and improve shipping and port infrastructures efficiency (i.e. reducing waiting time at entrance and during manoeuvring). Enhancements in the ARIADNA software resolved the bugs detected during inland waterway test.

The second validation exercise (Gibraltars Strait) was a Live demostration of the ARIADNA system. Discussion about validation and future implementation of ARIADNA was held with the main stakeholders of the maritime community. Among the attendant there were representatives of IALA, General Directorate of Marine Merchant of Spain, Safe and Rescue Spanish Agency, EURMIG Association of European Recreational Craft Builder, trasmediterranea vessel ownership, Puertos del Estado Spanish Public Organism, Guardia Civil, Spanish navy, Port Authority of Sevilla, Algeciras, Valencia, Tanger MED, and Spanish VTS associations (Tarifa TRaffic)
