The Lampedusa Disaster: How to Prevent Further Loss of Life at Sea?

Coppens J.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2013

Vol. 7, no. 4

589--598

Lampedusa – an Italian island barely 70 miles from northern Africa and 100 miles from Malta – has become a gateway to Europe for migrants. In some seasons, boats filled with asylum seekers arrive almost daily. However, yearly, hundreds of people die trying to cross the Mediterranean Sea. This paper will deal with the obligations of States towards seaborne migrants, the question of why so many people die near Lampedusa and the possible solutions in order to prevent further loss of life at sea.

One of the primary sources of information and inspiration in the creation of new, more secure solutions in traffic organization are the occurrences with most serious consequences called accidents (air), serious accidents (rail) or catastrophes (road, sea). Accidents investigation is usually conducted in terms of searching for the reasons of these events and to make preventive recommendations aimed at elimination of these causes. In this paper, it is proposed to draw more attention to the events of somewhat less severity of the consequences - serious incidents (air), traffic conflicts (road) and incidents (rail, maritime). A model of real serious traffic incident, created with the use of stochastic, timed Petri nets is presented. Simulation experiments were carried out, which allowed for determination of the probability of transformation of the incident into the accident. The proposed method of analyzing serious traffic incidents also allows to determine the effectiveness of the barriers that have prevented an accident in a real occurrence.
