Abstract
This paper emanates from the European Research Project MarNIS. The
possibility of monitoring traffic has improved considerably since the introduction
of AIS (Automatic Identification System). A much better view of what is going
on at sea offers new possibilities to enhance shipping safety. The risk of each
ship delivers the basis for taking measures according to UNCLOS and the
precautionary principle, to ships that have a far more than average risk. The
application of this principle requires a scientific approach for the determination
of the risk and new operational tools.
The three main aspects necessary to implement risk analysis into the maritime
traffic to enhance safety at sea are described. Firstly, the legal basis – the need
for legal instruments, the definition of a high risk ship and new public
competences. Secondly, a mathematical model to determine the so-called risk
index for individual ships calculated dynamically, depending on the geographical
position, the ship characteristics, the environmental conditions, other ships,
shallows and other obstacles, such as offshore platforms and wind farms.
Thirdly, there is the operational application.
