<strong>Risk</strong> <strong>Analysis</strong> for <strong>Sea</strong> <strong>Traffic</strong> <strong>in</strong> <strong>the</strong> <strong>Area</strong> <strong>around</strong> <strong>Bornholm</strong><br />

2 Background<br />
2.1 Motivation<br />
In 2006, a new traffic separation scheme was <strong>in</strong>troduced <strong>in</strong> <strong>the</strong> waters between<br />
<strong>the</strong> Danish island <strong>of</strong> <strong>Bornholm</strong> and <strong>the</strong> Swedish ma<strong>in</strong>land (also known as <strong>Bornholm</strong>sgat).<br />
This scheme assigns separate lanes to each traffic direction and<br />
regulates <strong>the</strong> route geometry. The <strong>Bornholm</strong>sgat is used by <strong>the</strong> predom<strong>in</strong>ant<br />
part <strong>of</strong> all traffic between <strong>the</strong> Baltic <strong>Sea</strong> and <strong>the</strong> North <strong>Sea</strong> and is <strong>the</strong>refore<br />
heavily frequented.<br />
The first motivation <strong>of</strong> this report is to compare <strong>the</strong> situation before and after<br />
<strong>the</strong> <strong>in</strong>troduction <strong>of</strong> <strong>the</strong> traffic separation scheme. To this purpose, a comparative<br />
assessment is to <strong>in</strong>vestigate <strong>the</strong> change <strong>in</strong> risk. The focus is on risk to human<br />
life, environment and assets due to ship accidents.<br />
Fur<strong>the</strong>rmore, <strong>the</strong>re is an ongo<strong>in</strong>g issue concern<strong>in</strong>g <strong>the</strong> less <strong>in</strong>tensive, but never<strong>the</strong>less<br />
significant traffic from <strong>the</strong> Sou<strong>the</strong>ast Baltic <strong>Sea</strong>. This traffic orig<strong>in</strong>ates<br />
ma<strong>in</strong>ly from <strong>the</strong> ports <strong>of</strong> Gdańsk, Kal<strong>in</strong><strong>in</strong>grad and Klaipėda. In case <strong>of</strong> an oil<br />
spillage, sensitive ecosystems and recreational areas <strong>in</strong> Denmark, Sweden and<br />
Poland would possibly be affected.<br />
Here, <strong>the</strong> motivation is to evaluate <strong>the</strong> sensibility <strong>of</strong> a possible future traffic diversion.<br />
Aga<strong>in</strong>, a comparative risk assessment is to <strong>in</strong>vestigate <strong>the</strong> effect upon<br />
risk. In this case, <strong>the</strong> status quo needs to be compared to <strong>the</strong> situation that could<br />
be expected <strong>in</strong> <strong>the</strong> future after an eventual sea route has been <strong>in</strong>troduced.<br />
2.2 Target group<br />
The study aims to provide decision support to <strong>the</strong> Danish Maritime Authority<br />
(Søfartsstyrelsen), to <strong>the</strong> Royal Danish Adm<strong>in</strong>istration <strong>of</strong> Navigation and Hydrography<br />
(Farvandsvæsenet) and to <strong>the</strong> <strong>in</strong>volved Baltic <strong>Sea</strong> country authorities<br />
represented <strong>in</strong> <strong>the</strong> Hels<strong>in</strong>ki Commission (HELCOM).<br />
2.3 <strong>Risk</strong> concept<br />
In <strong>the</strong> present study, risk is understood accord<strong>in</strong>g to its classical def<strong>in</strong>ition <strong>in</strong><br />
