Abstract: | The short Baltic export route for Russian oil is an attractive source of supply for the European energy market. The article
examines the Russian oil export trade in the Baltic based on Automatic Identification System (AIS) data from 2005 matched
with supplementary data. The first part of the article gives a survey of activities and characteristics of 261 large crude
oil tankers, their flag states and owner countries. The second part views the data in the context of accidental oil spill
risk. Greek and Russian owners are leading carriers in this trade. Russia plays a double leading role as oil exporter and
shipowning country, securing major cargo shares for nationally owned vessels, while also giving a preferential spot in the
trade to Greek owners. Where environmental aspects are concerned, previous research has linked vessel characteristics with
the risk of casualty. Knowledge of flag, age, ownership and activity levels adds useful information about environmental risk.
The data show that flags associated with very high casualty or detention probabilities were represented by 18% of the activity
in this trade. Older vessels have a similar share, and at this particular time probably represent the more serious threat
of accidental oil spills. |
