 In the 19th century, the sharp increase in oil production in Baku gave a huge impetus to the development of shipping in the Caspian Sea, and as a result, there was a need to create fundamentally new floating facilities for the transportation of oil and oil products.Many of the islands along the Azerbaijani coast continue to hold significant geopolitical and economic importance because of the potential oil reserves found nearby.Bulla Island, Pirallahı Island, and Nargin, which is still used as a former Soviet base and is the largest island in the Baku bay, all hold oil reserves.
