Jedan od glavnih konkurenata PEOP-u je naftovod Burgas-Alexandroupolis, kojim bi se prenosila ruska nafta sa bugarske crnomorske obale do jedne grčke luke na sjeveroistoku Egeja.
One of the PEOP's main competitors is the Burgas-Alexandroupoli pipeline that would carry Russian oil from Bulgaria's Black Sea coast to a Greek port in the northeast Aegean.
