The main port at Turkmenbashi on the Caspian Sea is being renovated. Main shipping lines cross the Caspian to Astrakhan in Russia and Baku in Azerbaijan. Smaller Caspian ports are Alaja, Chekelen, and Ekarem. Plans call for expansion of Ekarem into a second major Caspian port. In 2006 Turkmenistan had eight merchant marine vessels of more than 1,000 tons displacement, of which four were cargo ships, two were oil tankers, one was for refrigerated cargo, and one was a combination ore and oil ship.
