SOCAR transports crude oil from Turkmenistan across the Caspian Sea in tankers to the BTC pipeline.
"Last year we transshipped approximately 4.2 million tons [of crude from Turkmenistan]. We expect this figure to be lower this year, but in 2020 I think it will be no less than 4 million tons," Nassirov said.
Azerbaijan is also looking to increase cooperation with other Caspian states, particularly on transportation, he added.
SOCAR also signed memorandum of understanding with Kazakhstan's KazMunaiGas earlier this year that envisages increasing cooperation on oil and gas production as well as transportation.
In the medium term this may include Kazakhstan resuming deliveries via the BTC pipeline network as oil production there grows.
The total length of the BTC pipeline is 1,768 kilometers, 443 kilometers of which passes through Azerbaijan, 249 through Georgia and 1,076 through Turkey. Construction of the pipeline was commenced in April 2003, and the pipeline was filled with oil on May 18, 2005.
