First technical activities for IGB filling completed

By Trend

Preparations for the commercial launch of the Interconnector
Greece-Bulgaria (IGB) are actively progressing, and since mid-June
tests with quantities of natural gas have been underway along the
182-kilometer route of the interconnector, the ICGB AD, a project
company, told Trend.

Reportedly, the test volumes are currently 3,700,000 cubic

“In the first phase of the tests, the gas is supplied in stages
in the direction from Stara Zagora – Komotini. All sections are
purged with nitrogen in advance in order to prevent moisture and
oxygen remaining in the pipeline. This is one of the mandatory
technical requirements for the preparation of infrastructure for
commercial operation.

During this stage of the tests, the entire pipeline operates
under pressure, which is gradually being increased in accordance
with the approved test procedure. The pressure at which the
facility will be operating after the start of commercial activities
varies depending on the quantities of transported natural gas for
the respective day. The IGB pipeline is designed to operate at a
maximum pressure of up to 75 bar,” said the company.

The IGB project is of key importance for increasing security of
supply and for ensuring diversification of natural gas sources for
Bulgaria and the region of Southeast Europe. At the regional level,
IGB will provide access to the gas transmission network for
Bulgarian municipalities and regions that didn’t have an option for
connectivity. The interconnector with Greece is an entirely new
route for the transmission of natural gas to Europe and will give
Bulgaria and the region access to supplies from new sources. The
project will connect the country with the Southern Gas Corridor and
has excellent synergy with other major energy projects such as TAP,
TANAP, EastMed and the LNG terminal at Alexandroupolis.
