Chernomortransneft Begins Revamping of Standby Service Tunnel Through Markotkh Ridge

Date of publication: 11 June 2019 Print

Chernomortransneft has begun the removal of process pipelines in the Grushovaya – Sheskharis backup tunnel, which is currently out of service, as part of the comprehensive revamping programme currently being implemented at Sheskharis transshipment complex (TC).

Dismantling of the process pipelines in the Grushovaya – Sheskharis tunnel is the first stage in revamping the backup facility. A total of 54 kilometres of process pipelines will be removed by specialists. The pipes will be pulled out of the tunnel using a hoist installed at the northern portal of Sheskharis TC, cut into sections and removed from the site.
The first stage of the revamping of the tunnel is scheduled to be completed in February 2020.

The next stage of the revamping implies laying new pipelines with a higher throughput capacity. Respective works are scheduled for 2026.

For reference:

The service tunnel was built in 1967 and used for transportation of oil and petroleum products to the berths of the Sheskharis oil area. The tunnel is currently overaged in the context of its operational life. In 2015, when a new maintenance-free tunnel laid through Markotkh Ridge parallel to the old one was commissioned, the old tunnel was put out of service for further revamping.
