Romania has commenced construction on a significant segment of the Neptun Deep offshore energy project, led by OMV Petrom and Romgaz. This initiative aims to establish a pipeline that will connect gas fields in the Black Sea with the mainland, facilitating increased natural gas production.
The proposed pipeline will stretch approximately 160 kilometers, linking offshore facilities to an onshore measurement and injection station located in Tuzla. The infrastructure will utilize thousands of steel segments, each with a diameter of around 76 centimeters, to ensure robust connectivity between production sites and the national transmission system.
OMV Petrom’s CEO Christina Verchere highlighted that the entire Neptun Deep project represents an investment of approximately €4 billion. Once operational, it is projected to deliver around 8 billion cubic meters of natural gas annually. The year 2026 is anticipated to be pivotal for project execution, as multiple offshore and subsea components are set to be installed concurrently, with production expected to commence in 2027.
The installation phase will involve extensive offshore operations supported by a fleet of roughly 50 vessels. These include specialized subsea construction ships tasked with welding, testing, and laying sections of the pipeline on the seabed. The initial vessel, Castoro 10, has already arrived at the site and begun preliminary work along the coastal area.
A microtunnel method will be employed for the pipeline’s landfall in Tuzla, aimed at minimizing environmental impact while enhancing operational safety. Romgaz CEO Răzvan Popescu emphasized that this milestone marks a crucial step in reinforcing both national and regional energy security through collaborative efforts.
The Neptun Deep project encompasses more than just the pipeline; it includes an offshore production platform, subsea systems, and a total of ten wells—some drilled in the Pelican South field while others are under development in the Domino area. An onshore control and metering station in Tuzla will complete this integrated production system, further supporting Romania’s energy landscape.
