Deepwater Platform Deployment for Black Sea Natural Gas Processing
OMV Petrom and SNGN ROMGAZ SA completed the installation of an offshore production platform to establish regional digital infrastructure and energy processing capacity in the Black Sea.

OMV Petrom and SNGN ROMGAZ SA have finalized the installation of the Neptun Alpha offshore platform for the Neptun Deep project in the Black Sea. The infrastructure supports deepwater extraction, gas treatment, and subsea integration for the Domino and Pelican South gas fields.
Joint Operational Framework and Roles
The project is executed as a joint venture between OMV Petrom and SNGN ROMGAZ SA to manage the engineering, fabrication, and marine installation requirements of the deepwater development. The complex operating environment in water depths of approximately 120 meters required combining technical resources for offshore logistics, subsea drilling, and transport infrastructure.
Fabriation of the platform components was handled by contractor Saipem across two facilities: the support jacket was fabricated in Arbatax, Italy, while the platform topsides were constructed in Karimun, Indonesia.
Platform Architecture and Technical Specifications
The Neptun Alpha platform functions as the central offshore hub for processing natural gas prior to onshore transmission. The combined structure weighs 16,500 metric tons and reaches a total height exceeding 225 meters.
Installation relied on the semi-submersible crane vessel Saipem 7000 for positioning and lifting. Technical parameters and structural specifications include:
- Foundation System: Eight steel piles, each exceeding two meters in diameter, driven into the seabed to anchor the jacket structure.
- Automation Standard: Fully automated topside processing units designed for remote operations without permanent on-site crew.
- Maintenance Logistics: Support via a dedicated operation and maintenance vessel capable of accommodating up to 90 personnel during service interventions.
Subsea Integration and Infrastructure Development
The platform interfaces directly with broader subsea production systems and transport networks. The complete offshore pipeline routing connects ten production wells across the Domino and Pelican South fields to subsea production systems and collector pipelines. Gas flows directly to the Neptun Alpha platform for processing before entering a 160-kilometer main offshore transport pipeline that delivers the gas directly to the onshore gas measurement station at Tuzla.
The 160-kilometer main pipeline connecting the offshore facility to the onshore terminal at Tuzla has been laid. To date, six of the ten planned development wells have been drilled. Next implementation phases involve completing the remaining wells, installing interfield subsea pipelines, and conducting integrated system commissioning tests prior to operational startup.
