Project Overview
The Alexandroupolis Independent Natural Gas System (INGS) represents a cornerstone of regional energy security. This floating LNG terminal provides diversified gas supply routes for Southeast Europe, reducing dependence on traditional pipeline imports.
Our engineering team delivered critical design and supervision services for both the marine terminal and the 28-kilometer pipeline connecting to the national transmission system.
Strategic Importance
The terminal serves as a key entry point for LNG cargoes from global suppliers, offering:
- Supply Diversification: Access to worldwide LNG markets
- Regional Hub: Gateway for gas flows to Bulgaria and the Western Balkans
- Energy Security: Alternative supply route independent of existing pipelines
Technical Achievement
FSRU Integration
The project utilizes a converted LNG carrier as a Floating Storage and Regasification Unit, capable of:
- Receiving LNG carriers up to Q-Max size
- Continuous regasification at 5.5 billion cubic meters annually
- Emergency send-out capacity for peak demand periods
Pipeline Engineering
Our team designed the subsea and onshore pipeline system including:
- 24-inch diameter high-pressure pipeline
- Horizontal directional drilling under environmentally sensitive areas
- Advanced cathodic protection system for corrosion prevention
Environmental Considerations
The project incorporated extensive environmental protection measures:
- Marine mammal monitoring during construction
- Seabed habitat restoration post-installation
- Zero-discharge policy for terminal operations
