How does the LNG regasification process work?
The floating liquefied natural gas (LNG) regasification terminal operated by LNG Hrvatska d.o.o. utilizes a Floating Storage and Regasification Unit (FSRU) to convert cryogenic LNG into pipeline-quality natural gas. This process is critical for integrating the island of Krk into the broader European gas network, allowing for flexible supply management since the 2010s (LNG Hrvatska).
Storage and Regasification Infrastructure
The FSRU vessel features four dedicated storage tanks with a combined total capacity of 140,206 m³. These tanks maintain the natural gas in its liquid state at approximately -163°C, minimizing volume for efficient transport and storage. The regasification process is driven by three primary regasification units, capable of achieving a maximum output rate of 451,840 m³/h. This high throughput ensures that the terminal can meet peak demand periods in the Croatian and regional markets.
Heat Exchange and Seawater Cooling
The core of the regasification process involves heat exchange. Seawater from the Adriatic Sea is pumped into the system to warm the cryogenic LNG. To prevent freezing and optimize thermal efficiency, a glycol mixture is often used in the heat exchangers. As the LNG absorbs heat from the seawater, it transitions from liquid to gas, expanding significantly in volume. The warmed seawater is then discharged back into the sea, while the regasified natural gas is sent through the subsea pipeline to the shore.
Safety and Central Control
Operational safety is maintained through a sophisticated central control room that monitors all vessel and terminal parameters in real-time. The system tracks pressure, temperature, and flow rates across the storage tanks and regasification units. Safety protocols include automatic shutdown mechanisms and continuous gas detection systems to mitigate risks associated with the cryogenic and high-pressure environments. The FSRU design allows for modular expansion and maintenance, ensuring long-term operational reliability for the Croatian energy infrastructure.
What are the key components of the onshore terminal infrastructure?
The onshore infrastructure of the LNG Hrvatska terminal in Omišalj, Krk, is designed to handle the receipt, storage, and distribution of regasified natural gas. The facility includes a jetty head equipped with breasting and mooring dolphins to secure the floating storage and regasification unit (FSRU). Quick release hooks facilitate efficient mooring operations, while a 90-meter-long access bridge connects the jetty to the mainland, allowing for personnel and equipment movement. The connecting pipeline is a critical component, spanning 4.2 kilometers with a diameter of 1,000 millimeters. It operates at a pressure of 100 bar, ensuring efficient transport of natural gas from the terminal to the onshore grid.
