GE Powers Offshore Gravity-Based LNG Terminal

Posted on November 24, 2009

GE Oil & Gas technology is powering a gravity-based offshore LNG terminal located 17 kilometers offshore, near Venice, on Italy’s north east coast. The LNG terminal’s operations are powered by three GE10 low-emission gas turbines – two (2) GE10-1 single gas modules and one (1) GE10-1 dual fuel gas turbine, providing a total power output of 30 megawatts. All three units feature GE’s advanced Dry Low NOx (DLN) combustion system enabling the terminal to meet the stringent emissions reduction and environmental regulations prescribed by the Italian regulator.

Owned and operated by Adriatic LNG, the terminal is moored in waters 30-meters deep using an artificial island Gravity Based Structure (GBS) for offshore LNG. At the heart of this project is an enormous reinforced concrete box that rests on the sea floor and houses two LNG storage tanks. Overall, the facility is 375 meters long by 115 meters wide. The project marks the first offshore deployment of a GE10-1 ‘dual fuel low emissions’ gas turbine system.

This new terminal will increase Italy’s regasification capacity by 200%, is larger than two soccer fields, as high as a 10-story building and has two LNG tanks with a combined annual capacity of 8 billion cubic meters - representing around 10% of Italy's yearly gas demand. The Adriatic LNG operated terminal receives LNG shipments from Qatar (80%), Egypt and Trinidad (remainder) twice a week. The LNG is regasified at the terminal and then transported to an onshore metering station, before it enters Italy’s gas network.

GE Oil & Gas supplied the units to Aker Kvaerner Contracting International, Adriatic LNG’s primary contractor on the project. GE will maintain the terminal’s power plant equipment through an 18-year contract service agreement. Adriatic LNG is a joint venture between Qatar Terminal Limited (45%), a 100% owned Qatar Petroleum subsidiary, ExxonMobil Italiana Gas (45%) and Edison SpA (10%).
