Made of 90,000 cubic meters of cement and 30,000 tons of steel reinforcement, the GBS was built at the Campamento construction site in the Bay of Algeciras in Southern Spain. The GBS is 180 mt. long, 88 mt. wide and 47 mt. high: larger than two soccer fields and as high as a ten-floor building most of which is The Terminal’s regasification plant is located under water. on the top of the GBS. It consists of four LNG Open-Rack vaporizers that operate using the LNG storage tanks natural heat of sea water, an energy recovery LNG vaporizer that reutilizes heat from the gas turbines, two cryogenic compressors, four pumps used to lift the LNG from the tanks, and five send-out pumps that send the gas through the vaporizers and into the external pipeline. The plant also includes a number of auxiliary facilities, such as gas turbine-powered electricity generators and the electrical control center. Inside the GBS are two LNG storage tanks, Berthing and unloading facilities each with a capacity of 125,000 cubic meters, made of steel with 9% nickel to provide cold temperature performance. Specially designed using ExxonMobil patented modular technology they were built at one of the world’s largest shipyards, in South Korea. For transport reasons, each tank was designed in 3 modular parts, which were then shipped to the Campamento construction site in Spain. There they were installed in the Terminal’s Gravity Based Structure using custom- The terminal also includes facilities for mooring designed systems and connected to each other and unloading LNG vessels. and the regasification plant by special welding techniques. Key components of the berthing facilities are the “Mooring Dolphins” constructed in the LNG is stored in the tanks at atmospheric Arsenale shipyard in Venice. These structures pressure and at the temperature of minus 162° C, are designed to safely accommodate a wide in order to keep it in its liquid form. range of different sized LNG carriers. veNice RoviGo cavarzere shore Base Minerbio adriatic LNG terminal Each Mooring Dolphin BoLoGNa structure consists of a base (reinforced concrete base slab, walls and roof slab approximately 7 meters tall), two reinforced concrete columns rising The Terminal crew’s living quarters, on the above base (approximately 28 meters tall) and other hand, include a fully staffed kitchen, a steel truss deck (63 meters long and 8,5 medical facilities, a laundry and heliport, as meters wide) sitting on top of the columns. well as communal areas for enjoying meals or The structures (9.000 tons each) were towed simply relaxing. for 50 kilometers from Venice to the Adriatic Sea, placed on the sea floor on both east and Pipeline west ends of the GBS and then connected to After being reconverted to its original state, the terminal by steel walkways. the gas then flows into the pipeline system, connecting the terminal with the mainland and In addition, for offloading LNG carriers the then with the national gas distribution network, terminal has installed specially designed ready to be distributed to end users. loading arms that can be connected and operated in a much wider range of sea states Designed and built by the Italian company consistent with an offshore location.
