DESCRIPTION
Revithousa island is storage for LNG- Liquefied natural gas. During the visit our NGS supplies, had a meeting with the operational manager of the site and agreed about cooperation for the Israeli market in case that it will be decided to build LNG terminal in Israel. This facility has been accomplished with the cooperation of many companies which NGS is representing: The design and the engineering was made by a team of international companies under the management of Asprofos engineering. A large amount of pipes were supplied by Corinth Pipeworks. Many of the ball valves and other equipment ware supplied and built by Enimex. In addition, Totgas supplied a lot of the necessary equipment during the constructions. The construction of the LNG unit was built by a group of the international companies including Greek contractors such as J&P Avax, Elter and others.

The Construction of the LNG Tanks Two full containment type (double shell) tanks located in pits excavated
in the hill of the island.
Inner container made of 9 % Nickel steel.
Outer container made of concrete.
Isolating material of 1 m thickness between inner and outer containers.
Support by 212 seismic isolating absorbers.
These supports can absorb movements of the tank (in a distance up to 30 cm) in any direction in case of an earthquake with max. horizontal
acceleration of a magnitude of 0,5 g.

At the same time, a 13MW High-Performance Combined Heat and Power (CHP) Unit is also in operation at the LNG facilities, applying innovative technology. This unit produces enough energy to cover the island’s needs with the most environmentally-friendly method. The surplus of electrical energy can by channeled to PPC’s network.All the produced heat is used for vaporizing of the L.N.G. before it is exported from the island to the consumers. In periods without heat demands the power plant can still produce electricity using the backup radiator cooling plant.
