INTRODUCTION
1.1 PROJECT OVERVIEW
Public Natural Gas System Operator (DESFA) of Greece plans to install an N.G.T.S. Offshore Natural Gas Pressure Pipeline Varnavas-Karavos (Aliveri) whose purpose will be to supply natural gas to Evvia Island. The southern landfall in Attiki is named Varnavas while the previous names used for this landfall are Ag. Apostoli or Grammatiko. The northern landfall in Evvia is named Karavos which is also indicated as Aliveri landfall. The maximum water depth along the 20” Gas Pipeline route is approx. 70m (MSL).
Figure 1-1 – Natural Gas Pressure Pipeline Varnavas-Karavos route layout
1.2 PIPELINE SYSTEM DESCRIPTION The offshore pipeline system consist of an 20” Natural Gas High Pressure Pipeline from the battery limit at Varnavas landfall, Attiki to the battery limit at Karavos landfall at Evvia island. The length of the new 20” Natural Gas High Pressure Pipeline is about 14.2 km. The 20” Natural Gas High Pressure Pipeline will consist of the two offshore sections, joined together offshore by Above Water Tie In method. The Varnavas side offshore pipeline section commences at the KP -0.020 and finishes at AWTI Target point at KP 13.360 in water depth of 31.2m. Along the pipeline section route, maximum water depth is 70m. The Karavos side offshore pipeline section commences at the KP 14.205 and finishes at AWTI Target point at KP 13.360 in water depth of 31.2m. Along the pipeline section route, maximum water depth is 31.2m. Both pipeline sections will be manufactured from carbon steel with internal corrosion coating.

PROJECT OVERVIEW
Page 4 / 7
Public Natural Gas System Operator (DESFA) of Greece plans to install an N.G.T.S. Offshore Natural Gas Pressure Pipeline Varnavas-Karavos (Aliveri) whose purpose will be to supply natural gas to Evvia island. The southern landfall in Attiki is named Varnavas while the previous names used for this landfall are Ag. Apostoli or Grammatiko. The northern landfall in Evvia is named Karavos which is also indicated as Aliveri landfall. The maximum water depth along the 20” Gas Pipeline route is approx. 70m (MSL).
Figure 1-1 – Natural Gas Pressure Pipeline Varnavas-Karavos route layout 1.2
PIPELINE SYSTEM DESCRIPTION
The offshore pipeline system consist of an 20” Natural Gas High Pressure Pipeline from the battery limit at Varnavas landfall, Attiki to the battery limit at Karavos landfall at Evvia island. The length of the new 20” Natural Gas High Pressure Pipeline is about 14.2 km. The 20” Natural Gas High Pressure Pipeline will consist of the two offshore sections, joined together offshore by Above Water Tie In method. The Varnavas side offshore pipeline section commences at the KP -0.020 and finishes at AWTI Target point at KP 13.360 in water depth of 31.2m. Along the pipeline section route, maximum water depth is 70m. The Karavos side offshore pipeline section commences at the KP 14.205 and finishes at AWTI Target point at KP 13.360 in water depth of 31.2m. Along the pipeline section route, maximum water depth is 31.2m. Both pipeline sections will be manufactured from carbon steel with internal corrosion coating.
