Location map - Activity: Greater Western Flank Phase 2 Geotechnical Investigation (refer to description)

Woodside Energy Ltd proposes to undertake a small geotechnical survey in Quarter 4, 2015 to confirm the seabed type in the proposed Greater Western Flank Phase 2 (GWF‐2) pipeline location, and confirm the depth of overlaying sediment is suitable for installation of skirted foundation structures.
The proposed survey will be undertaken using a general purpose vessel approximately 60 – 100 m in length.
Key activities are as follows:
 In Situ penetration testing: to depths of between 1 – 3 m below the seabed;
Piston/push sampling: to depths of between 1 – 3 m below the seabed.
The proposed operational area is located in retention lease WA‐51‐R in Commonwealth waters,
approximately 135 km north‐west of Dampier. Water depths in the area range from approximately 65 – 95m.
Map has been extracted from Environment Plan submitted.
