Decmil - Pluto Site A Civil Works

The Woodside Pluto LNG Project comprises two 'greenfield' on-shore sites denoted as Site A and Site B. An existing haul road, running in an approximately north-south orientation, divides the two Sites: Site A is located adjacent the west side of this road and Site B is adjacent the east side.

Site B will contain the main process units and utilities associated with the LNG plant and Site A will contain storage tanks and associated utilities, import and export pipelines.

Construction activities include:

• In-situ reinforced concrete bund walls to three perimeter sides of Condensate Tank area, including a central dividing wall within the bund area
• Partial mass-concrete infill to trench beneath base of bund walls
• Pipe culverts situated close to north-west and north-east corners of Condensate Tank bunded area
• Pump pit adjacent west side Condensate bund
• In-situ concrete flare tower foundation
• Two Boil Off Gas (BOG) 'table top' in-situ concrete support structures including footing foundations
• Concrete footings with pedestals for stick built steel frame enclosure to BOG compressors
• Below ground cable installation, including pre-cast concrete lined cable trenches
• Concrete pad foundations with pedestals for support to pre-assembled multi tier structural steel pipe racks and other pre-assembly structures
• Concrete support for structural steel frame Analyser House
• Concrete and asphaltic paving to selected areas including backfill to suit required levels. Graded material topping to remaining areas
• Miscellaneous equipment footings
