Woodside North West Shelf Civil Works

Having already completed a number of contracts for Woodside Energy (under the North West Shelf Venture) on the LNG Train 4 and LNG Train 5 projects, BGC Contracting was subsequently awarded additional contracts to carry out civil work in the surrounding Burrup Peninsula area, located in Karratha, Western Australia.

TSEP ROCK SUPPLY HEAVY LOADOUT FACILITY

The first civil works contract awarded was to construct a rock armour seawall, incorporating a land backed wharf, to facilitate loading of rock dumping barges from Dampier. The seawall was constructed using a combination of filter grade product sourced from within the TSEP (Truckline System Expansion Project) Quarry and rock armour was transported from the nearby WEL Quarry using off road dump trucks.

The seawall development was part of an overall proposal that received a CASE Environmental Award and a Woodside Energy Limited Award for Environmental Excellence.

BGC delivered all components on time and within budget.

PROPANE TANKS FOUNDATION

After the completion of the TSEP Rock Supply works, Woodside again engaged BGC to carry out further civil works to provide a rock plate foundation for a 200,000m2 propane storage tank at for an LNG Project, located at the Burrup Peninsula.

The scope of work involved removal of loose rock outcrop, drill, blast and excavation.

Strict controls were required when undertaking the work, especially during drill and blast operations, due to the proximity of LNG gas storage tanks and an operational gas processing plant. Blasts were limited in both size and powder factor, ensuring absolutely no flyrock and very low blast levels to protect brittle tank insulation layers and sensitive instrumentation.

The Burrup Peninsula is also an area of special environmental and aboriginal heritage significance which also required strict consideration. An Environmental Management Plan specific to the project requirements was created, and any rubbish generated by the project was placed in segregated bins for removal offsite. Liaison with the local Aboriginal community was also undertaken to move and subsequently replace a rock inscribed with a petroglyph which was too close to the excavation.

Environmental and Aboriginal Heritage plans were implemented successfully and client relations with local Aborigines were enhanced as a result.
