Arcadia Valley Phase 1

We proposed a change to the basis of design and revised the electrical kiosk transformer arrangement from the original low-cost off-the-shelf kiosk arrangement to a higher specification kiosk arrangement. This revised kiosk arrangement decreased the power cable requirements, and resulted in a cheaper overall power network. Our NPV assessment over the lifecycle of the assets demonstrated that the revised kiosk arrangement ultimately resulted in a reduction in the total field cost of $3.4 million.

We also proactively developed a digital automated optimisation tool to further improve the network, resulting in reductions in the size and length of power cables and fewer kiosk transformers and other power network units.

In addition to financial benefits associated with decreased capital costs, the new kiosk arrangement improved safety on the project, by reducing arc flash hazard, lowering risk of electrocution and reducing requirements for personal protective equipment in the safer work environment.

The new arrangement also improved security of supply by decreasing the likelihood of nuisance tripping. It also improved the project’s carbon footprint by reducing the power system losses and quantity of materials.

All-in-all, the project is helping Santos to produce LNG in a safer, less emissions intensive and more cost-effective manner, and make its own contribution to the global carbon emissions effort.
