The Crux project will be developed to provide the primary source of backfill gas supply to the Prelude FLNG facility.
Activities relating to the development of the Crux field and surrounding reservoirs will be located in an area 30 km around the proposed platform. The project area also includes the 165 km pipeline which will connect Crux to the Prelude FLNG facility.
The front end engineering design (FEED) process is expected to start in 2019, with a final investment decision (FID) on whether to proceed anticipated in 2020.
It will take approximately 5 years for the platform to be fully designed, constructed off-site and transported to location.
The Crux project is expected to have a lifespan of at least 20 years. Future investment decisions may extend the life of the project.
Decommissioning will happen at the end of field operations.
The key execution stages of the project are:
- detailed design
- development drilling;
- installation of the platform;
- installation of the export pipeline and underwater systems to the platform facilities;
- commissioning and start-up;
- ongoing maintenance and operations; and
The key activities across the life of the project stages are summarised in the full Offshore Project Proposal Section 5.6, page 76.

Assessment of alternatives
Shell scoped a range of alternative options while developing the proposal for Crux as outlined in the full Offshore Project Proposal, Section 5.8, page 94.
This process concluded that the design for Crux presented within the Offshore Project Proposal is the most efficient and safest operating model for accessing the gas resource.
