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.
As of April 2021, the project has completed Front End Engineering Design (FEED) and is preparing to evaluate proposals for the Detailed Engineering and Execution phases, followed by the Final Investment Decision (FID). This is the current estimated timeline.
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.
