## Engineering interpretation

Engineering interpretation: the variation expands an existing EPC relationship and should be understood as additional scope, while the 7.5 Mtpa figure is a plant target rather than demonstrated throughput. Integration with the Stage 1 works is a key delivery interface.

## Delivery responsibilities

An EPC reference defines a contracted combination of engineering, procurement and construction. Its boundaries still matter: field facilities, pipelines and utilities may be one package within a larger development. Construction affiliates and specialist subcontractors retain their stated roles. Quality records, pressure tests, pre-commissioning and handover need to match the actual facilities delivered. A historical project schedule does not become a publication date or establish today’s production. The reference documents the listed work rather than attributing all output, ownership or operation of the wider development to the contractor.
