Subsea Architecture Optimisation

Subsea Architecture Optimisation

Benefits

Atteris consolidated our Client’s array of future brownfield tie-back options, rapidly narrowing the number of future subsea architecture concept options to a shortlist of high value concepts that presented a simplified subsea architecture and overall cost reduction.

Background

The Client’s brownfield development plan includes various possible future phases, including tie-back of a new drill centre, tie-in of a compression facility (and its associated risers), and several subsea tie-backs from for various fields. The Client engaged Atteris to assess the proposed future tie-in strategies and architectures to determine the installability of the concepts and identify opportunities for simplification and cost reduction

Work Performed by Atteris

The scope included:

Concept identification and screening considering many future development options and various simplification initiatives.
Concept definition in each development phase to confirm concepts are technically and functionally feasible.
Concept definition of construction and installation activities, isolation of existing live facilities, pre-commissioning activities and start-up activities to demonstrate that each future development phase is installable.
