Assessed multiple transport, power, and offshore infrastructure options to support a UK carbon storage licence submission, including technical, cost, safety, and emissions analysis
Motivation:
As part of the work programme for its UK carbon dioxide appraisal and storage licence, Goal7's client required a study into feasible transportation, power supply, and offshore infrastructure options for the development concept for submission to the NSTA.
Our Approach:
Five different cases were assessed on a technical, emissions, safety, and cost basis, with regular check ins arranged with the client to update on progress and ensure interfaces were carefully managed. To enable accurate assessment of the cases, the project team engaged with various vendors across the value chain to validate study findings and ensure study inputs were aligned with actual data.
An interim presentation of the study findings was shared with the client ahead of the project deadline to answer questions and update on final work scopes to be executed prior to the final report submission.
A final report was produced, which included, but was not limited to:
- Steady state flow assurance
- Offshore infrastructure requirements, including major equipment list, considering both pipeline and shipped transportation methods and the impact that each would have on the topsides
- Recommended power supply options for each case
- Major accident hazard assessment
- Reliability, maintainability and availability (RAM) assessment
- Greenhouse gas emissions assessment, encompassing the value chain elements within the study boundaries
- Class V cost estimates (CAPEX and OPEX) for the value chain elements within the study boundaries
- A comparison of each of the five cases, resulting in a final screening matrix to rank on technical, emissions, cost, and safety criteria
Benefit and Impact: The final report contributed to one of the deliverables set out in the work programme of the client's carbon dioxide appraisal and storage licence, whilst highlighting the feasibility and any red flags associated with the different cases assessed. Suggestions for areas of further study were also included to refine the outputs of the study throughout the appraise phase.
