Hartshead Completes Pipeline Route Survey

- The Pipeline Route Survey covering the offtake pipeline route for the Anning and Somerville field developments has been successfully completed with all objectives achieved.
- The Gardline “Ocean Observer” vessel completed the survey of the routes with no accidents or incidents.
- The survey data will now be analysed, with the results providing critical input to the Environmental Statement and a detailed understanding of the seabed conditions to assist in the pipelay for gas transportation.
- The Invitation to Tender for the Engineering, Procurement, Construction and Installation (EPCI) contract has been issued to five leading subsea contractors.

Hartshead Resources NL (Hartshead, HHR or the Company) is pleased to announce that the Company, in conjunction with joint venture partner RockRose (UKCS2) Limited (RockRose), has completed the pipeline route survey covering the offtake routes for gas production from the Anning and Somerville fields. The survey was conducted using the Gardline MV Ocean Observer over a period of more than a month with no safety issues or incidents and a large amount of seabed technical and environment data acquired.

All the objectives of the survey were met with over 1000 km of seismic lines run and 52 Cone Penetration Tests (CPT) and 23 Vibrocores taken to help define the seabed status, along with 27 seabed samples and camera transects to identify any habitats and provide input to the environmental baseline survey. The material recovered from the survey will undergo laboratory analysis in accordance with international standards and procedures, with the results expected to be reported early in 2024, and will provide input to the Environmental Statement for the Anning and Somerville development.

A full survey report is being prepared, elements of which will be used to support the Invitation to Tender (ITT) for the pipelines EPCI, which has been issued as per the development contracting plan, to 5 internationally recognised pipeline and subsea installation contracting companies.

Responses to the ITT are expected in the current quarter, which will then be evaluated as per internal Hartshead process ensuring a transparent, fair and competitive tender process. Tender award is expected in early 2024.

Keith Bush the Hartshead COO said, "We would like to thank the team involved in performing the survey work with extreme diligence and attention to safety, working in rapidly changing weather conditions and showing remarkable flexibility when changes to the programme were required. The data gathered will allow us to progress the Environmental Statement as planned and ensure that tenders for the pipeline contracts reflect the real conditions on the seabed.”
