Hartshead Resources NL announced that the Company has awarded a contract for a Geophysical Survey across the Anning and Somerville fields and inter- field pipeline locations to GEOxyz UK Limited (GEOxyz), following a competitive tender and technical and commercial bid evaluation process. It is expected that the Geo Ocean III, a 77 metre second generation Dynamic Positioning (DP2) Multi-Disciplined Offshore Survey Vessel, with specialist deep-push Cone Penetration Testing (CPT) and vibrocoring capability, will be mobilised to the Anning and Somerville field locations in April 2023. The main objectives of the geophysical survey is to provide the Company with an interpretation of the seabed geomechanical and engineering conditions at the Anning and Somerville field locations as well as an environmental baseline survey and habitat assessment.

The survey will consist of the following components: A detailed analogue and 2D high resolution survey over a 1,000 metre x 1,000 metre square box centred on the Anning and Somerville jacket locations; A 400 metre X 400 metre more detailed analogue survey to inform the exact emplacement of the Anning and Somerville jackets; A 400 metre X 400 metre more detailed analogue survey to inform the exact emplacement of the Anning and Somerville jackets; Onshore and offshore laboratory testing of seabed samples taken during the sampling operations. The results of the Geophysical Survey will form part of the Environmental Statement which is a key component of the Field Development Plan (FDP) submission and is also required for the Platform Front-End Engineering Design (FEED) jacket design verification.
