Hartshead Resources NL ( Hartshead , HHR or the Company ) is pleased to announce the issuance of the Invitation to Tender (ITT) for the Anning and Somerville Southern North Sea gas field production platforms. The ITT has gone out to four major, reputable fabricators with proven track records that pre-qualified through the HHR procurement process and marks a significant step forward in the journey towards first gas from the Company’s UK Southern Gas Basin assets.

The platforms will play a pivotal role in establishing Hartshead as a gas production company, enabling the Company to tap into the establish ed natural gas reserves in the license area and support the UK on its journey towards Net Zero.

The ITT package, containing comprehensive information about the project requirements, technical specifications, bidding procedures and evaluation criteria, requests proposals from the suppliers to provide an Engineering, Procurement, Installation and Commissioning (EPIC) service for the two platforms. The ITT process is expected to take several months prior to award of the contract, when the detailed engineering design of the platforms can begin.

Chris Lewis, CEO, commented: “I am thrilled to announce the issuance of the Invitation to Tender for the Anning and Sommerville Southern North Sea gas field production platforms. This is a significant advancement for Hartshead in progressing towards field development. We have carefully selected four reputable fabricators with proven track records to participate in the ITT process and we look forward to a rigorous evaluation process over the coming months, leading to the selection of a partner who will provide the EPIC service for the platforms.”

Prospective resources are estimated quantities of petroleum that may potentially be recovered by the application of a future development project(s) and relate to undiscovered accumulations. These prospective resources estimates have both an associated risk of discovery and a risk of development. Further exploration appraisal and evaluation is required to determine the existence of a significant quantity of potentially moveable hydrocarbons.
