04 Aug 2023: The Offshore Petroleum Regulator for Environment and Decommissioning (“OPRED”) acting on behalf of the Secretary of State for Energy Security and Net Zero (“the Secretary of State”) is currently considering the Environmental Statement (“ES”) in relation to the project. The Secretary of State has requested additional information including; 1.With the uncertainties surrounding the project it is difficult to assess the impact. Please summarise the project as accurately as possible including updates since the ES was submitted and provide up to date impact assessments using this specific information. 2.Please clarify how power will be generated on the FPSO. If the import/export line does not go ahead or the OWT does not go ahead how will this impact atmospheric emissions? 3.Atmospheric emissions - please provide anticipated annual emissions from the project for the life of the field. 4.Please provide an analysis of carbon intensity of the proposed production at Avalon and a comparison between the different options for the project and other oil and gas projects in the UKCS. 5.'B1 - Nature of Project' - this section states the Avalon Field is expected to produce hydrocarbons for 10 years while text on page v-xiii states the Avalon Field Development is expected to produce hydrocarbons for 15 years. Please clarify 12. OWT - What is the expected downtime of the proposed turbine / turbines. How will power be generated during this time?
