Pipeline Integrity ConfirmationIndependent Oil and Gas plc ("IOG" or the "Company"), the development and production focused Oil and Gas Company, is pleased to provide an update on operations to confirm the integrity of the Thames Pipeline – a key step in its Southern North Sea dual gas hub development project.
- Cut section analysis confirms that the offshore section of the pipeline is in excellent condition.
- Inspection of the Bacton end of the pipeline is planned in the coming weeks to inform a planned elevated pressure hydrotest which will complete integrity confirmation.
- Further intelligent pig run now not expected to be required until shortly before first gas.
- FID now targeted for end September 2018.
- Updated Corporate Presentation added to website.
Further to the announcement made by the Company on 5 June 2018, IOG has been in detailed consultations with regulatory authorities on the necessary steps to re-commission the Thames Pipeline. Analysis undertaken by Oilfield Testing Services (OTS) on behalf of IOG of the three 12-metre sections retrieved from the 60km offshore point during offshore operations in May 2018 has enabled a recalibration of the predicted internal corrosion. This shows the pipeline’s condition can be considered practically ‘as new’.
Under the new pipeline integrity confirmation plan, IOG will run a crawler based measurement device from the Bacton terminal to approximately 1km offshore to assess the line’s internal condition. This is the section that, if any, would have been at a higher risk of degradation since decommissioning in 2015. Analysis of this data, along with the new corrosion baseline, will allow the Company to determine the safe maximum pressure of the subsequent 24-hour hydrotest that is required under the Pipeline Code. These operations are expected to occur during July and August 2018.
In this context, a further intelligent pigging run is not expected to be required until the line is recommissioned shortly before First Gas. By that time, the Thames Pipeline will run continuously from the Southwark platform to Bacton following the addition of a 7km 24-inch extension. An intelligent pig would then be run to inform future pipeline integrity management along the entire length of the export route.
In addition to significant cost savings, this optimised programme is also expected to minimise the impact on project schedule from the inconclusive intelligent pigging operation. This is expected to be limited to a matter of weeks, with FDP approval now targeted for the end of September 2018. Following that IOG expects to commence the process of full and safe recommissioning to export its 303 BCF of 2P gas reserves across five proven fields and additional 314 BCF of development and appraisal assets.
Updated Corporate Presentation
IOG is also pleased to announce that an updated version of its corporate presentation has been uploaded to the Company’s website.
Andrew Hockey, CEO of IOG commented:
We are now implementing an optimised programme to provide full and conclusive confirmation of the integrity of the Thames pipeline. Thanks to some excellent work by the IOG team and support of the regulatory authorities, this does not require an intelligent pig re-run in the short term. This has helped to protect our timeline to FID which in turn ensures that we keep the overall project on schedule to hit First Gas in late 2019.
