Zennor Petroleum Ltd. has progressed development of Finlaggan natural gas and condensate field in the central UK North Sea with the completion of the 2020 subsea installation campaign (OGJ Online, Aug. 2, 2018). Using three separate vessels mobilizations, the campaign was completed over the summer.
The Finlaggan manifold was installed adjacent to the two Finlaggan production wells (F1 and F2). The 145-tonne structure will allow well stream level metering to be conducted and provides potential tie-in points for additional wells and fields.
The 15 pipeline spools to provide final connections required at either end of the pipeline were all installed on the seabed and the 20 km pipe-in-pipe flowline from Finlaggan to the subsea isolation valve (SSIV) skid within the Britannia 500 m zone was dewatered.
At yearend, the development project will be over 90% complete and on target for first production in fourth-quarter 2021 following the rescheduled Forties Pipeline System shutdown in second-quarter 2021.
In this year’s third quarter, the company’s lenders agreed to upsize the existing senior secured term loan facility to fund the project to £185 million, and extend it by 1 year in line with the development schedule which had been revised as a result of COVID-19.
