PSE Kinsale Energy advises that it is engaging in works to decommission subsea wells at the Southwest Kinsale, Seven Heads and Ballycotton gasfields from this week for the next eight months.

Weather depending, advance works were set to begin between today, Monday 22 and Wednesday 24 March ahead of the arrival of the work vessel Stena Spey next month.

Stena Spey (callsign GCWP) is a Mobile Offshore Drilling Unit (MODU) which will be first deployed to the Southwest Kinsale Gasfield for a period of some 90 days, where it will be positioned using eight pre-laid anchors, before moving on to the Seven Heads field.

Anchor handling vessels MV Maersk Maker (callsign OZGO2) and MV Maersk Marine (callsign OWGQ2) will accompany the Stena Spey throughout the well abandonment campaign.

Other work vessels of note are the ad-hoc anchor handling vessel MV Maersk Lancer (callsign OUHX2) and standby vessel MV VOS Pathfinder (callsign 2ALO7). All will listen on VHF Channel 16 throughout the operation.

Further details on the campaign, including the locations of rigs and anchor positions, are included in Marine Notice No 12 of 2021, a PDF of which can be downloaded below.
