The latest Marine Notice from the Department of Transport advises that Kinsale Energy’s well decommissioning operations at the Kinsale and Seven Heads gas fields will continue in June and July.

The Stena Spey mobile offshore drilling unit (callsign GCWP) is performing the campaign off the South Coast of Ireland with the rig to be positioned at various locations as outlined in Marine Notice No 38 of 2021, which can be downloaded below.

The Stena Spey is currently operating at the Southwest Kinsale Gas Field and will relocate to the Seven Heads Gasfield area in early July.

Pre-lay anchoring activities will get under way later this week (between 10-13 June) prior to the rig relocating to the Seven Heads Gasfield area. These will be conducted by anchor handling vessels MV Maersk Maker (callsign OZGO2) and MV Maersk Mariner (callsign OWGQ2).

Once the Stena Spey is moored at the Seven Heads location, a anchor handling vessel will be chartered to stay with the rig until the end of the campaign. In addition, the rig will retain its permanent standby vessel, the MV VOS Pathfinder (callsign 2ALO7) which will be in the field throughout all operations.

The work vessels will be listening on VHF Channel 16 throughout the operation. All other vessels, particularly those engaged in fishing, are requested to give the rig (and pre-laid anchor patterns) a wide berth and to keep a sharp lookout in the relevant areas.

Coordinates of the anchor positions and other details are included in the Marine Notice attached below.
