Marine Notice: Offshore Rock Placement In Corrib Gas Field

25th July 2017

#MarineNotice - Shell E&P Ireland advises that it will commence rock placement works between two wells in the Corrib Gas Field before the end of this month.

These works, which are expected to be completed by the middle of August, come after a recent pipeline survey and inspection that included the installation of a replacement subsea control umbilical.

The latter requires the placements of rocks for protection within the 500m safety zone along the corridor between wells P1 and P5.

There will also be installation of rock protection/stabilisation at areas of known exposure or excess spanning along both the infield flow and control lines as well as the 20” pipeline and main control umbilical between the gas field and landfall at Glengad.

Works will be carried out by the DP Fall Pipe Rock Placement Vessel Seahorse (Callsign PCAP), which will be listening on VHF Channel 16 throughout.

Full co-ordinates of the rock placements are detailed in Marine Notice No 31 of 2017, a PDF of which is available to read or download HERE.
