Corrib Gas Field Pipeline Survey, Maintenance & Engineering Works In July & August


#MarineNotice - Shell E&P Ireland Limited has begun a campaign of inspection of the Corrib Gas Field pipeline and associated infrastructure with repair and maintenance as required. Engineering tasks are also scheduled for well P3.

The near shore pipeline inspection was scheduled to commence in mid July and last for approximately 10 days. The offshore pipeline and subsea structure inspection along with the P3 work is due to commence in early August 2018 and last for approximately 14 days.

Visual and acoustic surveys will be conducted by means of sensors mounted on vessels and Remote Operated Vehicles (ROV) and cameras located on attendant survey vessels, ROVs and towed side scan sonar.

The near shore pipeline and umbilical sections will be inspected from the nearest point accessible inshore at high tide progressing to offshore until a suitable overlap with the offshore inspection is achieved.

The offshore inspection will commence at the Corrib field location and will continue towards shore until the vessel is required, on Marine Mammal Observer (MMO) advice, to relocate to the inshore inspection extent at safe navigation depth limit.

The vessel An Gearoidin (Callsign EIDL6) will undertake the near shore survey scope. All the equipment used will be vessel deployed. The Macbel and Blue Eagle will provide safety and welfare support to An Gearoidin.

The Siem Stingray (Callsign LAFP8) will undertake the deep water surveys and the subsea facilities maintenance and inspection. It will also carry out the P3 rectification work. All equipment used will be vessel and/or ROV mounted. All vessels will be listening on VHF Channel 16 throughout the project.

Full details of relevant co-ordinates and a map of the survey area are included in Marine Notice No 31 of 2018, a PDF of which is available to read or download HERE.
