The work, due to commence in mid June and last for around 40 days, will include inspection of the offshore pipeline and subsea structure, inspection of the near shore pipeline, an umbilical lay at well P5, and a pipeline integrity test via ‘intelligent pig’ survey.
Visual and acoustic surveys will be conducted by means of vessel- and ROV-mounted sensors and cameras located on attendant survey vessels, ROVs and towed side scan sonar.
The Subsea Viking (callsign LJJL3) will undertake the deep water surveys and the subsea facilities maintenance and inspection. It will also carry out the umbilical lay and the intelligent pigging operation. All equipment used will be vessel and/or ROV mounted.
The An Gearoidin (callsign EIDL6) will undertake the inshore survey scope. All the equipment used will be vessel deployed.
Both vessels will be listening on VHF Channel 16 throughout the project.
