#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.

Coastal Notes Coastal Notes covers a broad spectrum of stories, events and developments in which some can be quirky and local in nature, while other stories are of national importance and are on-going, but whatever they are about, they need to be told.

Stories can be diverse and they can be influential, albeit some are more subtle than others in nature, while other events can be immediately felt. No more so felt, is firstly to those living along the coastal rim and rural isolated communities. Here the impact poses is increased to those directly linked with the sea, where daily lives are made from earning an income ashore and within coastal waters.

The topics in Coastal Notes can also be about the rare finding of sea-life creatures, a historic shipwreck lost to the passage of time and which has yet many a secret to tell. A trawler's net caught hauling more than fish but cannon balls dating to the Napoleonic era.

Also focusing the attention of Coastal Notes, are the maritime museums which are of national importance to maintaining access and knowledge of historical exhibits for future generations.

Equally to keep an eye on the present day, with activities of existing and planned projects in the pipeline from the wind and wave renewables sector and those of the energy exploration industry.

In addition Coastal Notes has many more angles to cover, be it the weekend boat leisure user taking a sedate cruise off a long straight beach on the coast beach and making a friend with a feathered companion along the way.

In complete contrast is to those who harvest the sea, using small boats based in harbours where infrastructure and safety poses an issue, before they set off to ply their trade at the foot of our highest sea cliffs along the rugged wild western seaboard.

It's all there, as Coastal Notes tells the stories that are arguably as varied to the environment from which they came from and indeed which shape people's interaction with the surrounding environment that is the natural world and our relationship with the sea.
