Displaying items by tag: Rockabill Subsea Cable

The main lay installation works for the Rockabill Subsea Cable will take place from tomorrow, Saturday 20 July, to Sunday 1 September.

Using the vessel CS Teliri (callsign IBBT), the Rockabill cable system will be conducted from north of Lambay Island across the Irish Sea to Southport in England.

The cable itself is armoured and has an OD of 38mm. The cable ship will firstly clear the route of seabed debris with a grapnel before installing the cable.

During installation operations, the vessel will be moving slowly along the route while towing a sea plough to bury the cable into the seabed. During these works the vessel will have restricted manoeuvrability as it completes the work scope.

Deployed guard vessels will monitor the exposed areas of cable at crossing locations while burial progresses.

Ships are asked to avoid using anchors, bottom-trawl fishing and other seabed gear within half a mile of this cable route, and to maintain a safe distance from the cable ship during installation operations and that static gear be relocated from the route prior to commencement of operations.

Vessels are requested to pass at a safe speed and distance and fishing vessels are advised to remain a safe distance from the areas identified. Guard vessels will be deployed at certain cable crossing points to aid in monitoring the exposed areas and will advise of safe distances locally. The vessels will monitor VHF Channel 16 at all times.

The location co-ordinates of the operation are as included in Marine Notice No 24 of 2019, a PDF of which is available to read or download HERE.

Marine Wildlife Around Ireland One of the greatest memories of any day spent boating around the Irish coast is an encounter with marine wildlife.  It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. As boaters fortunate enough to have experienced it will testify even spotting a distant dorsal fin can be the highlight of any day afloat.  Was that a porpoise? Was it a whale? No matter how brief the glimpse it's a privilege to share the seas with Irish marine wildlife.

Thanks to the location of our beautiful little island, perched in the North Atlantic Ocean there appears to be no shortage of marine life to observe.

From whales to dolphins, seals, sharks and other ocean animals this page documents the most interesting accounts of marine wildlife around our shores. We're keen to receive your observations, your photos, links and youtube clips.

Boaters have a unique perspective and all those who go afloat, from inshore kayaking to offshore yacht racing that what they encounter can be of real value to specialist organisations such as the Irish Whale and Dolphin Group (IWDG) who compile a list of sightings and strandings. The IWDG knowledge base has increased over the past 21 years thanks in part at least to the observations of sailors, anglers, kayakers and boaters.

Thanks to the IWDG work we now know we share the seas with dozens of species who also call Ireland home. Here's the current list: Atlantic white-sided dolphin, beluga whale, blue whale, bottlenose dolphin, common dolphin, Cuvier's beaked whale, false killer whale, fin whale, Gervais' beaked whale, harbour porpoise, humpback whale, killer whale, minke whale, northern bottlenose whale, northern right whale, pilot whale, pygmy sperm whale, Risso's dolphin, sei whale, Sowerby's beaked whale, sperm whale, striped dolphin, True's beaked whale and white-beaked dolphin.

But as impressive as the species list is the IWDG believe there are still gaps in our knowledge. Next time you are out on the ocean waves keep a sharp look out!
