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.

Naval Visits focuses on forthcoming courtesy visits by foreign navies from our nearest neighbours, to navies from European Union and perhaps even those navies from far-flung distant shores.

In covering these Naval Visits, the range of nationality arising from these vessels can also be broad in terms of the variety of ships docking in our ports.

The list of naval ship types is long and they perform many tasks. These naval ships can include coastal patrol vessels, mine-sweepers, mine-hunters, frigates, destroyers, amphibious dock-landing vessels, helicopter-carriers, submarine support ships and the rarer sighting of submarines.

When Naval Visits are made, it is those that are open to the public to come on board, provide an excellent opportunity to demonstrate up close and personal, what these look like and what they can do and a chance to discuss with the crew.

It can make even more interesting for visitors when a flotilla arrives, particularly comprising an international fleet, adding to the sense of curiosity and adding a greater mix to the type of vessels boarded.

All of this makes Naval Visits a fascinating and intriguing insight into the role of navies from abroad, as they spend time in our ports, mostly for a weekend-long call, having completed exercises at sea.

These naval exercises can involve joint co-operation between other naval fleets off Ireland, in the approaches of the Atlantic, and way offshore of the coasts of western European countries.

In certain circumstances, Naval Visits involve vessels which are making repositioning voyages over long distances between continents, having completed a tour of duty in zones of conflict.

Joint naval fleet exercises bring an increased integration of navies within Europe and beyond. These exercises improve greater co-operation at EU level but also internationally, not just on a political front, but these exercises enable shared training skills in carrying out naval skills and also knowledge.

Naval Visits are also reciprocal, in that the Irish Naval Service, has over the decades, visited major gatherings overseas, while also carrying out specific operations on many fronts.

Ireland can, therefore, be represented through these ships that also act as floating ambassadorial platforms, supporting our national interests.

These interests are not exclusively political in terms of foreign policy, through humanitarian commitments, but are also to assist existing trade and tourism links and also develop further.

Equally important is our relationship with the Irish diaspora, and to share this sense of identity with the rest of the World.
