The jack up barge Aran 250 has been positioned in Dublin bay to carry out Borehole Drilling. The work is part of a Dublin City Council (DCC) project relating to the Ringsend Wastewater Treatment Plant. It will involve the use of either the jack-up barge "Aran 250" or "Excalibur".

These jack-up barges will be used for the drilling of test boreholes at various locations within Dublin Bay and its approaches. Initially, the "Aran 250" will be used and it is expected that under normal conditions it will operate on a 24 hour / 7 day week basis.

At all times when the jack-up barge is on location it will transmit an "AIS" signal. By night the barge will display white lights (operated in unison) flashing Morse code (U) every 15 seconds. These will be located at each corner. The barge itself will be lit by operational deck lights.

When the jack-up barge is operational it will have the standby boat "James Joyce" with two people on board in attendance. They will tie-up to a buoy moored approximately 300 metres away from the barge. The small tug "Trojan" will operate as a supply boat and will be based at the Poolbeg Marina. The Trojan will also be used for towing the barge from one location to the next.

The test borehole drilling positions (WGS 84) are as follows :-

Each location will take approximately 1 week to drill. Drilling will not follow in sequence listed above. VTS will keep all shipping advised with regards to the location at which the barge is operating.

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.
