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.

Ferry & Car Ferry News The ferry industry on the Irish Sea, is just like any other sector of the shipping industry, in that it is made up of a myriad of ship operators, owners, managers, charterers all contributing to providing a network of routes carried out by a variety of ships designed for different albeit similar purposes.

All this ferry activity involves conventional ferry tonnage, 'ro-pax', where the vessel's primary design is to carry more freight capacity rather than passengers. This is in some cases though, is in complete variance to the fast ferry craft where they carry many more passengers and charging a premium.

In reporting the ferry scene, we examine the constantly changing trends of this sector, as rival ferry operators are competing in an intensive environment, battling out for market share following the fallout of the economic crisis. All this has consequences some immediately felt, while at times, the effects can be drawn out over time, leading to the expense of others, through reduced competition or takeover or even face complete removal from the marketplace, as witnessed in recent years.

Arising from these challenging times, there are of course winners and losers, as exemplified in the trend to run high-speed ferry craft only during the peak-season summer months and on shorter distance routes. In addition, where fastcraft had once dominated the ferry scene, during the heady days from the mid-90's onwards, they have been replaced by recent newcomers in the form of the 'fast ferry' and with increased levels of luxury, yet seeming to form as a cost-effective alternative.

Irish Sea Ferry Routes

Irrespective of the type of vessel deployed on Irish Sea routes (between 2-9 hours), it is the ferry companies that keep the wheels of industry moving as freight vehicles literally (roll-on and roll-off) ships coupled with motoring tourists and the humble 'foot' passenger transported 363 days a year.

As such the exclusive freight-only operators provide important trading routes between Ireland and the UK, where the freight haulage customer is 'king' to generating year-round revenue to the ferry operator. However, custom built tonnage entering service in recent years has exceeded the level of capacity of the Irish Sea in certain quarters of the freight market.

A prime example of the necessity for trade in which we consumers often expect daily, though arguably question how it reached our shores, is the delivery of just in time perishable products to fill our supermarket shelves.

A visual manifestation of this is the arrival every morning and evening into our main ports, where a combination of ferries, ro-pax vessels and fast-craft all descend at the same time. In essence this a marine version to our road-based rush hour traffic going in and out along the commuter belts.

Across the Celtic Sea, the ferry scene coverage is also about those overnight direct ferry routes from Ireland connecting the north-western French ports in Brittany and Normandy.

Due to the seasonality of these routes to Europe, the ferry scene may be in the majority running between February to November, however by no means does this lessen operator competition.

Noting there have been plans over the years to run a direct Irish –Iberian ferry service, which would open up existing and develop new freight markets. Should a direct service open, it would bring new opportunities also for holidaymakers, where Spain is the most visited country in the EU visited by Irish holidaymakers ... heading for the sun!
