Rig Returns in Dublin Bay: Not for Oil but for Preliminary Sewage Pipeline Work

#DUBLIN BAY RIGS – The jack-up rig Excalibur returned to Dublin Bay yesterday, having previously carried out preliminary bore test-site drilling work last year for a new sewage pipeline. As reported last year the sight of several floating structures gave the distinct impression that oil had been struck and again the presence of the rig's purpose is further from true with no such oil-exploratory activity taking place, writes Jehan Ashmore.

The rig is in Dublin Bay for several weeks and is to carry out further site investigation to ascertain the most suitable route of a new under the seabed laid sewage pipeline for the €220m Dublin Bay Project, where the principle contractor for the project is Fugro Seacore.

According to Dublin City Council, the impact of the new outfall location on the outer fringe of Dublin Bay will be 'localised'. They also claim that the project is to further improve water quality in Dublin Bay. Under the terms of the waste-water discharge license issued by the EPA, the pipeline must be completed by 2015.

Currently wastewater is discharged at Ringsend where the the Wastewater Treatment Plant in processes a 1.9m population equivalent. The new outfall pipe and associated works is to address increased demand and will be able to increase the capacity to a 2.1m population equivalent.

The Excalibur was towed from Holyhead by the tug MTS Valiant, to a position close to the Dublin Bay Buoy, the primary navigational mark which acts a 'round-about' for shipping using Dublin Port. The Excalibur is essentially a large barge with several sea-legs than can be lowered onto the seabed, where upon the barge itself rests while hoisted above the waterline.

On board is a crane, porta-cabin like facilities for crew, a service workboat and a lifeboat. During the construction process there will be a guard-boat which will monitor other shipping activity, as a safety precaution. One of the first vessels to pass Excalibur was the 113,000 tonnes giant cruiseship Carribean Princess which edged cautiously by while outward bound yesterday for Belfast.

The treatment plant in Ringsend was built in 2003, in which the superior plant replaced an older facility closer to the Poolbeg Harbour at the foot of the now disused ESB Power Station. Up until then, two-thirds of the greater Dublin region was treated but only at this primary level where 60% of waster-water went straight through the facility into the Liffey, the balance of 40% had polluntants removed to form sludge which was disposed out at sea.

This uneviable of tasks was performed by the wastewater disposal vessel Sir Joseph Bazalgette (1963/2,258grt) which saw some 40m gallons discharged into the spoiling grounds off Dublin Bay and Kish Lighthouse.

The former London County Council commissioned vessel worked on the Thames until sold to Dublin Corporation. On occasions she would head back to port via a transit of Dalkey Sound.

Despite her sale to overseas buyers in 1999, she remains one of the largest vessel's in modern times to make a passage of the sound that marks the southern approaches to Dublin Bay.

Drilling of Test Boreholes in Dublin Bay

A jack-up rig barge has been positioned off the South Wall, Dublin Port, writes Jehan Ashmore.

The barge is contracted to Dublin City Council for the drilling of test boreholes in the approaches to and within Dublin Bay in relation to the Ringsend Wastewater Treatment Plant. Both jack-up barges 'Aran 250' and 'Excalibur' will be operating on a 24-hour / 7 days per week basis.

In attendence Sea Safari Tours RIB 'James Joyce', which normally operates as a tourist-sightseeing craft will act as a stanby boat during the rig operations. In addition a buoy will be positioned 300-metres of the barge during drill operations, which is expected to take approximately one week for each drill.

The project will also see the tug, Trojan providing supplies and to tow the jack-up rigs between locations in Dublin Bay. Both the James Joyce and the Trojan will be based out of the Poolbeg Marina, in the centre of the port.

Since the start of October, the project has also required the services of the yellow-hulled catamaran, Xplorer to carry out a bathymetric survey of Dublin Bay.

Underwater Dublin Bay Survey to Start on Friday

An underwater survey of Dublin Bay is expected to commence this Friday, (1st October 2010). It is part of a Dublin City Council (DCC) project to upgrade the Ringsend Wastewater Treatment Plant. Preliminary works will include a Bathymetric Survey of Dublin Bay and its approaches and last for a period of approximately one month. The area to be surveyed is attached in a Notice to Mariners issued by Dublin Port Company. The survey will be carried out by a 12 metre yellow hull catamaran "Xplorer". The "Xplorer" is fitted with A.I.S.

Volvo Dun Laoghaire Regatta

From the Baily lighthouse to Dalkey island, the bay accommodates six separate courses for 21 different classes racing every two years for the Dun Laoghaire Regatta.

In assembling its record-breaking armada, Volvo Dun Laoghaire regatta (VDLR) became, at its second staging, not only the country's biggest sailing event, with 3,500 sailors competing, but also one of Ireland's largest participant sporting events.

One of the reasons for this, ironically, is that competitors across Europe have become jaded by well-worn venue claims attempting to replicate Cowes and Cork Week.'Never mind the quality, feel the width' has been a criticism of modern-day regattas where organisers mistakenly focus on being the biggest to be the best. Dun Laoghaire, with its local fleet of 300 boats, never set out to be the biggest. Its priority focussed instead on quality racing even after it got off to a spectacularly wrong start when the event was becalmed for four days at its first attempt.

The idea to rekindle a combined Dublin bay event resurfaced after an absence of almost 40 years, mostly because of the persistence of a passionate race officer Brian Craig who believed that Dun Laoghaire could become the Cowes of the Irish Sea if the town and the local clubs worked together. Although fickle winds conspired against him in 2005, the support of all four Dun Laoghaire waterfront yacht clubs since then (made up of Dun Laoghaire Motor YC, National YC, Royal Irish YC and Royal St GYC), in association with the two racing clubs of Dublin Bay SC and Royal Alfred YC, gave him the momentum to carry on.

There is no doubt that sailors have also responded with their support from all four coasts. Running for four days, the regatta is (after the large mini-marathons) the single most significant participant sports event in the country, requiring the services of 280 volunteers on and off the water, as well as top international race officers and an international jury, to resolve racing disputes representing five countries. A flotilla of 25 boats regularly races from the Royal Dee near Liverpool to Dublin for the Lyver Trophy to coincide with the event. The race also doubles as a RORC qualifying race for the Fastnet.

Sailors from the Ribble, Mersey, the Menai Straits, Anglesey, Cardigan Bay and the Isle of Man have to travel three times the distance to the Solent as they do to Dublin Bay. This, claims Craig, is one of the major selling points of the Irish event and explains the range of entries from marinas as far away as Yorkshire's Whitby YC and the Isle of Wight.

No other regatta in the Irish Sea area can claim to have such a reach. Dublin Bay Weeks such as this petered out in the 1960s, and it has taken almost four decades for the waterfront clubs to come together to produce a spectacle on and off the water to rival Cowes."The fact that we are getting such numbers means it is inevitable that it is compared with Cowes," said Craig. However, there the comparison ends."We're doing our own thing here. Dun Laoghaire is unique, and we are making an extraordinary effort to welcome visitors from abroad," he added. The busiest shipping lane in the country – across the bay to Dublin port – closes temporarily to facilitate the regatta and the placing of six separate courses each day.

A fleet total of this size represents something of an unknown quantity on the bay as it is more than double the size of any other regatta ever held there.
