Levels

On 9 October 2013 minister Brian Hayes spoke in the Dáil about Shannon water levels, saying:

A meeting between the ESB, Waterways Ireland and the Office of Public Works to review the interim operating regime is due to take place shortly.

On 17 and 18 October 2013, in correspondence with Waterways Ireland, I learned that the meeting had not then taken place and that no date had been set. I have now sent WI another note asking whether the meeting has been held and, if it has, requesting a report on the proceedings and outcome.

In the meantime, I have put together two charts nicked from waterlevel.ie for Banagher and Athlone:

Athlone and Banagher water levels

Athlone and Banagher water levels

Both of them show the levels for the last 35 days. I’m sure that more data and much more sophisticated analysis would be required to reach any reliable conclusion, but my untutored impression is that, in what has been a fairly dry autumn, keeping Lough Ree low didn’t do much to keep Banagher low. If that is so, and if I’m right in thinking that this autumn was dry (see below), the outcome would not show whether lowering Lough Ree would help in a very wet season; it may be necessary to repeat the experiment next year while performing rain dances. I would be glad, though, to have comments from more erudite folk and, if I get any information from TPTB, I’ll publish it here. In the meantime, this CFRAM PDF provides background reading.

On the dryness: Met Éireann’s monthly report for September 2013 is headed “Dry everywhere; warm and dull in most places” while that for October says “Rainfall was above average except in parts of the West, Northwest and North”. Its report doesn’t, AFAIK, specify any stations in the Shannon catchment (apart from Shannon Airport), but those to the west were generally below average while whose to the east were above; it may be that the Shannon rainfall was moderate.

Meath River Rescue

I have no idea what this Dáil written question and answer, from 12 November 2013, are about:

Peadar Tóibín [SF, Meath West]: To ask the Minister for Environment, Community and Local Government if his Department will provide direction for a safety procedure (details supplied) to be enforced; if this procedure been enforced in any other region or with any other community organisation; if he will reverse this decision and allow for Meath River Rescue to operate in a fully integrated and efficient manner.

Phil Hogan [FG, Carlow-Kilkenny; Minister for the Environment, Community and Local Government]: My colleague, the Minister for Transport, Tourism and Sport is the Minister with responsibility for receiving calls for assistance for inland waterways and mobilisation of appropriate response services. I have no function in the matter referred to in this question.

Googling suggests that Meath River Rescue got €278,358 for a boathouse and training room in Navan, with two FG TDs announcing the grant a year apart [or is one of those dates a typo?]. The service is known to Irish Water Safety but is not one of its Community Rescue Boats Ireland so it’s not a Coast Guard declared resource [which doesn’t mean there’s anything wrong with it]. Meath River Rescue’s own website and facebook page don’t seem to have been updated since April 2012 [although I am unfamiliar with facebook and may not be interpreting the dates correctly] but the service has been in action as recently as September 2013.

Unfortunately “details supplied” means supplied to the minister, not to readers of Dáil proceedings, so I have no idea what problem was being raised.

 

 

 

Ticking all the boxes

Sometimes an idea comes along that is just so good, so right, so advantageous on all counts that it is simply irresistible. This idea comes from the Americas, from the US Coast Guard. Adapted to the Irish inland waterways, and specifically to the Shannon, it could:

  • help to promote industry in recession-hit rural areas
  • create direct employment
  • help to stimulate indirect employment
  • promote Irish energy independence by reducing reliance on imported hydrocarbons
  • counter pollution of water-courses
  • reduce the number of heavy trucks using remote rural roads
  • use environmentally-friendly water transport, by barge along the Shannon
  • honour and promote the industrial heritage of Co Leitrim and the transport heritage of the Shannon
  • help to defray the costs of maintaining the Shannon Navigation
  • solve Dublin’s water supply problem, at least for non-potable water.

How could anybody resist?

The US Coast Guard has proposed that wastewater from fracking [PDF] should be transported by barge, rather than by truck or railway train, from the fracking sites to remote storage or treatment facilities. So, when fracking begins around Lough Allen, the wastewater could be carried down the Shannon by barge and, if necessary, pumped to Dublin.

It sounds like a winner to me.

Bolshevism, boats and bridges

The balance bridge crossing the canal, near Newcomen-bridge, as designed and erected under the superintendence of Mr Bindon Stoney, engineer of the Dublin Port and Docks Board, has been completed, and adds considerably to the facilities for carrying on the traffic. This bridge has been erected in substitution of a lift-bridge, constructed in 1872, but to which an unfortunate accident occurred in February, 1878.

Ralph S Cusack, Chairman, in the report of the Directors of the Midland Great Western Railway, 19 February 1879, quoted in the Freeman’s Journal 27 February 1879

In mid-October I mentioned that Maureen O’Sullivan [Ind, Dublin Central] had asked the unfortunate Jimmy Deenihan [FG, Kerry North/West Limerick, and minister for waterways] about Effin Bridge, the lifting railway bridge below Newcomen Bridge on the Royal Canal in Dublin. The bridge is lifted, to allow boats through, on [IIRC] one Saturday each month in the summer, making five lifts a year. Waterways Ireland says on its website [click Bridges if necessary]

The Newcomen Lift Bridge in Spencer Dock is owned and operated by Irish Rail, and requires a rail possession to be lifted. It can only be lifted for boats at limited prearranged times organised with Waterways Ireland. For details of opening times and to arrange passage contact the Eastern Regional Office on 01 868 0148.

Maureen O’Sullivan wanted

… a meeting of interests concerned with the operation of the lifting bridge with a view to devising a management and operational system that is less hostile to the use of the waterway as currently it is an impediment and discouragement to navigation on the Royal Canal and an obstacle to navigation-communication between the Royal Canal and River Liffey and between Royal Canal and Grand Canal at their eastern reaches […].

Jimmy Deenihan said

The bridge is operated by Irish Rail staff on a request basis at Waterways Ireland’s expense.

However, he wasn’t giving any hostages to fortune by making rash promises or even by commenting on whether the bridge was an impediment to navigation. But Ms O’Sullivan was undeterred: she returned to the topic with two written questions on 5 November 2013 and a priority question, no less, on 7 November 2013 [for certain values of “priority”]. On 5 November she asked two questions of Jimmy Deenihan

To ask the Minister for Arts, Heritage and the Gaeltacht further to Parliamentary Question No. 59 of 16 October 2013, the extent of railway track that needs to be closed by Irish Rail in order for a vessel on the Royal Canal, Dublin, to be given access between the First and Sea Levels of the Royal Canal; if there has been an assessment of whether the extent of track closure could be reduced to facilitate greater ease of navigation on the Royal canal; and if he will make a statement on the matter.

To ask the Minister for Arts, Heritage and the Gaeltacht further to Parliamentary Question No. 59 of 16 October 2013, if the option of a introducing a drop lock to replace the need of the lifting bridge has been considered since the establishment of Waterways Ireland or if that assessment was made by Waterways Ireland’s predecessors; the level of use of the sea level assumed in relation to the assessment; if the impact of the Spencer Dock Greenway was taken into account and vice versa, was account taken of the impact on the Greenway were the sea level to be made accessible to navigation by replacing the lifting bridge; if the assessment includes analysis of whether the effective re-opening of the sea level of the Royal Canal to meaningful levels of year-round traffic would be consistent with the EU’s commitment to the ‘protection and preservation of cultural heritage, in view of the fact that Dublin’s waterway’s heritage is part of the cultural infrastructure of Europe, contributing to economic attractiveness, job opportunities and quality of life; and if he will make a statement on the matter.

The ever-patient Mr Deenihan replied:

I am advised that the option of constructing a drop lock to replace the need for the lifting bridge at the location in question has been considered by Waterways Ireland but it was not deemed viable due to the estimated costs involved, given that the minimum cost for a drop lock to replace the bridge would be of the order of €5m. Work to install a drop lock at this location would also involve considerable temporary works, the extent of which would be unknown until ground conditions were assessed in detail.

I am also advised that there have been no assessments or analyses undertaken by Waterways Ireland in respect of the level of use or impact on the Spencer Dock Greenway.

I can inform the Deputy that the length of railway track disconnected from the rest of the loop line from the station when the bridge is in the ‘up’ position is approximately 16 metres. However, as the control and operation of the railway line in the vicinity of the lifting bridge lies entirely with Irish Rail, only it can indicate the extent of the permanent rail line that needs to be closed when the bridge is opened.

He might also have pointed out that €5m is more than WI’s entire capital budget, which is under €4m for all southern waterways for 2014. And if he were an argumentative chap, he might have pointed out that there is no evidence of a demand for

… the effective re-opening of the sea level of the Royal Canal to meaningful levels of year-round traffic …

and no evidence that it would be of any economic benefit to anyone, least of all the residents of Dublin Central, even if boats were travelling that way every day of the week.

He might, if he were an impatient sort of chap, have pointed to the idiocy of the “cultural heritage” argument: with one or two minor exceptions, pleasure craft were not part of the “cultural heritage” of the Royal but, even if they were, such “heritage” wouldn’t be worth millions that might be spent instead on bringing soup to the deserving poor of Dublin Central.

Ms O’Sullivan was back with more on 7 November, this time trying to get Leo Varadkar [FG, Dublin West] to get the National Transport Authority to include Effin Bridge and the Sheriff Street non-lifting bridge (not a Scherzer) included in a National Transport Authority study of “the management and movement of people and goods to, from and within Dublin city centre”. Ms O’Sullivan’s rather confused and confusing case seemed to be that there was a greenway, and there were walking and cycling routes along the canal, so a road bridge (that works perfectly well for carrying a road) and a railway bridge (that works perfectly well for carrying a railway) should be included  in the study because the canal has navigational potential.

Or something. She even managed to bring water polo [does she mean canoe polo?] into the argument.

As far as I can see, walking, cycling, road travel and rail travel — and even water polo — are not in any way adversely affected by the current arrangements, while the canal is of negligible importance in the movement of people and goods. Boating on the canal is a leisure activity for a small number of people who are sufficiently well heeled to own pleasure-boats; I am rather surprised to find that their interests are a matter of such concern.

As the expenditure on reopening the Royal Canal is a sunk cost, I am all in favour of making its use easier — provided that it can be demonstrated that (a) there is a demand for increased use, (b) such increased use will have benefits that outweigh the costs of any improvements and (c) no alternative investment offers better returns. As far as I can see, Ms O’Sullivan has demonstrated none of the three: indeed I see no evidence that she has even considered them.

What’s depressing here is the absence of any indication of a rational approach to capital spending on waterways. They’re still cargo: a magical source of wealth, that will bring peace and prosperity as long as we all believe in fairies and avoid facts, thinking and analysis.

No wonder the country is in a state of chassis.

Update 15 November 2013: some information about demand for passage under Effin Bridge.

No queue for the quay …

… at Querrin on the Shannon Estuary. The page discusses its building and the early years of its operation.

Horses on board

An ad from the Freeman’s Journal of 11 September 1876 provides a snippet of information about horse haulage on the Royal Canal, with a point that I cannot recall seeing anywhere else about Irish waterways. Here’s a French example and here’s an American from this excellent page.

Fun for anoraks

Lots of info on the WI website:

I liked the bit on this page:

Enforcement

Boats in non-compliance with the bye-laws will enter an enforcement process. Enforcement is undertaken by Authorised Officers and will begin with a notification in the form of a sticker and if non-compliance continues may result in the ​craft being removed from the navigation at the owners cost.

I wonder about investing in a crane company.

 

Like the Mary Ellen Carter …

rise againJust a few weeks ago the depth was around 1.7m at Athlone weir, about 7″ above the navigational minimum. But today the depth is over 2.4m and, with staff gauge zero at 35.360m above Poolbeg datum, the water level is 37.760 m above Poolbeg datum.

DUKWs

In June 2013 I reported on the sinking of a DUKW in Liverpool, the second of the year, and in September on the fire aboard a DUKW in London. Oddly enough, it seems that the two accidents had a common element: the foam added inside the hulls to improve buoyancy.

The UK’s Marine Accident Investigation Branch has found that the DUKWs in the Liverpool fleet had not been fitted with enough foam to provide 110% buoyancy, enough to keep the vessel afloat when flooded. MAIB’s tests on the Liverpool vessels

… raised serious questions about whether the operators of DUKWs could fit sufficient foam internally to comply with the current requirement for 110% buoyancy without compromising the safe operation and the practical day to day maintenance of these vehicles.

The “safe operation” part affected the London vessels. In July 2013, a DUKW had to be towed in after a drive shaft universal coupling failed when it overheated and ran dry of lubrication: engine bay temperatures were too high because of the volume of foam inserted. And a report commissioned by the London Fire Brigade into the September fire concluded that:

… the most likely cause of fire was the action of the rotating drive shaft (or other moving parts) on the oil contaminated surfaces of the buoyancy foam blocks.

MAIB has issued a safety bulletin [four-page PDF] with this conclusion:

The MAIB identified significant difficulties in fitting a DUKW with the volume of foam required to meet the buoyancy standards set out in MSN 1699 (M). Further, the nature of these old amphibious vessels, specifically their weight in relation to their size and the complexity of their propulsion arrangements, makes it difficult for operators to comply with the standards applicable to more conventional craft by solely using internal foam buoyancy. An alternative standard, ensuring that DUKWs have the necessary level of damage survivability, therefore needs to be established if they are to be operated safely.

It has recommended that the Maritime and Coastguard Agency should

… ensure that the means used by DUKW operators to achieve the required standard of buoyancy and stability for their vessels does not adversely impact on their safe operation. Furthermore, these vessels should not be permitted to operate until satisfactory levels of safety can be assured under all feasible operating conditions.

The Maritime and Coastguard Agency’s website doesn’t seem to be working, but there is a BBC report here quoting an MCA person as saying

We will not be permitting the vessels to operate until we are satisfied that the necessary safety measures have been achieved.

All of this may help to explain why the VikingSplash DUKWs operating in Dublin are fitted with additional external buoyancy.

Ardnacrusha

A press release just in from Waterways Ireland:

Waterways Ireland Change Advice on Travel into Limerick

Waterways Ireland is changing the advice on travel from Ardnascrusha into the Limerick Navigation due to a new service available from the ESB which provides real time information on the output from the turbines.

Boaters are advised not to travel on the Ardnacrusha to Limerick Navigation if the output from Ardnacrusha is above 20 Megawatts. The previous advice advised boaters not to travel if one turbine was operating; 1 turbine is equivalent to 20 megawatts.

The new service offers real time information on the megawatt output of Ardnacrusha by phone (tel 087-6477229) and is available 24hrs a day. Boaters are advised to contact the ESB phoneline for information on the output when making travel plans. In the event of a line failure in the real time information number, boaters can call the main Ardnacrusha number 087-9970131 for the megawatt information as well as any other information required for travel through Ardnacrusha.

This new information service is an improvement in safety for mariners who travel on the Ardnacrusha to Limerick Navigation.

Update 2018: that was in 2013. Much better information is now available here.
