About the event: Timber is gaining increasing recognition as a sustainable structural material. However, unlike steel and concrete, timber is a natural material, and therefore does not have consistent structural properties. This lecture will take a look at the characteristics of timber and the challenges the material poses in relation to structural design, and will present an overview of the practicalities of this type of construction, including design of elements, sourcing timber, dealing with the Irish building regulations, jointing techniques, durability, thermal mass, advantages and disadvantages, etc. Reference will be made to various building projects ranging from houses to churches, and also to some recent research work relevant to practice.

Spirit of Ireland Lecture

This presentation will proceed as planned, however we are unable to webcast it and we hope to reorganise a webcast for another time.

INNOVATION OR FANTASY – PUBLIC LECTURE TO EXPLORE POTENTIAL OF WIND ENERGY

A public lecture on the very topical subject of our energy resources will be held In the Sligo Park Hotel on Monday 19th October (8.00pm start). The lecture is being hosted by Engineers Ireland and will focus on the ‘Spirit of Ireland’, the National Project for Energy Independence.

Graham O’Donnell of the ‘Spirit of Ireland’ Project Team outlined the background to the project. ‘The Spirit of Ireland initiative was launched last May, and has received a lot of favourable publicity. In essence, this ambitious proposal involves storing wind energy in pumped seawater reservoirs along the western Irish coast. Wind is an intermittent resource which varies with the seasons and with weather conditions. Electricity demand also varies enormously over a given 24 hour period. While there is an abundant wind energy resource in Ireland, output cannot be controlled to meet varying energy demand as is typical with conventional power stations. Therefore to utilise surplus wind energy when it is available, the energy produced needs to be stored.’

Innovative

The Spirit of Ireland project proposes to construct water storage reservoirs at natural high points along the coast. Wind energy would be used to pump seawater from sea level to the upper reservoirs. This water is then released through turbines which generate electricity when needed. This solves the problem of matching supply with demand such as using up surplus wind energy at night when demand is low.

While this proposal is innovative, there are significant challenges also including agricultural, environmental and social impacts.

Ireland already has one such pumped storage facility at Turlough Hill in Co Wicklow. Built in the late 1960’s the upper reservoir contains over 2 million cubic metres of water which is controlled to provide a balance between day and night time electricity demands.

Energy Costs

Michael Carty, Chairman of Engineers Ireland Northwest Region, anticipates a very high level of interest in the lecture. ‘In economic terms, Ireland’s future is bound up with the cost, security and stable supply of energy. At present we are highly dependent on imported fossil fuels and are therefore exposed to volatile international prices for oil and gas. In addition to having a direct influence on our cost competitiveness, our reliance on imported fossil fuels raises the carbon intensity of our economy and works against imminent Kyoto targets.’

The Spirit of Ireland project as proposed, is so vast in scale i.e. provide all of Ireland’s energy requirements within 5 years, that it will directly impact on Irelands economy, security of energy supply and carbon targets. This initiative to harness a natural resource has generated both support and scepticism but nonetheless kick-started a national debate on large scale investment in renewable energy.

Join Engineers Ireland northwest on Monday 19 October in Sligo Park Hotel at 8:00pm to learn more. Graham O'Donnell, Electrical & Electronics Engineer, is one of the leaders of this project, has over 20 years experience of international power networks and will present the lecture.

From Piled Embankments to off Shore Anchoring Systems

2008-11-20T01:15:00.000-08:00

From Piled Embankments to off Shore Anchoring Systems – Geotechnical Research
at the Institute of Technology Sligo
Presented by
Dr Pat Naughton & Dr Con O’Loughlin
School of Engineering
IT Sligo
Monday 24th November, 2008, 8pm (Room A0004 - IT Sligo)

The Institute of Technology sector has expanded rapidly in recent years. In IT Sligo educational programmes in Civil Engineering range from Ordinary and Honours Bachelors (accredited by Engineers Ireland) to Masters and PhD degrees. The Geotechnical Research Group, lead by Dr Pat Naughton & Dr Con O’Loughlin has being awarded over € 650,000 in competitive research funding in the last year. The group currently has five Masters and PhD students researching piled embankments, site investigation techniques, reuse of marginal poor quality fills and off shore anchoring systems. In addition, internal funding from the Institute has allowed the
group to develop a state of the art geotechnical laboratory and facilitated the purchase of the first geotechnical centrifuge in Ireland. The centrifuge will greatly enhance the groups testing and research capabilities.

This presentation focuses on two particular areas of research currently conducted by the group: piled embankments and off shore anchoring systems. Piled embankments are used around the world to control settlements of road and rail infrastructure constructed on soft compressible soils. Off shore anchoring systems are used extensively in the construction of off shore energy farms and in the oil industry. An overview of the research mythologies and current findings are presented, along with the implications for design and construction in these applications.

The IT Sligo geotechnical centrifuge will allow study of the behaviour of foundations, offshore anchorages, embankments or supports, using reduced-scale models. The scale-reduction factor of the model is equal to the centrifugal acceleration being applied, typically up to 100g. Load cells, displacement transducers and photographic techniques allow loads and deformations in the model to be quantified. Details on how this advanced testing technique will be integrated into the investigation of these two research areas are presented.

A recording of the two presentations is available here (there are some sound problems in the second presentation)

Webcast Recordings are available, but there were a few technical problems with connectivity. The recording was split into two parts. The sound was too low for the first 3 minutes and it took another minute to get it sorted. In addition we lost connectivity after about 24 minutes and it took us a few minutes to get setup again. The last 39 minutes is in a second recording where the sound seem to have been fine but there is a little problem of synchronisation with the slides from time to time. However we hope you find it useful:

Abstract:

The lack of national policy to deliver modern communications has resulted in the absence of a carrier independent core infrastructure and a strategically planned last mile delivery. Universal service in Ireland was defined for voice, not for data. This has been addressed in other jurisdictions by building codes rather than technology. The only feasible short and medium term solution to the deficit of last-mile infrastructure is the planned and structured use of wireless technologies. Although a number of discrete government owned fibre and microwave networks exists, government funded networks have generally been single purpose and do not integrate or collaborate at a business level.

Rural towns of population sizes greater than 1,000 generally have competitive broadband services based on DSL and wireless, however coverage issues are common. There is generally considered to be no commercial case for broadband services in dispersed rural areas.

To provide for home-working business applications 1mbs of TCPIP with low latency has proved sufficient. Recreational use tends to have a greater requirement. Business sites will clearly require much greater capacity.

Present 3G/UMTS technology is unlikely to deliver to end-users expectations in the medium term. A typical HSDPA site will provide up to 7.2mbs/sector downstream (theoretical 14mbs). However there is no way to predict the simultaneous customer numbers and quality of service.

Empirically, using unlicensed 5.8ghz WiMAX equipment total throughput of 54mbs/sector is currently achieved and there is an expectation of doubling this within 6 months. The same technology can be used for point-to-point links, currently delivering dedicated 54mbs to a typical business customer. Using licensed 3.5 ghz WiMAX throughputs are considerably lower due to the available spectrum. A carrier grade core will typically include diverse licensed microwave links and MPLS switches.

The economics indicate a Wireless ISP (WISP) using unlicensed technology with a single site could break even over a period of less than two years. However, the construction of a carrier grade core is capital intensive and requires more complex business modelling. Licensed technology is considerably less economical.

The constraint on the use of wireless is the availability of spectrum. A typical 5.8ghz site will use discrete 20mhz channels, giving a maximum of 360 end points per site. Throughput from licensed technologies will be lower due to the smaller channel sizes, guard bands and exclusion zones. The same issues exist for UMTS. Ongoing roll-out of wireless technologies will require higher density of sites
