Sarens goes for Straightpoint

first_imgFour identical load cells, each with a capacity of 149 tonnes, were used to measure the 287 ft (87.4 m) distillation column, which weighed in at around 640 tonnes.Each end of the distillation column was weighed by lifting it with a self-propelled modular transporter (SPMT) and positioning the load cells between the SPMT deck and the unit’s support beams. The readings from each end were combined to determine the total weight.”The distance from support beam to support beam, along with the weights of each end were utilised to determine the location of the center of gravity. This data was used to verify the loading to each of the two cranes that were used to upend the vessel from horizontal to vertical,” said Sarens project manager Jay Holt.Straightpoint general manager John Molidor explained that this is a common method of measuring loads of this kind, and it is growing in popularity.”We have participated in more such lifts already this year than last and I expect that trend to continue. The cable free wireless system is user friendly and virtually maintenance free.”   www.sarens.comwww.straightpoint.comlast_img read more

Iris 320 casts an expert eye over the French network

first_imgSNCF has completed a €33·5m programme to convert a TGV Réseau trainset for inspecting track, overhead electrification, signalling and telecommunications systems at speeds up to 320 km/h. Laurent Charlier reports,SNCF’S INFRASTRUCTURE division now has a new inspection tool at its disposal, which promises a real ‘leap in performance’ as then SNCF President Louis Gallois enthused during the unveiling of Iris 320 on June 12.Originally conceived as MGV (Mesures à Grande Vitesse), Iris 320 brings together in a single, self-propelled train capable of operating at up to 320 km/h, or even 350 km/h under certain conditions, the complete range of infrastructure inspection and recording functions. These were previously undertaken by a whole fleet of specialised vehicles with different, and much lower, operating speeds.SNCF manages the maintenance of the French national rail network on behalf of RFF. Iris 320 will simplify infrastructure inspection on the high speed lines and part of the conventional network, some 7500 track-km in total. Because it performs a wide range of functions at the maximum line speed, the new train will also free up train paths for commercial services. Another benefit is that inspection of the high speed lines no longer has to be undertaken within maintenance possessions. More frequent and more rigorous inspection of track, electrification equipment, signalling and telecommunications should also help to improve the efficiency of maintenance operations, and encourage a general move from a reactive to a preventative maintenance regime.Higher operating speeds and the ability to undertake in one pass operations previously divided between a number of vehicles enable more frequent inspections to made, which through data analysis should enable defects to be more readily prevented. Iris 320 will inspect between 3 500 km and 5 000 km every week, or 200 000 km every year. One week every three months has been reserved for maintenance of the train and its onboard systems. The train is staffed by two drivers and seven inspection technicians, and is equipped with a kitchen, dining area, sleeping accommodation and showers.Holistic infrastructure managementSystematic inspection of the rail infrastructure using this new tool should enable SNCF to build up a complete picture of the state of the French rail network. Detailed local information on the condition of track, electrification equipment, signalling and telecommunications systems will now be available to the respective maintenance teams. Project Manager Jean-Marie Descusses stresses SNCF’s desire to ‘exploit the synergies between the different parameters measured to improve data analysis and the understanding of physical phenomena’.The total number of parameters measured in a day by Iris 320 represents between 60 Gb to 100 Gb of data. The results are presented in real time and assessed on board, enabling data to be accepted or rejected depending on the quality and usefulness. This means that the results can be made available without the need for extensive analysis or processing off the train, and they can easily be compared with the results of previous inspection runs.Classified as normal, urgent or critical, the inspection data is also transmitted by GPRS (with a slight time delay) for storage on a national server with a capacity of 80 Tb and an archiving capability of 20 years. On board Iris 320, the IT hardware comprises six redundant servers linked to measurement sensors and 12 workstations via a local area network with 20 km of optic fibre cabling, capable of transmitting data at a rate of 4 Mb/sec.Maintenance teams should now be able to call up data captured by Iris 320 wherever they require it. Data is presented in the same format as used previously, but changes are likely to be made over time accompanied by appropriate training.In-house solutionSNCF says that designing and building Iris 320 in-house has ensured that the performance of the new inspection train has been closely matched to the requirements of its infrastructure division. In addition, making good use of its own expertise has helped keep costs under tighter control; the railway reckons that recourse to an external supplier would have cost five times as much as the €33·5m spent on the project.Of this total, €21·2m was needed to purchase a TGV Duplex trainset to replace the TGV Réseau set which was converted into Iris 320. No 4530 was the last three-voltage (25 kV 50Hz AC, 1·5 kV and 3 kV DC) Réseau set to be built, and was converted for its present role by SNCF’s Hellemmes workshops in Lille, under the direction of the rolling stock division and its engineering centre at Le Mans. On December 9 2005 the train was delivered to Le Landy depot in Paris for final modifications and installation of the monitoring equipment.Although it is a world-class inspection tool, and SNCF is keen export its expertise in this field, Iris 320 is unlikely to be seen much beyond the frontiers of its home country. ‘The French inspection programme is already very full and will become even more so with the opening of new lines such as TGV Est and TGV Rhin-Rhône’ said Descusses. In theory Iris 320 is currently capable of operating in Spain and as far as London, although its pantographs are not configured for the Channel Tunnel. In practice it is only expected to cross the French border to reach Brussels.

He added that “it is a good date” and he does not think that it will affect Christmas.“It’s time for elections, people want the election date called, they want it and we are going to the polls,” he said.Another female supporter of the DLP said, “I am very, very happy. They got it, they were calling for it all the time so now they get it, let’s go. That’s a sure win”.A third supporter, also female, who could not contain her excitement said, “I am so excited, I am supercalifragilisticexpialidocious”.“I am so excited because if you put Roosevelt Skerrit with three past governments, Roosevelt Skerrit has done the most. We cannot leave all those capital projects to these guys,” she said.Amidst the excitement, there were some citizens who were not as jubilant.One citizen noted that “the United Workers Party has been asking for new elections and they have gotten it so let’s wait and see who’s going to be the new government”.Meanwhile, one citizen said “Skerrit trembling, he afraid of Lennox”. He however admitted that it is a good date. “It’s a good date but all I know is Skerrit afraid”. Additionally, there was some concern expressed about the election date and that it might affect the Christmas Holiday.“I think they should have put it to a later date, not in December. You know December is a time when everybody is going to plan for their family, now you going to have division because who are Labourites, who are Workers and there is going to be a lot of division, that’s what I believe,” she said. – / 18Dominica Vibes Newslast_img read more

first_img Share EducationLocalNewsPrimarySecondary Principals encouraged to embrace change in new school year by: Dominica Vibes News – September 13, 2017 Share 58 Views   no discussions Tweetcenter_img Sharing is caring! Share Minister of Education and Human Resource Development, Peter Saint JeanPrincipals around the island have been encouraged to use the ever-changing technology and opportunities available to lead their schools to success. This was announced by Minister responsible for Education and Human Resource Development, Peter Saint Jean, who was dressing the annual Principals’ Meeting held on Friday, September 8th, 2017. Saint Jean told the principal’s that as leaders of their schools, they are expected to be motivational to their team as they face change. “Keep in mind, principals, that as a leader one of your key roles is that of a facilitator. It is important therefore to motivate your team both professional and ancillary as partners in achieving the common goal of quality teaching and learning. To be an effective leader, you must consider being an agent of change, and change most times does not come easy,” he stated. Saint Jean noted that in an age of technology, as educators they must be willing to move on from outdated practices to ensure that their students are given the best chances at learning. “No longer can we depend on the outdated ways that we used before. It is okay to adapt to the changing needs of your students, you must be willing to take your school into new frontiers of teaching and learning” Saint Jean added. He told principals they can take their school to the next level by using the computers and other technology made available to them and encouraged them to move away from the normal classroom teaching methods while getting innovative with their lessons. He also urged the principals and teachers to grab unto the opportunities made available to them such as training workshops and seminars, which will aid them in their professional development. “Taking your schools to new levels of teaching and learning will, in this new academic year, also mean giving support to government’s stated objective to improving offerings to students with special education needs,” Saint Jean further stated.last_img read more

Steve Smith gearing up for hostile return

first_imgCricket On a drizzly, windy, thoroughly uninviting afternoon at Edgbaston, Steve Smith ramped up his preparations for the first test with barely anyone around. It will be a very different story tomorrow when the Ashes begin at the heaving ground in an affluent, leafy area just to the south of the centre of the West Midlands city. Justin Langer and the Australian camp are certainly not kidding themselves that Cape Town trio Smith, David Warner and Cameron Bancroft will be welcomed back to the test arena with open arms by England’s most football-like crowd. There wouldn’t be a warm embrace even in normal circumstances. They know Langer’s pre-World Cup plea for Smith and Warner not to be booed, which was emphatically ignored, is sure to fall on deaf ears again. It is a reception, as Smith faces up to bat during the first test, that will demand he rely on the singular focus which helped propel him to such lofty status as a test batsman before he was banned in March last year. The good news is that focus has gone nowhere. The former captain was the only specialist batsman to attend an optional session on the team’s second day in Birmingham before the Australia and England sides began full training on Monday. Optional is not a word that’s in Smith’s vocabulary when it comes to batting, as anyone who has watched him closely over the years will know. He practised in the outside nets along with a few of the bowlers and captain Tim Paine and when the rain began to fall too heavily, switched to Edgbaston’s indoor facility. He faced throwdowns from batting coach Graeme Hick, before having the Englishman feed balls into the bowling machine at him, and then another round of throwdowns. By then, a couple of hours had gone by and everyone else had left. Hick’s right arm had a relative breather for a year or so, but no more. “He just feels he needs to hit a lot of balls to get in the right head space and the right confidence,” said fast bowler Josh Hazlewood. “Ask his old man, he’s always been the same. His shoulder is still hanging by a thread, I think, from throwing all those balls. Nothing has changed over the years.” Australia are banking on Smith’s exhaustive attention to detail and work ethic resulting in a prolific series. With bowlers on both teams being tipped to dominate, the contributions of Smith and Warner loom as being crucial to the tourists’ bid for a first Ashes win in England since 2001. They are no longer captain and vice-captain but with 44 test hundreds between them their presence has instilled additional belief in Langer’s squad. “It’s just nice to have them back because they’re great blokes and world-class cricketers,” Usman Khawaja said. “They add that extra dimension to our team, they’re two of the best batsmen in the world. “It gives us all extra confidence, obviously having a strong batting line-up, having guys who have done a lot of good things in Test cricket, scored a lot of runs. It’s just good for the team in general.” – SMHlast_img read more
