Lattice Energy files plan for Otway Basin survey work (Australia)

first_imgBeach Energy subsidiary Lattice Energy is planning to carry out geophysical and geotechnical seabed assessments on its Otway Basin acreage off Australia.Survey map / Image by NOPSEMALattice has proposed to carry out the seabed assessments within eight titles in the Otway Basin in Commonwealth waters.The seabed assessment is needed to inform the future drilling of offshore subsea gas wells and potential tie-ins to connect the new gas development wells to the existing Thylacine platform and associated pipeline.At its closest point, the seabed assessment area is approximately 25 km from the township of Port Campbell, Victoria.The proposed seabed assessments will be carried out over two phases, the first starting in September 2019 and the second startin around March 2020. The seabed assessments are estimated to take between five to 12 days for each proposed drilling area and up to seven days for each of the tie-in flowline and umbilical corridors.Geophysical methods proposed include multibeam echosounder (MBES), Side-scan sonar (SSS), Sub-bottom profiler (SBP), Magnetometer.Geotechnical sampling includes piston coring or vibracoring, In situ Cone Penetrometer Testing (CPT), Seabed grab sampling.Seabed imagery at the well locations and along the flowline and umbilical corridors will be undertaken using a camera placed overboard via a tether and/or by a remotely operated underwater vehicle.The environment plan is now under assessment by the Australian offshore oil and gas safety regulator NOPSEMA.Spotted a typo?

Millions of bushels of grain in storage damaged or destroyed in Monday’s storm

first_imgState Ag Secretary Mike Naig says some of the corn that was flattened by Monday’s storm will bounce back, but it’s anybody’s guess as to what percentage of damaged Iowa crops may be harvested. Grain bins, silos and elevators were damaged as well, so losses extend to the 2019 crop.“Tens of millions of bushels of commercial grain storage and millions of on-farm grain storage was impacted, destroyed or severely damaged,” he says. Naig warns there will be storage issues for the 2020 crop, so farmers may have to truck their corn and soybeans further or resort to on-the-ground outdoor storage.“Certainly there’ll be a lot of effort to repair whatever storage can be repaired and brought back online before fall,” Naig says, “but it’s hard to imagine that any significant amount of the storage that’s been damaged will be able to be rebuilt before harvest this year.” The state climatologist says Monday’s derecho passed through about a third of the state. Naig says localized crop losses in central and east central Iowa fields that were flattened by Monday’s storm will be severe, but it’s too soon to estimate the value of crop losses in those high damage areas. Naig says some livestock barns were damaged, too, but there have not yet been reports that hogs, cattle or poultry were killed in the storm.last_img read more

R3bn in manufacturing incentives approved

first_img15 November 2013 The Department of Trade and Industry has approved more than R3-billion in incentives for 436 manufacturing enterprises since the inception of its Manufacturing Competitiveness Enhancement Programme (MCEP) in May 2012, says Trade and Industry Minister Rob Davies. The programme offers a number of incentives designed to drive growth in South Africa’s manufacturing sector by helping businesses meet challenges relating to poor market demand, high input (including electricity and transport) costs, cheap imports, and economic uncertainty. It also includes a package of incentives to help established manufacturers increase their competitiveness while retaining jobs. Briefing journalists in Johannesburg on Thursday, Davies said the 436 enterprises had a combined investment value of R13.1-billion, and would help to sustain more than 116 000 jobs in manufacturing. Davies said a key component of the programme was the Green Technology and Resource Efficiency Improvement incentive, which supports green technology upgrades and business development activities that lead to cleaner production and resource efficiency. “Out of the 436 entities that have been approved since the launch of the MCEP, 26 entities for a total grant of about R274.7-million are green manufacturing related,” Davies said. “Large export-oriented companies that have been at the forefront of investment in green manufacturing have projected an investment to the value of R727.4-billion and that 43 784 jobs will be sustained as a result of these investments.” SAinfo reporterlast_img read more

Hydroponic crop production workshop

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Growing plants in a liquid nutrient solution without soil in controlled environments, i.e. hydroponics, has been successfully used for greenhouse production of lettuce, tomatoes, herbs, and other crops. Hydroponic production is an agricultural production practice that optimizes energy consumption and water use; effectively employs chemical-free integrated pest management controls (IPM); permits agricultural production independent of season; and can generate higher crop yields with improved quality, consistency, and predictability, while exploiting less land. Hydroponics provides year round continuous production and crop yields that exceed field production by as much as 10-fold, all while optimizing resources including water, energy, space, capital, and labor. Hydroponics is an important agriculture practice commonly represented in greenhouse food crop production. However, hydroponic systems have a higher initial investment than soil-based crop production and require technical skills and careful management. Learn more from the expertsOn Feb. 8 and 9, 2018 greenhouse growers will have the opportunity to learn about best practices for growing crops in hydroponic systems. The Ohio State University Greenhouse Management Workshop, which is held annually, provides opportunities to learn from the experts in industry and academia. Below is a small sample of topics that will be addressed.The fundamentals of hydroponics production, including controlling the greenhouse environment and lighting needs, will be discussed by Chieri Kubota with Ohio State University (OSU). Peter Ling, OSU, will cover the importance of managing humidity and how to ensure it is optimal. Controlling plant diseases and using Integrated Pest Management practices will be presented by Sally Miller and Luis Canas, respectively, both with OSU.Glen and Lois Smuckers, hydroponic growers near Orrville will share their experiences, from why they chose hydroponics to how their system works. Chieri Kubota, OSU, will provide specific management recommendations for growing lettuce and tomatoes hydroponically, and Mark Kroggel, OSU, will do the same for strawberries. Other topics will address food safety, business plans, and more.The workshop will also feature a tour of the OARDC research greenhouses on day 1 and a tour of a commercial greenhouse using hydroponics on day two.For program and registration details, visit our website: http://fabe.osu.edu/greenhouse. Dr. Peter Ling and Mary H.

The Fundamentals of Rigid Duct Design

first_imgRELATED ARTICLESAll About Furnaces and Duct SystemsSaving Energy With Manual J and Manual DThe Two Main Reasons Your Ducts Don’t Move Enough AirKeeping Ducts IndoorsReturn-Air ProblemsSealing DuctsDuct Leakage Testing Once you know the BTU/h and cfm numbers for the building, you need to select the right equipment. ACCA’s Manual S protocol helps you do that. There’s more to it than just finding a piece of equipment that meets the total heating and cooling loads for the home. You’ve got to make sure you adjust for the indoor and outdoor design conditions of the home. Ideally, you have the manufacturer’s performance data tables to help you get it right.Then you’re ready to start designing the duct system.Getting the right air flowIf you take a fan out into your yard on a calm day and turn it on, you’ll get its maximum air flow. If you take that same fan and blow the air into a cardboard tube, it has to work against the pressure that builds up in that space. The more you reduce the size of that tube or make it longer or turn the air with it, the more static pressure builds up. And the more the air flow is reduced.That’s the basic principle you have to work with in duct design. I’ve written previously about the two factors involved in reducing air flow in ducts. One is friction. As the air moves through a duct, it interacts with the surfaces. The smoother that inner surface is, the more air flow you get. The rougher the surface, the less air flow.The second factor is turbulence. This generally arises when you move air through fittings or when you turn the air. With rigid duct, you turn the air with fittings, but unfortunately that’s not always the case with flex duct.When air comes out of the air handler, several things happen to it. It gets sent to the various rooms in the house. As it travels through a trunk-and-branch duct system, the quantity keeps diminishing because some of it gets diverted down each branch on the way to the end.Each section of duct, each fitting, each turn of the air, adds resistance to that air flow because of friction and turbulence. Grilles and registers, filters, and balancing dampers also add resistance. That resistance results in decreases in the static pressure, or pressure drops.The duct design processIn designing a duct system, you’ve got to know how much static pressure you have to work with and how much you lose because of the factors I listed above. Air handlers are rated for a certain total external static pressure. A lot of times that number is 0.5 inches of water column (iwc). Then you subtract from that the pressure drops of the components that aren’t ducts or fittings. That gives you the available static pressure. That’s how much you have left to “spend” on your duct system. If you overspend with a restrictive duct system, the static pressure goes up and the air flow goes down. Don’t do that.Friction and turbulence both result in static pressure drops and reduce air flow. The way we quantify this in the duct design process is with total equivalent length. For straight sections of duct, we just use the measured length. For fittings, though, we need to find the equivalent length (explained below) for each one. (They’re in ACCA’s Manual D and the ASHRAE Handbooks.) Once we have those numbers, we add up all the lengths and equivalent lengths of the longest run to find the total equivalent length.The next step is to divide the available static pressure by the total equivalent length. That results in what’s called the friction rate, which we need to determine the size of the duct. You can use a duct calculator or software to go from friction rate to duct size.So what exactly is the equivalent length? It’s how long of a straight section of duct you’d need to get the same pressure drop as the fitting. The table of rigid elbows in Image #2 below (from ACCA Manual D) shows equivalent lengths for various shapes and designs of these fittings. Looking through the table, you can see that there’s quite a range. You could use an elbow with and equivalent length as low as 10 feet or as high as 75 feet.In the duct design process, you’ve got to account for the standard pressure drops in the filter, registers, and grilles. Then you add up the equivalent length of the longest runs in your supply and return ducts. The goal is not to use more pressure than you have available. Pretty simple, right? Not always.We do third-party HVAC design and we try to be a little conservative with the fittings we choose. For example, we might do our design with a 3-piece elbow that has an equivalent length of 35 feet. If the installer uses a more common 4-piece elbow, the equivalent length is less, so it should result in better air flow than we designed for. Then if they spend that little air flow dividend somewhere else, we’re covered.When designing a duct system, you have to account for all these things. With rigid duct, you can get more predictable results if you use the fittings called for in the design. With flex, it can be significantly worse than you expect because of what installers do to that stuff. Not that it can’t be done right. I’m fine with flex duct myself, as long it’s used only for straight runs and pulled tight.Two ways that hard pipe can be worse than flex ductHard pipe has less friction than flex duct. You can’t (easily) squeeze it between a drain line and a floor joist. And contractors who use it actually install fittings to turn the air. But in two respects, flex duct has the advantage:Hard pipe doesn’t come pre-insulatedHard pipe can be leakier than flex — much leakier.Those flaws are far from fatal, but they do require careful attention during installation. I’ve tested older rigid duct systems that had really high leakage. The one shown in Image #3 (below) seemed to be held together mainly by the rather thin insulation. When I took the insulation off, this branch duct just fell apart.A few takeaways for good duct designLet me wrap this up with a few guidelines for good duct design.Go for predictability. A straight run of hard pipe is more predictable than a straight run of flex. A straight run of flex pulled tight is more predictable than the typical flex installation. Turning air with fittings is more predictable than turning air with flex.Know your limits. The blower you choose limits the static pressure you have to work with. The components you add and the duct system you design must work with that limit. If you overspend on a restrictive duct system, you won’t get the amount of air flow you need.A good duct system needs more space than you might imagine. Especially near the air handler, ducts generally need to be bigger and have longer runs than they’re usually designed for.Place the air handler in the center of the house if possible. Running trunk lines away from the air handler in two directions makes it easier to get good air flow because of fewer downstream branches than a single trunkline.Design to minimize equivalent length but build in some cushion. Make sure your design will work even if the installers make a few substitutions or mistakes.There’s a whole lot more to this subject than I’ve discussed here. And that’s why there’s a whole book on this topic. It’s called Manual D. Allison Bailes of Decatur, Georgia, is a speaker, writer, building science consultant, and the author of the Energy Vanguard Blog. You can follow him on Twitter at @EnergyVanguard. At the end of this month, I’m giving a little presentation at the ASHRAE conference in Las Vegas. Actually, I’m doing one third of the whole presentation, which is titled Flex Ducts, Hard Ducts and No Ducts: Migration Patterns for Duct Hunters (or not) in the Land of Thermal Comfort. My part is on hard ducts.Chris VanRite is doing flex duct, and Robert Bean will cover the no-ducts part (which doesn’t refer to ductless minisplits but rather to hydronic distribution). We get 15 minutes each, so I’ll elaborate on my part a bit here.Before duct designDesigning a duct system is important, but there are a few critical steps that come first. Number one is the load calculation using a protocol like ACCA’s Manual J or the ASHRAE Handbook of Fundamentals. You’ve got to know how much heating and cooling you need for each room. Then those BTU/h requirements immediately translate to room-by-room air flow requirements in cubic feet per minute (cfm). It’s done automatically in the software we use (RightSuite Universal by WrightSoft).last_img read more

First Comes Play, The Rest Will Follow: A Four Part Webinar Series on Play

first_imgby Kristie Pretti-Frontczak, PhDImage by BethL at pixabay.com, Licensed Creative Commons Zero (CC0)“Play is often talked about as if it were a relief from serious learning. But for children play is serious learning. Play is really the work of childhood.” Fred RogersWhen Fred Rogers and many of his predecessors, such as Maria Montessori, spoke of play, they did so with an understanding of the great importance it serves in human growth and development. Play is more than “just having fun,” and it is more than the outcomes that are achieved. It is through play that children experience the world. It is through play that neural pathways are created and strengthened. Repeated opportunities to experience, explore, and interact with the world is necessary for developmental processes to unfold. In fact, researchers have provided “unequivocal evidence that the brain physically changes, increasing and strengthening the neural connections through repetitive experience” [2]. That means, through multiple opportunities to play, children are able to watch, copy, practice, and eventually learn….EVERYTHING.In this webinar series, we will not only explore the importance of play, but we will deepen our commitment to fostering strong relationships with children and learn strategies to expand the richness and complexity of their play. Together, we’ll learn how children go from sensory exploration to developing highly complex and cooperative play skills. Together, we’ll learn how “[r]ather than detracting from academic learning, play appears to support the abilities that underlie such learning and thus to promote school success.” [1]More specifically, in 1-2-3 Play with Me! Recognizing and Valuing the Power of Play, we will examine how children are naturally curious and learn best through practice and observation. A highlight from this webinar will be to gain strategies for being a strong play partner. In Have a Seat! Learning What Children Know Through Play, we will consider the advantages of assessing during play. A highlight from this webinar will be to learn strategies for engaging in authentic assessment practices as we aim to better understand what children know and can do. In When Play is More than Just ‘Playing‘: Delivering Intentional Instruction through Daily Interactions, we will focus on the importance of teaching the whole child and promoting emotional, social, motor, and cognitive skills through play. In this webinar participants will be to learn how to build upon children’s natural curiosity and embed instruction in a way that continues and extends vs. disrupts learning. Lastly, in Beyond the Shape Sorter: Playful Interactions that Promote Strong Academic and Social-Emotional Skills, we will examine the relationship between play and a child’s future success. A highlight from this webinar will be to explore how to support all children through play, even those who may be “stuck” and don’t seem to find new and more sophisticated ways to play.Please join us for this four- part webinar series, as we explore how play is foundational to individual and collective growth in children ages birth to five.References[1] National Association for the Education of Young Children [NAEYC].
