Following the addition of advanced new units using Sea Water Reverse Osmosis (SWRO) technology at its Jebel Ali Power Plant and Desalination Complex, the Dubai Electricity and Water Authority (DEWA) has said its desalinated water production capacity has increased to 490 million imperial gallons per day (MIGD).

Saeed Mohammed Al Tayer, MD & CEO of DEWA noted that DEWA currently has 43 Multi-Stage Flash (MSF) water desalination units with a total production capacity of 427 MIGD of water at the D, E, G, K, L, and M Stations. It also has two SWRO plants with a production capacity of 63 MIGD. DEWA’s total production capacity of desalinated water is 490 MIGD at the Jebel Ali Power Plant and Desalination Complex.

“We work in line with the vision of the wise leadership to develop a world-class infrastructure to keep pace with the growing demand for energy and water and provide excellent services for over a million customers in Dubai according to the highest standards of availability, reliability, safety and efficiency. This is supported by assets worth more than $49.5bn owned by DEWA and its subsidiaries, as well as investments of up to $23.41bn over five years in the energy and water sectors,” said Al Tayer.

He noted that DEWA aims to increase its SWRO production capacity by 303 MIGD by 2030; reaching 42% instead of its current share of 13%. The desalinated water production capacity will reach 730 MIGD in 2030. SWRO desalination plants require less energy than MSF plants. One of DEWA’s latest projects, Jebel Ali K-Station, which has a production capacity of 40 MIGD uses this technology.

Nasser Lootah, EVP of Generation Division at DEWA said that the utility company adopts smart technologies that allow effective desalination plant control and monitoring, thus enhancing availability and reliability.

For the first time, DEWA implemented in ‘K’ station SWRO plant the Dissolved Air Flotation (DAF) system to treat water and remove any pollutants prior to desalination process. This enables the desalination process to continue in all conditions especially during red tide when total suspended solids and turbidity reach high levels, the statement explained.

Moreover, the two-pass reverse osmosis system implemented in this project guarantees a high quality of potable water. The SWRO plant is equipped with highly efficient recovery devices 96% efficiency, which utilise the high pressure from the first pass brine/reject stream and transfers it to a portion of the feed water stream to first pass inlet. This significantly reduces electricity consumption in the high pressure pump, thus enhancing efficiency of the desalination process, DEWA noted.

The utility company also stated that it ensures desalinated water quality through continuous monitoring across all stages of the desalination process, thus allowing customers to have access to drinking water that meets the highest international quality and safety standards including that of the World Health Organisation (WHO) for producing, transmitting, and distributing drinking water.

Developer Dar Al Arkan in collaboration with Danish robotic 3D construction printer company Construction of Buildings on Demand (Cobod), has introduced 3D construction printing (3DCP) technology in Saudi Arabia. The move is billed as a regional first and is expected to help accelerate construction work, while enhancing safety and reducing wastage and errors.

According to a statement from Dar Al Arkan, the technology is enabling it to spearhead the transition of the industry towards advanced and sustainable building practices, while complementing the goals of Saudi Vision 2030 to support economic diversification and digitisation.

Unlike traditional home-building methods, 3DCP cuts the construction time by more than half, is more flexible and requires less manpower, since it takes only three workers to build one house. This also contributes to decreased Lost Time Injury, creating a safer workplace. Additionally, less concrete is needed to complete a building, making the technology more sustainable and a viable solution for a low-carbon construction industry of the future, the statement explained.

For consumers, the combination of these advantages ensures lower costs and more affordability compared to traditional construction. As 3DCP increases the accuracy of construction, there will be less repairs and rework too, helping save long-term costs and adding to the value of the property, stated the developer.

“Our goal is to develop the Kingdom’s real estate sector by integrating the latest trends and technologies, drawn from global best practices to enhance our industry locally and deliver on the objectives of Vision 2030 at many levels. The introduction of 3D construction printing will revolutionise our approach to construction and enable us to focus on greater flexibility of design, strengthen productivity and achieve higher cost efficiency. This will raise the industry standards, achieve excellence and position the Kingdom as a leader in this sector, while making us highly competitive in 3DCP technology,” said Dar Al Arkan vice chairman Ziad El Chaar.

Dar Al Arkan said the technology was very important in insulation and reduces electricity bills. A combination of reduced waste of construction materials, less need for repair or rework and low on-site LTI incidents will enable highly cost-efficient project management than traditional construction, it stated.

The first 3D printed house would be ready by Q4 2021 and will be located in the Shams Ar Riyadh project, the developed pointed out.

Cobod founder & GM Henrik Lund-Nielsen added, “Saudi Arabia represents the largest potential market in the Middle East for our disruptive 3D construction technology and many large end customers in the Kingdom have been eagerly awaiting, that the technology became available via an established local company. Therefore, it has been very important for us to team up with the right Saudi partner for the deployment of our technology. We are very pleased with the fact, that such an important and influential company as Dar Al Arkan have chosen to partner with us.”

He concluded, “We look forward to working with them and to assist them with assuring the success of the 3DCP technology in the Kingdom.”

Topcon-paving_1000x600.jpg

June 21, 2021 valueeng0

Topcon Positioning Group has announced system solutions designed to support curb and gutter paving professionals by maintaining productivity and accuracy, even when facing difficult GPS coverage issues.

Using either the GT-1200 series robotic total station or the LN-150 robotic layout navigator, customers can augment their existing Millimeter GPS concrete paving solution and remedy issues such as foliage canopies, large buildings, tunnels, overpasses, and more.

“Although Millimeter GPS has become the gold standard for efficient, accurate, curb and gutter work, situations do arise in which that solution is simply not available,” said Brian Lingobardo, Topcon business manager, concrete paving. “In such cases, temporarily turning control of the paver over to a robotic instrument will still ensure that production is maintained.”

Both instruments offer support for a prism solution to quickly switch between Millimeter GPS and LPS (local positioning systems); both use Topcon LongLink communication for robust connectivity.

The self-leveling LN-150 is ideal as an easy-to-use, cost-effective robotic solution while the GT-1200 series instruments can serve that purpose and perform a full range of functions as a standalone surveying total station.

The new solution is particularly timely as many parts of the world continue to emerge from pandemic-related slowdowns. With workloads on an upswing, concrete professionals are facing increased pressure for productivity and accuracy, both of which can be ensured with the addition of robotics.

“With this additional offering, we are giving the curb contractor the tools they need to go up against any given situation,” added Lingobardo. “Millimeter GPS will still be the solution of choice for today’s curb and gutter pro; these options simply make a great system even better.”

Caterpillar has launched new hydraulic mini excavators built on the company’s Next Generation platform that introduce industry-first features for the 2.7-3.5t class machines, such as stick steer, cruise control, operator adjustable settings, and tilt-up canopy or cab as standard equipment.

A statement from the company said that the new Cat 302.7 CR, 303 CR and 303.5 CR hydraulic mini excavators boost operating efficiency, servicing ease and operator comfort. Expanded use of common parts throughout the Next Gen line plus the sturdy exterior design help reduce parts inventory investment and lower repair costs.

Daily maintenance checks are quickly made from ground level through side doors, while the tilt-up cab design offers easy access to components for servicing.

“Increased service intervals mean these excavators spend more time on the job and less time in the workshop. Combined, these features lower total ownership costs up to 5% compared to previous models,” said Cat’s statement.

Design enhancements for the new 302.7 CR, 303 CR and 303.5 CR deliver up to 10% more performance in travel and trenching. Hydraulic system upgrades improve lifting performance and cycle times, while customisable operator settings improve efficiency, Cat added.

The Cat C1.1 Turbo engine powers the 302.7 CR and 303 CR models, while the Cat C1.7 anchors the powertrain for the 303.5 CR. Both engines offer 17.6kW net power. Standard auto idle and auto engine shutdown help to conserve fuel usage at the site for more affordable operation.

According to Cat, these Next Generation hydraulic mini excavators feature a compact radius swing that reduces overhang when working to the side, allowing the machines to optimise performance in confined spaces.

Fixed undercarriage widths for the 302.7 CR, 303 CR and 303.5 CR of 1,500, 1550 and 1780mm respectively, deliver job-site accessibility and stability for lifting performance. An expandable undercarriage option for the 302.7 CR allows the operator to hydraulically retract track width to 1355mm for fitting into confined spaces and then expand width to 1780mm for superior digging and lifting stability.

Interchangeable counterweight packages enable customers to tailor machine weight to job requirements, offering the balance between low ground pressure and lifting performance.

The “light” counterweight option adds 100kg to machine weight, while the “extra” adds 250kg.

All three Next Gen models offer both standard- and long-stick configurations. Standard digging depths range from 2450-2810 mm, while the long stick configuration allows the machines to reach from 2650-3110mm depths.

The standard dozer blade further increases machine flexibility to handle backfilling and grading tasks. It features ample above- and below-grade travel and has a standard float function for easy clean-up. An angle blade option on the 303.5 CR gives further flexibility in backfilling applications for increased productivity.

June 20, 2021 valueeng0

Mammoet has launched two floating drydocks weighing 1450t each via the float-off method in Saudi Arabia, marking the first time this procedure was performed in the kingdom.

The 85m-long, 34m-wide and 11m-high drydocks, built at Zamil Shipyard in the port of Dammam, are intended for maintenance and repair works of Saudi naval crafts and are commissioned by Constructions Mécaniques de Normandie (CMN), a French naval ship design and construction company.

Mammoet said that its Saudi Arabia branch was contracted by CMN to launch the drydocks using the float-off operation. “Using its vast expertise in marine load-out and float-off operations, Mammoet undertook all engineering, procurement, logistics and execution for the successful float-off of the drydocks,” added the global heavy lifting and moving specialist.

Mammoet’s statement added that In the concept stage, the team proposed a solution for the float-off that has never been performed in the kingdom before. The solution entailed the use of a large floating dock with the capability to perform float-off directly at the jetty. The use of the proposed dock eliminated the traditional offshore float-off and related logistics. This gave the client a commercial advantage that in addition to the costs, saved a significant amount of time.

A thorough transport and marine engineering, multiple risk assessments and warranty surveys were performed to ensure safe and efficient execution. The floating dock, mooring and ballasting equipment were mobilized from UAE along with a specialized team to execute the operation. It was performed in accordance with the requirements of the client, warranty surveyors, shipyard and port authorities and environmental regulations.

Each drydock was safely transported from the fabrication facility to the quayside, then loaded out onto the floating dock using 96 axle lines of Self-Propelled Modular Transporter (SPMT), before being floated off successfully at the right time and tide.

Commenting on the operation, CMN’s Transfer of Technology manager said: “Congratulations to the entire Mammoet team and its subcontractors that have worked so hard during these days. We have been planning this operation together for some time but due to the COVID19 pandemic we had to be inventive and find solutions and avoid delays. The job was well done. Pleasure to have been working with such a great partner as Mammoet.”

Volvo-CE_realtimetechsupport_1000x600.jpg

June 20, 2021 valueeng0

Volvo Construction Equipment (Volvo CE) has introduced a Real-time Tech Support app with which dealer field technicians can communicate directly with Volvo product experts and engineers while on site.

The app, available in the Middle East, along with Africa and Oceania, allows field technicians to use their mobile phones to initiate an interactive video call with their dealer back-office staff and invite a Volvo product expert and engineer, if required, to provide more expertise in diagnosing and resolving an issue.

The augmented reality technology allows all parties involved to see exactly what the field technicians sees and point to components on the screen. Furthermore, these calls can be recorded and saved for reference in case further investigation is required.

Aram Ibrahim, head of Uptime Support at Volvo CE, said: “In the past, when a field technician needed more help to diagnose and fix an issue, they might take some photos, go back to the dealership and talk to colleagues or arrange a call with the Volvo product support team. This could result in multiple visits to the job-site and frustrating downtime for the customer.

“Now, field technicians can benefit from the expertise of their colleagues as if they were at the customer’s site with them. Up to four people can all see and discuss the same component, point to certain things on the screen, make suggestions to try this and that and see the behaviour of the machine in real time. We speed up fault-tracing, minimize travel and get the machine back on the job much sooner.”

Volvo CE said in statement that even the most durably designed machines will experience the occasional technical issue and strong teamwork between manufacturers and dealers is essential to resolve them as quickly as possible, safeguarding customers’ productivity and profitability.

“Volvo CE and its dealers are committed to close and efficient collaboration as one extended enterprise and over the last few years have implemented a common case handling system. This has significantly improved dealer service technicians’ access to information and support and resulted in more vital feedback reaching Volvo R&D teams,” said the statement.

Ibrahim added: “Real-time Tech Support is the next step in our collaboration together for industry-leading uptime. It is also a part of our digitalization journey and we are excited to see how this could pave the way for future technologies like smart glasses or the ability to see inside structures. But for the moment, Real-time Tech Support will improve our efficiency even more and maximize machine uptime.”
