< PreviousT he Liebherr HS 8070.1 duty cycle crawler crane has a lifting capacity of 70 tonnes and is designed for material handling, deep foundation work or lifting work. Using the new self-loading system (jack-up system), the crawlers can be easily disassembled for transportation, thus reducing the transport weight to less than 35 t. The platforms and railings need not be removed before transporting. Instead of a single counterweight, the machine now has a modular system. The duty cycle crawler crane can be individually equipped depending on the application. Further, the boom of the HS 8070.1 is compatible with the HS 8100.1. Therefore, customers can use attachments such as the slurry wall grab HSG 5-18 on both machines and install thicker slurry walls with a more compact machine. As opposed to the fi xed system, the new fl oating A-frame system ensures higher performance in dynamic applications. It also simplifi es and speeds up the assembly and transportation of the machine. The user-friendly design extends to the tank neck, which is easily accessible via a platform on the uppercarriage. T he Liebherr LR 1200.1 unplugged and the LR 1250.1 unplugged are the world’s fi rst battery-powered crawler cranes. Both are driven by electric engines with a system performance of 255 kW. The LR 1200.1 unplugged has a maximum lifting capacity of 200 tonnes and the LR 1250.1 lifts 250 tonnes. The new machines are emission free and have a very low noise level, which are huge advantages in areas sensitive to noise and also for the people working on the jobsite. The blue accent in the colour composition, which lends the distinctive look to the unplugged series, symbolises the electric solution representing an advanced technology. The cranes can be recharged on a conventional jobsite electric supply (32 A, 63 A) in 4.5 hours and optionally with 125 A in 2.25 hours. The capacity of the battery is designed for 4 hours lifting operation. In accordance with their name, the cranes can be operated without a cable, thus ‘unplugged’ with the help of the battery-electric drive design. “With our unplugged cranes, we off er our customers an alternative drive design. As we have already seen with the LB 16 unplugged, the fi rst battery-powered drilling rig, the strategy is a complete success. Strict requirements regarding environmental sustainability in tenders for construction projects increase the demand for advanced technologies. For us, it was clear that we extend and successfully establish the design in further product groups,” said Gerhard Frainer, managing director – sales, Liebherr- Werk Nenzing. LIEBHERR INTRODUCES BATTERY-POWERED CRAWLER CRANES THE NEW GENERATION LIEBHERR HS HS 8070.1 OFFERS FLEXIBILITY IN ASSEMBLY AND TRANSPORTATION 40 PLANT / MACHINERY / VEHICLESwww.pmvmiddleeast.comJANUARY 2021 CRANESC onstructing fl oating production storage and offl oading (FPSO) and fl oating liquefi ed natural gas (FLNG) modules onshore has allowed EPCs and owners to expedite project schedules and increase cost-eff ectiveness. By constructing the hull and topsides simultaneously and at greater scale, the time to fi rst production has been reduced. As these components grow, their effi ciency rises, but so does the challenge of their integration. The sheer size of these modules lies on the edge of what modern lifting technology can achieve, both from the land and the water, regularly breaking the 3,000t barrier and measuring tens of thousands of cubic meters. Given the loads involved, it can be diffi cult to fi nd adequate lifting technology close to the project site. Limitations on lifting capacity force engineers to fabricate smaller modules than would be optimal, tying up site space and increasing the complexity and duration of projects. This limitation can also narrow the execution choices available during each project’s planning stage and the percentage of each project that can be executed locally. The Mammoet SK6,000 off ers a maximum lift capacity of up to 6,000t, enabling EPCs and owners to consider construction methodologies involving heavier components than ever before, stretching to 5,000t and beyond. Its proven technology allows the topside modules to be lifted and installed from one single position without any need to rotate the hull, which is a costly and time-consuming exercise. The SK6,000 utilizes the same design as the SK 190 and SK 350 before it, occupying a similar overall footprint to its predecessors. A centralized ballast eliminates the need to install a full ring track. This frees up site space by up to 45%, allowing operations around the crane to continue and the FPSO to launch faster. As the SK6,000 is containerized and can be assembled quickly on site, it can deliver heavy lift capability to wherever it is needed. This provides greater fl exibility in where and how projects are completed, and therefore, allows new standards to be set in effi ciency, safety, and time to production. Giovanni Alders, sales director, Mammoet, said: “As our customers strive for greater and greater effi ciencies, both in terms of construction and production, the capacity of land-based cranes becomes a signifi cant limiting factor when developing the FPSO modularization strategy. As FPSO designs scale-up, not only are module designs growing larger and heavier, but fl are towers are also becoming taller than ever before. With our SK6,000, we can install fl are towers of up to 1,500t and 150m in height in a single piece. Our customers can think bigger than ever before, pushing modules beyond the 4,000t and even 5,000t barriers. Its low ground bearing capacity also means the crane can be used all over the world. With its long outreach, small minimum footprint and relatively small site impact, the SK6,000 greatly reduces the topside integration time. Needless to say, with larger building blocks you spend less time connecting and testing, and more time producing.” MAMMOET’S 6,000T CRANE ENHANCES FPSO MODULARIZATION STRATEGIES 41 PLANT / MACHINERY / VEHICLESwww.pmvmiddleeast.comJANUARY 2021 CRANEST he Red Sea Development Company (TRS- DC), the developer of the world’s most am- bitious regenerative tourism project, has awarded a contract to global engineering fi rm Mott MacDonald to provide consultancy servic- es to determine the optimal sustainable vehicle and fl eet confi guration at the destination. Mott MacDonald will deliver a comprehensive and robust analysis of the total land, sea and air transport needs for the development and opera- tion of the 28,000km² site, from its opening in 2022 to its completion in 2030. This will involve a strategy for destination-wide clean mobility using electric and hydrogen vehicles, boats and aircrafts. John Pagano, CEO of TRSDC, said: “We believe that environmental regeneration and commercial development do not have to be mutually exclusive. Our destination is one of extraordinary natural beauty, which we have a responsibility to protect and enhance for future generations. We’re looking forward to working with Mott MacDonald, who are well aligned with our strong sustainability ambitions to de- liver a green mobility plan and will support us with our commitment to become a carbon neu- tral destination. The company will also be required to identify the most appropriate supporting infrastructure, such as electric and hydrogen vehicle charging stations, in line with TRSDC’s ambitions to power the destination with 100 percent renew- able energy. The appointment is a key development in the roll out of Phase One, which is well underway. Vehicle fl eet to be assessed include e-bikes, golf buggies, cars, vans, trucks, buses, seaplanes, helicopters, VTOL, passenger ferries, boats, maintenance vehicles, airside vehicles and even off -road leisure pursuit vehicles. Mott MacDon- ald will also propose the best fl eet propulsion systems from a range of available sustainable options. Chris Seymour, Middle East managing direc- tor at Mott MacDonald, said: “At Mott MacDon- ald, we embed the key aspects of sustainable development into all our projects and business activities. Sustainable development is a matter of making choices and decisions that satisfy all relevant social, economic and environmental concerns, and is an area where TRSDC is setting new standards. We’re looking forward to being part of shaping this beautiful destination and supporting TRSDC’s progressive sustainability initiatives.” As part of TRSDC’s commitment to go be- yond sustainability to actively enhance the des- tination, the project will be powered with 100 percent renewable energy, 24 hours a day via so- lar and wind power, an accomplishment which has never been achieved on a project of this scale before. TRSDC is investing in a number of innova- tive nature-based solutions throughout the construction process, to not just prevent envi- ronmental damage, but positively contribute to the area’s delicate ecosystems. A central part of this approach is the aim to increase the project’s net conservation benefi t by 30 percent by 2040. In line with the development of the sustain- able management plan, TRSDC will be partner- ing with leading vendors who demonstrate a proven track record and commitment to innova- tion and sustainability. Considerable progress has been made on The Red Sea Project, despite Covid-19 related disrup- tions in 2020. Approximately 500 contracts have been awarded so far at a value of SAR 12 billion (nearly $3.2 billion) – set to rise to nearly SAR 15 billion by the end of 2020. The project has surpassed signifi cant mile- stones and work remains on track to welcome the fi rst guests by the end of 2022, when the international airport and the fi rst four hotels will open. The remaining 12 hotels scheduled for completion in Phase One will open in 2023, delivering a total of 3,000 rooms across fi ve is- lands and two inland resorts. Upon completion in 2030, the Destination will include 50 hotels off ering up to 8,000 hotel rooms and 1,300 resi- dential properties across 22 islands and six in- land sites.
