Neoen has completed turbine installation at its 157MW Kaban Green Power Hub in Queensland, Australia, with the help of Mammoet’s lifting technology.
Mammoet has been involved in the installation of 28 Vestas EnVentus V162-5.6MW units at a remote site in the Atherton Tablelands in north Queensland, marking the first time these turbines have been installed in the country.
Working alongside Vestas’ mechanical and electrical installation teams, Mammoet assisted in the lifting and assembly of turbine components, including tower sections, nacelles, powertrains, hubs, and blades.
The assembled turbines stand at a tip height of 226 metres.
Mammoet used a Terex Demag AC700 crane for the combined offloading and preassembly scope.
This 700-tonne capacity hydraulic crane was engineered to set up in a single optimal position, which enabled a two-stage offloading process with intermediate preassembly.
This approach decreased the number of teams required on-site from three to two, and minimised crane movements needed between lifts, “resulting in significant time and cost savings”.
Mammoet’s LG 1750SX, equipped with a 151-metre main boom and 12-metre fixed fly, was used to lift and install the EnVentus powertrains, each weighing 92 tonnes, to a hub height of 149 metres.
A fleet of Scheuerle SPMT and Goldhofer THP multi-axle trailers were used to manoeuvre 400 tonnes of superlift counterweight at once, supporting the LG1750 installation, and up to 280 tonnes of counterweight at once during on-site relocations.
This method not only accelerated operations but also reduced the number of truck and trailer trips, minimising the project’s carbon footprint.
Sales executive manager, Mammoet Australia, Bjorn-Evert Van Eck Rasmussen said: “The company’s long-established presence in Australia, extensive fleet of equipment and vast expertise in onshore wind farm projects, positioned us as the ideal partner for the project.
“With a strong focus on sustainability, we brought a new level of expertise to the table.
“Through our collaborative efforts with Neoen, Vestas and the other project stakeholders, we played a part in driving the transition to clean and green energy in Far North Queensland.”
