DEME Offshore and Liftra ApS have recently announced their collaboration in developing an innovative offshore installation methodology for the next generation of offshore wind turbine generators. This novel approach, called the Liftra crane technology, will be exclusively integrated into DEME's vessels, offering several benefits, including cost savings and a reduced environmental footprint.
Liftra, based in Aalborg, is responsible for the design and engineering of the LT1500 Turbine Installation Crane technology, which is combined with DEME's engineering, operations, and installation technology. The resulting Offshore Turbine Installation Crane enables the installation of higher and heavier turbines using existing vessels at a lower cost, while also reducing the environmental impact. This technology is suitable for both bottom-fixed and floating turbines, making it an extremely flexible solution.

Bart de Poorter, General Manager DEME Offshore Renewables, explained that the new joint technology has many advantages. “The major one being the ability to install fixed or floating turbines from a floating vessel, which naturally means there are no limitations regarding water depth,” he said. “As well as this, there are no longer any lifting height issues and relative motions at high heights can be controlled. This new method also reduces the environmental footprint on the seabed at the wind farm's location and in port.”
The system's flexibility allows it to be exclusively integrated into DEME's floating offshore heavy-lift vessels, such as the ‘Orion' or ‘Green Jade', as well as its existing jack-up vessels. The partners plan to develop and integrate the technology in stages, with the pioneering new system expected to be operational in 2027, following an extensive testing program.
