SECTOR REPORT | SUBSEA & OFFSHORE
SCANDINAVIA Earlier in the year, Deme Offshore, an offshore energy contractor, and Liftra announced that they will join forces to develop a novel offshore installation methodology for the next generation of offshore wind turbine generators. The Liftra crane technology will be fully integrated on board Deme’s vessels on an exclusive basis. Denmark-based Liftra is providing the design and engineering, based on its patented LT1500 Turbine Installation Crane technology, and this is combined with Deme Offshore’s engineering, operations and installation technology. Deme says the Offshore Turbine Installation Crane offers the possibility of erecting higher and heavier turbines using existing vessels at a lower cost, while at the same time reducing the environmental footprint, and is suitable for both bottom- fixed and floating turbines. Bart de Poorter, general manager, Deme Offshore Renewables, says: “Deme Offshore is excited to again bring a game- changing installation concept to the industry. Our exclusive partnership with Liftra combines the best of both worlds: Deme Offshore’s expertise and our long track record of successful wind turbine installation with Liftra’s crane technology. There are many advantages of this new joint technology, 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. 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.” Per Fenger, CEO of Liftra, adds: “This
offshore partnership with Deme Offshore underlines that Liftra’s lifting and transport technology is state of the art, also in the offshore wind sector. Liftra is proud to contribute with our innovative LT1500 installation crane technology, which is based on ten years of self-hoisting crane product experience, and the special configuration with two cranes working in parallel, is also proven and goes back many years. “Liftra very much looks forward
to collaborating with Deme on this new offshore turbine installation methodology. Liftra cranes always incorporate an extremely compact
design and are well-known for their efficiency and sustainable set-up. Liftra is thrilled to team up with Deme, given its entrepreneurial drive and proactivity to bring state-of-the-art offshore solutions to the wind turbine industry.” Deme says that due to its flexibility, the
system can be exclusively integrated for use on board its floating offshore heavy- lift vessels such as Orion or Green Jade, as well as its existing jack-up vessels. The partners will develop and integrate
the technology in stages and following a testing programme the new system is expected to be operational in 2027. Staying in Scandinavia, we turn from Denmark’s Listra to the Norwegian offshore crane supplier Red Rock. At the start of autumn the Red Rock service team was busy with commissioning three cranes for a vessel belonging to service vessel operator North Star that will see service at Equinor’s Dogger Bank wind farm project off the north-east coast of England. The three cranes are a 2.0t 3d Motion Compensated Crane, a 2.0t Boat Landing Offshore Crane, and a 1.0t service crane. Meanwhile, Huisman, which
manufactures and services heavy construction equipment, has been awarded a contract from Norwegian vessel operator Havfram Wind, an installation contractor for offshore wind turbines, for the delivery of two packages of auxiliary cranes for both of the company’s NG-20000X-HF Wind Turbine Installation Vessels currently under construction at CIMC Raffles Shipyard in China.
