Ro/Ro-loading of Rentel wind turbine nacelles

Siemens Gamesa Renewable Energy (SGRE) has now fully implemented its cutting-edge offshore logistics concept announced in late 2015: After the establishment of a blade plant in the harbor of Hull, England in 2016 and the opening of a nacelle factory in Cuxhaven, Germany in 2017, the company eliminated road transportation of large and heavy wind turbine components from factories to installation harbors. With the first load of nacelles shipped from Cuxhaven to the Belgian offshore wind power plant Rentel on the purpose-built transport ship Rotra Vente, SGRE’s Ro/Ro logistics concept is now fully functional. Compared to the former setup including road transportation and crane loading, SGRE significantly increases safety while saving approximately 20 percent in logistics costs. The concept is aligned to the offshore cost-out measures as part of the business strategy presented by Siemens Gamesa at the Capital Market Day in February.
One key element of this advanced transport solution is the efficient link between Siemens Gamesa’s offshore production locations in Cuxhaven, Germany, and Hull, England, provided by two purpose-built transport vessels. Another is the new process of loading and unloading these ships: Instead of lifting tower sections of up to 200 metric tons and nacelles weighing around 400 tons by crane, the large and heavy components are rolled on and off of these vessels. This “Roll-on/Roll-off” process is known as Ro/Ro. Siemens Gamesa has utilized this method inside its plants for many years. Based on this experience, the company’s experts further refined the concept together with deugro, an international forwarder in the capital project and heavy lift field. Tailor-made transport frames are used to store and move the nacelles. These transport structures are mounted under the bedframe of the nacelles, and can be carried by Self-Propelled Modular Transporters (SPMTs). These self-lifting, motorized units feature a large array of wheels, and are remotely controlled by experienced operators.
The two special transport vessels, each with a length of approximately 140 meters, are also operated by deugro Danmark A/S exclusively for Siemens Gamesa. The Rotra Vente, which has now been loaded in Cuxhaven can transport eight nacelles of the current Siemens Gamesa Direct Drive wind turbine at a time. The second vessel, the Rotra Mare, accommodates three complete wind turbine towers of three sections each or up to 12 rotor blades and transports them from the production facility in Hull, England, or from Aalborg, Denmark, to the respective installation port. Both vessels can also be unloaded by crane if required. This enhances the flexibility of the installation ports, which are selected according to project-specific requirements. Currently both ships use the Ro/Ro capabilities of the harbors on their routes between the UK, Denmark, and Germany to the Rentel installation port in Ostend, Belgium.
Over the next weeks, Siemens Gamesa will provide all 42 SWT-7.0-154 turbines for the Rentel offshore wind power plant. They will be preassembled and installed together with the towers and nacelles from the recently opened installation facility in the Belgian harbor of Ostend. SGRE will also service the Rentel offshore power plant from Ostend, where a service office with an additional 300 square meters of storage is currently under construction. Full commissioning of the Rentel project is expected later this year. The Cuxhaven nacelle plant will deliver the nacelles to the 588 megawatt (MW) Beatrice wind power plant and the 1,218 MW Hornsea One project, both of them located in the British North Sea.

Mammoet begins assembly of world’s biggest land-based crane

SK6000 ring crane redefines modular construction methodologies across heavy industry
Mammoet, the global leader in engineered heavy lifting and transport, has started assembling the world’s strongest land-based crane, the SK6000, at its Westdorpe facility in the Netherlands.
This monumental project marks a new era in heavy lifting technology, offering unprecedented lifting capacity and reach, and opening up new construction methodologies for large projects.
The SK6000 ring crane is testament to Mammoet’s commitment to innovation, but also sustainability. The crane will offer full electric operation. This means it enables the transition to cleaner power sources while driving down the carbon impact of energy projects themselves.
The SK6000 has a maximum capacity of 6,000t, and is capable of lifting components up to 3,000t to a height of 220 meters. Its sheer lifting power allows Mammoet customers to build more efficiently in larger pieces, shrinking the logistics, integration and mobilization phases of projects.
The crane provides a huge leap forward for projects in emerging energy sectors, supporting the continued constructability of next-generation wind turbine and foundation components needed to achieve higher yields from offshore wind farms. It also unlocks new modular construction options for nuclear facilities, with increased cost-effectiveness and safety.
In the oil and gas sector, the SK6000 helps new build and expansion projects to benefit from economies of scale on a level never before seen. It builds on the design philosophy of Mammoet’s SK190 and SK350 series, which are proven in the market.
Following mobilization of all parts to Mammoet’s Westdorpe site, initial works include assembly of the crane’s base frame, power packs and control room. Mammoet’s auxiliary cranes are supporting the build, including two 250-tonne crawler cranes and a 140-tonne Gottwald mobile harbor crane.
Koen Brouwers, Project Manager for the SK6000, said:
“This is a thrilling new chapter for Mammoet and modular construction in heavy industry, as we see the SK6000 taking shape.
It will offer a hook height, outreach, and lifting capacity far in excess of any crane on the market. We are excited to bring this groundbreaking technology to our customers, helping them achieve their project goals with greater efficiency and more sustainably.”
Assembly of the SK6000 is scheduled to be completed during Q4 2024.
