Integrated ABB power and propulsion package will support Allseas’ new semi-submersible Grand Tour in Europe’s growing offshore wind logistics chain
ABB has secured a contract with Guangzhou Shipyard International to supply an integrated power and propulsion package for Grand Tour, a new semi-submersible heavy transport vessel (HTV) being built for global offshore contractor Allseas.
The 230-metre vessel is scheduled for delivery in 2028 and will support the growing logistics requirements of Europe’s offshore wind industry, transporting large offshore power converter stations from fabrication yards in Asia and Europe directly to Allseas’ construction vessel Pioneering Spirit for installation.
Power, control and manoeuvrability are key vessel attributes for Grand Tour, which will carry loads of up to 40,000 metric tons on its stern deck and position itself alongside Pioneering Spirit while lowering its main deck below the waterline to float converter stations directly onboard.
ABB’s supply includes four 3.5MW nozzled Azipod® units, providing sufficient thrust to serve Grand Tour’s bollard pull and dynamic positioning (DP) needs. Rotating 360 degrees, Azipod® propulsion will support precise maneuvering into position at Pioneering Spirit’s bow. The units will be equipped with optimized nozzles to ensure high efficiency also during transit. Gearless Azipod® units reduce mechanical losses and fuel consumption – thereby helping to reduce emissions – as well as noise and vibration compared to conventional mechanical thrusters. In addition, the gearless design helps to minimize the need for lubrication oil, reducing the need for maintenance and thereby lowering operating costs. The technology’s compact footprint provides flexibility in design and facilitates efficient installation.
The full ABB package includes a medium-voltage AC power plant in a closed ring topology, controlled by PEMS™ power and energy management system and enhanced power plant protection system (EPPS). The full-scope powertrain solution is complete with remote condition monitoring and maintenance capabilities.
“Grand Tour demonstrates Guangzhou Shipyard’s capabilities in delivering even the most complex vessels and marks another exciting collaboration with our long-standing and trusted partner, ABB,” said Zhou Xuhui, President, Guangzhou Shipyard International.
“It’s fantastic to see our power and propulsion technology delivering such strong value in demanding heavy‑lift operations,” said Rune Braastad, President, ABB’s Marine & Ports division. “Projects like this demonstrate how advanced, integrated systems can make operations leaner, cleaner and more efficient, raising performance and safety to a new level, while also opening new market opportunities.”
