ABB will supply the integrated power and propulsion system for Grand Tour, a new 230-meter semi-submersible heavy transport vessel being built by Guangzhou Shipyard International (GSI) for offshore contractor Allseas. Scheduled for delivery in 2028, Grand Tour is designed to transport large offshore wind converter stations from fabrication facilities in Asia and Europe and transfer them directly to Allseas’ heavy construction vessel Pioneering Spirit for offshore installation. Converter stations play a central role in long-distance offshore wind power transmission, converting AC electricity generated by wind turbines into DC power for transmission to shore. ABB’s propulsion package centers on four 3.5-MW nozzled Azipod units, providing a combined 14 MW of propulsion power. Grand Tour will ultimately serve as a specialized logistics link supporting Allseas’ growing role in Europe’s offshore wind construction market.
