Cosco Nantong, a subsidiary of Cosco Shipyard Group, has delivered state-of-the-art wind turbine installation vessel Sea Challenger to Denmark-based offshore wind farm installation and services company A2SEA. Sea Chalenger measures 132.34 meters in LOA, 39 meters in breadth and 9 meters in depth. Optimised to operate at depths of up to 45 metres, the vessel is well suited for installation of the upcoming offshore wind projects in the Northern Europe.

This is the second jack-up vessel that Cosco Shipyard has built for A2SEA, almost identical to its sister ship, the Sea Installer. However, Sea Challenger features a larger crane that can lift up to 900 tonnes – 100 tonnes more than her sister vessel. The increased lifting capacity will meet the trend toward even larger turbines engineered for offshore use. The first work for Sea Challenger will be on Dong Energy’s Westermost Rough project.
