SEA CHALLENGER

Heavy Maintenance and Construction

4C Offshore | SEA CHALLENGER
SEA CHALLENGER is the sister vessel to SEA INSTALLER. The increased lifting capacity was designed to meet the trend toward even larger turbines, capable of carrying and installing up to eight 4MW turbines of four 6-8MW turbines in a single transit, as seen at Gode Wind 1 and 2. Sea trials started Feb 2014. The vessel has two client offices with six work stations. The vessel's crane was upgraded during construction to increase the reach. The cost of the vessel was reported as $155m.

In early December 2018, the vessel carried out sea trials for floating wind farm sites.

In 2025, the vessel will be reflagged to Japan as part of the joint venture between Penta-Ocean and DEME.
