OUYANG Offshore has awarded AqualisBraemar the construction supervision contract for two newbuild self-elevating wind turbine installation vessels to be constructed at Chinese shipyard Dayang Offshore Equipment.

Yongfei Peng, China country manager for AqualisBraemar, said, “Having previously supervised construction of the OuYang 001 and OuYang 002 wind turbine installation vessels, it is a huge vote of confidence to be engaged for OuYang 003 and OuYang 004 too”.

AqualisBraemar’s on-site team at Jiangsu-based Dayang Offshore Equipment will monitor and supervise the construction of the two wind turbine installation vessels – OuYang 003 and OuYang 004 – to ensure that all work is carried out in accordance with the contract specifications plus flag and class requirements.

Both units are identical, 75.6 metres in length, 40 metres in beam, seven metres in depth, four hydraulic pin legs self-elevating wind turbine installation vessels. Both units are self-propelled, with an operational water depth of up to 50 metres and accommodation for up to 68 persons. Both units are equipped with one 600MT leg fitted crane around one of stern legs, with a lifting height of 140 metres from sea level. With the spacious main deck, both units are capable of the lifting installation of 10MW wind turbines in China. 


AqualisBraemar and its sister company OWC (Offshore Wind Consultants) are increasingly being asked to support offshore wind projects in Chinese waters. Recently, the companies have been engaged with both the Jiangsu and Guangdong offshore wind projects.

AqualisBraemar and OWC are part of Oslo-listed energy consultancy group AqualisBraemar ASA.
