OEG Renewables supplied owned and chartered CTVs to the project, with two operating at one time; both the Manor Endurance and Manor Venture were on site. OEG Renewables chartered three SOVs during the duration of the project, including the Normand Fortress, Acta Orion and Horizon Star.
Approximately 90 personnel worked on the project throughout the work scope; at peak, 58 personnel were on shift including both on and offshore roles. OEG Renewables' dedicated project office in Hull supported the operations on Hornsea Two and provided a storage space for the generator sets.
All generators sets were demobilised by September 2022.
