The work scope for the Hornsea One Offshore Wind Farm includes welfare provision for the full five-year operation and maintenance (O&M) campaign and, to deploy all units via the O&M service vessel (SOV) rather than by conventional crew transfer vessel (CTV).

The units were assigned to both Orsted and Siemens service teams to transfer. As well as the welfare units, kit bags and equipment were transferred to the asset worked on each day.
