prices, the 90 turbine 857MW installation is expected (September 2021) to cost some £2 billion. Construction timeline 2018. Initial onshore construction started in 2018, with main construction of the substation and cable route planned for late summer 2018. September 2018. J Murphy and Sons began construction of the on-shore cable route from Anderby Creek to the substation at Bicker Fen, near Boston, Lincs. Work on the substation began in early 2019, and was completed by Siemens Energy in Autumn 2020. Resintatement and landscaping for the cable route and substation were finalised in Spring 2021. January 2020: Offshore construction began with installation of the first turbine foundation on 22 January 2020 by the Seaway 7's Strashnov vessel, which, in conjunction with heavy lift vessel DEME Innovation, installed all 90 monopile 54 metre steel foundations by late August 2020. April 2020. Installation of the two offshore substation platforms (OSPs) designed by Siemens Energy June 2020. Completion and opening of the Operations and Maintenance Base in Grimsby. August 2020. Two 50 km cable circuits were laid from the offshore substations to the landfall at Anderby Creek, Lincolnshire. They were laid and plough-buried by the Boskalis cable-laying vessel NDurance. January 2021. First turbine installed. The turbine blades are manufactured on the Isle of Wight by MHI-Vestas, and the turbines are manufactured at Lindø. They are brought to the construction centre at Seaton Port, near Hartlepool, by a purposebuilt cargo ship. March 2021. With the offshore and onshore substations completed, first power was announced on 1 March 2021. June 2021. Half-way point for turbine installation is reached, with 45 of the planned 90 turbines installed by 8 June, using theDEME's jack-up vessel 'Wind Osprey'. September 2021. 90th and final turbine was announced as having been installed, completing the 857MW array.
