In September Amber Rudd refused development consent for the Navitus Bay Wind Park, which would have comprised up to 194 wind turbines with an installed capacity of up to 970MW.
The refusal was in line with a recommendation from the Planning Inspectorate.
A statement issued today by the developer behind the scheme, Navitus Bay Development Limited, said that "after careful consideration" it had chosen not to challenge the refusal.
The statement said that, over the course of the project, data had been gathered from a wide range of offshore surveys and studies which could be used to "stimulate research, support academia and contribute towards the sustainable management of the seabed".
It said this would now be made publicly available as a "legacy" to the scheme.
