Abstract Atlantic Shores Offshore Wind is developing one of the largest offshore wind energy projects along the U.S. East Coast. Given the large lease area covering 741 km2 and with minimal pre-existing geophysical, geotechnical, environmental, and marine archaeological data availability when the lease was awarded, significant front-end efforts were required to complete project design and regulatory site characterization. Collection of the information needed to progress the Construction Operations Plan and develop a project's detailed design parameters would typically take up to 4 years to finalize. This long duration is exacerbated by the misaligned timing of geophysical information needed early for permitting purposes compared to detailed geotechnical information acquired later, when project design essentials are better defined. This timing issue was managed through innovative phasing and integration of geoscience efforts in the first few years of the development. Coordinated acquisition of geohazards, geophysics, marine archaeology, geotechnics, and benthic habitat data, designed to cover the range of project variables within the project design envelope, optimized the survey campaign and resulted in a future-proof site characterization baseline. This case study highlights various technological, operational and strategic innovations implemented in the following areas: fisheries management and simultaneous vessel operations (SIMOPS), survey line planning, environmental and b...
