Case Study

Long Island offshore wind park

Offshore wind turbines

Advisian (operating as Intecsea) was contracted to provide general Owner’s Engineer services and technical assessment, offshore engineering and offshore project management expertise and advice for the overall development of the Long Island Offshore Wind Park.


The primary focus was to prepare the technical elements of the permit application.


Scope requirements included RFP preparation for geohazard and geotechnical site investigation surveys, cost estimates for monopile and gravity based foundation concepts (including procurement, fabrication, construction, and installation costs), and furnish technical recommendations for installation methods and contracting approaches. A GIS database was created and maintained describing seabed topology, geohazards and other features.
