Fire Island

The purpose of this project was to install two submarine cables 3.2 miles between Anchorage and Fire Island as part of the Fire Island Wind project. The cables were to be installed a minimum of ten feet apart and to a minimum depth of 5 feet.  The work included intertidal burial, onshore burial, an ACS fiber optic crossing, and final acceptance testing.  The cables were installed utilizing two barges.  A cable barge with a cable gantry system designed and installed by Cruz Construction was utilized to store and feed the cable during installation.  An equipment barge was used to deploy and retrieve floating and tracked excavators at low tide for installation of the cables using standard excavation methods.
