About this file
This document is an attachment detailing the shell plating doubler requirements for the Steam Tug Hercules, which is referenced in a federal contract opportunity. The attachment provides a detailed overview of the work required, including the locations, dimensions, and corrosion percentages for various shell plates and doublers that need to be installed or repaired on the starboard and port sides of the vessel, from the stem to frame 77. The work is necessary to facilitate the vessel's safe return to the water. The related federal contract opportunity is for follow-on work for the Hercules Tugboat at Bay Ship & Yacht for the San Francisco Maritime National Historical Site, issued by the Department of the Interior National Park Service.
